Deepwater Wind submitted a proposal to build an offshore wind energy storage project off New Bedford, Mass., with Tesla Inc., the wind developer announced July 31. The Revolution Wind farm would be a 144-MW offshore wind farm paired with a 40-MWh battery storage system from Tesla. The project was submitted under Unitil Corp., National Grid USA and Eversource Energy Service Company, Inc.'s request for proposals for renewable energy projects under the state's 2016 Act to Promote Energy Diversity.
Deepwater Wind has also submitted alternative bids for a 288-MW version and a 96-MW version of the Revolution Wind project.
"Revolution Wind is flexible and scalable. That's a serious advantage of offshore wind — we can build to the exact size utilities need," Deepwater Wind CEO Jeffrey Grybowski said in a statement. "We can build a larger project if other New England states want to participate now or we can start smaller to fit into the region's near-term energy gaps. And our pricing at any size will be very competitive with the alternatives."
The project will be built 12 miles south of Martha's Vineyard, adjacent to Deepwater Wind's 90MW South Fork Wind Farm. If approved, construction would begin in 2022 and the project would start operations in 2023. Deepwater Wind has begun surveying the lease site for the Revolution Wind project.
Submissions for the RFP were due July 27. There had been 18 other notices of intent to bid, including Apex Clean Energy, Calpine Corp. and Brookfield Renewable Partners LP.
Deepwater Wind also plans to submit an offshore wind proposal under a separate Massachusetts RFP, part of the state's mandate for utilities to purchase offshore wind power. The company's 30-MW Block Island Wind Farm off Rhode Island, which came online in December 2016, is the first U.S. offshore wind farm in operation.
