Discover how Illinos has pioneered, laying the groundwork for solar energy initiatives nationwide. This page will guide you through the state’s evolving solar policies and the advantages of community solar programs. Join us as we work to enhance access to sustainable energy for everyone!
Illinois’s solar policy has evolved significantly over the years. We’ve seen various legislative efforts aimed at promoting renewable energy and community solar initiatives. This timeline provides an overview of the critical milestones that have shaped our state’s approach to solar energy, helping residents access more sustainable energy solutions.
In 2016, the Illinois General Assembly passed the landmark Future Energy Jobs Act (FEJA). This legislation laid the groundwork for the state's first community solar program and created the Adjustable Block Program, now known as Illinois Shines. FEJA also introduced ambitious clean energy targets and incentivized developers to create solar farms that residents could subscribe to without rooftop installation.
During 2017 and 2018, the Illinois Power Agency (IPA) developed the technical and regulatory framework to operationalize FEJA. This included designing the Renewable Energy Credit (REC) incentive structure and establishing the initial block capacity model. Developers began submitting project bids to participate in the emerging solar market.
In April 2019, Illinois held its first community solar lottery. Demand for project approvals significantly outpaced the available capacity, leading to a randomized selection process in which 112 projects were chosen to move forward. This marked the official launch of community solar construction in the state.
Between 2019 and 2021, many of those selected projects began construction and came online. As the solar farms became operational, households across the state began subscribing and receiving solar bill credits, saving an average of 10–20% on their utility bills. Participation quickly grew, thanks in part to the model requiring no rooftop panels or equipment.
In 2021, Illinois passed the Climate and Equitable Jobs Act (CEJA). This transformative law expanded the state’s renewable energy goals to 40% by 2030 and 50% by 2040. CEJA cleared a substantial backlog of ~250 MW in pending community solar projects and dramatically increased funding for Illinois Solar for All — multiplying its budget fivefold to enhance energy equity for low- to moderate-income families.
From 2022 to 2024, Illinois entered a rapid expansion phase. The state added more than 170 MW of new community solar capacity and opened annual capacity blocks ranging from 150–250 MW. Today, more than 35,000 subscribers benefit from local solar generation, and new innovations — including unified billing — are making it even easier for income-qualified households to participate.
Illinois was one of the earliest adopters of a structured, equitable community solar model — prioritizing access, transparency, and measurable savings. With ongoing capacity growth and strong oversight from the IPA and state legislation, Illinois continues to lead by example.
Whether you’re a homeowner, a renter, or a local business, there’s a place for you in Illinois community solar.
