Notes from Illinois’ Virtual Power Plant Frontier

Illinois is emerging as a key player in the rapidly evolving landscape of virtual power plants (VPPs), with Solrite Energy launching a new initiative that offers residents affordable battery storage solutions while contributing to grid stability. The program, announced today, allows households to lease battery systems for $20 per month, providing both energy independence and support to the regional power grid during peak demand periods. Solrite Energy, based in Fort Worth, Texas, has expanded its operations to Illinois, joining established players such as Base Power and Energywell in offering solar and battery services to customers served by ComEd and Ameren, the state's two major electricity providers. This expansion follows the passage of the Clean and Reliable Grid Affordability Act in January, which mandated utilities to develop VPP programs as part of broader efforts to modernize the state’s energy infrastructure. A virtual power plant functions as a decentralized network of distributed energy resources, such as batteries, solar panels, and even grid-connected appliances, that can collectively provide grid support by either supplying electricity or reducing demand. Unlike traditional power generation, VPPs leverage existing infrastructure to enhance efficiency and reliability. In Illinois, Solrite’s approach involves installing large-capacity batteries in residential properties, enabling these homes to act as mini-power stations when needed. Regan George, Solrite’s founder and CEO, explained that the company strategically selects locations where it has agreements with utilities or grid operators. These partnerships allow Solrite to access the stored energy from its leased batteries during times of high grid stress, ensuring that the utility can maintain stable service while compensating Solrite for its contribution. The company began as Solnova in 2017, focusing primarily on rooftop solar installations, before rebranding as Solrite in 2023 to emphasize its shift toward VPP technologies. Under Solrite’s current model, customers can opt for a monthly payment plan that includes the installation of a 60-kilowatt-hour battery, significantly larger than the typical residential requirement. This capacity ensures that households can remain powered during outages, with sufficient storage to sustain daily usage for several days. The company also offers optional solar panel installations, allowing customers to generate their own electricity at a discounted rate of 12 cents per kilowatt-hour, which is lower than the standard utility rate. The cost of purchasing a similar battery and solar setup outright would exceed $30,000, making Solrite’s leasing option a more accessible alternative. By owning the equipment and managing its deployment, Solrite ensures that the batteries are optimized for grid support, drawing from multiple units simultaneously to create a scalable power resource akin to a conventional power plant. Solrite utilizes batteries specifically designed for VPP applications, rather than repurposing consumer-grade models. Manufacturers such as Duracell and Sonnen supply these specialized units, which are engineered to operate efficiently within the framework of a coordinated energy network. This distinction enhances performance and reliability, aligning with the growing demand for resilient, sustainable energy solutions. As Solrite continues to expand its footprint in Illinois, the company plans to increase its workforce and operational reach, currently serving approximately 7,500 homes with its VPP systems. With around 50 employees, Solrite is positioning itself as a leader in the state’s clean energy transition, leveraging innovative technology and strategic partnerships to drive progress in the sector.
