About the Program

Illinois Shines is the brand name for the Adjustable Block Program—a state-administered incentive program supporting the development of new solar energy generation in Illinois.

You may participate in Illinois Shines in one of two ways:

  • You may host a new solar photovoltaic system on your rooftop or on your property, directly offsetting your energy usage; or
  • You may participate as a subscriber to a community solar project—a large, centralized solar project for which you “subscribe” to a share of its output.

For your new solar photovoltaic (“PV”) system to participate in Illinois Shines/Illinois Adjustable Block Program, you must work with an Approved Vendor who will apply to the Illinois Power Agency for that PV system to be part of the program. The program provides payments in exchange for 15 years of Renewable Energy Credits (“RECs”) from a utility contracted to buy the RECs from your Approved Vendor. These payments to your Approved Vendor will help offset the cost of your new PV system or your community solar subscription

An explanation of the rationale behind the Illinois Shines branding can be found here.
