Google and Voltus collaborate to create a 1-gigawatt virtual power plant using aggregated flexible energy assets, enhancing grid reliability for 67 million people across 13 states and Washington, D.C.

Google and energy technology company Voltus have announced an expanded partnership to build a 1-gigawatt (GW) virtual power plant within the PJM grid region, which supplies electricity to approximately 67 million people in 13 states plus Washington, D.C. This initiative is an extension of an earlier agreement announced earlier in 2026, which had targeted a 100-megawatt capacity. The current expansion represents a tenfold increase in capacity and is considered one of the largest distributed energy resource portfolios deployed by a hyperscale technology company to date.

The virtual power plant concept involves aggregating flexible electricity capacity from a wide range of sources, including smart thermostats, batteries, and industrial equipment located in homes and local businesses. By coordinating these diverse resources, the project can collectively reduce energy consumption during periods of peak demand, thereby supporting the stability and reliability of the regional power grid.

Participants contributing assets to the virtual power plant benefit economically through direct financial incentives such as bill savings and cash payments. Google's funding enables the aggregation and coordination of these distributed energy resources, reflecting a strategic commitment to enhancing local grid capacity, reliability, and affordability.

This approach represents an innovative integration of technology and energy management, leveraging digital tools and flexible load resources to address grid challenges in a sustainable manner. By expanding from 100 megawatts to 1 gigawatt, Google and Voltus demonstrate the scalability of virtual power plants and their potential role in modernizing electrical grids to better serve large populations.

The project highlights the evolving landscape of energy infrastructure, where collaborations between technology giants and energy service providers aim to increase the efficiency and resilience of power systems. While still growing, virtual power plants like this could become critical in balancing supply and demand while facilitating the integration of renewable energy sources in the future.
