Illinois Shines

Illinois Shines is a state-administered incentive program supporting the development of new solar energy generation in Illinois.

Illinois Shines is the brand name for the Adjustable Block Program, a program developed and managed by the Illinois Power Agency that supports the development of solar in Illinois.

On September 15, 2021 Governor Pritzker signed the Climate and Equitable Jobs Act (Public Act 102-0662). This Act included significant changes to the Adjustable Block/Illinois Shines program. The IPA and the Program Administrator are providing updates on these programmatic changes and the process of reopening the program as they develop.
