The Solution to the Power Grid's Woes Might Just Be Sitting in Your Driveway
A new pilot program in Massachusetts is testing vehicle-to-grid (V2G) technology, allowing electric vehicle owners to discharge their batteries to support the power grid during peak demand. This initiative aims to improve grid reliability and lower costs by leveraging the growing number of EVs as decentralized energy storage.
Why it matters
V2G technology could be a critical solution for managing energy demand as utilities transition to intermittent renewable energy sources like wind and solar.
Utilities across the country are pursuing pilot projects for the tech, figuring out how to coordinate hundreds, thousands, and eventually millions of EVs. To that end, today a coalition of companies—Eversource, National Grid, EnergyHub, Sunrun, and the Mobility House—is launching an early test of the technology in Massachusetts so utility customers can give it a try. Lessons learned here and elsewhere could drive the technique into the mainstream, making the grid more reliable and electricity cheaper, even if you don’t own an EV. “It’s great to have Massachusetts stepping into the lead here and doing this because these learnings are what’s going to allow this technology to scale,” said Chip Silverman, director of grid services at Sunrun, a solar and battery company.
