Illinois secures battery storage in first auction despite falling short of goal
Summary and headline written by AI from the source article. How we work
In Illinois, a recent auction secured 600 megawatts of battery storage, moving the state closer to a more reliable and clean power system.
The Illinois Power Agency designed the auction to obtain 1,038 megawatts through the Clean and Reliable Grid Affordability Act, aiming to increase utility-scale storage to serve around half a million homes by 2030.
While the auction did not fully meet its target, experts consider the results a positive step, noting that Illinois currently has 141 megawatts of utility-scale battery storage. Central and southern Illinois, operating within the Midcontinent Independent System Operator region, exceeded expectations by securing 520 megawatts from four projects. However, northern Illinois, part of the PJM Interconnection territory, only obtained 80 megawatts from a single project.
James Gignac of the Union of Concerned Scientists suggested delays in connecting new projects to the PJM grid contributed to the shortfall. Supporters anticipate future auctions, planned for 2027 and 2028, will offer more flexibility and potentially allow for projects combining battery storage with solar or wind power. The state still needs to add at least 3,000 megawatts of storage by 2030, and this auction represents the initial phase of that expansion.
The new law also encourages homeowners to participate through virtual power plant programs, combining rooftop solar with home batteries to reduce costs and support the grid.
