Deepwater CEO Jeff Grybowski said the proposed 144-megawatt development would stockpile electricity produced at night and deliver it to the grid when most needed.
Deepwater submitted its bid for the project in response to a request from National Grid Plc (NGG) , Unitil Corp (UTL - Get Report) and Eversource Energy (ES - Get Report) for about 9.45 million megawatt-hours of annual clean energy supply. Massachusetts is set to award the bids in December and make them public this week.
The contracts require most energy to be delivered during late winter afternoons and evenings. The Tesla batteries will ensure that Deepwater wind turbines can efficiently send energy to the mainland during those times.
Tesla shares traded down slightly in early afternoon treading.
