Illinois has taken a major step toward reshaping how the state plans for reliable electricity and more stable energy costs. On January 8, 2026, Governor J. B. Pritzker signed the Clean and Reliable Grid Affordability Act, a wide-ranging energy package designed to expand energy storage, strengthen efficiency, and create new tools for long-term resource planning.
In Illinois, the business case for solar-plus-storage is strengthening. Emerging grid programs and procurement pathways are set to maximize the return on investment for battery-integrated systems over the coming years.
What Changed Under the Clean and Reliable Grid Affordability Act?
The new law includes several provisions that are directly relevant to commercial solar and battery storage projects, offering potential incentives for businesses investing in solar. The main provisions include:
1. A Virtual Power Plant Program That Can Pay Customers for Grid Support
The Act requires utilities to create virtual power plant programs that compensate participating households and businesses for using customer-sited energy resources, such as solar, small batteries, smart thermostats, and electric vehicle charging, in ways that support the grid during periods of high demand.
For businesses considering solar and battery storage, this is a meaningful shift. Instead of batteries only providing backup power and demand savings, Illinois is also building a pathway for batteries to provide grid services and earn revenue through structured programs.
2. A Statewide Push to Add Three Gigawatts of Battery Storage by 2030
Illinois is establishing a statewide procurement target that aims to bring three gigawatts of grid-scale battery storage online by December 31, 2030.
While this target focuses on the grid, the ripple effects matter for businesses, including increased market momentum for storage, clearer policy direction, and more attention to storage as a tool for reliability and cost control. The ultimate impact will be a more reliable grid with fewer costly power outage events.
3. Faster, More Predictable Siting and Permitting for Storage Projects
The Act extends clean energy siting reforms to energy storage and expands state involvement in resolving siting disputes.
It also places structure around local permit fees. For example, energy storage project siting and building permit fees now have additional conditions tied to documented processing costs.
For project owners, streamlined permitting and clearer fee expectations can lower soft costs, reduce uncertainty, and shorten the time between design and operation. Ultimately, a more organized permitting process will likely result in quicker approval times.
4. More Energy Efficiency Incentives and a Stronger Planning Cycle
The Act expands energy efficiency programming and creates an integrated resource planning process to forecast electricity needs and evaluate cost-effective options.
Energy efficiency stakeholders can expect a more predictable schedule, featuring multi-year filings and a longer-range planning cycle. For businesses, these improvements translate to lowering long-term costs and more opportunities to claim incentives for efficiency upgrades that reduce overhead.
5. New Support for Geothermal Heating and Cooling
The Act also rewards businesses that use geothermal heating and cooling. Starting in June 2028, these systems will be eligible for renewable energy credits, providing a new way to offset costs through long-term state planning.
While solar and battery storage often lead the conversation, geothermal may become a complementary option for facilities that desire low-carbon heating and cooling with long-term operating stability.
When Will the CRGA Take Effect?
Though the CRGA was signed in January 2026, not every program will fully operate immediately:
- The law takes effect June 1, 2026.
- The Illinois Power Agency is expected to develop a storage procurement plan for stakeholder review in 2027, with an initial procurement timing referenced around August 26, 2026, subject to updates.
- Several major planning milestones land in 2026 and beyond, including integrated resource planning timelines and the shift into future multi-year cycles.
It’s reasonable to view 2026 as a “setup year,” with more visible customer-facing program impacts emerging later in 2027 or even 2028 as implementation progresses.
What Can Businesses Do Now to Prepare for the CRGA?
Even if some programs take time to mature, businesses can position themselves favorably now. Planning ahead ensures that your facility is well-poised to reap the maximum benefits of the CRGA once all provisions are fully operational.
Evaluate Your Solar and Battery Storage as a Combined Strategy
Battery storage can support operational continuity during outages, reduce peak demand exposure, and potentially participate in grid programs as they come online. Illinois is explicitly moving toward more storage on the system, and customer participation mechanisms are part of that direction.
Start Early On-Site Solar Planning and Interconnection Conversations
If your facility is a candidate, starting your design and feasibility work now will put you at the front of the line once incentives and program details are officially released. Evaluating on-site solar systems now will put you in the best spot to take advantage of incentives as they become available.
Coordinate State Benefits with Federal Incentives Carefully
Some projects may still qualify for meaningful federal tax incentives depending on eligibility and timing, but federal policy and phaseout schedules can change. Tick Tock Energy recommends aligning your energy project plan with your tax and finance advisors early, so you can evaluate the best available path based on your business structure and risk tolerance.
