Partnership with EnergyHub, Sunrun, & The Mobility House to Test Massachusetts Residential Vehicle-to-Grid Program for Eversource & National Grid Customers

Eversource and National Grid are testing a new option for Massachusetts homeowners with certain electric vehicles: getting paid to send power from your car battery back to the grid. The utilities are teaming up with EnergyHub, Sunrun, and The Mobility House to add this "vehicle-to-grid" (V2G) capability to the existing ConnectedSolutions program, which already pays customers for letting the utility tap into smart thermostats and home batteries during times of high electricity demand.

If your EV supports bidirectional charging (meaning it can both draw power and send it back), enrolling would let the utility draw on your parked car's battery during peak demand periods, similar to how it already uses home batteries. In exchange, you'd earn incentives, though the announcement doesn't specify dollar amounts. The idea is that with more than 150,000 EVs already registered in Massachusetts, and more bidirectional-capable models hitting the market, all those parked cars represent a large pool of untapped battery storage that could help keep the grid stable and potentially hold down costs for everyone.

This is still a pilot program, not yet available broadly, and it builds on related work National Grid and Eversource are doing with school bus fleets. For homeowners in Eversource or National Grid territory who already own or are considering a V2G-capable EV, this signals that a residential incentive program may become available. Details on eligibility and payment amounts weren't included, so anyone interested would need to check the ConnectedSolutions program pages directly as the pilot develops.
