Google announced a new agreement with Voltus to fund a 1 GW virtual power plant (VPP) in the PJM grid, the largest grid region in the U.S., utilizing distributed energy devices at homes and businesses to support grid reliability and meet growing data center power demand.

The announcement marks a major expansion of the companies’ current collaboration, with a 100 MW deal announced in June 2026, with the new agreement now representing one of the largest known distributed capacity portfolios deployed by a hyperscaler to date.

Voltus CEO Dana Guernsey said:

“This significant expansion of our work with Google translates data center growth into direct economic benefits for businesses and homes. Through this partnership we are proud to bring much needed clean capacity online, at gigawatt scale.”

Founded in 2016, San Francisco-based Voltus operates and virtual power plant platform that connects distributed energy resources to electricity markets, delivering less expensive, more reliable, and more sustainable electricity. The company’s “Bring Your Own Capacity” solution taps the latent capacity in batteries, cooling systems, and industrial processes across thousands of businesses and homes and dispatches it into electricity markets, enabling the grid to draw more out of existing infrastructure, while allowing participants to reduce, shift, or supply power to lower energy costs and earn revenue.

Earlier this month, Voltus announced that it has raised $225 million in a financing round, with the company planning to use the new capital to expand its platform to 20 GW by 2030.

Under the agreement, Voltus will aggregate flexible capacity from devices such as batteries and smart thermostats at local homes and businesses into a Google-funded virtual power plant, with the assets temporarily reducing energy use to support grid reliability, while participating customers will receive direct economic benefits, including bill savings and cash payments.

Ellen Zuckerman, Head of Energy Market Development for North & South America at Google, said:

“Distributed energy resources are powerful tools for managing a modern, reliable grid while keeping energy affordable. Expanding our initial commitment tenfold demonstrates our core effort to actively bring our own capacity to the grids that serve us.”
