    (220 ILCS 5/9‑101) (from Ch. 111 2/3, par. 9‑101)
    Sec. 9‑101. All rates or other charges made, demanded or received by any product or commodity furnished or to be furnished or for any service rendered or to be rendered shall be just and reasonable.

All rules and regulations made by a public utility affecting or pertaining to its charges to the public shall be just and reasonable.

    (220 ILCS 5/9‑102) (from Ch. 111 2/3, par. 9‑102)
    Sec. 9‑102. Every public utility shall file with the Commission and shall print and keep open to public inspection schedules showing all rates and other charges, and classifications, which are in force at the time for any product or commodity furnished or to be furnished by it, or for any service performed by it, or for any service in connection therewith, or performed by any public utility controlled or operated by it. Every public utility shall file with and as a part of such schedule and shall state separately all rules, regulations, storage or other charges, privileges and contracts that in any manner affect the rates charged or to be charged for any service. Such schedule shall be filed for all services performed wholly or partly within this State, and the rates and other charges and classifications shall not, without the consent of the Commission, exceed those in effect on December 31, 1985. But nothing in this section shall prevent the Commission from approving or fixing rates or other charges or classifications from time to time, in excess of or less than those shown by said schedules.
    Where a schedule of joint rates or other charges, or classifications is or may be in force between two or more public utilities such schedules shall in like manner be printed and filed with the Commission, and so much thereof as the Commission shall deem necessary for the use of the public shall be filed in every office of such public utility in accordance with the terms of Section 9‑103 of this Act. Unless otherwise ordered by the Commission a schedule showing such joint rates or other charges, or classifications need not be filed with the Commission by more than one of the parties to it: Provided, that there is also filed with the Commission a concurrence in such schedule by each of the other parties thereto.
    Every public utility shall file with the Commission copies of all contracts, agreements or arrangements with other public utilities, in relation to any service, product or commodity affected by the provisions of this Act, to which it may be a party, and copies of all other contracts, agreements or arrangements with any other person or corporation affecting in the judgment of the Commission the cost to such public utility of any service, product or commodity.

    (220 ILCS 5/9‑102.1)
    Sec. 9‑102.1. Negotiated rates.
    (a) Notwithstanding anything to the contrary in any other Section of Article IX of this Act, the Commission may approve one or more rate schedules filed by a public utility that enable the public utility to provide service to customers under contracts that are treated as proprietary and confidential by the Commission notwithstanding the filing thereof. Service under the contracts shall be provided on such terms and for such rates or charges as the public utility and the customer agree upon, without regard to any rate schedules the public utility may have filed with the Commission under any other Section of Article IX of this Act. The contracts shall be filed with the Commission, notwithstanding anything to the contrary in any schedule referred to in subsection (b) of this Section. For purposes of Section 3‑121 of this Act, the amounts collected under the contracts shall be treated as having been collected under rates that the public utility is required to file under Section 9‑102 of this Act.
    (b) Each schedule described in subsection (a) that became effective before August 25, 1995, and any contract thereunder, shall be deemed to have become effective in accordance with its terms, subject to the provisions of any Commission order that purported to authorize the schedule.
    (c) In any determination of the rates to be charged by an electric public utility having contracts in effect pursuant to schedules filed under this Section or schedules referred to in subsection (b) of this Section, the revenues received, or to be received, by the electric public utility under each such contract shall be deemed to be equal to the revenues, based on the actual usage of the customer, that would have been, or would be, received under the lowest rates available under schedules on file pursuant to Section 9‑201, applicable to a class of consumers that includes the customer, including any applicable riders or surcharges, plus any revenues that would have been, or would be required to pay for investment or expenses incurred by the electric public utility that would not be incurred if service were provided under such lowest rates. The cost of capital used to determine rates to be charged by the electric public utility shall be that which would have obtained if service were provided under such lowest rates. The provisions of this subsection (c) shall not apply: (1) in any determination of the rates to be charged by a gas public utility, and (2) in any determination of the rates to be charged by an electric public utility, to contracts in effect prior to the effective date of this amendatory Act of 1996 pursuant to economic development schedules referred to in Section 9‑241 of this Act, under which the electric public utility is authorized to provide discounts for new electrical sales that result from the location of new or expanded industrial facilities in the electric public utility's service territory. The preceding sentence shall not be construed to diminish the Commission's existing authority as of the effective date of this amendatory Act of 1996 to allocate the costs of all public utilities equitably, in any determination of rates, so as to set rates which are just and reasonable.
    (d) Any contract filed pursuant to the provisions of subsection (a) of this Section shall be accorded proprietary and confidential treatment by the Commission and otherwise deemed to be exempt from the requirements of Sections 9‑102, 9‑103, 9‑104, 9‑201, 9‑240, 9‑241, and 9‑243, except to the extent the Commission may, in its discretion, order otherwise. The Commission shall permit any statutory consumer protection agency to have access to any such contract, provided that: (i) the agency, and each individual that will have access on behalf of the agency, agree in writing to keep such contract confidential, such agreement to be in a form established by the Commission; and (ii) access is limited to full‑time employees of the agency and such other persons as are acceptable to the public utility or, if the agency and the public utility are unable to agree, are determined to be acceptable by the Commission. "Statutory consumer protection agency" means any office, corporation, or other agency created by Article XI of this Act or any other Illinois statute as of the effective date of this amendatory Act of 1996 that has an express statutory duty to represent the interest of public utility customers, any such agency subsequently created by act of the General Assembly that expressly authorizes the agency to access the information described in this subsection, or the Attorney General of the State of Illinois.
    (e) Nothing in this Section shall be construed to give a public utility the authority to provide electric or natural gas service to a customer the public utility is not otherwise lawfully entitled to serve. Nothing in this Section shall be construed to affect in any way the service rights of electric suppliers as granted under the Electric Supplier Act.
    (f) The provisions of subsection (b) of this Section 9‑102.1 are intended to be severable from the remaining provisions of this Act; and therefore, no determination of the validity of the provisions of subsection (b) shall affect the validity of the remaining provisions of this Section 9‑102.1.
    (g) After January 1, 2001, no contract for electric service may be entered into under any schedule filed pursuant to the provisions of subsection (a) of this Section or under any schedule referred to in subsection (b) of this Section. The foregoing provision shall not affect any contract entered into prior to January 1, 2001.
    (h) Nothing contained in this Section shall be construed as preventing any customer or other appropriate party from filing a complaint or otherwise requesting that the Commission investigate the reasonableness of the terms and conditions of any schedule filed under this Section or referred to in subsection (b) of this Section. Nothing contained in this Section shall be construed as affecting the right of any customer or public utility to enter into and enforce any contract providing for the amounts to be charged for service where the contract is or has been filed pursuant to any other Section of this Act. Nothing contained in this Section shall be construed to limit any Commission authority to authorize a public utility to engage in experimental programs relating to competition, including direct access programs.

    (220 ILCS 5/9‑103) (from Ch. 111 2/3, par. 9‑103)
    Sec. 9‑103. Posting of rate schedules. Subject to such rules and regulations as the Commission may prescribe, the schedules referred to in Section 9‑102 shall be posted or kept on file in every office of a public utility where the public transacts business with such public utility. Any or all of such schedules kept as aforesaid shall be immediately produced by such public utility for inspection upon the demand of any person. A notice printed in bold type, in size prescribed by the Commission, stating that such schedules are on file with the agent and open to inspection by any person, and that the agent will assist any person to determine from such schedules any rates or other charges, classification, rules or regulations in force, shall be kept posted by the public utility in two public and conspicuous places in every such office. The form of every such schedule shall be prescribed by the Commission: Provided, that in lieu of filing the entire schedule in each office, any public utility may, subject to the regulations of the Commission, file or keep posted at such office, schedules of such rates or other charges, classifications, rules and regulations relating thereto, as are applicable at, to and from the place where such office is located.
    The Commission may determine and prescribe the form in which the schedules required by this Act to be filed with the Commission and to be kept open to public inspection shall be prepared and arranged, and may change the form from time to time if it shall be found expedient.

    (220 ILCS 5/9‑104) (from Ch. 111 2/3, par. 9‑104)
    Sec. 9‑104. No public utility shall undertake to perform any service or to furnish any product or commodity unless or until the rates and other charges and classifications, rules and regulations relating thereto, applicable to such service, product or commodity, have been filed and published in accordance with the provisions of this Act: Provided, that in cases of emergency, a service, product or commodity not specifically covered by the schedules filed, may be performed or furnished at a reasonable rate, which rate shall forthwith be filed and shall be subject to review in accordance with the provisions of this Act.

    (220 ILCS 5/9‑201)(from Ch. 111 2/3, par. 9‑201)
    Sec. 9‑201. (a) Unless the Commission otherwise orders, and except as otherwise provided in this Section, no change shall be made by any public utility in any rate or other charge or classification, or in any rule, regulation, practice or contract relating to or affecting any rate or other charge, classification or service, or in any privilege or facility, except after 45 days' notice to the Commission and to the public as herein provided. Such notice shall be given by filing with the Commission and keeping open for public inspection new schedules or supplements stating plainly the change or changes to be made in the schedule or schedules then in force, and the time when the change or changes will go into effect, and by publication in a newspaper of general circulation or such other notice to persons affected by such change as may be prescribed by rule of the Commission. The Commission, for good cause shown, may allow changes without requiring the 45 days' notice herein provided for, by an order specifying the changes so to be made and the time when they shall take effect and the manner in which they shall be filed and published.
    When any change is proposed in any rate or other charge, or classification, or in any rule, regulation, practice, or contract relating to or affecting any rate or other charge, classification or service, or in any privilege or facility, such proposed change shall be plainly indicated on the new schedule filed with the Commission, by some character to be designated by the Commission, immediately preceding or following the item.
    When any public utility providing water or sewer service proposes any change in any rate or other charge, or classification, or in any rule, regulation, practice, or contract relating to or affecting any rate or other charge, classification or service, or in any privilege or facility, such utility shall, in addition to the other notice requirements of this Act, provide notice of such change to all customers potentially affected by including a notice and description of such change, and of Commission procedures for intervention, in the first bill sent to each such customer after the filing of the proposed change.
    (b) Whenever there shall be filed with the Commission any schedule stating an individual or joint rate or other charge, classification, contract, practice, rule or regulation, the Commission shall have power, and it is hereby given authority, either upon complaint or upon its own initiative without complaint, at once, and if it so orders, without answer or other formal pleadings by the interested public utility or utilities, but upon reasonable notice, to enter upon a hearing concerning the propriety of such rate or other charge, classification, contract, practice, rule or regulation, and pending the hearing and decision thereon, such rate or other charge, classification, contract, practice, rule or regulation shall not go into effect. The period of suspension of such rate or other charge, classification, contract, practice, rule or regulation shall not extend more than 105 days beyond the time when such rate or other charge, classification, contract, practice, rule or regulation would otherwise go into effect unless the Commission, in its discretion, extends the period of suspension for a further period not exceeding 6 months.
    All rates or other charges, classifications, contracts, practices, rules or regulations not so suspended shall, on the expiration of 45 days from the time of filing the same with the Commission, or of such lesser time as the Commission may grant, go into effect and be the established and effective rates or other charges, classifications, contracts, practices, rules and regulations, subject to the power of the Commission, after a hearing had on its own motion or upon complaint, as herein provided, to alter or modify the same.
    Within 30 days after such changes have been authorized by the Commission, copies of the new or revised schedules shall be posted or filed in accordance with the terms of Section 9‑103 of this Act, in such a manner that all changes shall be plainly indicated. The Commission shall incorporate into the period of suspension a review period of 4 business days during which the Commission may review and determine whether the new or revised schedules comply with the Commission's decision approving a change to the public utility's rates. Such review period shall not extend the suspension period by more than 2 days. Absent notification to the contrary within the 4 business day period, the new or revised schedules shall be deemed approved.
    (c) If the Commission enters upon a hearing concerning the propriety of any proposed rate or other charge, classification, contract, practice, rule or regulation, the Commission shall establish the rates or other charges, classifications, contracts, practices, rules or regulations proposed, in whole or in part, or others in lieu thereof, which it shall find to be just and reasonable. In such hearing, the burden of proof to establish the justness and reasonableness of the proposed rates or other charges, classifications, contracts, practices, rules or regulations, in whole and in part, shall be upon the utility. The utility, the staff of the Commission, the Attorney General, or any party to a proceeding initiated under this Section who has been granted intervenor status and submitted a post‑hearing brief must be given the opportunity to present oral argument, if requested no later than the date for filing exceptions, on the propriety of any proposed rate or other charge, classification, contract, practice, rule, or regulation. No rate or other charge, classification, contract, practice, rule or regulation shall be found just and reasonable unless it is consistent with Sections of this Article.
    (d) Except where compliance with Section 8‑401 of this Act is of urgent and immediate concern, no representative of a public utility may discuss with a commissioner, commissioner's assistant, or hearing examiner in a non‑public setting a planned filing for a general rate increase. If a public utility makes a filing under this Section, then no substantive communication by any such person with a commissioner, commissioner's assistant or hearing examiner concerning the filing is permitted until a notice of hearing has been issued. After the notice of hearing has been issued, the only communications by any such person with a commissioner, commissioner's assistant, or hearing examiner concerning the filing permitted are communications permitted under Section 10‑103 of this Act. If any such communication does occur, then within 5 days of the docket being initiated all details relating to the communication shall be placed on the public record of the proceeding. The record shall include any materials, whether written, recorded, filmed, or graphic in nature, produced or reproduced on any media, used in connection with the communication. The record shall reflect the names of all persons who transmitted, received, or were otherwise involved in the communication, the duration of the communication, and whether the communication occurred in person or by other means. In the case of an oral communication, the record shall also reflect the location or locations of all persons involved in the communication and, if the communication occurred by telephone, the telephone numbers for the callers and recipients of the communication. A commissioner, commissioner's assistant, or hearing examiner who is involved in any such communication shall be recused from the affected proceeding. The Commission, or any commissioner or hearing examiner presiding over the proceeding shall, in the event of a violation of this Section, take action necessary to ensure that such violation does not prejudice any party or adversely affect the fairness of the proceedings including dismissing the affected proceeding. Nothing in this subsection (d) is intended to preclude otherwise allowable updates on issues that may be indirectly related to a general rate case filing because cost recovery for the underlying activity may be requested. Such updates may include, without limitation, issues related to outages and restoration, credit ratings, security issuances, reliability, Federal Energy Regulatory Commission matters, Federal Communications Commission matters, regional reliability organizations, consumer education, or labor matters, provided that such updates may not include cost recovery in a planned rate case.

    (220 ILCS 5/9‑201.5)
    Sec. 9‑201.5. Decommissioning nuclear power plants; rates.
    (a) The Commission may after hearing, in a rate case or otherwise, authorize the institution of rate provisions or tariffs that increase or decrease charges to customers to reflect changes in, or additional or reduced costs of, decommissioning nuclear power plants, including accruals for estimates of those costs, irrespective of any changes in other costs or revenues; provided the revenues collected under such rates or tariffs are used to recover costs associated with contributions to appropriate decommissioning trust funds or to reduce the amounts to be charged under such rates or tariffs in the future. These provisions or tariffs shall hereinafter be referred to as "decommissioning rates".
    (b) A public utility that does not have a decommissioning rate in effect on the effective date of this amendatory Act of 1994 may not place a decommissioning rate in effect before January 1, 1995. Changes in charges under a decommissioning rate shall not be subject to the notice and filing requirements of subsection (a) of Section 9‑201 of this Act, but a decommissioning rate of a utility that does not have such a rate in effect before the effective date of this amendatory Act of 1994 shall provide that no increase in charges under that rate may take effect until 60 days after the utility provides the proposed increased charge to the Commission for review. The Commission may require that a decommissioning rate contain provisions for reconciling amounts collected under the rate with both reasonably projected costs and actual costs prudently incurred. As used in this Section, "decommissioning costs" and "decommissioning trust fund" have the same meaning as in Section 8‑508.1 of this Act.
    (c) Nothing contained in this amendatory Act of 1994 shall affect any determination of the authority of the Commission before the effective date of this amendatory Act of 1994. Nothing contained in this amendatory Act of 1994 shall be used in any determination of the authority of the Commission after the effective date of this amendatory Act of 1994, except with respect to decommissioning rates.
    (d) A decommissioning rate authorized by the Commission under this Section and the decommissioning cost studies underlying the rate shall be subject to hearing and review, in a rate case or otherwise, not less than once every 6 years.

    (220 ILCS 5/9‑202) (from Ch. 111 2/3, par. 9‑202)
    Sec. 9‑202. (a) Whenever the Commission is of the opinion and so finds after an examination of any report or reports, annual or otherwise, filed with the Commission by any public utility, together with any other facts or information which the Commission may acquire or receive from an investigation of the books, records or papers or from an inspection of the property of such public utility, that the net income of such public utility after reasonable deductions for depreciation and other proper and necessary reserves, is in excess of the amount required for a reasonable return upon the value of said public utility's property used and useful in rendering its service to the public, provided however that in computing net income, deductions shall not be made for advertising expenses as prohibited under Section 9‑225 of this Act, and if the Commission is of the opinion and so finds in said cause that a hearing to determine all of the issues involved in a final determination of rates or services will require more than 105 days of elapsed time, the Commission shall have the power in cases of such emergency and it is hereby given authority to at once enter a temporary order, after notice to said public utility, fixing a temporary schedule of rates, which order shall be forthwith binding upon said public utility; provided, however, that the Commission's power to order reductions in rates and charges of any public utility by means of any such temporary order, is limited to reductions which will absorb not more than the amount found by the Commission to be in excess of the amount of income as determined by the Commission necessary to provide a reasonable return on the value of the property of said public utility as found by the Commission as aforesaid; and provided, further, however, that no such temporary order shall remain in force or effect for a longer period than 9 months from its effective date, and a further period not to exceed 3 months in addition if so ordered by the Commission; and provided, further, that if upon the final disposition of the issues involved in such proceeding, the rates or charges as finally determined by said Commission or the court having jurisdiction of the subject matter are in excess of the rates and charges prescribed in said temporary order, then and in such event such public utility shall be permitted over such reasonable time as the Commission shall fix, to amortize and recover by means of a temporary increase over and above the rates and charges finally determined, such sum as shall represent the difference between the gross income obtained from the rates and charges prescribed in said temporary reduction order and the gross income which would have obtained, during the period such temporary reduction order was in effect, based upon the same volume, from the rates and charges finally determined.
    (b) If the Commission enters upon a hearing concerning the propriety of any proposed rate or other charge, classification, contract, practice, rule or regulation pursuant to Section 9‑201, and if the Commission is of the opinion and so finds in said cause that a hearing to determine all of the issues involved in a final determination of rates or services will require more than 120 days of elapsed time, the Commission shall have the power to enter a temporary order fixing a temporary schedule of rates after hearing, which order shall be forthwith binding upon the public utility. As soon as practicable after the effective date of this amendatory Act of 1985, the Commission shall determine by rule the facts and circumstances which must be established by the utility in order to justify the grant of a temporary rate increase as provided herein. The Commission shall determine any temporary rate increase according to previously established standards until the time such rules become effective.
    In any case in which the Commission grants interim relief, the Commission shall, upon final disposition of the proposed permanent change in rates or other charges, classification, contract, practice, rule or regulation, also review the propriety of its prior award of interim relief based upon the criteria used by the Commission in granting the interim rate relief. If, upon such review, the Commission determines that such interim rates or charges were in excess of the rates or charges which should have been prescribed in its temporary order, the Commission shall require the public utility to refund such sum as shall represent the difference between the gross income obtained from the rates or charges prescribed in said temporary increase order and the gross income which would have been obtained during the period such temporary increase order was in effect based upon the same volume, from the rates and charges which the Commission upon final review determines were appropriate. Any refund shall include interest calculated at a rate determined by the Commission and shall be returned according to procedures prescribed by the Commission.

    (220 ILCS 5/9‑210) (from Ch. 111 2/3, par. 9‑210)
    Sec. 9‑210. The Commission shall have power to ascertain the value of the property of every public utility in this State and every fact which in its judgment may or does have any bearing on such value. In all proceedings before the Commission, initiated by the Commission upon its own motion, or initiated by an application of such public utility, in which the value of the property of any public utility or utilities is an issue, the burden of establishing such value shall be upon such public utility or utilities. In making such valuation the Commission may avail itself of any information, books, documents, or records in the possession of any officer, department or board of the State or any subdivision thereof. The Commission shall have power to make revaluation from time to time and also to ascertain the value of all new construction, extensions, and additions to the property of every public utility.
    For purposes of establishing the value of public utility property, when determining rates or charges, or for any other reason, the Commission may base its determination on the original cost of such property.

    (220 ILCS 5/9‑211) (from Ch. 111 2/3, par. 9‑211)
    Sec. 9‑211. The Commission, in any determination of rates or charges, shall include in a utility's rate base only the value of such investment which is both prudently incurred and used and useful in providing service to public utility customers.
(Source: P.A. 84‑617.)

    (220 ILCS 5/9‑212) (from Ch. 111 2/3, par. 9‑212)
    Sec. 9‑212. No new electric utility generating plant or gas production facility, or significant addition to existing facilities or plant, shall be included in a utility's rate base unless and until the utility proves, and the Commission determines, that such plant or facility is both prudent and used and useful in providing utility service to the utility's customers. For purposes of this Section, "prudent" means that at the time of certification, initiation of construction and each subsequent evaluation of any construction project until the time of completion, based on the evidence introduced in any hearings and all information which was known or should have been known at the time, and relevant planning and certification criteria, it was prudent and reasonable to conclude that the generating or production facility would be used and useful in providing service to customers at the time of completion. If the Commission has issued a certificate of public convenience and necessity for the completed facility, and to the extent that the Commission approves continued construction upon reevaluation subsequent to certification, such actions shall constitute prima facie evidence of the prudence of construction. If the Commission determines as a result of reevaluation during construction that the facility should not be completed, such determination shall constitute prima facie evidence that subsequent construction expenditures were imprudent.
    A generation or production facility is used and useful only if, and only to the extent that, it is necessary to meet customer demand or economically beneficial in meeting such demand. No generation or production facility shall be found used and useful until and unless it is capable of generation or production at significant operating levels on a consistent and sustainable basis. Any pollution control devices for the control of sulfur dioxide emissions installed or used in accordance with, and up to the cost specified in, an order or supplemental order of the Commission entered pursuant to subsection (e) of Section 8‑402.1 shall be deemed prudent and shall, upon being placed into operation on a consistent, sustainable basis by the public utility, be deemed used and useful.

    (220 ILCS 5/9‑213) (from Ch. 111 2/3, par. 9‑213)
    Sec. 9‑213. The cost of new electric utility generating plants and significant additions to electric utility generating plants shall not be included in the rate base of any utility unless such cost is reasonable. Prior to including the cost of plants or additions to utility plants in the rate base, the Commission shall conduct an audit of such costs in order to ascertain whether the cost associated with the new generating plant or the addition to electric utility generating plant is reasonable. However, the Commission may, for good cause shown in individual cases, waive the auditing requirement for any generating facility which meets all of the following requirements:
        (1) the facility is wholly owned and operated by a
     public utility, as otherwise defined in this Act, which serves less than 20,000 electric customers within the State of Illinois, and
        (2) the facility is designed to generate less than
     50 megawatts of electricity, and
        (3) the facility is located outside of the State of
     Illinois.
    If the Commission is unable to conduct such an audit, the Commission shall arrange for it to be conducted by persons independent of the utility and selected by the Commission. The cost of such an independent audit shall be borne initially by the utility, but shall be recovered as an expense through normal ratemaking procedures. Any such audits shall be conducted in accordance with generally accepted auditing standards and shall include but not be limited to costs associated with materials, labor, equipment, professional services and other direct and indirect costs.
    "Significant additions to the electric utility generating plant", as used in this Section, shall not include a public utility's investment in pollution control devices for the control of sulfur dioxide emissions. Nothing in this Section is intended to affect the provisions of Section 9‑214 of this Act.
    "Reasonable", as used in this Section, means that a utility's decisions, construction, and supervision of construction, underlying the costs of new electric utility generating plants and significant additions to electric utility generating plants resulted in efficient, economical and timely construction. In determining the reasonableness of plant costs, the Commission shall consider the knowledge and circumstances prevailing at the time of each relevant utility decision or action.
    Nothing in this Section shall prevent or limit the Commission from either entering into and conducting joint audits concerning such electric generating plants with the regulatory authority of another state, or from relying on audits conducted by the regulatory authority of another state in lieu of an audit as required by this Section.

    Sec. 9‑214. (a) As used in this Section:
        (1) "CWIP" means those assets which are recorded as
     construction work in progress on a public utility's books of accounts maintained in accordance with the applicable regulations and orders of the Commission.
        (2) "Rate base" means the original cost value of the
     property on which a return is allowed.
        (3) "CWIP ratio" means the fraction, expressed as a
     percentage, calculated by dividing the amount of CWIP included in a public utility's rate base by the utility's rate base.
        (4) "Existing CWIP" means the amount of CWIP
     included in the rate base on December 1, 1983.
    (b) In any determination under Section 9‑201, 9‑202 or 9‑250 of this Act in a proceeding begun on or after December 1, 1983:
        (1) For any public utility with a CWIP ratio on
     December 1, 1983, which is less than 15%, the Commission shall not include in the rate base for such public utility an amount for CWIP to exceed 80% of existing CWIP for the period from December 1, 1983 through December 31, 1984, and 60% of existing CWIP for the period from January 1, 1985 through December 31, 1985 and 40% of existing CWIP for the period from January 1, 1986 through December 31, 1986, and 20% of existing CWIP for the period from January 1, 1987 through December 31, 1987.
        (2) For any public utility with a CWIP ratio on
     December 1, 1983 which is greater than or equal to 15%, the Commission shall not include in the rate base for such public utility an amount for CWIP in excess of the amount of CWIP included in the rate base on December 1, 1983, plus 50% of the allowed construction expenses incurred by the public utility from the date of the most recent rate determination by the Commission prior to December 1, 1983.
    (c) The limitations set forth in paragraph (b) of this Section shall not be interpreted as an expansion of the Commission's authority to include CWIP in the rate base, but rather solely as a limitation thereon.
    (d) The Commission shall not include an amount for CWIP in the rate base for any public utility for the period after December 31, 1988.
    (e) Notwithstanding the provisions of paragraphs (b) and (d) of this Section the Commission may include in the rate base of a public utility an amount for CWIP for a public utility's investment which is scheduled to be placed in service within 12 months of the date of the rate determination. For the purposes of this paragraph nuclear generating facilities shall be considered to be in service upon the commencement of electric generation.
    (f) Notwithstanding the provisions of paragraph (b) and (d), the Commission may include in the rate base of a public utility an amount of CWIP for a public utility's investment in pollution control devices for the control of sulfur dioxide emissions and the purification of water and sewage; provided, however, that upon application by a public utility which is constructing one or more pollution control devices for the control of sulfur dioxide emissions as part of a Clean Air Act compliance plan approved by the Commission pursuant to subsection (e) of Section 8‑402.1, the Commission shall include in such public utility's rate base an amount of CWIP equal to its investment in such pollution control device or devices, but not to exceed the estimated cost of such facilities specified in the Commission's order or supplemental order pursuant to subsection (e) of Section 8‑402.1. For purposes of this subsection (f), the public utility's investment shall not include the amount of any state, federal or other grants provided to the public utility to fund the design, acquisition, construction, installation and testing of pollution control devices for the control of sulfur dioxide emissions.
    (g) Except for those amounts of CWIP described in paragraphs (e) and (f) of this Section, the Commission shall consider, in any rate filing subsequent to the coming on line of any new utility plant where CWIP funds have been allowed in rate base, a rate moderation plan directed towards allowing an appropriate return to ratepayers for previous amounts attributable to CWIP funds.
    The Commission shall conduct an investigation and study of the costs and benefits to ratepayers of the inclusion of construction work in progress in rate base. Such study shall include a full opportunity for participation by the public through notice and hearings. If the Commission determines that in certain circumstances the inclusion of CWIP in rate base would be demonstrably beneficial to ratepayers, the Commission shall report its findings with recommendations to the General Assembly by December 31, 1988.

ARTICLE IX. RATES

    (220 ILCS 5/9‑101) (from Ch. 111 2/3, par. 9‑101)
    Sec. 9‑101. All rates or other charges made, demanded or received by any product or commodity furnished or to be furnished or for any service rendered or to be rendered shall be just and reasonable. Every unjust or unreasonable charge made, demanded or received for such product or commodity or service is hereby prohibited and declared unlawful. All rules and regulations made by a public utility affecting or pertaining to its charges to the public shall be just and reasonable.

    (220 ILCS 5/9‑102) (from Ch. 111 2/3, par. 9‑102)
    Sec. 9‑102. Every public utility shall file with the Commission and shall print and keep open to public inspection schedules showing all rates and other charges, and classifications, which are in force at the time for any product or commodity furnished or to be furnished by it, or for any service performed by it, or for any service in connection therewith, or performed by any public utility controlled or operated by it. Every public utility shall file with and as a part of such schedule and shall state separately all rules, regulations, storage or other charges, privileges and contracts that in any manner affect the rates charged or to be charged for any service. Such schedule shall be filed for all services performed wholly or partly within this State, and the rates and other charges and classifications shall not, without the consent of the Commission, exceed those in effect on December 31, 1985. But nothing in this section shall prevent the Commission from approving or fixing rates or other charges or classifications from time to time, in excess of or less than those shown by said schedules.
    Where a schedule of joint rates or other charges, or classifications is or may be in force between two or more public utilities such schedules shall in like manner be printed and filed with the Commission, and so much thereof as the Commission shall deem necessary for the use of the public shall be filed in every office of such public utility in accordance with the terms of Section 9‑103 of this Act. Unless otherwise ordered by the Commission a schedule showing such joint rates or other charges, or classifications need not be filed with the Commission by more than one of the parties to it: Provided, that there is also filed with the Commission a concurrence in such schedule by each of the other parties thereto.
    Every public utility shall file with the Commission copies of all contracts, agreements or arrangements with other public utilities, in relation to any service, product or commodity affected by the provisions of this Act, to which it may be a party, and copies of all other contracts, agreements or arrangements with any other person or corporation affecting in the judgment of the Commission the cost to such public utility of any service, product or commodity.

    (220 ILCS 5/9‑102.1)
    Sec. 9‑102.1. Negotiated rates.
    (a) Notwithstanding anything to the contrary in any other Section of Article IX of this Act, the Commission may approve one or more rate schedules filed by a public utility that enable the public utility to provide service to customers under contracts that are treated as proprietary and confidential by the Commission notwithstanding the filing thereof. Service under the contracts shall be provided on such terms and for such rates or charges as the public utility and the customer agree upon, without regard to any rate schedules the public utility may have filed with the Commission under any other Section of Article IX of this Act. The contracts shall be filed with the Commission, notwithstanding anything to the contrary in any schedule referred to in subsection (b) of this Section. For purposes of Section 3‑121 of this Act, the amounts collected under the contracts shall be treated as having been collected under rates that the public utility is required to file under Section 9‑102 of this Act.
    (b) Each schedule described in subsection (a) that became effective before August 25, 1995, and any contract thereunder, shall be deemed to have become effective in accordance with its terms, subject to the provisions of any Commission order that purported to authorize the schedule.
    (c) In any determination of the rates to be charged by an electric public utility having contracts in effect pursuant to schedules filed under this Section or schedules referred to in subsection (b) of this Section, the revenues received, or to be received, by the electric public utility under each such contract shall be deemed to be equal to the revenues, based on the actual usage of the customer, that would have been, or would be, received under the lowest rates available under schedules on file pursuant to Section 9‑201, applicable to a class of consumers that includes the customer, including any applicable riders or surcharges, plus any revenues that would have been, or would be required to pay for investment or expenses incurred by the electric public utility that would not be incurred if service were provided under such lowest rates. The cost of capital used to determine rates to be charged by the electric public utility shall be that which would have obtained if service were provided under such lowest rates. The provisions of this subsection (c) shall not apply: (1) in any determination of the rates to be charged by a gas public utility, and (2) in any determination of the rates to be charged by an electric public utility, to contracts in effect prior to the effective date of this amendatory Act of 1996 pursuant to economic development schedules referred to in Section 9‑241 of this Act, under which the electric public utility is authorized to provide discounts for new electrical sales that result from the location of new or expanded industrial facilities in the electric public utility's service territory. The preceding sentence shall not be construed to diminish the Commission's existing authority as of the effective date of this amendatory Act of 1996 to allocate the costs of all public utilities equitably, in any determination of rates, so as to set rates which are just and reasonable.
    (d) Any contract filed pursuant to the provisions of subsection (a) of this Section shall be accorded proprietary and confidential treatment by the Commission and otherwise deemed to be exempt from the requirements of Sections 9‑102, 9‑103, 9‑104, 9‑201, 9‑240, 9‑241, and 9‑243, except to the extent the Commission may, in its discretion, order otherwise. The Commission shall permit any statutory consumer protection agency to have access to any such contract, provided that: (i) the agency, and each individual that will have access on behalf of the agency, agree in writing to keep such contract confidential, such agreement to be in a form established by the Commission; and (ii) access is limited to full‑time employees of the agency and such other persons as are acceptable to the public utility or, if the agency and the public utility are unable to agree, are determined to be acceptable by the Commission. "Statutory consumer protection agency" means any office, corporation, or other agency created by Article XI of this Act or any other Illinois statute as of the effective date of this amendatory Act of 1996 that has an express statutory duty to represent the interest of public utility customers, any such agency subsequently created by act of the General Assembly that expressly authorizes the agency to access the information described in this subsection, or the Attorney General of the State of Illinois.
    (e) Nothing in this Section shall be construed to give a public utility the authority to provide electric or natural gas service to a customer the public utility is not otherwise lawfully entitled to serve. Nothing in this Section shall be construed to affect in any way the service rights of electric suppliers as granted under the Electric Supplier Act.
    (f) The provisions of subsection (b) of this Section 9‑102.1 are intended to be severable from the remaining provisions of this Act; and therefore, no determination of the validity of the provisions of subsection (b) shall affect the validity of the remaining provisions of this Section 9‑102.1.
    (g) After January 1, 2001, no contract for electric service may be entered into under any schedule filed pursuant to the provisions of subsection (a) of this Section or under any schedule referred to in subsection (b) of this Section. The foregoing provision shall not affect any contract entered into prior to January 1, 2001.
    (h) Nothing contained in this Section shall be construed as preventing any customer or other appropriate party from filing a complaint or otherwise requesting that the Commission investigate the reasonableness of the terms and conditions of any schedule filed under this Section or referred to in subsection (b) of this Section. Nothing contained in this Section shall be construed as affecting the right of any customer or public utility to enter into and enforce any contract providing for the amounts to be charged for service where the contract is or has been filed pursuant to any other Section of this Act. Nothing contained in this Section shall be construed to limit any Commission authority to authorize a public utility to engage in experimental programs relating to competition, including direct access programs.

    Sec. 9‑103. Posting of rate schedules. Subject to such rules and regulations as the Commission may prescribe, the schedules referred to in Section 9‑102 shall be posted or kept on file in every office of a public utility where the public transacts business with such public utility. Any or all of such schedules kept as aforesaid shall be immediately produced by such public utility for inspection upon the demand of any person. A notice printed in bold type, in size prescribed by the Commission, stating that such schedules are on file with the agent and open to inspection by any person, and that the agent will assist any person to determine from such schedules any rates or other charges, classification, rules or regulations in force, shall be kept posted by the public utility in two public and conspicuous places in every such office. The form of every such schedule shall be prescribed by the Commission: Provided, that in lieu of filing the entire schedule in each office, any public utility may, subject to the regulations of the Commission, file or keep posted at such office, schedules of such rates or other charges, classifications, rules and regulations relating thereto, as are applicable at, to and from the place where such office is located.
    The Commission may determine and prescribe the form in which the schedules required by this Act to be filed with the Commission and to be kept open to public inspection shall be prepared and arranged, and may change the form from time to time if it shall be found expedient.

No public utility shall undertake to perform any service or to furnish any product or commodity unless or until the rates and other charges and classifications, rules and regulations relating thereto, applicable to such service, product or commodity, have been filed and published in accordance with the provisions of this Act: Provided, that in cases of emergency, a service, product or commodity not specifically covered by the schedules filed, may be performed or furnished at a reasonable rate, which rate shall forthwith be filed and shall be subject to review in accordance with the provisions of this Act.

    (220 ILCS 5/9‑201)(from Ch. 111 2/3, par. 9‑201)
    Sec. 9‑201. (a) Unless the Commission otherwise orders, and except as otherwise provided in this Section, no change shall be made by any public utility in any rate or other charge or classification, or in any rule, regulation, practice or contract relating to or affecting any rate or other charge, classification or service, or in any privilege or facility, except after 45 days' notice to the Commission and to the public as herein provided. Such notice shall be given by filing with the Commission and keeping open for public inspection new schedules or supplements stating plainly the change or changes to be made in the schedule or schedules then in force, and the time when the change or changes will go into effect, and by publication in a newspaper of general circulation or such other notice to persons affected by such change as may be prescribed by rule of the Commission. The Commission, for good cause shown, may allow changes without requiring the 45 days' notice herein provided for, by an order specifying the changes so to be made and the time when they shall take effect and the manner in which they shall be filed and published.
    When any change is proposed in any rate or other charge, or classification, or in any rule, regulation, practice, or contract relating to or affecting any rate or other charge, classification or service, or in any privilege or facility, such proposed change shall be plainly indicated on the new schedule filed with the Commission, by some character to be designated by the Commission, immediately preceding or following the item.
    When any public utility providing water or sewer service proposes any change in any rate or other charge, or classification, or in any rule, regulation, practice, or contract relating to or affecting any rate or other charge, classification or service, or in any privilege or facility, such utility shall, in addition to the other notice requirements of this Act, provide notice of such change to all customers potentially affected by including a notice and description of such change, and of Commission procedures for intervention, in the first bill sent to each such customer after the filing of the proposed change.
    (b) Whenever there shall be filed with the Commission any schedule stating an individual or joint rate or other charge, classification, contract, practice, rule or regulation, the Commission shall have power, and it is hereby given authority, either upon complaint or upon its own initiative without complaint, at once, and if it so orders, without answer or other formal pleadings by the interested public utility or utilities, but upon reasonable notice, to enter upon a hearing concerning the propriety of such rate or other charge, classification, contract, practice, rule or regulation, and pending the hearing and decision thereon, such rate or other charge, classification, contract, practice, rule or regulation shall not go into effect. The period of suspension of such rate or other charge, classification, contract, practice, rule or regulation shall not extend more than 105 days beyond the time when such rate or other charge, classification, contract, practice, rule or regulation would otherwise go into effect unless the Commission, in its discretion, extends the period of suspension for a further period not exceeding 6 months.
    All rates or other charges, classifications, contracts, practices, rules or regulations not so suspended shall, on the expiration of 45 days from the time of filing the same with the Commission, or of such lesser time as the Commission may grant, go into effect and be the established and effective rates or other charges, classifications, contracts, practices, rules and regulations, subject to the power of the Commission, after a hearing had on its own motion or upon complaint, as herein provided, to alter or modify the same.
    Within 30 days after such changes have been authorized by the Commission, copies of the new or revised schedules shall be posted or filed in accordance with the terms of Section 9‑103 of this Act, in such a manner that all changes shall be plainly indicated. The Commission shall incorporate into the period of suspension a review period of 4 business days during which the Commission may review and determine whether the new or revised schedules comply with the Commission's decision approving a change to the public utility's rates. Such review period shall not extend the suspension period by more than 2 days. Absent notification to the contrary within the 4 business day period, the new or revised schedules shall be deemed approved.
    (c) If the Commission enters upon a hearing concerning the propriety of any proposed rate or other charge, classification, contract, practice, rule or regulation, the Commission shall establish the rates or other charges, classifications, contracts, practices, rules or regulations proposed, in whole or in part, or others in lieu thereof, which it shall find to be just and reasonable. In such hearing, the burden of proof to establish the justness and reasonableness of the proposed rates or other charges, classifications, contracts, practices, rules or regulations, in whole and in part, shall be upon the utility. The utility, the staff of the Commission, the Attorney General, or any party to a proceeding initiated under this Section who has been granted intervenor status and submitted a post‑hearing brief must be given the opportunity to present oral argument, if requested no later than the date for filing exceptions, on the propriety of any proposed rate or other charge, classification, contract, practice, rule, or regulation. No rate or other charge, classification, contract, practice, rule or regulation shall be found just and reasonable unless it is consistent with Sections of this Article.
    (d) Except where compliance with Section 8‑401 of this Act is of urgent and immediate concern, no representative of a public utility may discuss with a commissioner, commissioner's assistant, or hearing examiner in a non‑public setting a planned filing for a general rate increase. If a public utility makes a filing under this Section, then no substantive communication by any such person with a commissioner, commissioner's assistant or hearing examiner concerning the filing is permitted until a notice of hearing has been issued. After the notice of hearing has been issued, the only communications by any such person with a commissioner, commissioner's assistant, or hearing examiner concerning the filing permitted are communications permitted under Section 10‑103 of this Act. If any such communication does occur, then within 5 days of the docket being initiated all details relating to the communication shall be placed on the public record of the proceeding. The record shall include any materials, whether written, recorded, filmed, or graphic in nature, produced or reproduced on any media, used in connection with the communication. The record shall reflect the names of all persons who transmitted, received, or were otherwise involved in the communication, the duration of the communication, and whether the communication occurred in person or by other means. In the case of an oral communication, the record shall also reflect the location or locations of all persons involved in the communication and, if the communication occurred by telephone, the telephone numbers for the callers and recipients of the communication. A commissioner, commissioner's assistant, or hearing examiner who is involved in any such communication shall be recused from the affected proceeding. The Commission, or any commissioner or hearing examiner presiding over the proceeding shall, in the event of a violation of this Section, take action necessary to ensure that such violation does not prejudice any party or adversely affect the fairness of the proceedings including dismissing the affected proceeding. Nothing in this subsection (d) is intended to preclude otherwise allowable updates on issues that may be indirectly related to a general rate case filing because cost recovery for the underlying activity may be requested. Such updates may include, without limitation, issues related to outages and restoration, credit ratings, security issuances, reliability, Federal Energy Regulatory Commission matters, Federal Communications Commission matters, regional reliability organizations, consumer education, or labor matters, provided that such updates may not include cost recovery in a planned rate case.

    (220 ILCS 5/9‑201.5)
    Sec. 9‑201.5. Decommissioning nuclear power plants; rates.
    (a) The Commission may after hearing, in a rate case or otherwise, authorize the institution of rate provisions or tariffs that increase or decrease charges to customers to reflect changes in, or additional or reduced costs of, decommissioning nuclear power plants, including accruals for estimates of those costs, irrespective of any changes in other costs or revenues; provided the revenues collected under such rates or tariffs are used to recover costs associated with contributions to appropriate decommissioning trust funds or to reduce the amounts to be charged under such rates or tariffs in the future. These provisions or tariffs shall hereinafter be referred to as "decommissioning rates".
    (b) A public utility that does not have a decommissioning rate in effect on the effective date of this amendatory Act of 1994 may not place a decommissioning rate in effect before January 1, 1995. Changes in charges under a decommissioning rate shall not be subject to the notice and filing requirements of subsection (a) of Section 9‑201 of this Act, but a decommissioning rate of a utility that does not have such a rate in effect before the effective date of this amendatory Act of 1994 shall provide that no increase in charges under that rate may take effect until 60 days after the utility provides the proposed increased charge to the Commission for review. The Commission may require that a decommissioning rate contain provisions for reconciling amounts collected under the rate with both reasonably projected costs and actual costs prudently incurred. As used in this Section, "decommissioning costs" and "decommissioning trust fund" have the same meaning as in Section 8‑508.1 of this Act.
    (c) Nothing contained in this amendatory Act of 1994 shall affect any determination of the authority of the Commission before the effective date of this amendatory Act of 1994. Nothing contained in this amendatory Act of 1994 shall be used in any determination of the authority of the Commission after the effective date of this amendatory Act of 1994, except with respect to decommissioning rates.
    (d) A decommissioning rate authorized by the Commission under this Section and the decommissioning cost studies underlying the rate shall be subject to hearing and review, in a rate case or otherwise, not less than once every 6 years.

    (220 ILCS 5/9‑202) (from Ch. 111 2/3, par. 9‑202)
    Sec. 9‑202. (a) Whenever the Commission is of the opinion and so finds after an examination of any report or reports, annual or otherwise, filed with the Commission by any public utility, together with any other facts or information which the Commission may acquire or receive from an investigation of the books, records or papers or from an inspection of the property of such public utility, that the net income of such public utility after reasonable deductions for depreciation and other proper and necessary reserves, is in excess of the amount required for a reasonable return upon the value of said public utility's property used and useful in rendering its service to the public, provided however that in computing net income, deductions shall not be made for advertising expenses as prohibited under Section 9‑225 of this Act, and if the Commission is of the opinion and so finds in said cause that a hearing to determine all of the issues involved in a final determination of rates or services will require more than 105 days of elapsed time, the Commission shall have the power in cases of such emergency and it is hereby given authority to at once enter a temporary order, after notice to said public utility, fixing a temporary schedule of rates, which order shall be forthwith binding upon said public utility; provided, however, that the Commission's power to order reductions in rates and charges of any public utility by means of any such temporary order, is limited to reductions which will absorb not more than the amount found by the Commission to be in excess of the amount of income as determined by the Commission necessary to provide a reasonable return on the value of the property of said public utility as found by the Commission as aforesaid; and provided, further, however, that no such temporary order shall remain in force or effect for a longer period than 9 months from its effective date, and a further period not to exceed 3 months in addition if so ordered by the Commission; and provided, further, that if upon the final disposition of the issues involved in such proceeding, the rates or charges as finally determined by said Commission or the court having jurisdiction of the subject matter are in excess of the rates and charges prescribed in said temporary order, then and in such event such public utility shall be permitted over such reasonable time as the Commission shall fix, to amortize and recover by means of a temporary increase over and above the rates and charges finally determined, such sum as shall represent the difference between the gross income obtained from the rates and charges prescribed in said temporary reduction order and the gross income which would have obtained, during the period such temporary reduction order was in effect, based upon the same volume, from the rates and charges finally determined.
    (b) If the Commission enters upon a hearing concerning the propriety of any proposed rate or other charge, classification, contract, practice, rule or regulation pursuant to Section 9‑201, and if the Commission is of the opinion and so finds in said cause that a hearing to determine all of the issues involved in a final determination of rates or services will require more than 120 days of elapsed time, the Commission shall have the power to enter a temporary order fixing a temporary schedule of rates after hearing, which order shall be forthwith binding upon the public utility. As soon as practicable after the effective date of this amendatory Act of 1985, the Commission shall determine by rule the facts and circumstances which must be established by the utility in order to justify the grant of a temporary rate increase as provided herein. The Commission shall determine any temporary rate increase according to previously established standards until the time such rules become effective.
    In any case in which the Commission grants interim relief, the Commission shall, upon final disposition of the proposed permanent change in rates or other charges, classification, contract, practice, rule or regulation, also review the propriety of its prior award of interim relief based upon the criteria used by the Commission in granting the interim rate relief. If, upon such review, the Commission determines that such interim rates or charges were in excess of the rates or charges which should have been prescribed in its temporary order, the Commission shall require the public utility to refund such sum as shall represent the difference between the gross income obtained from the rates or charges prescribed in said temporary increase order and the gross income which would have been obtained during the period such temporary increase order was in effect based upon the same volume, from the rates and charges which the Commission upon final review determines were appropriate. Any refund shall include interest calculated at a rate determined by the Commission and shall be returned according to procedures prescribed by the Commission.

    Sec. 9‑210. The Commission shall have power to ascertain the value of the property of every public utility in this State and every fact which in its judgment may or does have any bearing on such value. In all proceedings before the Commission, initiated by the Commission upon its own motion, or initiated by an application of such public utility, in which the value of the property of any public utility or utilities is an issue, the burden of establishing such value shall be upon such public utility or utilities. In making such valuation the Commission may avail itself of any information, books, documents, or records in the possession of any officer, department or board of the State or any subdivision thereof. The Commission shall have power to make revaluation from time to time and also to ascertain the value of all new construction, extensions, and additions to the property of every public utility.
    For purposes of establishing the value of public utility property, when determining rates or charges, or for any other reason, the Commission may base its determination on the original cost of such property.

    (220 ILCS 5/9‑212) (from Ch. 111 2/3, par. 9‑212)
    Sec. 9‑212. No new electric utility generating plant or gas production facility, or significant addition to existing facilities or plant, shall be included in a utility's rate base unless and until the utility proves, and the Commission determines, that such plant or facility is both prudent and used and useful in providing utility service to the utility's customers. For purposes of this Section, "prudent" means that at the time of certification, initiation of construction and each subsequent evaluation of any construction project until the time of completion, based on the evidence introduced in any hearings and all information which was known or should have been known at the time, and relevant planning and certification criteria, it was prudent and reasonable to conclude that the generating or production facility would be used and useful in providing service to customers at the time of completion. If the Commission has issued a certificate of public convenience and necessity for the completed facility, and to the extent that the Commission approves continued construction upon reevaluation subsequent to certification, such actions shall constitute prima facie evidence of the prudence of construction. If the Commission determines as a result of reevaluation during construction that the facility should not be completed, such determination shall constitute prima facie evidence that subsequent construction expenditures were imprudent.
    A generation or production facility is used and useful only if, and only to the extent that, it is necessary to meet customer demand or economically beneficial in meeting such demand. No generation or production facility shall be found used and useful until and unless it is capable of generation or production at significant operating levels on a consistent and sustainable basis. Any pollution control devices for the control of sulfur dioxide emissions installed or used in accordance with, and up to the cost specified in, an order or supplemental order of the Commission entered pursuant to subsection (e) of Section 8‑402.1 shall be deemed prudent and shall, upon being placed into operation on a consistent, sustainable basis by the public utility, be deemed used and useful.

    (220 ILCS 5/9‑213) (from Ch. 111 2/3, par. 9‑213)
    Sec. 9‑213. The cost of new electric utility generating plants and significant additions to electric utility generating plants shall not be included in the rate base of any utility unless such cost is reasonable. Prior to including the cost of plants or additions to utility plants in the rate base, the Commission shall conduct an audit of such costs in order to ascertain whether the cost associated with the new generating plant or the addition to electric utility generating plant is reasonable. However, the Commission may, for good cause shown in individual cases, waive the auditing requirement for any generating facility which meets all of the following requirements:
        (1) the facility is wholly owned and operated by a
     public utility, as otherwise defined in this Act, which serves less than 20,000 electric customers within the State of Illinois, and
        (2) the facility is designed to generate less than
     50 megawatts of electricity, and
        (3) the facility is located outside of the State of
     Illinois.
    If the Commission is unable to conduct such an audit, the Commission shall arrange for it to be conducted by persons independent of the utility and selected by the Commission. The cost of such an independent audit shall be borne initially by the utility, but shall be recovered as an expense through normal ratemaking procedures. Any such audits shall be conducted in accordance with generally accepted auditing standards and shall include but not be limited to costs associated with materials, labor, equipment, professional services and other direct and indirect costs.
    "Significant additions to the electric utility generating plant", as used in this Section, shall not include a public utility's investment in pollution control devices for the control of sulfur dioxide emissions. Nothing in this Section is intended to affect the provisions of Section 9‑214 of this Act.
    "Reasonable", as used in this Section, means that a utility's decisions, construction, and supervision of construction, underlying the costs of new electric utility generating plants and significant additions to electric utility generating plants resulted in efficient, economical and timely construction. In determining the reasonableness of plant costs, the Commission shall consider the knowledge and circumstances prevailing at the time of each relevant utility decision or action.
    Nothing in this Section shall prevent or limit the Commission from either entering into and conducting joint audits concerning such electric generating plants with the regulatory authority of another state, or from relying on audits conducted by the regulatory authority of another state in lieu of an audit as required by this Section.

    (220 ILCS 5/9‑214) (from Ch. 111 2/3, par. 9‑214)
    Sec. 9‑214. (a) As used in this Section:
        (1) "CWIP" means those assets which are recorded as
     construction work in progress on a public utility's books of accounts maintained in accordance with the applicable regulations and orders of the Commission.
        (2) "Rate base" means the original cost value of the
     property on which a return is allowed.
        (3) "CWIP ratio" means the fraction, expressed as a
     percentage, calculated by dividing the amount of CWIP included in a public utility's rate base by the utility's rate base.
        (4) "Existing CWIP" means the amount of CWIP
     included in the rate base on December 1, 1983.
    (b) In any determination under Section 9‑201, 9‑202 or 9‑250 of this Act in a proceeding begun on or after December 1, 1983:
        (1) For any public utility with a CWIP ratio on
     December 1, 1983, which is less than 15%, the Commission shall not include in the rate base for such public utility an amount for CWIP to exceed 80% of existing CWIP for the period from December 1, 1983 through December 31, 1984, and 60% of existing CWIP for the period from January 1, 1985 through December 31, 1985 and 40% of existing CWIP for the period from January 1, 1986 through December 31, 1986, and 20% of existing CWIP for the period from January 1, 1987 through December 31, 1987.
        (2) For any public utility with a CWIP ratio on
     December 1, 1983 which is greater than or equal to 15%, the Commission shall not include in the rate base for such public utility an amount for CWIP in excess of the amount of CWIP included in the rate base on December 1, 1983, plus 50% of the allowed construction expenses incurred by the public utility from the date of the most recent rate determination by the Commission prior to December 1, 1983.
    (c) The limitations set forth in paragraph (b) of this Section shall not be interpreted as an expansion of the Commission's authority to include CWIP in the rate base, but rather solely as a limitation thereon.
    (d) The Commission shall not include an amount for CWIP in the rate base for any public utility for the period after December 31, 1988.
    (e) Notwithstanding the provisions of paragraphs (b) and (d) of this Section the Commission may include in the rate base of a public utility an amount for CWIP for a public utility's investment which is scheduled to be placed in service within 12 months of the date of the rate determination. For the purposes of this paragraph nuclear generating facilities shall be considered to be in service upon the commencement of electric generation.
    (f) Notwithstanding the provisions of paragraph (b) and (d), the Commission may include in the rate base of a public utility an amount of CWIP for a public utility's investment in pollution control devices for the control of sulfur dioxide emissions and the purification of water and sewage; provided, however, that upon application by a public utility which is constructing one or more pollution control devices for the control of sulfur dioxide emissions as part of a Clean Air Act compliance plan approved by the Commission pursuant to subsection (e) of Section 8‑402.1, the Commission shall include in such public utility's rate base an amount of CWIP equal to its investment in such pollution control device or devices, but not to exceed the estimated cost of such facilities specified in the Commission's order or supplemental order pursuant to subsection (e) of Section 8‑402.1. For purposes of this subsection (f), the public utility's investment shall not include the amount of any state, federal or other grants provided to the public utility to fund the design, acquisition, construction, installation and testing of pollution control devices for the control of sulfur dioxide emissions.
    (g) Except for those amounts of CWIP described in paragraphs (e) and (f) of this Section, the Commission shall consider, in any rate filing subsequent to the coming on line of any new utility plant where CWIP funds have been allowed in rate base, a rate moderation plan directed towards allowing an appropriate return to ratepayers for previous amounts attributable to CWIP funds.
    The Commission shall conduct an investigation and study of the costs and benefits to ratepayers of the inclusion of construction work in progress in rate base. Such study shall include a full opportunity for participation by the public through notice and hearings. If the Commission determines that in certain circumstances the inclusion of CWIP in rate base would be demonstrably beneficial to ratepayers, the Commission shall report its findings with recommendations to the General Assembly by December 31, 1988.

ARTICLE IX. RATES

    (220 ILCS 5/9‑101) (from Ch. 111 2/3, par. 9‑101)
    Sec. 9‑101. All rates or other charges made, demanded or received by any product or commodity furnished or to be furnished or for any service rendered or to be rendered shall be just and reasonable. Every unjust or unreasonable charge made, demanded or received for such product or commodity or service is hereby prohibited and declared unlawful. All rules and regulations made by a public utility affecting or pertaining to its charges to the public shall be just and reasonable.
(Source: P.A. 84‑617.)

    (220 ILCS 5/9‑102) (from Ch. 111 2/3, par. 9‑102)
    Sec. 9‑102. Every public utility shall file with the Commission and shall print and keep open to public inspection schedules showing all rates and other charges, and classifications, which are in force at the time for any product or commodity furnished or to be furnished by it, or for any service performed by it, or for any service in connection therewith, or performed by any public utility controlled or operated by it. Every public utility shall file with and as a part of such schedule and shall state separately all rules, regulations, storage or other charges, privileges and contracts that in any manner affect the rates charged or to be charged for any service. Such schedule shall be filed for all services performed wholly or partly within this State, and the rates and other charges and classifications shall not, without the consent of the Commission, exceed those in effect on December 31, 1985. But nothing in this section shall prevent the Commission from approving or fixing rates or other charges or classifications from time to time, in excess of or less than those shown by said schedules.
    Where a schedule of joint rates or other charges, or classifications is or may be in force between two or more public utilities such schedules shall in like manner be printed and filed with the Commission, and so much thereof as the Commission shall deem necessary for the use of the public shall be filed in every office of such public utility in accordance with the terms of Section 9‑103 of this Act. Unless otherwise ordered by the Commission a schedule showing such joint rates or other charges, or classifications need not be filed with the Commission by more than one of the parties to it: Provided, that there is also filed with the Commission a concurrence in such schedule by each of the other parties thereto.
    Every public utility shall file with the Commission copies of all contracts, agreements or arrangements with other public utilities, in relation to any service, product or commodity affected by the provisions of this Act, to which it may be a party, and copies of all other contracts, agreements or arrangements with any other person or corporation affecting in the judgment of the Commission the cost to such public utility of any service, product or commodity.

    (220 ILCS 5/9‑102.1)
    Sec. 9‑102.1. Negotiated rates.
    (a) Notwithstanding anything to the contrary in any other Section of Article IX of this Act, the Commission may approve one or more rate schedules filed by a public utility that enable the public utility to provide service to customers under contracts that are treated as proprietary and confidential by the Commission notwithstanding the filing thereof. Service under the contracts shall be provided on such terms and for such rates or charges as the public utility and the customer agree upon, without regard to any rate schedules the public utility may have filed with the Commission under any other Section of Article IX of this Act. The contracts shall be filed with the Commission, notwithstanding anything to the contrary in any schedule referred to in subsection (b) of this Section. For purposes of Section 3‑121 of this Act, the amounts collected under the contracts shall be treated as having been collected under rates that the public utility is required to file under Section 9‑102 of this Act.
    (b) Each schedule described in subsection (a) that became effective before August 25, 1995, and any contract thereunder, shall be deemed to have become effective in accordance with its terms, subject to the provisions of any Commission order that purported to authorize the schedule.
    (c) In any determination of the rates to be charged by an electric public utility having contracts in effect pursuant to schedules filed under this Section or schedules referred to in subsection (b) of this Section, the revenues received, or to be received, by the electric public utility under each such contract shall be deemed to be equal to the revenues, based on the actual usage of the customer, that would have been, or would be, received under the lowest rates available under schedules on file pursuant to Section 9‑201, applicable to a class of consumers that includes the customer, including any applicable riders or surcharges, plus any revenues that would have been, or would be required to pay for investment or expenses incurred by the electric public utility that would not be incurred if service were provided under such lowest rates. The cost of capital used to determine rates to be charged by the electric public utility shall be that which would have obtained if service were provided under such lowest rates. The provisions of this subsection (c) shall not apply: (1) in any determination of the rates to be charged by a gas public utility, and (2) in any determination of the rates to be charged by an electric public utility, to contracts in effect prior to the effective date of this amendatory Act of 1996 pursuant to economic development schedules referred to in Section 9‑241 of this Act, under which the electric public utility is authorized to provide discounts for new electrical sales that result from the location of new or expanded industrial facilities in the electric public utility's service territory. The preceding sentence shall not be construed to diminish the Commission's existing authority as of the effective date of this amendatory Act of 1996 to allocate the costs of all public utilities equitably, in any determination of rates, so as to set rates which are just and reasonable.
    (d) Any contract filed pursuant to the provisions of subsection (a) of this Section shall be accorded proprietary and confidential treatment by the Commission and otherwise deemed to be exempt from the requirements of Sections 9‑102, 9‑103, 9‑104, 9‑201, 9‑240, 9‑241, and 9‑243, except to the extent the Commission may, in its discretion, order otherwise. The Commission shall permit any statutory consumer protection agency to have access to any such contract, provided that: (i) the agency, and each individual that will have access on behalf of the agency, agree in writing to keep such contract confidential, such agreement to be in a form established by the Commission; and (ii) access is limited to full‑time employees of the agency and such other persons as are acceptable to the public utility or, if the agency and the public utility are unable to agree, are determined to be acceptable by the Commission. "Statutory consumer protection agency" means any office, corporation, or other agency created by Article XI of this Act or any other Illinois statute as of the effective date of this amendatory Act of 1996 that has an express statutory duty to represent the interest of public utility customers, any such agency subsequently created by act of the General Assembly that expressly authorizes the agency to access the information described in this subsection, or the Attorney General of the State of Illinois.
    (e) Nothing in this Section shall be construed to give a public utility the authority to provide electric or natural gas service to a customer the public utility is not otherwise lawfully entitled to serve. Nothing in this Section shall be construed to affect in any way the service rights of electric suppliers as granted under the Electric Supplier Act.
    (f) The provisions of subsection (b) of this Section 9‑102.1 are intended to be severable from the remaining provisions of this Act; and therefore, no determination of the validity of the provisions of subsection (b) shall affect the validity of the remaining provisions of this Section 9‑102.1.
    (g) After January 1, 2001, no contract for electric service may be entered into under any schedule filed pursuant to the provisions of subsection (a) of this Section or under any schedule referred to in subsection (b) of this Section. The foregoing provision shall not affect any contract entered into prior to January 1, 2001.
    (h) Nothing contained in this Section shall be construed as preventing any customer or other appropriate party from filing a complaint or otherwise requesting that the Commission investigate the reasonableness of the terms and conditions of any schedule filed under this Section or referred to in subsection (b) of this Section. Nothing contained in this Section shall be construed as affecting the right of any customer or public utility to enter into and enforce any contract providing for the amounts to be charged for service where the contract is or has been filed pursuant to any other Section of this Act. Nothing contained in this Section shall be construed to limit any Commission authority to authorize a public utility to engage in experimental programs relating to competition, including direct access programs.

    (220 ILCS 5/9‑103) (from Ch. 111 2/3, par. 9‑103)
    Sec. 9‑103. Posting of rate schedules. Subject to such rules and regulations as the Commission may prescribe, the schedules referred to in Section 9‑102 shall be posted or kept on file in every office of a public utility where the public transacts business with such public utility. Any or all of such schedules kept as aforesaid shall be immediately produced by such public utility for inspection upon the demand of any person. A notice printed in bold type, in size prescribed by the Commission, stating that such schedules are on file with the agent and open to inspection by any person, and that the agent will assist any person to determine from such schedules any rates or other charges, classification, rules or regulations in force, shall be kept posted by the public utility in two public and conspicuous places in every such office. The form of every such schedule shall be prescribed by the Commission: Provided, that in lieu of filing the entire schedule in each office, any public utility may, subject to the regulations of the Commission, file or keep posted at such office, schedules of such rates or other charges, classifications, rules and regulations relating thereto, as are applicable at, to and from the place where such office is located.
    The Commission may determine and prescribe the form in which the schedules required by this Act to be filed with the Commission and to be kept open to public inspection shall be prepared and arranged, and may change the form from time to time if it shall be found expedient.

    (220 ILCS 5/9‑104) (from Ch. 111 2/3, par. 9‑104)
    Sec. 9‑104. No public utility shall undertake to perform any service or to furnish any product or commodity unless or until the rates and other charges and classifications, rules and regulations relating thereto, applicable to such service, product or commodity, have been filed and published in accordance with the provisions of this Act: Provided, that in cases of emergency, a service, product or commodity not specifically covered by the schedules filed, may be performed or furnished at a reasonable rate, which rate shall forthwith be filed and shall be subject to review in accordance with the provisions of this Act.
(Source: P.A. 84‑617.)

    (220 ILCS 5/9‑201)(from Ch. 111 2/3, par. 9‑201)
    Sec. 9‑201. (a) Unless the Commission otherwise orders, and except as otherwise provided in this Section, no change shall be made by any public utility in any rate or other charge or classification, or in any rule, regulation, practice or contract relating to or affecting any rate or other charge, classification or service, or in any privilege or facility, except after 45 days' notice to the Commission and to the public as herein provided. Such notice shall be given by filing with the Commission and keeping open for public inspection new schedules or supplements stating plainly the change or changes to be made in the schedule or schedules then in force, and the time when the change or changes will go into effect, and by publication in a newspaper of general circulation or such other notice to persons affected by such change as may be prescribed by rule of the Commission. The Commission, for good cause shown, may allow changes without requiring the 45 days' notice herein provided for, by an order specifying the changes so to be made and the time when they shall take effect and the manner in which they shall be filed and published.
    When any change is proposed in any rate or other charge, or classification, or in any rule, regulation, practice, or contract relating to or affecting any rate or other charge, classification or service, or in any privilege or facility, such proposed change shall be plainly indicated on the new schedule filed with the Commission, by some character to be designated by the Commission, immediately preceding or following the item.
    When any public utility providing water or sewer service proposes any change in any rate or other charge, or classification, or in any rule, regulation, practice, or contract relating to or affecting any rate or other charge, classification or service, or in any privilege or facility, such utility shall, in addition to the other notice requirements of this Act, provide notice of such change to all customers potentially affected by including a notice and description of such change, and of Commission procedures for intervention, in the first bill sent to each such customer after the filing of the proposed change.
    (b) Whenever there shall be filed with the Commission any schedule stating an individual or joint rate or other charge, classification, contract, practice, rule or regulation, the Commission shall have power, and it is hereby given authority, either upon complaint or upon its own initiative without complaint, at once, and if it so orders, without answer or other formal pleadings by the interested public utility or utilities, but upon reasonable notice, to enter upon a hearing concerning the propriety of such rate or other charge, classification, contract, practice, rule or regulation, and pending the hearing and decision thereon, such rate or other charge, classification, contract, practice, rule or regulation shall not go into effect. The period of suspension of such rate or other charge, classification, contract, practice, rule or regulation shall not extend more than 105 days beyond the time when such rate or other charge, classification, contract, practice, rule or regulation would otherwise go into effect unless the Commission, in its discretion, extends the period of suspension for a further period not exceeding 6 months.
    All rates or other charges, classifications, contracts, practices, rules or regulations not so suspended shall, on the expiration of 45 days from the time of filing the same with the Commission, or of such lesser time as the Commission may grant, go into effect and be the established and effective rates or other charges, classifications, contracts, practices, rules and regulations, subject to the power of the Commission, after a hearing had on its own motion or upon complaint, as herein provided, to alter or modify the same.
    Within 30 days after such changes have been authorized by the Commission, copies of the new or revised schedules shall be posted or filed in accordance with the terms of Section 9‑103 of this Act, in such a manner that all changes shall be plainly indicated. The Commission shall incorporate into the period of suspension a review period of 4 business days during which the Commission may review and determine whether the new or revised schedules comply with the Commission's decision approving a change to the public utility's rates. Such review period shall not extend the suspension period by more than 2 days. Absent notification to the contrary within the 4 business day period, the new or revised schedules shall be deemed approved.
    (c) If the Commission enters upon a hearing concerning the propriety of any proposed rate or other charge, classification, contract, practice, rule or regulation, the Commission shall establish the rates or other charges, classifications, contracts, practices, rules or regulations proposed, in whole or in part, or others in lieu thereof, which it shall find to be just and reasonable. In such hearing, the burden of proof to establish the justness and reasonableness of the proposed rates or other charges, classifications, contracts, practices, rules or regulations, in whole and in part, shall be upon the utility. The utility, the staff of the Commission, the Attorney General, or any party to a proceeding initiated under this Section who has been granted intervenor status and submitted a post‑hearing brief must be given the opportunity to present oral argument, if requested no later than the date for filing exceptions, on the propriety of any proposed rate or other charge, classification, contract, practice, rule, or regulation. No rate or other charge, classification, contract, practice, rule or regulation shall be found just and reasonable unless it is consistent with Sections of this Article.
    (d) Except where compliance with Section 8‑401 of this Act is of urgent and immediate concern, no representative of a public utility may discuss with a commissioner, commissioner's assistant, or hearing examiner in a non‑public setting a planned filing for a general rate increase. If a public utility makes a filing under this Section, then no substantive communication by any such person with a commissioner, commissioner's assistant or hearing examiner concerning the filing is permitted until a notice of hearing has been issued. After the notice of hearing has been issued, the only communications by any such person with a commissioner, commissioner's assistant, or hearing examiner concerning the filing permitted are communications permitted under Section 10‑103 of this Act. If any such communication does occur, then within 5 days of the docket being initiated all details relating to the communication shall be placed on the public record of the proceeding. The record shall include any materials, whether written, recorded, filmed, or graphic in nature, produced or reproduced on any media, used in connection with the communication. The record shall reflect the names of all persons who transmitted, received, or were otherwise involved in the communication, the duration of the communication, and whether the communication occurred in person or by other means. In the case of an oral communication, the record shall also reflect the location or locations of all persons involved in the communication and, if the communication occurred by telephone, the telephone numbers for the callers and recipients of the communication. A commissioner, commissioner's assistant, or hearing examiner who is involved in any such communication shall be recused from the affected proceeding. The Commission, or any commissioner or hearing examiner presiding over the proceeding shall, in the event of a violation of this Section, take action necessary to ensure that such violation does not prejudice any party or adversely affect the fairness of the proceedings including dismissing the affected proceeding. Nothing in this subsection (d) is intended to preclude otherwise allowable updates on issues that may be indirectly related to a general rate case filing because cost recovery for the underlying activity may be requested. Such updates may include, without limitation, issues related to outages and restoration, credit ratings, security issuances, reliability, Federal Energy Regulatory Commission matters, Federal Communications Commission matters, regional reliability organizations, consumer education, or labor matters, provided that such updates may not include cost recovery in a planned rate case.

    (220 ILCS 5/9‑201.5)
    Sec. 9‑201.5. Decommissioning nuclear power plants; rates.
    (a) The Commission may after hearing, in a rate case or otherwise, authorize the institution of rate provisions or tariffs that increase or decrease charges to customers to reflect changes in, or additional or reduced costs of, decommissioning nuclear power plants, including accruals for estimates of those costs, irrespective of any changes in other costs or revenues; provided the revenues collected under such rates or tariffs are used to recover costs associated with contributions to appropriate decommissioning trust funds or to reduce the amounts to be charged under such rates or tariffs in the future. These provisions or tariffs shall hereinafter be referred to as "decommissioning rates".
    (b) A public utility that does not have a decommissioning rate in effect on the effective date of this amendatory Act of 1994 may not place a decommissioning rate in effect before January 1, 1995. Changes in charges under a decommissioning rate shall not be subject to the notice and filing requirements of subsection (a) of Section 9‑201 of this Act, but a decommissioning rate of a utility that does not have such a rate in effect before the effective date of this amendatory Act of 1994 shall provide that no increase in charges under that rate may take effect until 60 days after the utility provides the proposed increased charge to the Commission for review. The Commission may require that a decommissioning rate contain provisions for reconciling amounts collected under the rate with both reasonably projected costs and actual costs prudently incurred. As used in this Section, "decommissioning costs" and "decommissioning trust fund" have the same meaning as in Section 8‑508.1 of this Act.
    (c) Nothing contained in this amendatory Act of 1994 shall affect any determination of the authority of the Commission before the effective date of this amendatory Act of 1994. Nothing contained in this amendatory Act of 1994 shall be used in any determination of the authority of the Commission after the effective date of this amendatory Act of 1994, except with respect to decommissioning rates.
    (d) A decommissioning rate authorized by the Commission under this Section and the decommissioning cost studies underlying the rate shall be subject to hearing and review, in a rate case or otherwise, not less than once every 6 years.

    (220 ILCS 5/9‑202) (from Ch. 111 2/3, par. 9‑202)
    Sec. 9‑202. (a) Whenever the Commission is of the opinion and so finds after an examination of any report or reports, annual or otherwise, filed with the Commission by any public utility, together with any other facts or information which the Commission may acquire or receive from an investigation of the books, records or papers or from an inspection of the property of such public utility, that the net income of such public utility after reasonable deductions for depreciation and other proper and necessary reserves, is in excess of the amount required for a reasonable return upon the value of said public utility's property used and useful in rendering its service to the public, provided however that in computing net income, deductions shall not be made for advertising expenses as prohibited under Section 9‑225 of this Act, and if the Commission is of the opinion and so finds in said cause that a hearing to determine all of the issues involved in a final determination of rates or services will require more than 105 days of elapsed time, the Commission shall have the power in cases of such emergency and it is hereby given authority to at once enter a temporary order, after notice to said public utility, fixing a temporary schedule of rates, which order shall be forthwith binding upon said public utility; provided, however, that the Commission's power to order reductions in rates and charges of any public utility by means of any such temporary order, is limited to reductions which will absorb not more than the amount found by the Commission to be in excess of the amount of income as determined by the Commission necessary to provide a reasonable return on the value of the property of said public utility as found by the Commission as aforesaid; and provided, further, however, that no such temporary order shall remain in force or effect for a longer period than 9 months from its effective date, and a further period not to exceed 3 months in addition if so ordered by the Commission; and provided, further, that if upon the final disposition of the issues involved in such proceeding, the rates or charges as finally determined by said Commission or the court having jurisdiction of the subject matter are in excess of the rates and charges prescribed in said temporary order, then and in such event such public utility shall be permitted over such reasonable time as the Commission shall fix, to amortize and recover by means of a temporary increase over and above the rates and charges finally determined, such sum as shall represent the difference between the gross income obtained from the rates and charges prescribed in said temporary reduction order and the gross income which would have obtained, during the period such temporary reduction order was in effect, based upon the same volume, from the rates and charges finally determined.
    (b) If the Commission enters upon a hearing concerning the propriety of any proposed rate or other charge, classification, contract, practice, rule or regulation pursuant to Section 9‑201, and if the Commission is of the opinion and so finds in said cause that a hearing to determine all of the issues involved in a final determination of rates or services will require more than 120 days of elapsed time, the Commission shall have the power to enter a temporary order fixing a temporary schedule of rates after hearing, which order shall be forthwith binding upon the public utility. As soon as practicable after the effective date of this amendatory Act of 1985, the Commission shall determine by rule the facts and circumstances which must be established by the utility in order to justify the grant of a temporary rate increase as provided herein. The Commission shall determine any temporary rate increase according to previously established standards until the time such rules become effective.
    In any case in which the Commission grants interim relief, the Commission shall, upon final disposition of the proposed permanent change in rates or other charges, classification, contract, practice, rule or regulation, also review the propriety of its prior award of interim relief based upon the criteria used by the Commission in granting the interim rate relief. If, upon such review, the Commission determines that such interim rates or charges were in excess of the rates or charges which should have been prescribed in its temporary order, the Commission shall require the public utility to refund such sum as shall represent the difference between the gross income obtained from the rates or charges prescribed in said temporary increase order and the gross income which would have been obtained during the period such temporary increase order was in effect based upon the same volume, from the rates and charges which the Commission upon final review determines were appropriate. Any refund shall include interest calculated at a rate determined by the Commission and shall be returned according to procedures prescribed by the Commission.

    (220 ILCS 5/9‑210) (from Ch. 111 2/3, par. 9‑210)
    Sec. 9‑210. The Commission shall have power to ascertain the value of the property of every public utility in this State and every fact which in its judgment may or does have any bearing on such value. In all proceedings before the Commission, initiated by the Commission upon its own motion, or initiated by an application of such public utility, in which the value of the property of any public utility or utilities is an issue, the burden of establishing such value shall be upon such public utility or utilities. In making such valuation the Commission may avail itself of any information, books, documents, or records in the possession of any officer, department or board of the State or any subdivision thereof. The Commission shall have power to make revaluation from time to time and also to ascertain the value of all new construction, extensions, and additions to the property of every public utility.
    For purposes of establishing the value of public utility property, when determining rates or charges, or for any other reason, the Commission may base its determination on the original cost of such property.

    (220 ILCS 5/9‑212) (from Ch. 111 2/3, par. 9‑212)
    Sec. 9‑212. No new electric utility generating plant or gas production facility, or significant addition to existing facilities or plant, shall be included in a utility's rate base unless and until the utility proves, and the Commission determines, that such plant or facility is both prudent and used and useful in providing utility service to the utility's customers. For purposes of this Section, "prudent" means that at the time of certification, initiation of construction and each subsequent evaluation of any construction project until the time of completion, based on the evidence introduced in any hearings and all information which was known or should have been known at the time, and relevant planning and certification criteria, it was prudent and reasonable to conclude that the generating or production facility would be used and useful in providing service to customers at the time of completion. If the Commission has issued a certificate of public convenience and necessity for the completed facility, and to the extent that the Commission approves continued construction upon reevaluation subsequent to certification, such actions shall constitute prima facie evidence of the prudence of construction. If the Commission determines as a result of reevaluation during construction that the facility should not be completed, such determination shall constitute prima facie evidence that subsequent construction expenditures were imprudent.
    A generation or production facility is used and useful only if, and only to the extent that, it is necessary to meet customer demand or economically beneficial in meeting such demand. No generation or production facility shall be found used and useful until and unless it is capable of generation or production at significant operating levels on a consistent and sustainable basis. Any pollution control devices for the control of sulfur dioxide emissions installed or used in accordance with, and up to the cost specified in, an order or supplemental order of the Commission entered pursuant to subsection (e) of Section 8‑402.1 shall be deemed prudent and shall, upon being placed into operation on a consistent, sustainable basis by the public utility, be deemed used and useful.

    (220 ILCS 5/9‑213) (from Ch. 111 2/3, par. 9‑213)
    Sec. 9‑213. The cost of new electric utility generating plants and significant additions to electric utility generating plants shall not be included in the rate base of any utility unless such cost is reasonable. Prior to including the cost of plants or additions to utility plants in the rate base, the Commission shall conduct an audit of such costs in order to ascertain whether the cost associated with the new generating plant or the addition to electric utility generating plant is reasonable. However, the Commission may, for good cause shown in individual cases, waive the auditing requirement for any generating facility which meets all of the following requirements:
        (1) the facility is wholly owned and operated by a
     public utility, as otherwise defined in this Act, which serves less than 20,000 electric customers within the State of Illinois, and
        (2) the facility is designed to generate less than
     50 megawatts of electricity, and
        (3) the facility is located outside of the State of
     Illinois.
    If the Commission is unable to conduct such an audit, the Commission shall arrange for it to be conducted by persons independent of the utility and selected by the Commission. The cost of such an independent audit shall be borne initially by the utility, but shall be recovered as an expense through normal ratemaking procedures. Any such audits shall be conducted in accordance with generally accepted auditing standards and shall include but not be limited to costs associated with materials, labor, equipment, professional services and other direct and indirect costs.
    "Significant additions to the electric utility generating plant", as used in this Section, shall not include a public utility's investment in pollution control devices for the control of sulfur dioxide emissions. Nothing in this Section is intended to affect the provisions of Section 9‑214 of this Act.
    "Reasonable", as used in this Section, means that a utility's decisions, construction, and supervision of construction, underlying the costs of new electric utility generating plants and significant additions to electric utility generating plants resulted in efficient, economical and timely construction. In determining the reasonableness of plant costs, the Commission shall consider the knowledge and circumstances prevailing at the time of each relevant utility decision or action.
    Nothing in this Section shall prevent or limit the Commission from either entering into and conducting joint audits concerning such electric generating plants with the regulatory authority of another state, or from relying on audits conducted by the regulatory authority of another state in lieu of an audit as required by this Section.

    (220 ILCS 5/9‑214) (from Ch. 111 2/3, par. 9‑214)
    Sec. 9‑214. (a) As used in this Section:
        (1) "CWIP" means those assets which are recorded as
     construction work in progress on a public utility's books of accounts maintained in accordance with the applicable regulations and orders of the Commission.
        (2) "Rate base" means the original cost value of the
     property on which a return is allowed.
        (3) "CWIP ratio" means the fraction, expressed as a
     percentage, calculated by dividing the amount of CWIP included in a public utility's rate base by the utility's rate base.
        (4) "Existing CWIP" means the amount of CWIP
     included in the rate base on December 1, 1983.
    (b) In any determination under Section 9‑201, 9‑202 or 9‑250 of this Act in a proceeding begun on or after December 1, 1983:
        (1) For any public utility with a CWIP ratio on
     December 1, 1983, which is less than 15%, the Commission shall not include in the rate base for such public utility an amount for CWIP to exceed 80% of existing CWIP for the period from December 1, 1983 through December 31, 1984, and 60% of existing CWIP for the period from January 1, 1985 through December 31, 1985 and 40% of existing CWIP for the period from January 1, 1986 through December 31, 1986, and 20% of existing CWIP for the period from January 1, 1987 through December 31, 1987.
        (2) For any public utility with a CWIP ratio on
     December 1, 1983 which is greater than or equal to 15%, the Commission shall not include in the rate base for such public utility an amount for CWIP in excess of the amount of CWIP included in the rate base on December 1, 1983, plus 50% of the allowed construction expenses incurred by the public utility from the date of the most recent rate determination by the Commission prior to December 1, 1983.
    (c) The limitations set forth in paragraph (b) of this Section shall not be interpreted as an expansion of the Commission's authority to include CWIP in the rate base, but rather solely as a limitation thereon.
    (d) The Commission shall not include an amount for CWIP in the rate base for any public utility for the period after December 31, 1988.
    (e) Notwithstanding the provisions of paragraphs (b) and (d) of this Section the Commission may include in the rate base of a public utility an amount for CWIP for a public utility's investment which is scheduled to be placed in service within 12 months of the date of the rate determination. For the purposes of this paragraph nuclear generating facilities shall be considered to be in service upon the commencement of electric generation.
    (f) Notwithstanding the provisions of paragraph (b) and (d), the Commission may include in the rate base of a public utility an amount of CWIP for a public utility's investment in pollution control devices for the control of sulfur dioxide emissions and the purification of water and sewage; provided, however, that upon application by a public utility which is constructing one or more pollution control devices for the control of sulfur dioxide emissions as part of a Clean Air Act compliance plan approved by the Commission pursuant to subsection (e) of Section 8‑402.1, the Commission shall include in such public utility's rate base an amount of CWIP equal to its investment in such pollution control device or devices, but not to exceed the estimated cost of such facilities specified in the Commission's order or supplemental order pursuant to subsection (e) of Section 8‑402.1. For purposes of this subsection (f), the public utility's investment shall not include the amount of any state, federal or other grants provided to the public utility to fund the design, acquisition, construction, installation and testing of pollution control devices for the control of sulfur dioxide emissions.
    (g) Except for those amounts of CWIP described in paragraphs (e) and (f) of this Section, the Commission shall consider, in any rate filing subsequent to the coming on line of any new utility plant where CWIP funds have been allowed in rate base, a rate moderation plan directed towards allowing an appropriate return to ratepayers for previous amounts attributable to CWIP funds.
    The Commission shall conduct an investigation and study of the costs and benefits to ratepayers of the inclusion of construction work in progress in rate base. Such study shall include a full opportunity for participation by the public through notice and hearings. If the Commission determines that in certain circumstances the inclusion of CWIP in rate base would be demonstrably beneficial to ratepayers, the Commission shall report its findings with recommendations to the General Assembly by December 31, 1988.
