    (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.
    (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. 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.

    (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.
(Source: P.A. 84‑617.)

    (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.

    (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.

The Commission shall have power to consider, on a case by case basis, the status of a utility's capacity and to determine whether or not such utility's capacity is in excess of that reasonably necessary to provide adequate and reliable electric service. Excess capacity for purposes of this Section shall mean capacity in excess of that reasonably necessary to provide adequate and reliable electric service. Such consideration shall be related to the utility's historic and projected peak.
    The Commission is empowered to make appropriate and equitable adjustments to rates for utility service upon a finding of excess capacity.
    With respect to generating capacity existing or under construction on the effective date of this amendatory Act of 1985, any such determination and adjustment to rates, and any determination as to whether such capacity is used and useful for any purpose under this Act, shall be limited to the determination and adjustment, if any, appropriate under the law in effect prior to such effective date.

    (220 ILCS 5/9‑220)(from Ch. 111 2/3, par. 9‑220)
    Sec. 9‑220. Rate changes based on changes in fuel costs.
    (a) Notwithstanding the provisions of Section 9‑201, the Commission may authorize the increase or decrease of rates and charges based upon changes in the cost of fuel used in the generation or production of electric power, changes in the cost of purchased power, or changes in the cost of purchased gas through the application of fuel adjustment clauses or purchased gas adjustment clauses. The Commission may also authorize the increase or decrease of rates and charges based upon expenditures or revenues resulting from the purchase or sale of emission allowances created under the federal Clean Air Act Amendments of 1990, through such fuel adjustment clauses, as a cost of fuel. For the purposes of this paragraph, cost of fuel used in the generation or production of electric power shall include the amount of any fees paid by the utility for the implementation and operation of a process for the desulfurization of the flue gas when burning high sulfur coal at any location within the State of Illinois irrespective of the attainment status designation of such location; but shall not include transportation costs of coal (i) except to the extent that for contracts entered into on and after the effective date of this amendatory Act of 1997, the cost of the coal, including transportation costs, constitutes the lowest cost for adequate and reliable fuel supply reasonably available to the public utility in comparison to the cost, including transportation costs, of other adequate and reliable sources of fuel supply reasonably available to the public utility, or (ii) except as otherwise provided in the next 3 sentences of this paragraph. Such costs of fuel shall, when requested by a utility or at the conclusion of the utility's next general electric rate proceeding, whichever shall first occur, include transportation costs of coal purchased under existing coal purchase contracts. For purposes of this paragraph "existing coal purchase contracts" means contracts for the purchase of coal in effect on the effective date of this amendatory Act of 1991, as such contracts may thereafter be amended, but only to the extent that any such amendment does not increase the aggregate quantity of coal to be purchased under such contract. Nothing herein shall authorize an electric utility to recover through its fuel adjustment clause any amounts of transportation costs of coal that were included in the revenue requirement used to set base rates in its most recent general rate proceeding. Cost shall be based upon uniformly applied accounting principles. Annually, the Commission shall initiate public hearings to determine whether the clauses reflect actual costs of fuel, gas, power, or coal transportation purchased to determine whether such purchases were prudent, and to reconcile any amounts collected with the actual costs of fuel, power, gas, or coal transportation prudently purchased. In each such proceeding, the burden of proof shall be upon the utility to establish the prudence of its cost of fuel, power, gas, or coal transportation purchases and costs. The Commission shall issue its final order in each such annual proceeding for an electric utility by December 31 of the year immediately following the year to which the proceeding pertains, provided, that the Commission shall issue its final order with respect to such annual proceeding for the years 1996 and earlier by December 31, 1998.
    (b) A public utility providing electric service, other than a public utility described in subsections (e) or (f) of this Section, may at any time during the mandatory transition period file with the Commission proposed tariff sheets that eliminate the public utility's fuel adjustment clause and adjust the public utility's base rate tariffs by the amount necessary for the base fuel component of the base rates to recover the public utility's average fuel and power supply costs per kilowatt‑hour for the 2 most recent years for which the Commission has issued final orders in annual proceedings pursuant to subsection (a), where the average fuel and power supply costs per kilowatt‑hour shall be calculated as the sum of the public utility's prudent and allowable fuel and power supply costs as found by the Commission in the 2 proceedings divided by the public utility's actual jurisdictional kilowatt‑hour sales for those 2 years. Notwithstanding any contrary or inconsistent provisions in Section 9‑201 of this Act, in subsection (a) of this Section or in any rules or regulations promulgated by the Commission pursuant to subsection (g) of this Section, the Commission shall review and shall by order approve, or approve as modified, the proposed tariff sheets within 60 days after the date of the public utility's filing. The Commission may modify the public utility's proposed tariff sheets only to the extent the Commission finds necessary to achieve conformance to the requirements of this subsection (b). During the 5 years following the date of the Commission's order, but in any event no earlier than January 1, 2007, a public utility whose fuel adjustment clause has been eliminated pursuant to this subsection shall not file proposed tariff sheets seeking, or otherwise petition the Commission for, reinstatement of a fuel adjustment clause.
    (c) Notwithstanding any contrary or inconsistent provisions in Section 9‑201 of this Act, in subsection (a) of this Section or in any rules or regulations promulgated by the Commission pursuant to subsection (g) of this Section, a public utility providing electric service, other than a public utility described in subsection (e) or (f) of this Section, may at any time during the mandatory transition period file with the Commission proposed tariff sheets that establish the rate per kilowatt‑hour to be applied pursuant to the public utility's fuel adjustment clause at the average value for such rate during the preceding 24 months, provided that such average rate results in a credit to customers' bills, without making any revisions to the public utility's base rate tariffs. The proposed tariff sheets shall establish the fuel adjustment rate for a specific time period of at least 3 years but not more than 5 years, provided that the terms and conditions for any reinstatement earlier than 5 years shall be set forth in the proposed tariff sheets and subject to modification or approval by the Commission. The Commission shall review and shall by order approve the proposed tariff sheets if it finds that the requirements of this subsection are met. The Commission shall not conduct the annual hearings specified in the last 3 sentences of subsection (a) of this Section for the utility for the period that the factor established pursuant to this subsection is in effect.
    (d) A public utility providing electric service, or a public utility providing gas service may file with the Commission proposed tariff sheets that eliminate the public utility's fuel or purchased gas adjustment clause and adjust the public utility's base rate tariffs to provide for recovery of power supply costs or gas supply costs that would have been recovered through such clause; provided, that the provisions of this subsection (d) shall not be available to a public utility described in subsections (e) or (f) of this Section to eliminate its fuel adjustment clause. Notwithstanding any contrary or inconsistent provisions in Section 9‑201 of this Act, in subsection (a) of this Section, or in any rules or regulations promulgated by the Commission pursuant to subsection (g) of this Section, the Commission shall review and shall by order approve, or approve as modified in the Commission's order, the proposed tariff sheets within 240 days after the date of the public utility's filing. The Commission's order shall approve rates and charges that the Commission, based on information in the public utility's filing or on the record if a hearing is held by the Commission, finds will recover the reasonable, prudent and necessary jurisdictional power supply costs or gas supply costs incurred or to be incurred by the public utility during a 12 month period found by the Commission to be appropriate for these purposes, provided, that such period shall be either (i) a 12 month historical period occurring during the 15 months ending on the date of the public utility's filing, or (ii) a 12 month future period ending no later than 15 months following the date of the public utility's filing. The public utility shall include with its tariff filing information showing both (1) its actual jurisdictional power supply costs or gas supply costs for a 12 month historical period conforming to (i) above and (2) its projected jurisdictional power supply costs or gas supply costs for a future 12 month period conforming to (ii) above. If the Commission's order requires modifications in the tariff sheets filed by the public utility, the public utility shall have 7 days following the date of the order to notify the Commission whether the public utility will implement the modified tariffs or elect to continue its fuel or purchased gas adjustment clause in force as though no order had been entered. The Commission's order shall provide for any reconciliation of power supply costs or gas supply costs, as the case may be, and associated revenues through the date that the public utility's fuel or purchased gas adjustment clause is eliminated. During the 5 years following the date of the Commission's order, a public utility whose fuel or purchased gas adjustment clause has been eliminated pursuant to this subsection shall not file proposed tariff sheets seeking, or otherwise petition the Commission for, reinstatement or adoption of a fuel or purchased gas adjustment clause. Nothing in this subsection (d) shall be construed as limiting the Commission's authority to eliminate a public utility's fuel adjustment clause or purchased gas adjustment clause in accordance with any other applicable provisions of this Act.
    (e) Notwithstanding any contrary or inconsistent provisions in Section 9‑201 of this Act, in subsection (a) of this Section, or in any rules promulgated by the Commission pursuant to subsection (g) of this Section, a public utility providing electric service to more than 1,000,000 customers in this State may, within the first 6 months after the effective date of this amendatory Act of 1997, file with the Commission proposed tariff sheets that eliminate, effective January 1, 1997, the public utility's fuel adjustment clause without adjusting its base rates, and such tariff sheets shall be effective upon filing. To the extent the application of the fuel adjustment clause had resulted in net charges to customers after January 1, 1997, the utility shall also file a tariff sheet that provides for a refund stated on a per kilowatt‑hour basis of such charges over a period not to exceed 6 months; provided however, that such refund shall not include the proportional amounts of taxes paid under the Use Tax Act, Service Use Tax Act, Service Occupation Tax Act, and Retailers' Occupation Tax Act on fuel used in generation. The Commission shall issue an order within 45 days after the date of the public utility's filing approving or approving as modified such tariff sheet. If the fuel adjustment clause is eliminated pursuant to this subsection, the Commission shall not conduct the annual hearings specified in the last 3 sentences of subsection (a) of this Section for the utility for any period after December 31, 1996 and prior to any reinstatement of such clause. A public utility whose fuel adjustment clause has been eliminated pursuant to this subsection shall not file a proposed tariff sheet seeking, or otherwise petition the Commission for, reinstatement of the fuel adjustment clause prior to January 1, 2007.
    (f) Notwithstanding any contrary or inconsistent provisions in Section 9‑201 of this Act, in subsection (a) of this Section, or in any rules or regulations promulgated by the Commission pursuant to subsection (g) of this Section, a public utility providing electric service to more than 500,000 customers but fewer than 1,000,000 customers in this State may, within the first 6 months after the effective date of this amendatory Act of 1997, file with the Commission proposed tariff sheets that eliminate, effective January 1, 1997, the public utility's fuel adjustment clause and adjust its base rates by the amount necessary for the base fuel component of the base rates to recover 91% of the public utility's average fuel and power supply costs for the 2 most recent years for which the Commission, as of January 1, 1997, has issued final orders in annual proceedings pursuant to subsection (a), where the average fuel and power supply costs per kilowatt‑hour shall be calculated as the sum of the public utility's prudent and allowable fuel and power supply costs as found by the Commission in the 2 proceedings divided by the public utility's actual jurisdictional kilowatt‑hour sales for those 2 years, provided, that such tariff sheets shall be effective upon filing. To the extent the application of the fuel adjustment clause had resulted in net charges to customers after January 1, 1997, the utility shall also file a tariff sheet that provides for a refund stated on a per kilowatt‑hour basis of such charges over a period not to exceed 6 months. Provided however, that such refund shall not include the proportional amounts of taxes paid under the Use Tax Act, Service Use Tax Act, Service Occupation Tax Act, and Retailers' Occupation Tax Act on fuel used in generation. The Commission shall issue an order within 45 days after the date of the public utility's filing approving or approving as modified such tariff sheet. If the fuel adjustment clause is eliminated pursuant to this subsection, the Commission shall not conduct the annual hearings specified in the last 3 sentences of subsection (a) of this Section for the utility for any period after December 31, 1996 and prior to any reinstatement of such clause. A public utility whose fuel adjustment clause has been eliminated pursuant to this subsection shall not file a proposed tariff sheet seeking, or otherwise petition the Commission for, reinstatement of the fuel adjustment clause prior to January 1, 2007.
    (g) The Commission shall have authority to promulgate rules and regulations to carry out the provisions of this Section.
    (h) Any gas utility may enter into a 20‑year supply contract with any company for synthetic natural gas produced from coal through the gasification process if the company has commenced construction of a coal gasification facility by July 1, 2008. The cost for the synthetic natural gas is reasonable and prudent and recoverable through the purchased gas adjustment clause for years one through 10 of the contract if: (i) the only coal used in the gasification process has high volatile bituminous rank and greater than 1.7 pounds of sulfur per million Btu content; (ii) at the time the contract term commences, the price per million Btu does not exceed $5 in 2004 dollars, adjusted annually based on the change in the Annual Consumer Price Index for All Urban Consumers for the Midwest Region as published in April by the United States Department of Labor, Bureau of Labor Statistics (or a suitable Consumer Price Index calculation if this Consumer Price Index is not available) for the previous calendar year; provided that the price per million Btu shall not exceed $5.50 at any time during the contract; (iii) the utility's aggregate long‑term supply contracts for the purchase of synthetic natural gas produced from coal through the gasification process does not exceed 25% of the annual system supply requirements of the utility at the time the contract is entered into; and (iv) the contract is entered into within one year after the effective date of this amendatory Act of the 94th General Assembly and terminates 20 years after the commencement of the production of synthetic natural gas. The contract shall provide that if, at any time during years 11 through 20 of the contract, the Commission determines that the cost for the synthetic natural gas under the contract is not reasonable and prudent, then the company shall reimburse the utility for the difference between the cost deemed reasonable and prudent by the Commission and the cost imposed under the contract.
    (i) If a gas utility or an affiliate of a gas utility has an ownership interest in any entity that produces or sells synthetic natural gas, Article VII of this Act shall apply.

    Sec. 9‑221. Whenever a municipality pursuant to Section 8‑11‑2 of the Illinois Municipal Code, as heretofore and hereafter amended, imposes a tax on any public utility, such utility may charge its customers, other than customers who are certified business enterprises under paragraph (e) of Section 8‑11‑2 of the Illinois Municipal Code or are exempted from those taxes under paragraph (f) of that Section, to the extent of such exemption and during the period in which such exemption is in effect, in addition to any rate authorized by this Act, an additional charge equal to the sum of (1) an amount equal to such municipal tax, or any part thereof (2) 3% of such tax, or any part thereof, as the case may be, to cover costs of accounting, and (3) an amount equal to the increase in taxes and other payments to governmental bodies resulting from the amount of such additional charge. Such utility shall file with the Commission a true and correct copy of the municipal ordinance imposing such tax; and also shall file with the Commission a supplemental schedule applicable to such municipality which shall specify such additional charge and which shall become effective upon filing without further notice. Such additional charge shall be shown separately on the utility bill to each customer. The Commission shall have power to investigate whether or not such supplemental schedule correctly specifies such additional charge, but shall have no power to suspend such supplemental schedule. If the Commission finds, after a hearing, that such supplemental schedule does not correctly specify such additional charge, it shall by order require a refund to the appropriate customers of the excess, if any, with interest, in such manner as it shall deem just and reasonable, and in and by such order shall require the utility to file an amended supplemental schedule corresponding to the finding and order of the Commission.

    Sec. 9‑222.2. Additional Charge ‑ Recovery. The additional charge authorized by Section 9‑221 or Section 9‑222 shall be made (i) in the case of a tax measured by gross receipts or gross revenue, by adding to the customer's bill a uniform percentage to those amounts payable by the customer for intrastate utility service which are includible in the measure of such tax, except, however, such method is not required where practical considerations justify a utility's or telecommunications carrier's use of another just and reasonable method of recovering its entire liability for such tax, and (ii) in the case of a tax measured by the number of therms or kilowatt‑hours distributed, supplied, furnished, sold, transported or transmitted, by adding to the customer's bill an amount equal to the number of therms or kilowatt‑hours which are includible in the measure of such tax, multiplied by the applicable tax rate. Without limiting the generality of the foregoing, it shall not be deemed unjust and unreasonable or a violation of Section 9‑241 for telecommunications carriers to recover the expense of taxes imposed by any municipality pursuant to Section 8‑11‑2 of the Illinois Municipal Code on coin revenues generated by coin‑operated telecommunications devices by including the expense of the tax within the coin rates for intra‑state coin paid telecommunications services.

    (a) If a telecommunications carrier is required to make a refund as a result of an additional charge collected to recover the expense of taxes imposed by any municipality pursuant to Section 8‑11‑2 of the Illinois Municipal Code on revenues generated by coin‑operated telecommunications devices, the telecommunications carrier shall be entitled to amortize the total amount refunded over a reasonable period not to exceed 5 years and shall be permitted to recover such refunded amount in full over the amortization period by means of temporary supplemental rates approved by the Illinois Commerce Commission applicable to that carrier's intrastate utility services paid for by inserting coins in coin‑operated telecommunications devices. The Commission shall monitor the amortization of the expense and discontinue any temporary supplemental rate as to each municipality immediately when the recovery of the expense is complete. This provision shall be applicable only if all of the following conditions are met:
        (1) The refund is made pursuant to a final judgment
    
of a court of competent jurisdiction, including a judgment approving settlement of a disputed claim.

recovered the expense of taxes paid to a governmental body, plus the expense of collection as authorized by Section 9‑221, and such amounts have not been recovered by the telecommunications carrier from the public body.
    (b) This amendatory Act of 1991 shall be applicable to all refunds made on or subsequent to June 1, 1991, including but not limited to refunds made pursuant to judgments entered before the effective date of this amendatory Act of 1991.

    Sec. 9‑223. Fire protection charge.
    (a) The Commission may authorize any public utility engaged in the production, storage, transmission, sale, delivery or furnishing of water to impose a fire protection charge, in addition to any rate authorized by this Act, sufficient to cover a reasonable portion of the cost of providing the capacity, facilities and the water necessary to meet the fire protection needs of any municipality or public fire protection district. Such fire protection charge shall be in the form of a fixed amount per bill and shall be shown separately on the utility bill of each customer of the municipality or fire protection district. Any filing by a public utility to impose such a fire protection charge or to modify a charge shall be made pursuant to Section 9‑201 of this Act. Any fire protection charge imposed shall reflect the costs associated with providing fire protection service for each municipality or fire protection district. No such charge shall be imposed directly on any municipality or fire protection district for a reasonable level of fire protection services unless provided for in a separate agreement between the municipality or the fire protection district and the utility.
    (b) By December 31, 2007, the Commission shall conduct at least 3 public forums to evaluate the purpose and use of each fire protection charge imposed under this Section. At least one forum must be held in northern Illinois, at least one forum must be held in central Illinois, and at least one forum must be held in southern Illinois. The Commission must invite a representative from each municipality and fire protection district affected by a fire protection charge under this Section to attend a public forum. The Commission shall report its findings concerning recommendations concerning the purpose and use of each fire protection charge to the General Assembly no later than the last day of the veto session in 2008.

    (2) In any general rate increase requested by any gas or electric utility company under the provisions of this Act, the Commission shall not consider, for the purpose of determining any rate, charge or classification of costs, any direct or indirect expenditures for promotional, political, institutional or goodwill advertising, unless the Commission finds the advertising to be in the best interest of the Consumer or authorized as provided pursuant to subsection 3 of this Section.
    (3) The following categories of advertising shall be considered allowable operating expenses for gas or electric utilities:

In determining the reasonableness of such donations, the Commission may not establish, by rule, a presumption that any particular portion of an otherwise reasonable amount may not be considered as an operating expense. The Commission shall be prohibited from disallowing by rule, as an operating expense, any portion of a reasonable donation for public welfare or charitable purposes.

    Sec. 9‑240. Except as in this Act otherwise provided, no public utility shall charge, demand, collect or receive a greater or less or different compensation for any product, or commodity furnished or to be furnished, or for any service rendered or to be rendered, than the rates or other charges applicable to such product or commodity or service as specified in its schedules on file and in effect at the time, except as provided in Section 9‑104, nor shall any such public utility refund or remit, directly or indirectly, in any manner or by any device, any portion of the rates or other charges so specified, nor extend to any corporation or person any form of contract or agreement or any rule or regulation or any facility or privilege except such as are regularly and uniformly extended to all corporations and persons.
    No law of the State shall be construed to prohibit a public utility from furnishing its service, product or commodity to its employees, officers, directors or pensioners, or its employees, officers, directors or pensioners from receiving such service, product or commodity, free or at rates or charges less than those specified in its filed schedules.
(Source: P.A. 84‑617.)

    (220 ILCS 5/9‑241) (from Ch. 111 2/3, par. 9‑241)
    Sec. 9‑241. No public utility shall, as to rates or other charges, services, facilities or in other respect, make or grant any preference or advantage to any corporation or person or subject any corporation or person to any prejudice or disadvantage. No public utility shall establish or maintain any unreasonable difference as to rates or other charges, services, facilities, or in any other respect, either as between localities or as between classes of service.
    However, nothing in this Section shall be construed as limiting the authority of the Commission to permit the establishment of economic development rates as incentives to economic development either in enterprise zones as designated by the State of Illinois or in other areas of a utility's service area. Such rates should be available to existing businesses which demonstrate an increase to existing load as well as new businesses which create new load for a utility so as to create a more balanced utilization of generating capacity. The Commission shall ensure that such rates are established at a level which provides a net benefit to customers within a public utility's service area.
    Prior to October 1, 1989, no public utility providing electrical or gas service shall consider the use of solar or other nonconventional renewable sources of energy by a customer as a basis for establishing higher rates or charges for any service or commodity sold to such customer; nor shall a public utility subject any customer utilizing such energy source or sources to any other prejudice or disadvantage on account of such use. No public utility shall without the consent of the Commission, charge or receive any greater compensation in the aggregate for a lesser commodity, product, or service than for a greater commodity, product or service of like character.
    The Commission, in order to expedite the determination of rate questions, or to avoid unnecessary and unreasonable expense, or to avoid unjust or unreasonable discrimination between classes of customers, or, whenever in the judgment of the Commission public interest so requires, may, for rate making and accounting purposes, or either of them, consider one or more municipalities either with or without the adjacent or intervening rural territory as a regional unit where the same public utility serves such region under substantially similar conditions, and may within such region prescribe uniform rates for consumers or patrons of the same class.
    Any public utility, with the consent and approval of the Commission, may as a basis for the determination of the charges made by it classify its service according to the amount used, the time when used, the purpose for which used, and other relevant factors.

    Sec. 9‑242. The Commission shall study the costs and benefits of implementing promotional rates for a public utility's industrial and commercial customers when such rates are intended to encourage increased consumption of gas or electric service by such customers, to increase employment or production by such customers, or to improve the likelihood that existing customers will remain, or additional industrial or commercial customers will locate, in Illinois. The Commission shall include in its study, in particular, an analysis of (1) the extent to which existing industrial and commercial customers change short‑term production or employment levels in response to any change in prices for gas or electric service; (2) the extent to which industrial and commercial customers base long‑term location, production and employment decisions on the short‑term and long‑term prices of gas or electric service; and (3) the extent to which rates or charges paid by utility customers other than those directly benefitting from promotional rates are affected by the utilization of such rates by industrial and commercial customers. The Commission's study shall be subject to hearing and comment, and the findings shall be reported to the General Assembly together with any recommendations for legislative action.

No person or corporation shall, directly or indirectly, by any device or means whatsoever, whether with or without the consent or connivance of a public utility or any of its officers, or employees, seek to obtain or obtain any service, commodity, or product at less than the rate or other charge then established and in force therefor. If prior to June 30, 1913, any real estate or other tangible property shall have been sold or transferred to any public utility or public service corporation, or, if before that date, any obligation of any public utility or public service corporation created in consideration of the transfer to it of any real estate or other tangible property, shall have been released or cancelled, upon consideration in whole or in part of an agreement by such public utility or public service corporation expressed in writing to render any service, or furnish any commodity or product in the future to the party or parties making such conveyance or transfer or owning such obligation, nothing in this Act contained shall be construed to in any way affect such agreement or to prevent the performance or enforcement thereof according to its terms, or to authorize the Commission to interfere with such performance or enforcement.

    Sec. 9‑244. Alternative rate regulation.
    (a) Notwithstanding any of the ratemaking provisions of this Article IX or other Sections of this Act, or the Commission's rules that are deemed to require rate of return regulation, and except as provided in Article XVI, the Commission, upon petition by an electric or gas public utility, and after notice and hearing, may authorize for some or all of the regulated services of that utility, the implementation of one or more programs consisting of (i) alternatives to rate of return regulation, including but not limited to earnings sharing, rate moratoria, price caps or flexible rate options, or (ii) other regulatory mechanisms that reward or penalize the utility through the adjustment of rates based on utility performance. In the case of other regulatory mechanisms that reward or penalize utilities through the adjustment of rates based on utility performance, the utility's performance shall be compared to standards established in the Commission order authorizing the implementation of other regulatory mechanisms. The Commission is specifically authorized to approve in response to such petitions different forms of alternatives to rate of return regulation or other regulatory mechanisms to fit the particular characteristics and requirements of different utilities and their service territories.
    (b) The Commission shall approve the program if it finds, based on the record, that:
        (1) the program is likely to result in rates lower
    
than otherwise would have been in effect under traditional rate of return regulation for the services covered by the program and that are consistent with the provisions of Section 9‑241 of the Act; and
        (2) the program is likely to result in other
    
substantial and identifiable benefits that would be realized by customers served under the program and that would not be realized in the absence of the program; and
        (3) the utility is in compliance with applicable
    
Commission standards for reliability and implementation of the program is not likely to adversely affect service reliability; and
        (4) implementation of the program is not likely to
    
result in deterioration of the utility's financial condition; and
        (5) implementation of the program is not likely to
    
adversely affect the development of competitive markets; and
        (6) the electric utility is in compliance with its
    
obligation to offer delivery services pursuant to Article XVI; and
        (7) the program includes annual reporting
    
requirements and other provisions that will enable the Commission to adequately monitor its implementation of the program; and
        (8) the program includes provisions for an equitable
    
sharing of any net economic benefits between the utility and its customers to the extent the program is likely to result in such benefits.
    The Commission shall issue its order approving or denying the program no later than 270 days from the date of filing of the petition. Any program approved under this Section shall continue in effect until revised, modified or terminated by order of the Commission as provided in this Section. If the Commission cannot make the above findings, it shall specifically identify in its order the reason or reasons why the proposed program does not meet the above criteria, and shall identify any modifications supported in the record, if any, that would cause the program to satisfy the above criteria. In the event the order identifies any such modifications it shall not become a final order subject to petitions for rehearing until 15 days after service of same by the Commission. The utility shall have 14 days following the date of service of the order to notify the Commission in writing whether it will accept any modifications so identified in the order or whether it has elected not to proceed with the program. If the utility notifies the Commission that it will accept such modifications, the Commission shall issue an amended order, without further hearing, within 14 days following such notification, approving the program as modified and such order shall be considered to be a final order of the Commission subject to petitions for rehearing and appellate procedures.
    (c) The Commission shall open a proceeding to review any program approved under subsection (b) 2 years after the program is first implemented to determine whether the program is meeting its objectives, and may make such revisions, no later than 270 days after the proceeding is opened, as are necessary to result in the program meeting its objectives. A utility may elect to discontinue any program so revised. The Commission shall not otherwise direct a utility to revise, modify or cancel a program during its term of operation, except as found necessary, after notice and hearing, to ensure system reliability.
    (d) Upon its own motion or complaint, the Commission may investigate whether the utility is implementing an approved program in accordance with the Commission order approving the program. If the Commission finds after notice and hearing, that the utility is not implementing the program in accordance with such order, the Commission shall order the utility to comply with the terms of the order. Complaints relating to the program filed under Section 9‑250 of this Act, alleging that the program does not comply with that Section or the requirements of subsection (b) shall not be filed sooner than one year after the review provided for in subsection (c). The complainant shall bear the burden of proving the allegations in the complaint.
    (e) The Commission shall not be authorized to allow or order an electric utility to place a program into effect, pursuant to this Section, applicable to delivery services provided by a utility, unless the utility already has in effect a delivery services tariff conforming to the requirements of Section 16‑108 of this Act.
    (f) The Commission may, upon subsequent petition by the utility, after notice and hearing, authorize the extension of a program that was previously approved pursuant to this Section or approve revisions or modifications of such a program to be effective, after the initially approved program has been in effect. Any such petition seeking an extension, revision, or modification of such a program must be accompanied by an evaluation of the program addressing the criteria set forth in subsection (b) hereof. The utility's petition may, but is not required to, specify a termination date for the extended, revised or modified program. The Commission may require a review of the extended, revised, or modified program at such intervals as may be ordered by the Commission, for the purpose of determining whether the program should be revised, modified, or terminated.

    The Commission shall have power, upon a hearing, had upon its own motion or upon complaint, to investigate a single rate or other charge, classification, rule, regulation, contract or practice, or any number thereof, or the entire schedule or schedules of rates or other charges, classifications, rules, regulations, contracts and practices, or any thereof of any public utility, and to establish new rates or other charges, classifications, rules, regulations, contracts or practices or schedule or schedules, in lieu thereof.

    The Commission shall also have the power, after a hearing had upon its own motion or upon complaint, to order any public utilities to establish and fix reasonable and sufficient joint rates or other charges or classifications. In case such public utilities do not agree upon the division between them of such joint rates or other charges the Commission shall, after hearing, establish such division by supplemental order.

    Sec. 9‑252. When complaint is made to the Commission concerning any rate or other charge of any public utility and the Commission finds, after a hearing, that the public utility has charged an excessive or unjustly discriminatory amount for its product, commodity or service, the Commission may order that the public utility make due reparation to the complainant therefor, with interest at the legal rate from the date of payment of such excessive or unjustly discriminatory amount.
    If the public utility does not comply with an order of the Commission for the payment of money within the time fixed in such order, the complainant, or any person for whose benefit such order was made, may file in a circuit court of competent jurisdiction a complaint setting forth briefly the causes for which the person claims damages and the order of the Commission in the premises. Such action shall proceed in all respects like other civil actions for damages, except that on the trial of such action the order of the Commission shall be prima facie evidence of the facts therein stated. If the plaintiff shall finally prevail, he or she shall be allowed a reasonable attorney's fee to be taxed and collected as a part of the costs of the action.
    All complaints for the recovery of damages shall be filed with the Commission within 2 years from the time the produce, commodity or service as to which complaint is made was furnished or performed, and a petition for the enforcement of an order of the Commission for the payment of money shall be filed in the proper court within one year from the date of the order, except that if an appeal is taken from the order of the Commission, the time from the taking of the appeal until its final adjudication shall be excluded in computing the one year allowed for filing the complaint to enforce such order.
    The remedy provided in this section shall be cumulative, and in addition to any other remedy or remedies in this Act provided in case of failure of a public utility to obey a rule, regulation, order or decision of the Commission.

When a customer pays a bill as submitted by a public utility and the billing is later found to be incorrect due to an error either in charging more than the published rate or in measuring the quantity or volume of service provided, the utility shall refund the overcharge with interest from the date of overpayment at the legal rate or at a rate prescribed by rule of the Commission. Refunds and interest for such overcharges may be paid by the utility without the need for a hearing and order of the Commission. Any complaint relating to an incorrect billing must be filed with the Commission no more than 2 years after the date the customer first has knowledge of the incorrect billing.

    Sec. 9‑253. Refunds.
    (a) If the Commission or a court determines that a public utility has overcharged its customers and orders that a refund be made to customers of the utility, a portion of the refund shall be set aside during the refund period or for 120 days after the refund is ordered, whichever is longer, and shall be used to pay refunds to customers who were overcharged and are no longer customers of the utility. The Commission shall determine the amount to be set aside for refunds to former customers. The Commission shall periodically review the appropriateness of the amount of funds set aside for purposes of compensating former customers and make adjustments as needed.
    (b) The utility ordered to make the refund shall notify the public in the form designated by the Commission. In determining the form of the notice, the Commission shall take into account the effectiveness of the format in reaching former customers as well as the administrative costs of notifying past customers.
    (c) A portion of the funds set aside for refunds to former customers may be used to cover administrative costs of the refund. The Commission shall determine the reasonableness of such administrative costs and shall establish a formula for determining how much of the funds may be used for administrative costs.
    (d) Only a former customer who was a customer of the utility during the period of the overcharges and who files a claim with the utility during the refund period or within 120 days after the refund is ordered, whichever is longer, and proves that he was a customer of the utility during the period of overcharges shall be entitled to a refund under this Section. A claim for a refund shall be in writing on a form provided by the utility. For purposes of this Section, "prove" means providing a copy of a past bill for utility services which shows that the claimant was a customer of record of the utility during the period of overcharges. The claimant shall not be obligated to provide a past bill if there is less than 24 months between the date of the refund and the period of the service to which the refund applies.
    (e) If a former customer claims a refund and owes a past due amount to the utility, the refund amount shall be reduced by the amount the customer owes the utility and that past due amount shall be returned to the utility.
    (f) Interest shall accrue on the funds set aside until all moneys have been paid out to customers.
    (g) At the end of the refund period or 120 days after the refund is ordered, whichever is longer, any balance remaining after all legitimate claims for refunds have been paid shall be refunded to current customers of the utility as a credit on their bills.
    (h) The Commission shall determine the formula on how amounts for refunds to former customers shall be calculated.
    (i) This Section does not apply to refunds which were ordered prior to the effective date of this amendatory Act of 1994.
    (j) This Section does not apply to refunds ordered in reconciliation proceedings pursuant to Section 9‑220 of the Public Utilities Act.
