Does Illinois Have Community Solar Laws?

Yes. Illinois has some of the most robust and successful community solar laws in the United States. The legal foundation for community solar projects in the state is found in the Future Energy Jobs Act (FEJA) of 2016 and the Climate and Equitable Jobs Act (CEJA) of 2021. Together, these landmark laws established strong policy frameworks that promote renewable energy access, support local solar development, and ensure equitable participation across income levels.

The Illinois Power Agency (IPA) oversees the state’s Adjustable Block Program (ABP), also known as Illinois Shines, which provides financial incentives for the development of community solar energy systems and other distributed generation projects. The ABP compensates project owners through Renewable Energy Credits (RECs), helping reduce the cost of subscription programs for consumers.

Illinois Shines (Adjustable Block Program)

Under the Illinois Shines Program, developers of community solar projects can receive payments for each megawatt-hour (MWh) generated over 15 years. These incentives make projects financially viable while ensuring that subscribers pay affordable rates. The IPA regulates the program to maintain transparency and fairness in pricing and customer enrollment.

Illinois Shines supports community solar farms up to 5 megawatts (MW) in capacity and allows both residential and commercial customers to participate. Subscribers receive bill credits directly from their utility, such as ComEd, Ameren Illinois, or MidAmerican Energy, for their portion of the solar energy produced.

Climate and Equitable Jobs Act (CEJA)

The Climate and Equitable Jobs Act (2021) expanded FEJA’s clean-energy goals and introduced stronger equity provisions. CEJA increased the total renewable-energy targets to 50% by 2040 and specifically allocated funding for community solar projects serving low-income households and environmental-justice communities.

CEJA also established the Illinois Solar for All (ILSFA), which provides free or heavily discounted solar subscriptions for income-eligible residents. The law requires that at least 25% of the state’s new renewable projects directly benefit low-income and disadvantaged populations.

Low-Income Provisions

Illinois is a national leader in designing inclusive community solar energy programs. Through Illinois Solar for All, eligible households can subscribe to community solar farms at no upfront cost and receive guaranteed bill savings of at least 50% of the value of the energy credits they earn. The program’s funding comes from utility surcharges and state clean-energy budgets, ensuring sustainable support.

In addition, CEJA created the Equity Accountability System, requiring project developers to meet workforce diversity and community benefit standards. These measures ensure that Illinois’ transition to renewable energy provides broad social and economic advantages, in addition to the obvious environmental ones.

What Is Community Solar?

Community solar is a shared renewable-energy model that enables multiple customers to benefit from a single solar installation. Instead of installing panels on their property, participants subscribe to a nearby solar facility and receive credits on their utility bills for their share of the energy produced.

This arrangement removes common barriers to residential solar, such as high installation costs, unsuitable roofs, or property ownership limitations. Participants gain access to clean energy without maintenance or equipment burdens.

When Community Solar Is a Good Option

Community solar works particularly well for:

  • Renters and condo residents who can’t install rooftop panels
  • Homeowners with shaded or aging roofs
  • Residents who can’t afford large upfront investments
  • Businesses seeking low-risk participation in renewable energy

By separating energy generation from property ownership, community solar projects make renewable power accessible to everyone, from urban tenants in Chicago to farmers and small businesses in rural Illinois.

Advantages of Community Solar Over Residential Solar

Although residential solar ownership allows direct control over energy systems, community solar farms offer convenience and flexibility unmatched by rooftop systems. Key advantages include:

  • No installation required: Subscribers avoid permits and roof repairs
  • Low or no upfront costs: Most programs require only monthly payments or pre-paid energy credits
  • Shared maintenance: Project operators handle upkeep, performance monitoring, and insurance
  • Scalable access: Participants can adjust subscription size based on their energy needs
  • Inclusive participation: Renters and low-income households can benefit equally

For Illinois residents, these benefits make community solar an appealing entry point into the clean-energy economy.

Why Community Solar?

The benefits of community solar in Illinois go far beyond cost savings. The model supports environmental protection, job creation, and statewide equity in renewable energy adoption.

Energy Accessibility and Equity

Illinois’ clean-energy framework intentionally prioritizes accessibility. Under Illinois Shines and Illinois Solar for All, every customer, regardless of homeownership status, can subscribe to community solar projects. These programs specifically target low-income and historically disadvantaged communities, ensuring renewable-energy participation across demographic and geographic lines.

This focus on inclusion has made Illinois one of the few states where more than 20% of community solar capacity serves low-income subscribers, a benchmark rarely achieved elsewhere in the country.

Consumer Savings

Participants in Illinois community solar programs typically save 10–20% on annual electricity costs compared to standard utility rates. The savings come from bill credits, which offset part or all of the participant’s electricity consumption. For subscribers in the Solar for All program, savings can exceed 50%.

Unlike residential solar, where the owner bears the maintenance and financing burden, community solar subscribers simply pay for the credits generated by their share. The transparent subscription structure ensures predictable energy bills, which is especially beneficial amid rising retail electricity rates.

Environmental and Economic Impact

Each community solar farm contributes to Illinois’ goal of reaching 100% clean energy by 2050. Collectively, community solar installations reduce greenhouse gas emissions by hundreds of thousands of metric tons annually while stimulating local economies through land-lease payments and tax revenue.

Projects also generate jobs in construction, electrical work, and long-term operations. CEJA’s workforce provisions ensure these opportunities reach underrepresented groups, creating a more equitable green-jobs sector across Illinois.

Grid Modernization and Resilience

By decentralizing energy production, community solar strengthens the grid and reduces the need for large-scale transmission infrastructure. Distributed solar generation improves reliability, especially during summer peaks when electricity demand is highest.

Utilities such as ComEd and Ameren Illinois have reported that community solar integration enhances grid stability, reduces congestion, and provides more consistent voltage support, all while increasing renewable generation capacity.

Are There Community Solar Projects in Illinois?

Yes. Illinois has one of the fastest-growing community solar markets in the country. As of 2026, there are over 400 active and planned community solar projects, representing more than 1.2 gigawatts (GW) of installed capacity. These installations serve tens of thousands of residential and commercial subscribers statewide.

The Illinois Power Agency continues to approve new projects annually under the Illinois Shines program, with a focus on expanding rural access and low-income participation.

  • Check availability: Confirm that your address is within the utility’s service area
  • Select a project: Choose a developer or program listed under Illinois Shines
  • Subscribe: Sign a contract defining your share, usually 25 to 100% of average energy use
  • Receive credits: Monthly credits appear on your utility bill, reducing the amount owed

Most subscriptions require no credit check, deposit, or long-term commitment, making the process simple and inclusive. Some developers even offer mobile apps for managing subscriptions and tracking savings.

How Does Community Solar Work in Illinois?

In Illinois, community solar energy operates through the net-crediting system, in which solar electricity produced by a shared facility is sent to the grid. The utility, ComEd, Ameren, or MidAmerican, then applies credits to subscribers’ monthly bills based on their share of the total energy generated.

Credit Structure and Utility Coordination

Under state law, the value of each credit equals the full retail rate of electricity minus certain delivery and service charges. Credits are applied automatically, meaning customers do not have to make separate payments to the utility for their solar energy portion.

Utilities manage the billing process, while developers handle subscription management. The Illinois Power Agency and the Illinois Commerce Commission (ICC) oversee compliance, ensuring transparency in consumer pricing and contract terms.

Incentives and Program Oversight

Developers of community solar projects receive incentives under the Adjustable Block Program for each MWh generated. The state pays these incentives over 15 years in exchange for Renewable Energy Credits that count toward Illinois’ renewable portfolio goals. These incentives reduce project costs, which developers pass on to subscribers through lower rates.

Real-World Example

The Summit Ridge Energy Community Solar Project in Cook County illustrates how community solar farms function in Illinois. Subscribers purchase shares equivalent to part of their typical electricity use. Each month, they receive a credit for the energy their share produced, typically around $5 to $15 per 100 kWh, reducing their total electricity bill.

The project serves over 4,000 subscribers and is part of a larger network of shared solar facilities contributing to the state’s renewable portfolio. Similar models operate in Peoria, Rockford, and Belleville, each providing both economic and environmental benefits to the surrounding communities.

How Much Does Community Solar Cost in Illinois?

The community solar cost in Illinois depends on program structure, subscription size, and utility service territory. Most Illinois programs require no upfront payment. Instead, subscribers pay a discounted rate for solar credits, ensuring immediate bill savings.

There are two common pricing models:

  • Discounted Credit Model: Subscribers pay for energy credits at a fixed discount (typically 10 to 20%) below the utility’s standard rate
  • Fixed-Bill Model: Customers pay a steady monthly rate based on average energy use, providing predictability and insulation from price fluctuations

For example, a ComEd customer who subscribes to 5 kW of community solar capacity might pay $55 to $70 per month, depending on contract terms. Monthly savings typically range from $10 to $25, but can be higher in sunny months with greater production.

Installing residential solar in Illinois costs around $2.70 to $3.10 per watt in 2026, or roughly $18,900 to $21,700 for a standard 7-kW system before incentives. While homeowners who purchase panels outright can realize long-term savings, community solar projects provide instant access to clean energy without loans, maintenance, or property modifications.

For renters and lower-income households, the community solar model represents the most practical and inclusive option available.

Factors Affecting Community Solar Cost

  • Utility Credit Rate: Slight variations between ComEd and Ameren service areas influence total savings
  • Subscription Size: Larger shares generate higher credits but cost more monthly
  • Contract Length: Some developers offer 12-month rolling contracts; others require multi-year commitments
  • Project Incentives: Developers receiving Illinois Shines or Solar for All funding can offer deeper discounts

Because Illinois’ clean-energy laws guarantee long-term funding for community solar projects, prices remain stable and predictable. As more projects come online, competition is expected to lower subscription rates further.

Additionally, participants in Illinois Solar for All face zero subscription fees and receive immediate bill reductions, ensuring that even the state’s most economically vulnerable households can benefit from renewable energy.
