Base Power Takes Its Virtual Power Plant to the Strained PJM Grid

The startup, which previously established a virtual power plant in Texas, utilizes large-scale residential battery systems starting at 25 kilowatt-hours. Instead of selling hardware, Base Power functions as a utility provider, charging batteries when market prices are low and dispatching energy during peak demand. This strategy allows the company to bypass the grid operator’s notorious interconnection delays by deploying capacity behind the meter at existing residential connections.

Base Power’s expansion follows a rapid capital injection, including a $1 billion round led by Addition in October and a $200 million investment led by Andreessen Horowitz, Lightspeed Venture Partners, and Valor Equity Partners earlier this year. The company’s arrival comes as PJM faces mounting criticism for its handling of grid capacity, having paused new generation applications for two years before reopening its queue this past April. With over 500 megawatt-hours of storage already operational in Texas, founder and CEO Zach Dell is positioning the firm to capitalize on the acute energy crunch currently threatening major utilities like AEP.
