Google and Voltus have expanded their virtual power plant partnership in the PJM grid region to 1 gigawatt, the companies announced on October 22, 2026.

Agreement Scaled Tenfold Since June

The new agreement adds 1,070 MW of capacity on top of the 100 MW commitment made in June 2026, and according to the companies, it represents one of the largest known distributed capacity portfolios deployed by a hyperscaler to date.

The original deal, signed in June 2026, committed the two companies to deliver 100 megawatts of flexible power capacity in PJM, the grid operator serving 67 million customers across 13 states and the District of Columbia.

Under the expanded arrangement, Voltus will build a 1 GW virtual power plant designed to unlock new capacity and deliver savings for customers.

Inside the Virtual Power Plant Model

The mechanism mirrors the structure of the first agreement. Voltus aggregates new capacity from local businesses and homes into a virtual power plant funded by Google. When the grid comes under strain, Voltus signals participating sites, which respond by drawing on batteries, smart thermostats, industrial process adjustments, and other flexible assets to reduce their energy use.

Voltus then passes financial benefits back to participants in the form of bill savings and direct payments.

According to the companies, this structure converts Google's demand for capacity into real economic benefits for PJM customers. A recent report from The Brattle Group cited in the announcement predicts that U.S. consumers could save more than USD 100 billion over the next decade through better grid utilization.

Google Frames the Deal as Grid Support

"Distributed energy resources are powerful tools for managing a modern, reliable grid while keeping energy affordable," said Ellen Zuckerman, head of energy market development for North & South America at Google. "Expanding our initial commitment tenfold demonstrates our core effort to actively bring our own capacity to the grids that serve us.

Procuring this capacity through a gigawatt-scale virtual power plant ensures Google's operations in PJM support regional reliability and deliver direct economic benefits to local communities." Zuckerman's comments point to the Bring Your Own Capacity model that anchors the partnership.

Voltus's BYOC program brings new flexible capacity to the grid, enabling its commercial and industrial customers and DER partners to earn value as Voltus maximizes the market value of their flexible load, distributed generation, energy storage, energy efficiency and electric vehicle resources.

Voltus CEO Dana Guernsey said the expansion 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," she said. Both companies frame the arrangement as a way to reconcile rising electricity demand from data centers with regional reliability.

Instead of adding demand to PJM without offsetting contributions, Google is funding capacity aggregated from distributed sources across the region.

A Busy Year for Voltus

The expanded Google deal caps a series of announcements from the distributed energy resource platform. The original first-of-its-kind agreement with Google, announced in June 2026, was intended to aggregate up to 100 MW of accredited distributed capacity in PJM and channel grid investment to homes and businesses.

Also in June, Voltus acquired Brightfield AI to accelerate energy storage deployment, picking up a battery development platform and a team of distributed storage veterans. The company expanded its senior leadership that same month, naming industry veterans Arielle Bertman as Vice President of Product and Jess Gunter as Vice President of Marketing.

Activity continued through the summer.

In August 2026, Sunrun agreed to supply Voltus with energy capacity for AI hyperscaler agreements, with Voltus drawing on Sunrun's solar-plus-storage systems to deliver immediate BYOC megawatts to AI hyperscalers across the PJM and MISO regions.

In September 2026, Siemens and Voltus formed a partnership to help commercial building operators generate virtual power plant revenue by integrating Voltus's energy monetization capabilities with Siemens's building-side intelligent controls and services. In October 2026, Voltus raised USD 225 million aimed at making flexibility foundational to the grid. The company said it expects to scale to 20 gigawatts by 2030 as it advances its BYOC program and grows its base of connected batteries.

The Companies Behind the Deal

Voltus operates a DER technology platform and virtual power plant business that connects distributed energy resources to electricity markets, with the stated aim of delivering less expensive, more reliable and more sustainable electricity.
