Massachusetts: Parked EVs Will Start Feeding The Grid This Summer
After the school year ends in the Massachusetts towns of Acton and Boxborough, the district’s electric buses will mostly stay put in a parking lot. But they won’t sit idle all summer.
The three vehicles will charge up their nearly 200-kilowatt-hour batteries overnight, when the power supply is at its cleanest and cheapest, then send energy back to the grid from 4 p.m. to 7 p.m. on days when the grid is strained. The district will earn revenue for the power it shares, perhaps even enough to cover the costs of charging up during the school year, says Kate Crosby, energy manager for the Acton-Boxborough school district.
