Voltus
Voltus is a Grid Software & VPPs company founded in 2016 and based in San Francisco, USA.
Voltus was founded in 2016 and is based in San Francisco, with a fully remote team. Its distributed energy resource platform enrolls commercial, industrial and residential customers, controls their batteries, smart thermostats, backup generation and process loads through software, and offers the combined flexibility into nine wholesale markets: AESO, CAISO, ERCOT, IESO, ISO-NE, MISO, NYISO, PJM and SPP. Customers earn demand-response and capacity payments through the platform, and under its Bring Your Own Capacity program, launched in PJM in September 2025, data-center developers pay Voltus to add distributed capacity to the grids that serve them. The company reports about 8.5 GW of distributed resources under management and targets 20 GW by 2030. It acquired battery startup Brightfield AI in June 2026. On October 8, 2026, Voltus raised a $225M Series D led by Generation Investment Management, with Activate Capital and Vitol as co-leads; its previous round was a $31M Series C in 2021.
Voltus turns distributed load and batteries into capacity that grid operators can call on when the system is strained. Google signed a 100 MW virtual power plant deal with Voltus in PJM in June 2026 and added 1,070 MW on October 22, 2026, with the capacity contracted through 2040. The deal tests whether data centers can bring their own flexible capacity instead of waiting for new generation. The $225M Series D raised in October 2026 funds a planned scale-up to 20 GW by 2030.
