Illinois Becomes Hotbed for Virtual Power Plants as New Law Takes Effect
Solrite Energy is launching a virtual power plant program in Illinois, offering households battery storage for $20 per month and using those batteries to support the grid. The move comes after Illinois passed a law mandating utilities to develop such programs. Illinois is now among several states where virtual power plants are rapidly expanding.
Solrite's business model centers on leasing oversized battery systems to homeowners rather than selling equipment outright. The company, which rebranded from Solnova in 2023, operates roughly 7,500 residential systems across five states and employs about 50 people. Its 60-kilowatt-hour batteries far exceed typical household needs—ComEd customers average around 20 kilowatt-hours daily—leaving ample capacity for grid services while still providing multi-day backup during outages.
Illinois's Clean and Reliable Grid Affordability Act, signed in January, mandates utility-developed virtual power plant programs, prompting rapid market entry from multiple firms. Solrite joins Base Power and Energywell in serving ComEd and Ameren territories. VPPs encompass diverse technologies beyond batteries, including smart thermostats and water heaters, reflecting a broader national trend as states seek flexible grid resources amid rising electricity demand.
This expansion could reshape household energy economics, making battery backup accessible to lower-income residents who cannot afford upfront equipment costs. Widespread VPP adoption may improve grid reliability during peak demand and reduce the need for fossil-fuel peaker plants. However, success depends on customer retention and whether utilities adequately compensate participants. If these programs scale effectively, they could accelerate the clean energy transition while giving ordinary households a direct stake in grid operations—though long-term consumer protections and pricing transparency will determine whether benefits are equitably distributed.
