By aggregating many home batteries, Lunar's VPP software dispatches stored energy and flexible loads to support the grid during peak demand. In early 2026 the company said it had raised about $232 million across Series C and Series D rounds, with the $102 million Series D led by B Capital and Prelude Ventures and total funding surpassing $500 million. Lunar operates independently with offices in California and the UK.
