About the Program
The Adjustable Block Program was established by the Future Energy Jobs Act (Public Act 99-0906, effective June 1, 2017) to support the development of new photovoltaic distributed generation (e.g., rooftop solar) and community solar projects in Illinois.
The program is run by the Illinois Power Agency through its Program Administrator, InClime.
The Adjustable Block Program will offer a set price for purchase of Renewable Energy Credits (“RECs”) via 15-year contracts from qualifying projects, and the price will be adjusted for successive volumetric blocks (hence the “adjustable block” name) based on market response. The Illinois Power Agency’s goal is to design a series of adjustable blocks with prices that will elicit the maximum amount of deployment at the least possible cost, with a high level of certainty and transparency for market participants. The initial goal for the Adjustable Block Program is to have enough RECs under contract to result in 1,000,000 RECs being delivered annually by the end of the 2020‐2021 delivery year (i.e., May 31, 2021), entailing approximately 666 megawatts of new photovoltaic generation in the state.
More information on the Adjustable Block Program can be found in the Illinois Power Agency’s Long-Term Renewable Resources Procurement Plan. The chapters of the plan outlining the Adjustable Block Program are Chapter 6 and 7.
