CHICAGO, IL – On Tuesday, the Illinois Commission (ICC) approved the Illinois Power Agency’s (IPA) 2026 Long-Term Renewable Resources Procurement Plan (LTRRPP) which guides procurement of new renewable generation in Illinois over the next two years. The IPA’s plan encourages investment in both utility scale and community solar, utility-scale wind, hydropower, and other clean energy projects in Illinois.
“Getting affordable energy capacity projects built in Illinois will be an essential part of protecting ratepayers from our country’s growing energy demands for years to come. The latest renewable procurement incentives approved by the ICC aim to help rectify our state’s expanding energy needs while still protecting consumers’ pocketbooks,” said ICC Chairman Doug Scott. “The updated plan includes program improvements, procurement targets, and budgets designed to keep Illinois on track to affordably and fairly meeting its decarbonization goals.”
The 2026 LTRRPP includes the IPA’s proposed procurement of Renewable Energy Credits (RECs) for Ameren Illinois, Commonwealth Edison Company, and MidAmerican Energy Company for program years 2026-2027 and 2027-2028 and includes proactive, stakeholder-supported measures to help address projected near-term funding challenges and federal uncertainty.
The IPA’s first plan was approved in 2018. Since then, Illinois has become a national leader in driving the transition to clean energy.
- Illinois has installed over 14GW of renewable energy generating capacity as of 2025. The installed capacity value is a combined result of IPA-facilitated procurements and programs (indexed REC procurements, Illinois Shines, Illinois Solar for All, etc.) and independently developed projects.
- Illinois leads the Midwest in installed solar capacity, ranking 4th nationally for most solar installations nationally, according to the Solar Energy Industries Association.
- The Institute for Local Self-Reliance’s Community Power Scorecard awarded Illinois its highest grade, above all other states, for state policies to expand energy democracy in both 2024 and 2025.
- Since April 2025, 20 percent of all electricity production in Illinois constituted renewable energy, eclipsing both coal and natural gas, according to the U.S. Energy Information Association.
The ICC is required by law to review the LTRRPP every two years. In accordance with updates made to Illinois law under the Clean and Reliable Grid Affordability Act, the IPA is required to file an updated 2026 plan on June 1, 2026.
