Renewable Resources

The Illinois Renewable Portfolio Standard (RPS) was first established in 2007 and has been substantially updated through Public Act 99-0906 (the "Future Energy Jobs Act"), Public Act 102-0662 (the "Climate and Equitable Jobs Act"), and Public Act 104-458 (the "Clean and Reliable Grid Affordability Act").

The Agency's activities related to the development of new renewable resources to support the Illinois Renewable Portfolio Standard are guided by the Long-Term Renewable Resources Procurement Plan (Long-Term Plan). For more information, visit the Long-Term Renewable Resources Procurement Plan page.

The Long-Term Plan describes the implementation of:

Illinois Shines (also known as the Adjustable Block Program) for photovoltaic distributed generation and community solar.

Illinois Solar for All for low-income photovoltaic distributed generation and community solar.

Utility-Scale Renewable Energy Projects for the procurement of Indexed Renewable Energy Credits from new utility-scale wind projects (projects over 5 MW), new utility-scale solar projects (projects over 5 MW), new brownfield site photovoltaic projects, and new hydropower projects at an existing dam or modernized or retooled hydropower projects at an existing dam.

Energy Storage concerning a key element of the Clean and Reliable Grid Affordability Act (CRGA), which directs the IPA to conduct competitive procurements to support the development of new utility-scale energy storage projects across the state.

Large Customer Self-direct Program for large electric customers to retire Renewable Energy Credits from new utility-scale wind and solar facilities and receive a bill credit reducing Renewable Portfolio Standard (RPS)-related bill charges.

Minimum Equity Standard (MES) for projects receiving Renewable Energy Credit contracts under Illinois Shines or through the IPA’s utility-scale REC procurements for a given Program/delivery year. A MES is the minimum percentage of project workforce for participating projects that must consist of Equity Eligible Persons.

May Workshops

The Agency held workshops in May, 2017 to discuss the implementation of Public Act 99-0906. After the workshops the Agency issued Requests for Comments. Information on the workshops and the responses to the Requests for Comments are contained here:

Initial Forward Procurement

Pursuant to Section 1-75(c)(1)(G) of the Illinois Power Agency Act, the Agency conducted an Initial Forward Procurement for one million annual RECs from new utility-scale wind projects and for 200,000 annual RECs from new utility-scale photovoltaic projects and brownfield site photovoltaic projects in August 2017. The Agency then conducted two additional photovoltaic Initial Forward Procurements each for 400,000 annual RECs in March and April 2018.

Distributed Generation

In 2017 the Agency conducted procurements for distributed renewable generation resources on behalf of Ameren Illinois, ComEd, and MidAmerican pursuant to the Agency's 2017 Procurement Plan.

Public Act 99-0906 also revised how Alternative Retail Electric Suppliers ("ARES") comply with the RPS. ARES compliance with the RPS is determined by the Illinois Commerce Commission.

ARES are recommended to review the changes to the administrative rules related to their RPS compliance (Title 83, Part 455: Renewable Portfolio Standard and Clean Coal Standard for Alternative Retail Electric Suppliers and Utilities Operating Outside their Service Areas).

Emergency Rules were adopted on June 1, 2017, and proposed permanent rules were developed in ICC Docket No. 17-0267.

The Illinois Power Agency procures renewable resources for Ameren Illinois, ComEd, and MidAmerican to meet their Renewable Portfolio Standard obligations.

The Illinois Power Agency also administers the Renewable Energy Resources Fund which is comprised of Alternative Compliance Payments made by Alternative Retail Electric Suppliers as part of their Renewable Portfolio Standard obligations. (Effective June 1, 2017, those payments are no longer made to the Renewable Energy Resources Fund.)

The fund is currently being used to support the $30 million Supplemental Photovoltaic Procurement Plan authorized by the Illinois General Assembly in Public Act 98-0672. View the Plan and procurement results. The Plan included three rounds of procurements in 2015/2016 that have now concluded.

As part of the Long-term Renewable Resources Procurement Plan, the Renewable Energy Resources Fund will also be used to support the Illinois Solar for All Program which will provide additional incentives for low-income households and communities. See the draft Long-Term Renewable Resources Procurement Plan for more information.
