Illinois Compiled Statutes

Information maintained by the Legislative Reference Bureau
Updating the database of the Illinois Compiled Statutes (ILCS) is an ongoing process. Recent laws may not yet be included in the ILCS database, but they are found on this site as Public Acts soon after they become law. For information concerning the relationship between statutes and Public Acts, refer to the Guide.

Because the statute database is maintained primarily for legislative drafting purposes, statutory changes are sometimes included in the statute database before they take effect. If the source note at the end of a Section of the statutes includes a Public Act that has not yet taken effect, the version of the law that is currently in effect may have already been removed from the database and you should refer to that Public Act to see the changes made to the current law.

220 ILCS 5/8-306

    (220 ILCS 5/8-306)
    Sec. 8-306. Special provisions relating to water and sewer utilities.
    (a) No later than 120 days after the effective date of this amendatory Act of the 94th General Assembly, the Commission shall prepare, make available to customers upon request, and post on its Internet web site information concerning the service obligations of water and sewer utilities and remedies that a customer may pursue for a violation of the customer's rights. The information shall specifically address the rights of a customer of a water or sewer utility in the following situations:
        (1) The customer's water meter is replaced.
        (2) The customer's bill increases by more than 50%
    
within one billing period.
        (3) The customer's water service is terminated.
        (4) The customer wishes to complain after receiving
    
a termination of service notice.
        (5) The customer is unable to make payment on a
    
billing statement.
        (6) A rate is filed, including without limitation a
    
surcharge or annual reconciliation filing, that will increase the amount billed to the customer.
        (7) The customer is billed for services provided
    
prior to the date covered by the billing statement.
        (8) The customer is due to receive a credit.
    Each billing statement issued by a water or sewer utility shall include an Internet web site address where the customer can view the information required under this subsection (a) and a telephone number that the customer may call to request a copy of the information.
    (b) A water or sewer utility may discontinue service only after it has mailed or delivered by other means a written notice of discontinuance substantially in the form of Appendix A of 83 Ill. Adm. Code 280. The notice must include the Internet web site address where the customer can view the information required under subsection (a) and a telephone number that the customer may call to request a copy of the information. Any notice required to be delivered or mailed to a customer prior to discontinuance of service shall be delivered or mailed separately from any bill. Service shall not be discontinued until at least 5 days after delivery or 8 days after the mailing of this notice. Service shall not be discontinued and shall be restored if discontinued for the reason which is the subject of a dispute or complaint during the pendency of informal or formal complaint procedures of the Illinois Commerce Commission under 83 Ill. Adm. Code 280.160 or 280.170, where the customer has complied with those rules. Service shall not be discontinued and shall be restored if discontinued where a customer has established a deferred payment agreement pursuant to 83 Ill. Adm. Code 280.110 and has not defaulted on such agreement. Residential customers who are indebted to a utility for past due utility service shall have the opportunity to make arrangements with the utility to retire the debt by periodic payments, referred to as a deferred payment agreement, unless this customer has failed to make payment under such a plan during the past 12 months. The terms and conditions of a reasonable deferred payment agreement shall be determined by the utility after consideration of the following factors, based upon information available from current utility records or provided by the customer or applicant:
        (1) size of the past due account;
        (2) customer or applicant's ability to pay;
        (3) customer or applicant's payment history;
        (4) reason for the outstanding indebtedness;
    
and
        (5) any other relevant factors relating to
    
the circumstances of the customer or applicant's service.
A residential customer shall pay a maximum of one-fourth of the amount past due and owing at the time of entering into the deferred payment agreement, and the water or sewer utility shall allow a minimum of 2 months from the date of the agreement and a maximum of 12 months for payment to be made under a deferred payment agreement. Late payment charges may be assessed against the amount owing that is the subject of a deferred payment agreement.
    (c) A water or sewer utility shall provide notice as required by subsection (a) of Section 9-201 after the filing of each information sheet under a purchased water surcharge, purchased sewage treatment surcharge, or qualifying infrastructure plant surcharge. The utility also shall post notice of the filing in accordance with the requirements of 83 Ill. Adm. Code 255. Unless filed as part of a general rate increase, notice of the filing of a purchased water surcharge rider, purchased sewage treatment surcharge rider, or qualifying infrastructure plant surcharge rider also shall be given in the manner required by this subsection (c) for the filing of information sheets.
    (d) Commission rules pertaining to formal and informal complaints against public utilities shall apply with full and equal force to water and sewer utilities and their customers, including provisions of 83 Ill. Adm. Code 280.170, and the Commission shall respond to each complaint by providing the consumer with a copy of the utility's response to the complaint and a copy of the Commission's review of the complaint and its findings. The Commission shall also provide the consumer with all available options for recourse.
    (e) Any refund shown on the billing statement of a customer of a water or sewer utility must be itemized and must state if the refund is an adjustment or credit.
    (f) Water service for building construction purposes. At the request of any municipality or township within the service area of a public utility that provides water service to customers within the municipality or township, a public utility must (1) require all water service used for building construction purposes to be measured by meter and subject to approved rates and charges for metered water service and (2) prohibit the unauthorized use of water taken from hydrants or service lines installed at construction sites.
    (g) Water meters.
        (1) Periodic testing. Unless otherwise approved by
    
the Commission, each service water meter shall be periodically inspected and tested in accordance with the schedule specified in 83 Ill. Adm. Code 600.340, or more frequently as the results may warrant, to insure that the meter accuracy is maintained within the limits set out in 83 Ill. Adm. Code 600.310.
        (2) Meter tests requested by customer.
            (A) Each utility furnishing metered water
        
service shall, without charge, test the accuracy of any meter upon request by the customer served by such meter, provided that the meter in question has not been tested by the utility or by the Commission within 2 years previous to such request. The customer or his or her representatives shall have the privilege of witnessing the test at the option of the customer. A written report, giving the results of the test, shall be made to the customer.
            (B) When a meter that has been in service less
        
than 2 years since its last test is found to be accurate within the limits specified in 83 Ill. Adm. Code 600.310, the customer shall pay a fee to the utility not to exceed the amounts specified in 83 Ill. Adm. Code 600.350(b). Fees for testing meters not included in this Section or so located that the cost will be out of proportion to the fee specified will be determined by the Commission upon receipt of a complete description of the case.
        (3) Commission referee tests. Upon written
    
application to the Commission by any customer, a test will be made of the customer's meter by a representative of the Commission. For such a test, a fee as provided for in subsection (g)(2) shall accompany the application. If the meter is found to be registering more than 1.5% fast on the average when tested as prescribed in 83 Ill. Adm. Code 600.310, the utility shall refund to the customer the amount of the fee. The utility shall in no way disturb the meter after a customer has made an application for a referee test until authority to do so is given by the Commission or the customer in writing.
    (h) Water and sewer utilities; low usage. Each public utility that provides water and sewer service must establish a unit sewer rate, subject to review by the Commission, that applies only to those customers who use less than 1,000 gallons of water in any billing period.
    (i) Water and sewer utilities; separate meters. Each public utility that provides water and sewer service must offer separate rates for water and sewer service to any commercial or residential customer who uses separate meters to measure each of those services. In order for the separate rate to apply, a combination of meters must be used to measure the amount of water that reaches the sewer system and the amount of water that does not reach the sewer system.
    (j) Each water or sewer public utility must disclose on each billing statement any amount billed that is for service provided prior to the date covered by the billing statement. The disclosure must include the dates for which the prior service is being billed. Each billing statement that includes an amount billed for service provided prior to the date covered by the billing statement must disclose the dates for which that amount is billed and must include a copy of the document created under subsection (a) and a statement of current Commission rules concerning unbilled or misbilled service.
    (k) When the customer is due a refund resulting from payment of an overcharge, the utility shall credit the customer in the amount of overpayment with interest from the date of overpayment by the customer. The rate for interest shall be at the appropriate rate determined by the Commission under 83 Ill. Adm. Code 280.70.
    (l) Water and sewer public utilities; subcontractors. The Commission shall adopt rules for water and sewer public utilities to provide notice to the customers of the proper kind of identification that a subcontractor must present to the customer, to prohibit a subcontractor from soliciting or receiving payment of any kind for any service provided by the water or sewer public utility or the subcontractor, and to establish sanctions for violations.
    (m) Water and sewer public utilities; unaccounted-for water. By December 31, 2006, each water public utility shall file tariffs with the Commission to establish the maximum percentage of unaccounted-for water that would be considered in the determination of any rates or surcharges. The rates or surcharges approved for a water public utility shall not include charges for unaccounted-for water in excess of this maximum percentage without well-documented support and justification for the Commission to consider in any request to recover charges in excess of the tariffed maximum percentage.
    (n) Rate increases; public forums. When any public utility providing water or sewer service proposes a general rate increase, in addition to other notice requirements, the water or sewer public utility must notify its customers of their right to request a public forum. A customer or group of customers must make written request to the Commission for a public forum and must also provide written notification of the request to the customer's municipal or, for unincorporated areas, township government. The Commission, at its discretion, may schedule the public forum. If it is determined that public forums are required for multiple municipalities or townships, the Commission shall schedule these public forums, in locations within approximately 45 minutes drive time of the municipalities or townships for which the public forums have been scheduled. The public utility must provide advance notice of 30 days for each public forum to the governing bodies of those units of local government affected by the increase. The day of each public forum shall be selected so as to encourage the greatest public participation. Each public forum will begin at 7:00 p.m. Reports and comments made during or as a result of each public forum must be made available to the hearing officials and reviewed when drafting a recommended or tentative decision, finding or order pursuant to Section 10-111 of this Act.

220 ILCS 5/8-402.2

    (220 ILCS 5/8-402.2)
    Sec. 8-402.2. Public Schools Carbon-Free Assessment programs.
    (a) Within one year after the effective date of this amendatory Act of the 102nd General Assembly, each electric utility serving over 500,000 retail customers in this State shall implement a Public Schools Carbon-Free Assessment program.
    (b) Each utility's Public Schools Carbon-Free Assessment program shall include the following requirements:
        (1) Each plan shall be designed to offer within the
    
utility's service territory to assist public schools, as defined by Section 1-3 of the School Code, to increase the efficiency of their energy usage, to reduce the carbon emissions associated with their energy usage, and to move toward a goal of public schools being carbon-free in their energy usage by 2030. The program shall include a target of completing Public Schools Carbon-Free Assessment for all public schools in the utility's service territory by December 31, 2029.
        (2) The Public Schools Carbon-Free Assessment shall
    
be a generally standardized assessment, but may incorporate flexibility to reflect the circumstances of individual public schools and public school districts.
        (3) The Public Schools Carbon-Free Assessment shall
    
include, but not be limited to, comprehensive analyses of the following subjects:
            (A) The top energy efficiency savings
        
opportunities for the public school, by energy saved;
            (B) The total achievable solar energy potential
        
on or nearby a public school's premises and able to provide power to a school;
            (C) The infrastructure required to support
        
electrification of the facility's space heating and water heating needs;
            (D) The infrastructure requirements to support
        
electrification of a school's transportation needs; and
            (E) The investments required to achieve a WELL
        
Certification or similar certification as determined through methods developed and updated by the International WELL Building Institute or similar or successor organizations.
        (4) The Public Schools Carbon-Free Assessment also
    
shall include, but not be limited to, mechanical insulation evaluation inspection and inspection of the building envelope(s).
        (5) With respect to those public school
    
construction projects for public schools within the service territory of a utility serving over 500,000 retail customers in this State and for which a public school district applies for a grant under Section 5-40 of the School Construction Law on or after June 1, 2023, the district must submit a copy of the applicable Public Schools Carbon-Free Assessment report, or, if no such Public Schools Carbon-Free Assessment has been performed, request the applicable utility to perform such a Public Schools Carbon-Free Assessment and submit a copy of the Public Schools Carbon-Free Assessment report promptly when it becomes available. The Public Schools Carbon-Free Assessment report shall include, but not limited to, an energy audit of both the building envelope and the building's mechanical insulation system. It shall also include an inspection of both the building envelope and the mechanical insulation system. The district must demonstrate how the construction project is designed and managed to achieve the goals that all public elementary and secondary school facilities in the State are able to be powered by clean energy by 2030, and for such facilities to achieve carbon-free energy sources for space heat, water heat, and transportation by 2050.
        (6) The results of each Public Schools
    
Carbon-Free Assessment shall be memorialized by the utility or by a third party acting on behalf of the utility in a non-confidential report form that includes recommendations and redacts all confidential information and shall be provided to the applicable public school.

The Illinois Power Agency shall promptly make the results of each non-confidential report available for public inspection on its website.
        (7) The Public Schools Carbon-Free Assessment
    
shall be conducted in coordination with each utility's energy efficiency and demand-response plans under Sections 8-103, 8-103A, and 8-103B of this Act, to the extent applicable. Nothing in this Section is intended to modify or require modification of those plans. However, the utility may request a modification of a plan approved by the Commission, and the Commission may approve the requested modification, if the modification is consistent with the provisions of this Section and Section 8-103B of this Act.
        (8) If there are no other providers of assessments
    
that are substantively the same as those being performed by utilities pursuant to this Section by 2024, a utility that has a Public Schools Carbon-Free Assessment program may offer assessments to public schools that are not served by a utility subject to this Section at the utility's cost.
        (9) The Public Schools Carbon-Free Assessment shall
    
be offered to and performed for public schools in the utility's service territory on a complimentary basis by each utility, with no Assessment fee charged to the public schools for the Assessments. Nothing in this Section is intended to prohibit the utility from recovering through rates approved by the Commission the utility's prudent and reasonable costs of complying with this Section.
        (10) Utilities shall make efforts to prioritize the
    
completion of Public Schools Carbon-Free Assessments for the following school districts by December 31, 2022: East St. Louis School District 189, Harvey School District 152, Thornton Township High School District 205.

220 ILCS 5/8-403

    (220 ILCS 5/8-403) (from Ch. 111 2/3, par. 8-403)
    Sec. 8-403. The Commission shall design and implement policies which encourage the economical utilization of cogeneration and small power production, as these terms are defined in Section 3-105, item (7) of subsection (b), including specifically, but not limited to, the cogeneration or production of heat, steam or electricity by municipal corporations or any other political subdivision of this State. No public utility shall discriminate in any way with respect to the conditions or price for provision of maintenance power, standby power and supplementary power as these terms are defined by current Commission rules, or for any other service. The prices charged by a utility for maintenance power, standby power, supplementary power and all other such services shall be cost-based and just and reasonable.
    The Commission shall conduct a study of procedures and policies to encourage the full and economical utilization of cogeneration and small power production including, but not limited to, (1) requiring utilities to pay full avoided costs, including long-term avoided capacity costs to cogenerators and small power producers and (2) requiring utilities to make available upon request of the State or a unit of local government, transmission and distribution services to transmit electrical energy produced by cogeneration or small power production facilities located in any structure or on any real property of the State or unit of local government to other locations of this State or a unit of local government. The Commission shall report on this study, with recommendation for legislative consideration, to the General Assembly by March 1, 1986.

220 ILCS 5/8-403.1

    (220 ILCS 5/8-403.1) (from Ch. 111 2/3, par. 8-403.1)
    Sec. 8-403.1. Electricity purchased from qualified solid waste energy facility; tax credit; distributions for economic development.
    (a) It is hereby declared to be the policy of this State to encourage the development of alternate energy production facilities in order to conserve our energy resources and to provide for their most efficient use.
    (b) For the purpose of this Section and Section 9-215.1, "qualified solid waste energy facility" means a facility determined by the Illinois Commerce Commission to qualify as such under the Local Solid Waste Disposal Act, to use methane gas generated from landfills as its primary fuel, and to possess characteristics that would enable it to qualify as a cogeneration or small power production facility under federal law.
    (c) In furtherance of the policy declared in this Section, the Illinois Commerce Commission shall require electric utilities to enter into long-term contracts to purchase electricity from qualified solid waste energy facilities located in the electric utility's service area, for a period beginning on the date that the facility begins generating electricity and having a duration of not less than 10 years in the case of facilities fueled by landfill-generated methane, or 20 years in the case of facilities fueled by methane generated from a landfill owned by a forest preserve district. The purchase rate contained in such contracts shall be equal to the average amount per kilowatt-hour paid from time to time by the unit or units of local government in which the electricity generating facilities are located, excluding amounts paid for street lighting and pumping service.
    (d) Whenever a public utility is required to purchase electricity pursuant to subsection (c) above, it shall be entitled to credits in respect of its obligations to remit to the State taxes it has collected under the Electricity Excise Tax Law equal to the amounts, if any, by which payments for such electricity exceed (i) the then current rate at which the utility must purchase the output of qualified facilities pursuant to the federal Public Utility Regulatory Policies Act of 1978, less (ii) any costs, expenses, losses, damages or other amounts incurred by the utility, or for which it becomes liable, arising out of its failure to obtain such electricity from such other sources. The amount of any such credit shall, in the first instance, be determined by the utility, which shall make a monthly report of such credits to the Illinois Commerce Commission and, on its monthly tax return, to the Illinois Department of Revenue. Under no circumstances shall a utility be required to purchase electricity from a qualified solid waste energy facility at the rate prescribed in subsection (c) of this Section if such purchase would result in estimated tax credits that exceed, on a monthly basis, the utility's estimated obligation to remit to the State taxes it has collected under the Electricity Excise Tax Law. The owner or operator shall negotiate facility operating conditions with the purchasing utility in accordance with that utility's posted standard terms and conditions for small power producers. If the Department of Revenue disputes the amount of any such credit, such dispute shall be decided by the Illinois Commerce Commission. Whenever a qualified solid waste energy facility has paid or otherwise satisfied in full the capital costs or indebtedness incurred in developing and implementing the qualified solid waste energy facility, whenever the qualified solid waste energy facility ceases to operate and produce electricity from methane gas generated from landfills, or at the end of the contract entered into pursuant to subsection (c) of this Section, whichever occurs first, the qualified solid waste energy facility shall reimburse the Public Utility Fund and the General Revenue Fund in the State treasury for the actual reduction in payments to those Funds caused by this subsection (d) in a manner to be determined by the Illinois Commerce Commission and based on the manner in which revenues for those Funds were reduced. The payments shall be made to the Illinois Commerce Commission, which shall determine the appropriate disbursements to the Public Utility Fund and the General Revenue Fund based on this subsection (d).
    (e) The Illinois Commerce Commission shall not require an electric utility to purchase electricity from any qualified solid waste energy facility which is owned or operated by an entity that is primarily engaged in the business of producing or selling electricity, gas, or useful thermal energy from a source other than one or more qualified solid waste energy facilities.
    (e-5) A qualified solid waste energy facility may receive the purchase rate provided in subsection (c) of this Section only for kilowatt-hours generated by the use of methane gas generated from landfills. The purchase rate provided in subsection (c) of this Section does not apply to electricity generated by the use of a fuel that is not methane gas generated from landfills. If the Illinois Commerce Commission determines that a qualified solid waste energy facility has violated the requirement regarding the use of methane gas generated from a landfill as set forth in this subsection (e-5), then the Commission shall issue an order requiring that the qualified solid waste energy facility repay the State for all dollar amounts of electricity sales that are determined by the Commission to be the result of the violation. As part of that order, the Commission shall have the authority to revoke the facility's approval to act as a qualified solid waste energy facility granted by the Commission under this Section. If the amount owed by the qualified solid waste energy facility is not received by the Commission within 90 days after the date of the Commission's order that requires repayment, then the Commission shall issue an order that revokes the facility's approval to act as a qualified solid waste energy facility granted by the Commission under this Section. The Commission's action that vacates prior qualified solid waste energy facility approval does not excuse the repayment to the State treasury required by subsection (d) of this Section for utility tax credits accumulated up to the time of the Commission's action. A qualified solid waste energy facility must receive Commission approval before it may use any fuel in addition to methane gas generated from a landfill in order to generate electricity. If a qualified solid waste energy facility petitions the Commission to use any fuel in addition to methane gas generated from a landfill to generate electricity, then the Commission shall have the authority to do the following:
        (1) establish the methodology for determining the
    
amount of electricity that is generated by the use of methane gas generated from a landfill and the amount that is generated by the use of other fuel;
        (2) determine all reporting requirements for the
    
qualified solid waste energy facility that are necessary for the Commission to determine the amount of electricity that is generated by the use of methane gas from a landfill and the amount that is generated by the use of other fuel and the resulting payments to the qualified solid waste energy facility; and
        (3) require that the qualified solid waste energy
    
facility, at the qualified solid waste energy facility's expense, install metering equipment that the Commission determines is necessary to enforce compliance with this subsection (e-5).
    A public utility that is required to enter into a long-term purchase contract with a qualified solid waste energy facility has no duty to determine whether the electricity being purchased was generated by the use of methane gas generated from a landfill or was generated by the use of some other fuel in violation of the requirements of this subsection (e-5).
    (f) This Section does not require an electric utility to construct additional facilities unless those facilities are paid for by the owner or operator of the affected qualified solid waste energy facility.
    (g) The Illinois Commerce Commission shall require that: (1) electric utilities use the electricity purchased from a qualified solid waste energy facility to displace electricity generated from nuclear power or coal mined and purchased outside the boundaries of the State of Illinois before displacing electricity generated from coal mined and purchased within the State of Illinois, to the extent possible, and (2) electric utilities report annually to the Commission on the extent of such displacements.
    (h) Nothing in this Section is intended to cause an electric utility that is required to purchase power hereunder to incur any economic loss as a result of its purchase. All amounts paid for power which a utility is required to purchase pursuant to subparagraph (c) shall be deemed to be costs prudently incurred for purposes of computing charges under rates authorized by Section 9-220 of this Act. Tax credits provided for herein shall be reflected in charges made pursuant to rates so authorized to the extent such credits are based upon a cost which is also reflected in such charges.
    (i) Beginning in February 1999 and through January 2013, each qualified solid waste energy facility that sells electricity to an electric utility at the purchase rate described in subsection (c) shall file with the Department of Revenue on or before the 15th of each month a form, prescribed by the Department of Revenue, that states the number of kilowatt hours of electricity for which payment was received at that purchase rate from electric utilities in Illinois during the immediately preceding month. This form shall be accompanied by a payment from the qualified solid waste energy facility in an amount equal to six-tenths of a mill ($0.0006) per kilowatt hour of electricity stated on the form. Beginning on the effective date of this amendatory Act of the 92nd General Assembly, a qualified solid waste energy facility must file the form required under this subsection (i) before the 15th of each month regardless of whether the facility received any payment in the previous month. Payments received by the Department of Revenue shall be deposited into the Municipal Economic Development Fund, a trust fund created outside the State treasury. The State Treasurer may invest the moneys in the Fund in any investment authorized by the Public Funds Investment Act, and investment income shall be deposited into and become part of the Fund. Moneys in the Fund shall be used by the State Treasurer as provided in subsection (j).
    Beginning on July 1, 2006 through January 31, 2013, each month the State Treasurer shall certify the following to the State Comptroller:
        (A) the amount received by the Department of Revenue
    
under this subsection (i) during the immediately preceding month; and
        (B) the amount received by the Department of Revenue
    
under this subsection (i) in the corresponding month in calendar year 2002.
As soon as practicable after receiving the certification from the State Treasurer, the State Comptroller shall transfer from the General Revenue Fund to the Municipal Economic Development Fund in the State treasury an amount equal to the amount by which the amount calculated under item (B) of this paragraph exceeds the amount calculated under item (A) of this paragraph, if any.
    The obligation of a qualified solid waste energy facility to make payments into the Municipal Economic Development Fund shall terminate upon either: (1) expiration or termination of a facility's contract to sell electricity to an electric utility at the purchase rate described in subsection (c); or (2) entry of an enforceable, final, and non-appealable order by a court of competent jurisdiction that Public Act 89-448 is invalid. Payments by a qualified solid waste energy facility into the Municipal Economic Development Fund do not relieve the qualified solid waste energy facility of its obligation to reimburse the Public Utility Fund and the General Revenue Fund for the actual reduction in payments to those Funds as a result of credits received by electric utilities under subsection (d).
    A qualified solid waste energy facility that fails to timely file the requisite form and payment as required by this subsection (i) shall be subject to penalties and interest in conformance with the provisions of the Illinois Uniform Penalty and Interest Act.
    Every qualified solid waste energy facility subject to the provisions of this subsection (i) shall keep and maintain records and books of its sales pursuant to subsection (c), including payments received from those sales and the corresponding tax payments made in accordance with this subsection (i), and for purposes of enforcement of this subsection (i) all such books and records shall be subject to inspection by the Department of Revenue or its duly authorized agents or employees.
    When a qualified solid waste energy facility fails to file the form or make the payment required under this subsection (i), the Department of Revenue, to the extent that it is practical, may enforce the payment obligation in a manner consistent with Section 5 of the Retailers' Occupation Tax Act, and if necessary may impose and enforce a tax lien in a manner consistent with Sections 5a, 5b, 5c, 5d, 5e, 5f, 5g, and 5i of the Retailers' Occupation Tax Act. No tax lien may be imposed or enforced, however, unless a qualified solid waste energy facility fails to make the payment required under this subsection (i). Only to the extent necessary and for the purpose of enforcing this subsection (i), the Department of Revenue may secure necessary information from a qualified solid waste energy facility in a manner consistent with Section 10 of the Retailers' Occupation Tax Act.
    All information received by the Department of Revenue in its administration and enforcement of this subsection (i) shall be confidential in a manner consistent with Section 11 of the Retailers' Occupation Tax Act. The Department of Revenue may adopt rules to implement the provisions of this subsection (i).
    For purposes of implementing the maximum aggregate distribution provisions in subsections (j) and (k), when a qualified solid waste energy facility makes a late payment to the Department of Revenue for deposit into the Municipal Economic Development Fund, that payment and deposit shall be attributed to the month and corresponding quarter in which the payment should have been made, and the Treasurer shall make retroactive distributions or refunds, as the case may be, whenever such late payments so require.
    (j) The State Treasurer, without appropriation, must make distributions immediately after January 15, April 15, July 15, and October 15 of each year, up to maximum aggregate distributions of $500,000 for the distributions made in the 4 quarters beginning with the April distribution and ending with the January distribution, from the Municipal Economic Development Fund to each city, village, or incorporated town located in Cook County that has approved construction within its boundaries of an incinerator that will burn recovered wood processed for fuel to generate electricity and will commence operation after 2009. Total distributions in the aggregate to all qualified cities, villages, and incorporated towns in the 4 quarters beginning with the April distribution and ending with the January distribution shall not exceed $500,000. The amount of each distribution shall be determined pro rata based on the population of the city, village, or incorporated town compared to the total population of all cities, villages, and incorporated towns eligible to receive a distribution. Distributions received by a city, village, or incorporated town must be held in a separate account and may be used only to promote and enhance industrial, commercial, residential, service, transportation, and recreational activities and facilities within its boundaries, thereby enhancing the employment opportunities, public health and general welfare, and economic development within the community, including administrative expenditures exclusively to further these activities. Distributions may also be used for cleanup of open dumping from vacant properties and the removal of structures condemned by the city, village, or incorporated town. These funds, however, shall not be used by the city, village, or incorporated town, directly or indirectly, to purchase, lease, operate, or in any way subsidize the operation of any incinerator, and these funds shall not be paid, directly or indirectly, by the city, village, or incorporated town to the owner, operator, lessee, shareholder, or bondholder of any incinerator. Moreover, these funds shall not be used to pay attorneys fees in any litigation relating to the validity of Public Act 89-448. Nothing in this Section prevents a city, village, or incorporated town from using other corporate funds for any legitimate purpose. For purposes of this subsection, the term "municipal waste" has the meaning ascribed to it in Section 3.290 of the Environmental Protection Act.
    (k) If maximum aggregate distributions of $500,000 under subsection (j) have been made after the January distribution from the Municipal Economic Development Fund, then the balance in the Fund shall be refunded to the qualified solid waste energy facilities that made payments that were deposited into the Fund during the previous 12-month period. The refunds shall be prorated based upon the facility's payments in relation to total payments for that 12-month period.
    (l) Beginning January 1, 2000, and each January 1 thereafter, each city, village, or incorporated town that received distributions from the Municipal Economic Development Fund, continued to hold any of those distributions, or made expenditures from those distributions during the immediately preceding year shall submit to a financial and compliance and program audit of those distributions performed by the Auditor General at no cost to the city, village, or incorporated town that received the distributions. The audit should be completed by June 30 or as soon thereafter as possible. The audit shall be submitted to the State Treasurer and those officers enumerated in Section 3-14 of the Illinois State Auditing Act. If the Auditor General finds that distributions have been expended in violation of this Section, the Auditor General shall refer the matter to the Attorney General. The Attorney General may recover, in a civil action, 3 times the amount of any distributions illegally expended. For purposes of this subsection, the terms "financial audit," "compliance audit", and "program audit" have the meanings ascribed to them in Sections 1-13 and 1-15 of the Illinois State Auditing Act.
    (m) On and after the effective date of this amendatory Act of the 94th General Assembly, beginning on the first date on which renewable energy certificates or other saleable representations are sold by a qualified solid waste energy facility, with or without the electricity generated by the facility, and utilized by an electric utility or another electric supplier to comply with a renewable energy portfolio standard mandated by Illinois law or mandated by order of the Illinois Commerce Commission, that qualified solid waste energy facility may not sell electricity pursuant to this Section and shall be exempt from the requirements of subsections (a) through (l) of this Section, except that it shall remain obligated for any reimbursements required under subsection (d) of this Section. All of the provisions of this Section shall remain in full force and effect with respect to any qualified solid waste energy facility that sold electric energy pursuant to this Section at any time before July 1, 2006 and that does not sell renewable energy certificates or other saleable representations to meet the requirements of a renewable energy portfolio standard mandated by Illinois law or mandated by order of the Illinois Commerce Commission.
    (n) Notwithstanding any other provision of law to the contrary, beginning on July 1, 2006, the Illinois Commerce Commission shall not issue any order determining that a facility is a qualified solid waste energy facility unless the qualified solid waste energy facility was determined by the Illinois Commerce Commission to be a qualified solid waste energy facility before July 1, 2006. As a guide to the intent, interpretation, and application of this amendatory Act of the 94th General Assembly, it is hereby declared to be the policy of this State to honor each qualified solid waste energy facility contract in existence on the effective date of this amendatory Act of the 94th General Assembly if the qualified solid waste energy facility continues to meet the requirements of this Section for the duration of its respective contract term.

    Sec. 8-407. (a) The Commission, after granting any certificate of public convenience and necessity for the construction of a new electric generating facility, shall reevaluate the propriety and necessity for the certificate at least every 3 years and shall consider in the reevaluation any and all changes in the forecasts and circumstances relied upon in its initial decision to grant the certificate, including but not limited to, each criterion that is outlined in this Section as a precondition for the granting of a certificate and any changes in the energy plans for the utility and the State.
    (b) Whenever the Commission grants any certificate of public convenience and necessity for the construction of a new electric generating facility, the Commission shall design and establish all procedures necessary for it to thoroughly and effectively evaluate, supervise, and monitor construction, and shall thereafter take all steps necessary to assure that construction is efficient and economical.
    The Commission shall have the power to conduct a construction cost audit at any time during construction, or to arrange for such an audit to be conducted by persons independent of the utility and selected by the Commission, whenever the Commission has cause to believe that such audit is necessary, or likely to be beneficial, to the efficiency or economy of construction. 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 pursuant to this Act.
    (c) The Commission shall have the power to withdraw or alter any certificate of public convenience and necessity including any certificate granted for the construction of a new electric generating facility or a substantial alteration or addition to an existing generating facility where it determines that:
        (i) circumstances have changed so substantially that
    
continued construction is no longer necessary or beneficial to ratepayers; or
        (ii) the utility has failed to substantially comply
    
with the requirements and conditions of its certificate or subsequent Commission orders with respect to the construction process.

    Sec. 8-408. Energy efficiency plans for small multi-jurisdictional utilities.
    (a) Any electric or gas public utility with fewer than 200,000 customers in Illinois on January 1, 2007 that offers energy efficiency programs to its customers in a state adjacent to Illinois may seek the approval of the Commission to offer the same or comparable energy efficiency programs to its customers in Illinois. For each program to be offered, the utility shall submit to the Commission:
        (1) a description of the program;
        (2) a proposed implementation schedule and method;
        (3) the number of eligible participants;
        (4) the expected rate of participation per year;
        (5) the estimated annual peak demand and energy
    
savings;
        (6) the budget or level of spending; and
        (7) the rate impacts and average bill impacts, by
    
customer class, resulting from the program.
    The Commission shall approve each program demonstrated to be cost-effective. Programs for low-income customers shall be approved by the Commission even if they have not been demonstrated to be cost-effective if they are demonstrated to be reasonable. An order of the State agency that regulates the rates of the utility in the adjacent state that finds a program to be cost-effective or reasonable shall be sufficient to demonstrate that the program is cost-effective or reasonable for the utility's customers in Illinois. Approved programs may be delivered by the utility or by a contractor or agent of the utility.
    (b) Notwithstanding the provisions of Section 9-201, a public utility providing approved energy efficiency programs in the State shall be permitted to recover the reasonable costs of those programs through an automatic adjustment clause tariff filed with and approved by the Commission. Each year the Commission shall initiate a review to reconcile any amounts collected with the actual costs and to determine the adjustment to the annual tariff factor to match annual expenditures. The determination shall be made within 90 days after the date of initiation of the review.
    (c) The utility may request a waiver of one or more components of an approved energy efficiency program at any time in order to improve the program's effectiveness. The Commission may grant the waiver if good cause is shown by the utility. Notwithstanding the cessation of the programs, a utility shall file a final reconciliation of the amounts collected as compared to the actual costs and shall continue the resulting factor until any over-recovery or under-recovery approaches zero.
    (d) A public utility that offers approved energy efficiency programs in the State may do so through at least December 31, 2012. The Commission shall monitor the performance of the energy efficiency programs and, on or before October 31, 2012, the Commission shall make a determination regarding whether the programs should be continued beyond calendar year 2012. The Commission shall also file a written report with the General Assembly explaining the basis for that determination and detailing the results of the energy efficiency programs, including energy savings, participation numbers, and costs.

        (2) Provide direct notice of vegetation management
    
activities no less than 21 days nor more than 90 days before the activities begin.
            (A) If the vegetation management activities will
        
occur in an incorporated municipality, the notice must be given to the mayor or his or her designee.
            (B) If the vegetation management activities will
        
occur in an unincorporated area, the notice must be given to the chairman of the county board or his or her designee.
            (C) Affected customers shall be notified directly.
            (D) Affected property owners shall be notified by
        
a published notice in a newspaper or newspapers in general circulation and widely distributed within the entire area in which the vegetation management activities notice will occur.
            (E) Circuit maps or a description by common
        
address of the area to be affected by vegetation management activities must accompany any notice to a mayor or his or her designee or to a chairman of a county board or his or her designee.
        The electric public utility giving the direct and
    
published notices required in this subsection (a)(2) shall provide notified customers and property owners with (i) a statement of the vegetation management activities planned, (ii) the address of a website and a toll-free telephone number at which a written disclosure of all dispute resolution opportunities and processes, rights, and remedies provided by the electric public utility may be obtained, (iii) a statement that the customer and the property owner may appeal the planned vegetation management activities through the electric public utility and the Illinois Commerce Commission, (iv) a toll-free telephone number through which communication may be had with a representative of the electric public utility regarding the vegetation management activities, and (v) the telephone number of the Consumer Affairs Officer of the Illinois Commerce Commission. The notice shall also include a statement that circuit maps and common addresses of the area to be affected by the vegetation management activities are on file with the office of the mayor of an affected municipality or his or her designee and the office of the county board chairman of an affected county or his or her designee.
    The Commission shall have sole authority to investigate, issue, and hear complaints against the utility under this subsection (a).

    (c) A public utility shall not be required to comply with the requirements of subsection (a) or (d) if there is a franchise, contract, or written agreement between the public utility and the municipality or county mandating specific vegetation management practices. If the franchise, contract, or written agreement between the public utility and the municipality or county establishes requirements for notice to the municipality, county, customers, and property owners, those notice requirements shall control over the notice requirements of paragraph (2) of subsection (a). If the franchise, contract, or written agreement between the public utility and the municipality or county does not establish notice requirements, the notice requirements contained in paragraph (2) of subsection (a) shall control.
    (d) If no franchise, contract, or written agreement between a utility and a municipality mandates a specific vegetation management practice and the municipality enacts an ordinance establishing standards for non-emergency vegetation management practices that are contrary to the standards established by this Section and the vegetation management activities of the electric public utility cost substantially more, as a direct consequence, then the electric public utility may, before vegetation management activities begin, apply to the municipality for an agreement to pay the additional cost. When an application for an agreement is made to the municipality, no vegetation management activities shall begin until the municipality responds to the application by agreement or rejection or dispute resolution proceedings are completed. The application shall be supported by a detailed specification of the difference between the standards established by this Section and the contrary standards established by the municipal ordinances and by a good faith bid or proposal obtained from a utility contractor or contractors quantifying the additional cost for performing the specification. When the municipality receives the specification and the utility contractor's bid or proposal, the municipality shall agree, reject, or initiate dispute resolution proceedings regarding the application within 90 days after the application's receipt. If the municipality does not act within 90 days or informs the utility that it will not agree, the electric public utility may proceed and need not comply with the contrary ordinance standard. When there is a dispute regarding (i) the accuracy of the specification, (ii) whether there is a conflict with the standards established by this Section, or (iii) any aspect of the bid or proposal process, the Illinois Commerce Commission shall hear and resolve the disputed matter or matters, with the electric public utility having the burden of proof. A municipality may have a person trained in tree care and maintenance generally monitor and discuss with the vegetation management supervisory personnel of the electric public utility the performance of the public utility's vegetation management activities without any claim for costs hereunder by the public utility arising therefrom.
    The provisions of this Section shall not in any way diminish or replace other civil or administrative remedies available to a customer or class of customers or a property owner or class of property owners under this Act. This Section does not alter the jurisdiction of the Illinois Commerce Commission in any manner except to obligate the Commission to investigate, issue, and hear complaints against an electric public utility as provided in subsection (a)(2) and to hear and resolve disputed matters brought to it as provided in this subsection. Vegetation management activities by an electric public utility shall not alter, trespass upon, or limit the rights of any property owner.

    (220 ILCS 5/8-508) (from Ch. 111 2/3, par. 8-508)
    Sec. 8-508. No public utility shall abandon or discontinue any service or, in the case of an electric utility, make any modification as herein defined, without first having secured the approval of the Commission, except in case of assignment, transfer, lease or sale of the whole or any part of its franchises, licenses, permits, plant, equipment, business, or other property to any political subdivision or municipal corporation of this State. In the case of the assignment, transfer, lease or sale, in whole or in part, of any franchise, license, permit, plant, equipment, business or other property to any political subdivision or municipal corporation of this State, the public utility shall notify the Commission of such transaction. "Modification" as used in this Section means any change of fuel type which would result in an annual net systemwide decreased use of 10% or more of coal mined in Illinois. The Commission shall conduct public hearings on any request by a public utility to make such modification and shall accept testimony from interested parties qualified to provide evidence regarding the cost or cost savings of the proposed modification as compared with the cost or cost savings of alternative actions by the utility and shall consider the impact on employment related to the production of coal in Illinois. Such hearings shall be commenced no later than 30 days after the filing of the request by the public utility and shall be concluded within 120 days from the date of filing. The Commission must issue its final determination within 60 days of the conclusion of the hearing. In making its determination the Commission shall attach primary weight to the cost or cost savings to the customers of the utility. In granting its approval, the Commission may impose such terms, conditions or requirements as in its judgment are necessary to protect the public interest. Provided, however, that any public utility abandoning or discontinuing service in pursuance of authority granted by the Commission shall be deemed to have waived any and all objections to the terms, conditions or requirements imposed by the Commission in that regard. Provided, further, that nothing in this Section shall be construed to limit the right of a public utility to discontinue service to individual patrons in accordance with the effective rules, regulations, and practices of such public utility.
    The Commission, after a hearing upon its own motion or upon petition of any public utility, shall have power by order to authorize or require any public utility to curtail or discontinue service to individual customers or classes thereof, or for specific purposes or uses, and otherwise to regulate the furnishing of service, provided that preference for service shall be given to those customers serving essential human needs and governmental agencies performing law enforcement functions, whenever and to the extent such action is required by the convenience and necessity of the public during time of war, invasion, insurrection or martial law, or by reason of a catastrophe, emergency, or shortage of fuel, supplies or equipment employed or service furnished by such public utility; provided, however, that an interim order, effective for a period not exceeding 45 days, may be made without a hearing if the circumstances do not reasonably permit the holding of a hearing. Orders for the curtailment or discontinuance of service pursuant to this paragraph shall not be continued in effect for any period beyond that which is reasonably necessary, shall be vacated by the Commission as soon as public convenience and necessity permit, and shall include such arrangements for substitute service in the interim as the Commission in its judgment may impose. Every such order, during the period it is in effect and for such further period, if any, as the Commission may provide, shall have the effect of suspending the operation of all prior orders or parts of orders of the Commission inconsistent therewith. No public utility shall be held liable for any damage resulting from any action taken, or any omission to act, pursuant to or in compliance with any order under this paragraph for the curtailment or discontinuance of service unless such order was procured by the fraud of the public utility.

    (220 ILCS 5/8-508.1) (from Ch. 111 2/3, par. 8-508.1)
    Sec. 8-508.1. (a) As used in this Section:
        (1) "Decommissioning" means the series of activities
    
undertaken at the time a nuclear power plant is permanently retired from service to ensure that the final entombment, decontamination, dismantlement, removal and disposal of the plant, including the plant site, and of any radioactive components and materials associated with the plant, is accomplished in compliance with all applicable Illinois and federal laws, and to ensure that such final disposition does not pose any threat to the public health and safety.
        (2) "Decommissioning costs" means all reasonable
    
costs and expenses incurred in connection with the entombment, decontamination, dismantlement, removal and disposal of the structures, systems and components of a nuclear power plant at the time of decommissioning, including all expenses to be incurred in connection with the preparation for decommissioning, such as engineering and other planning expenses, and to be incurred after the actual decommissioning occurs, such as physical security and radiation monitoring expenses, less proceeds of insurance, salvage or resale of machinery, construction equipment or apparatus the cost of which was charged as a decommissioning expense.
        (3) "Decommissioning trust" or "trust" means a
    
fiduciary account in a bank or other financial institution established to hold the decommissioning funds provided pursuant to subsection (b)(2) of this Section for the eventual purpose of paying decommissioning costs, which shall be separate from all other accounts and assets of the public utility establishing the trust.
        (4) "Nuclear power plant" or "plant" means a nuclear
    
fission thermal power plant. Each unit of a multi-unit site shall be considered a separate plant.
    (b) By 90 days after the effective date of this amendatory Act of 1988, or by the date that the unit satisfies the criteria used by the Internal Revenue Service for determining when depreciation commences for federal income tax purposes on a new generating unit, whichever is later, every public utility that owns or operates, in whole or in part, a nuclear power plant shall:
        (1) establish 2 decommissioning trusts, which shall
    
be a "tax qualified" decommissioning trust and a "non-tax qualified" decommissioning trust and shall hold the decommissioning funds established by the public utility for all nuclear power plants pursuant to subsection (b)(2) of this Section;
        (2) establish 2 decommissioning funds for each such
    
plant, each of which shall be held for a plant as a separate account in a decommissioning trust; and
        (3) designate an independent trustee, subject to the
    
approval of the Commission, to administer each of the decommissioning trusts.
    (c) The 2 decommissioning trusts shall be known as the "tax qualified" decommissioning trust and the "non-tax qualified" decommissioning trust respectively. Each trust shall be established and maintained as follows:
        (1) The "tax qualified" trust shall be established
    
and maintained in accordance with Section 468A of the Internal Revenue Code of 1986 or any successor thereto and shall be funded by the public utility for each such power plant through annual payments by the public utility that shall not exceed the maximum amount allowable as a deduction for federal income tax purposes for the year for which the payments were made, in accordance with Section 468A of the Internal Revenue Code of 1986 or any successor thereto.
        (2) The "non-tax qualified" decommissioning trust
    
shall be funded by the public utility for each such power plant through annual payments by the public utility that shall consist of the difference between the total amounts of decommissioning expenses collected after the effective date of this amendatory Act of 1988 through rates and charges from the public utility's customers as provided by the Commission minus the amounts contributed to the "tax qualified" trust as provided by subsection (c)(1) of this Section and deductible for federal income tax purposes in accordance with Section 468A of the Internal Revenue Code of 1986 or any successor thereto.
        (3) The following restrictions shall apply in regard
    
to administration of each decommissioning trust:
            (i) Distributions may be made from a nuclear
        
decommissioning trust only to satisfy the liabilities of the public utility for nuclear decommissioning costs relating to the nuclear power plant for which the decommissioning fund was established and to pay administrative costs, income taxes and other incidental expenses of the trust.
            (ii) Any assets in a nuclear decommissioning
        
trust that exceed the amount necessary to pay the nuclear decommissioning costs of the nuclear power plant for which the decommissioning fund was established shall be refunded to the public utility that established the fund for the purpose of refunds or credits, as soon as practicable, to the utility's customers.
            (iii) In the event a public utility sells or
        
otherwise disposes of its direct ownership interest, or any part thereof, in a nuclear power plant with respect to which a nuclear decommissioning fund has been established, the assets of the fund shall be distributed to the public utility to the extent of the reductions in its liability for future decommissioning after taking into account the liabilities of the public utility for future decommissioning of such nuclear power plant and the liabilities that have been assumed by another entity. The public utility shall, as soon as practicable, provide refunds or credits to its customers representing the full amount of the reductions in its liability for future decommissioning.
            (iv) The trustee shall invest the "tax qualified"
        
trust assets only in secure assets that are prudent investments for assets held in trust and in such a way as to attempt to maximize the after-tax return on funds invested, subject to the limitations specified in Section 468A of the Internal Revenue Code of 1986 or any successor thereto.
            (v) The trustee shall invest the "non-tax
        
qualified" trust assets only in secure assets that are prudent investments for assets held in trust and in such a way as to attempt to maximize the after-tax return on funds invested. However the trustee shall not invest any portion of the "non-tax qualified" trust's funds in the securities or assets of any operator of a nuclear power plant.
            (vi) The "non-tax qualified" trust shall be
        
subject to the prohibitions against self-dealing applicable to the "tax qualified" trust as specified in Section 468A of the Internal Revenue Code of 1986, or any successor thereto.
            (vii) All income earned by the trust's funds
        
shall become a part of the trust's funds and subject to the provisions of this Section.
            (viii) The Commission may adopt by rule or
        
regulation such further restrictions as it deems necessary for the sound management of the trust's funds, consistent with the purposes of this Section.
    (d) By 90 days after the effective date of this amendatory Act of 1988, the Commission shall determine an appropriate method to segregate, either internally or externally, all decommissioning funds collected prior to the effective date of this amendatory Act of 1988 by the utility from its customers, and shall order any change in past decommissioning funding methods that the Commission finds necessary. In making its determination of the appropriate funding method, the Commission shall give consideration to, but not be limited by, all applicable federal regulations. The change in funding method shall be phased-in over an appropriate period of time.
    (e) The trustee of a trust shall report annually to the Commission, or more frequently if ordered by the Commission. The report shall include:
        (1) the trust's State and federal tax returns;
        (2) a report on the trust's portfolio of investments
    
and the return thereon;
        (3) the date and amount of payments received by the
    
trust from the public utility;
        (4) a copy of all correspondence between the trust
    
and the Internal Revenue Service; and
        (5) any other information the Commission orders the
    
trust to provide.
    (f) A nuclear decommissioning trust established pursuant to this Section shall be exempt from taxation in Illinois.
    (g) Beginning on or before May 1, 2020, and every 2 years thereafter, the owner or operator of each nuclear power plant in this State shall provide the Commission with a copy of the nuclear decommissioning funding assurance status report submitted to the Nuclear Regulatory Commission and, as applicable, to the Federal Energy Regulatory Commission. Beginning June 1, 2020, and every 2 years thereafter, the Commission shall provide the General Assembly with a copy of the nuclear decommissioning funding assurance status report for shutdown units as submitted by the owner or operator of a nuclear power plant in this State to the Nuclear Regulatory Commission and, as applicable, to the Federal Energy Regulatory Commission.

220 ILCS 5/8-512

    (220 ILCS 5/8-512)
    Sec. 8-512. Renewable energy access plan.
    (a) It is the policy of this State to promote cost-effective transmission system development that ensures reliability of the electric transmission system, lowers carbon emissions, minimizes long-term costs for consumers, and supports the electric policy goals of this State. The General Assembly finds that:
        (1) Transmission planning, primarily for
    
reliability purposes, but also for economic and public policy reasons is conducted by regional transmission organizations in which transmission-owning Illinois utilities and other stakeholders are members.
        (2) Order No. 1000 of the Federal Energy Regulatory
    
Commission requires regional transmission organizations to plan for transmission system needs in light of State public policies and to accept input from states during the transmission system planning processes.
        (3) The State of Illinois does not currently have a
    
comprehensive power and environmental policy planning process to identify transmission infrastructure needs that can serve as a vital input into the regional and interregional transmission organization planning processes conducted under Order No. 1000 and other laws and regulations.
        (4) This State is an electricity generation and
    
power transmission hub, and can leverage that position to invest in infrastructure that enables new and existing Illinois generators to meet the public policy goals of the State of Illinois and of interconnected states while cost-effectively supporting tens of thousands of jobs in the renewable energy sector in this State.
        (5) The nation has a need to readily access this
    
State's low-cost, clean electric power, and this State also desires access to clean energy resources in other states to develop and support its low-carbon economy and keep electricity prices low in Illinois and interconnected States.
        (6) Existing transmission infrastructure may
    
constrain the State's achievement of 100% renewable energy by 2050, the accelerated adoption of electric vehicles in a just and equitable way, and electrification of additional sectors of the Illinois economy.
        (7) Transmission system congestion within this
    
State and the regional transmission organizations serving this State limits the ability of this State's existing and new electric generation facilities that do not emit carbon dioxide, including renewable energy resources and zero emission facilities, to serve the public policy goals of this State and other states, which constrains investment in this State.
        (8) Investment in infrastructure to support
    
existing and new electric generation facilities that do not emit carbon dioxide, including renewable energy resources and zero emission facilities, stimulates significant economic development and job growth in this State, as well as creates environmental and public health benefits in this State.
        (9) Creating a forward-looking plan for this
    
State's electric transmission infrastructure, as opposed to relying on case-by-case development and repeated marginal upgrades, will achieve a lower-cost system for Illinois' electricity customers. A forward-looking plan can also help integrate and achieve a comprehensive set of objectives and multiple state, regional, and national policy goals.
        (10) Alternatives to overhead electric transmission
    
lines can achieve cost-effective resolution of system impacts and warrant investigation of the circumstances under which those alternatives should be considered and approved. The alternatives are likely to be beneficial as investment in electric transmission infrastructure moves forward.
        (11) Because transmission planning is conducted
    
primarily by the regional transmission organizations, the Commission should be advocating for the State's interests at the regional transmission organizations to ensure that such planning facilitates the State's policies and goals, including overall consumer savings, power system reliability, economic development, environmental improvement, and carbon reduction.
    (b) Consistent with the findings identified in subsection (a), the Commission shall open an investigation to develop and adopt a renewable energy access plan no later than December 31, 2022. To assist and support the Commission in the development of the plan, the Commission shall retain the services of technical and policy experts with relevant fields of expertise, solicit technical and policy analysis from the public, and provide for a 120-day open public comment period after publication of a draft report, which shall be published no later than 90 days after the comment period ends. The plan shall, at a minimum, do the following:
        (1) designate renewable energy access plan zones
    
throughout this State in areas in which renewable energy resources and suitable land areas are sufficient for developing generating capacity from renewable energy technologies;
        (2) develop a plan to achieve transmission capacity
    
necessary to deliver the electric output from renewable energy technologies in the renewable energy access plan zones to customers in Illinois and other states in a manner that is most beneficial and cost-effective to customers;
        (3) use this State's position as an electricity
    
generation and power transmission hub to create new investment in this State's renewable energy resources;
        (4) consider programs, policies, and electric
    
transmission projects that can be adopted within this State that promote the cost-effective delivery of power from renewable energy resources interconnected to the bulk electric system to meet the renewable portfolio standard targets under subsection (c) of Section 1-75 of the Illinois Power Agency Act;
        (5) consider proposals to improve regional
    
transmission organizations' regional and interregional system planning processes, especially proposals that reduce costs and emissions, create jobs, and increase State and regional power system reliability to prevent high-cost outages that can endanger lives, and analyze of how those proposals would improve reliability and cost-effective delivery of electricity in Illinois and the region;
        (6) make findings and policy recommendations based
    
on technical and policy analysis regarding locations of renewable energy access plan zones and the transmission system developments needed to cost-effectively achieve the public policy goals identified herein;
        (6.5) make findings and policy recommendations based
    
on analysis regarding the impact of converting non-powered dams to hydropower dams relative to the alternative renewable energy resources; and
        (7) present the Commission's conclusions and
    
proposed recommendations based on its analysis and use the findings and policy recommendations to determine actions that the Commission should take.
    (c) No later than December 31, 2025, and every other year thereafter, the Commission shall open an investigation to develop and adopt an updated renewable energy access plan that, at a minimum, evaluates the implementation and effectiveness of the renewable energy access plan, recommends improvements to the renewable energy access plan, and provides changes to transmission capacity necessary to deliver electric output from the renewable energy access plan zones.

    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 any 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.

    (220 ILCS 5/9-107)
    Sec. 9-107. Revenue balancing adjustments.
    (a) In this Section:
    "Reconciliation period" means a period beginning with the January monthly billing period and extending through the December monthly billing period.
    "Rate case reconciliation revenue requirement" means the final distribution revenue requirement or requirements approved by the Commission in the utility's rate case or formula rate proceeding to set the rates initially applicable in the relevant reconciliation period after the conclusion of the period. In the event the Commission has approved more than one revenue requirement for the reconciliation period, the amount of rate case revenue under each approved revenue requirement shall be prorated based upon the number of days under which each revenue requirement was in effect.
    (b) If an electric utility has a performance-based formula rate in effect under Section 16-108.5, then the utility shall be permitted to revise the formula rate and schedules to reduce the 50 basis point values to zero that would otherwise apply under paragraph (5) of subsection (c) of Section 16-108.5. Such revision and reduction shall apply beginning with the reconciliation conducted for the 2017 calendar year.
    If the utility no longer has a performance-based formula in effect under Section 16-108.5, then the utility shall be permitted to implement the revenue balancing adjustment tariff described in subsection (c) of this Section.
    (c) An electric utility that is authorized under subsection (b) of this Section to implement a revenue balancing adjustment tariff may file the tariff for the purpose of preventing undercollections or overcollections of distribution revenues as compared to the revenue requirement or requirements approved by the Commission on which the rates giving rise to those revenues were based. The tariff shall calculate an annual adjustment that reflects any difference between the actual delivery service revenue billed for services provided during the relevant reconciliation period and the rate case reconciliation revenue requirement for the relevant reconciliation period and shall set forth the reconciliation categories or classes, or a combination of both, in a manner determined at the utility's discretion.
    (d) A utility that elects to file the tariff authorized by this Section shall file the tariff outside the context of a general rate case or formula rate proceeding, and the Commission shall, after notice and hearing, approve the tariff or approve with modification no later than 120 days after the utility files the tariff, and the tariff shall remain in effect at the discretion of the utility. The tariff shall also require that the electric utility submit an annual revenue balancing reconciliation report to the Commission reflecting the difference between the actual delivery service revenue and rate case revenue for the applicable reconciliation and identifying the charges or credits to be applied thereafter. The annual revenue balancing reconciliation report shall be filed with the Commission no later than March 20 of the year following a reconciliation period. The Commission may initiate a review of the revenue balancing reconciliation report each year to determine if any subsequent adjustment is necessary to align actual delivery service revenue and rate case revenue. In the event the Commission elects to initiate such review, the Commission shall, after notice and hearing, enter an order approving, or approving as modified, such revenue balancing reconciliation report no later than 120 days after the utility files its report with the Commission. If the Commission does not initiate such review, the revenue balancing reconciliation report and the identified charges or credits shall be deemed accepted and approved 120 days after the utility files the report and shall not be subject to review in any other proceeding.

220 ILCS 5/9-201

    (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.
    For water or sewer utilities with greater than 15,000 total customers, the following notice requirements are applicable, in addition to the other notice requirements of this Act:
        (1) As a separate bill insert, an initial notice in
    
the first bill sent to all customers potentially affected by the proposed change after the filing of the proposed change shall include:
            (A) the approximate date when the change or
        
changes shall go into effect assuming the Commission utilizes the 11-month process as described in this Section;
            (B) a statement indicating that the estimated
        
bill impact may vary based on multiple factors, including, but not limited to, meter size, usage volume, and the fire protection district;
            (C) the water or sewer utility's customer service
        
number or other number as may be appropriate where an authorized agent of the water or sewer utility can explain how the proposed increase might impact an individual customer's bill;
            (D) if the proposed change involves a change from
        
a flat to a volumetric rate, an explanation of volumetric rate;
            (E) a reference to the water or sewer utility's
        
website where customers can find tips on water conservation; and
            (F) for customers receiving both water and sewer
        
service from a utility and if the customer has an option to install a separate meter for irrigation to mitigate sewer charges, an explanation of the water and sewer utility's and the customer's responsibilities for installation of a separate meter if such a change is approved.
        (2) A second notice to all customers shall be
    
included on the first bill after the Commission suspends the tariffs initiating the rate case.
        (3) Final notice of such change shall be sent to all
    
customers potentially affected by the proposed change by including information required under this paragraph (3) with the first bill after the effective date of the rates approved by the Final Order of the Commission in a rate case. The notice shall include the following:
            (A) the date when the change or changes went into
        
effect;
            (B) the water or sewer utility's customer service
        
number or other number as may be appropriate where an authorized agent of the water or sewer utility can explain how the proposed increase might impact an individual customer's bill;
            (C) an explanation that usage shall now be
        
charged at a volumetric rate rather than a flat rate, if applicable;
            (D) a reference to the water or sewer utility's
        
website where the customer can find tips on water conservation; and
            (E) for customers receiving both water and sewer
        
service from a utility and if the customer has an option to install a separate meter for irrigation to mitigate sewer charges, an explanation of the water and sewer utility's and the customer's responsibilities for installation of a separate meter if such a change is approved.
    (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 administrative law judge 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 administrative law judge 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 administrative law judge 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 administrative law judge who is involved in any such communication shall be recused from the affected proceeding. The Commission, or any commissioner or administrative law judge 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.
