(This Section may contain text from a Public Act with a delayed effective date ) Sec. 16-201. Integrated resource plan development. (a) The General Assembly hereby finds that: (1) In 2021, Illinois set itself on the path to a clean energy future that would produce the least amount of carbon and copollutant emissions while ensuring adequate, reliable, affordable, efficient, and environmentally sustainable electric service at the lowest total cost over time and in a manner that benefits the Illinois economy and workforce and improves the quality of life, including environmental health, for all its citizens. (2) In the ensuing years, Illinois has created a strong economic environment that has led to the revitalization and expansion of its manufacturing sector and has made Illinois an attractive place for the technology industry to locate new data and quantum computing centers. These developments have led to the creation of good-paying jobs for working families. (3) The unforeseen growth in the manufacturing and technology sectors will likely lead to a dramatic increase in electricity demand over time. (4) The long interconnection times and the capacity market structures enacted by the 2 regional transmission organizations that Illinois is split between further exacerbate the potential for an imbalance between electricity supply and demand. (5) The new sources of load growth from the manufacturing and technology sectors combined with external challenges require a more nimble and responsive administrative approach to effectively address future resource adequacy challenges. (6) The Illinois agencies that oversee and implement Illinois energy policy must have the ability to (i) fully understand current and future resource adequacy needs, (ii) plan for what resources could be utilized to address such needs, (iii) be able to coordinate, modify, expand, and direct all of Illinois' existing energy programs and policies so as to address any resource adequacy or reliability concerns, and (iv) direct the development of new energy programs and policies in order meet resource adequacy and reliability needs without the need for additional legislative action. (b) The purpose of this Section is to ensure that the Commission, the agencies, electric utilities supplying electric service in Illinois, stakeholders, market participants, and policymakers have a common set of data and information regarding the State's electricity resource needs in order to plan for sufficient electricity resources to serve Illinois customers in a manner that is adequate, safe, reliable, affordable, efficient, environmentally sustainable, at the lowest cost over time, and consistent with the energy policy goals of the State, including, but not limited to, the clean energy policy established by Public Act 102-662. To that end, this Section establishes a requirement that the agencies prepare an integrated resource plan and submit such plan to the Commission consistent with this Section for the Commission's review and approval after an opportunity for notice and hearing. (c) Unless otherwise specified, as used in this Section, the following terms shall have the following meanings: (1) "Advanced transmission technologies" means technologies, tools, and software that improve power flows over transmission systems and lines. "Advanced transmission technologies" includes, but is not limited to, the following: (i) technology that dynamically adjusts the rated capacity of transmission lines based on real-time conditions; (ii) advanced power flow controls used to actively control the flow of electricity across transmission lines to optimize usage or relieve congestion; (iii) software or hardware used to identify optimal transmission grid configurations or enable routing power flows around congestion points; and (iv) advanced transmission line conductors that have a direct current electrical resistance at least 10% lower than existing conductors of a similar diameter on the transmission system. (2) "Agencies" means the Illinois Commerce Commission Staff, the Illinois Power Agency, the Illinois Finance Authority, the Illinois Environmental Protection Agency, and any consultants those agencies retain, including, but not limited to, the consultant retained by the Commission pursuant to subsection (j) of this Section and the consultant retained by the Illinois Power Agency pursuant to paragraph (1) of subsection (a) of Section 1-75 of the Illinois Power Agency Act. (3) "Clean energy" means energy generation that either: (A) emits no on-site SO 2 , NO x , mercury, or any other regulated pollutants; or (B) as shown through pollution control technologies, has reduced a generator's CO 2 emissions by 90% compared to what the generator would have otherwise emitted and that has CO 2 emissions less than 130 lb/MWh. (4) "Regional transmission organization" or "RTO" means PJM Interconnection, LLC (PJM) and the Midcontinent Independent System Operator, Inc. (MISO) or the regional transmission organization or independent system operator of which the electric utility is a member or would be a member, given the location of the electric utility's customers, if it were required to be a member. (d) The agencies, coordinated by Commission staff, shall compile and propose an integrated resource plan in compliance with this Section. The agencies may consult with each electric utility that has more than 500,000 electric retail customers in developing the plan and the plan shall consider any necessary interactions between RTO zones in the State. Commission staff shall submit the initial integrated resource plan to the Commission no later than November 15, 2026, the second integrated resource plan to the Commission no later than September 30, 2029, and each subsequent plan to the Commission every 4 years thereafter no later than September 30 of the applicable year. For the first integrated resource plan due on November 15, 2026, the agencies shall take into account the resource adequacy report prepared pursuant to subsection (o) of Section 9.15 of the Environmental Protection Act and shall specifically address any and all divergences from the analysis and conclusions in the report. At any time after the submission of a plan, the agencies may submit an update to the plan if the agencies believe that a material change in the inputs or conclusions of the plan is warranted. The agencies shall notify the Commission as soon as practicable of the material change and the potential update to the plan. The Commission shall publish the integrated resource plan on its website. (e) An alternative retail electric supplier shall provide information related to the resource needs of its customers located in an electric utility's service territory as requested by the agencies or the Commission to compile and develop the plan required by this Section. (f) Commission staff shall lead the agencies in the development of the integrated resource plan to ensure that a plan submitted pursuant to this Section includes a detailed analysis of the following: (1) an evaluation of the future electric resource needs in each electric utility's service area for periods of at least 5, 10, 15, and 20 years such that the plan coincides with the timelines established in Section 9.15 of Title II of the Environmental Protection Act and is designed to support those standards to the maximum extent practicable on the schedule established therein; (2) peak demand and energy usage forecasts, such that the plan: (i) contains no fewer than 3 scenarios of (i) forecasted peak demand, (ii) net peak demand if different from peak demand, (iii) non-coincidental peak demand, and (iv) energy usage, to capture a reasonable range of forecasts based on historic trends and a diverse range of more conservative to high load growth based on reasonable projections.
