Hywind Maine

Statoil grant proposal

Thu, 12/13/2012 - 4:00pm
  • The Hywind Maine pilot project will demonstrate the commercial potential of floating offshore wind turbine technology and is in response to a Request for Proposals issued by the Maine Public Utilities Commission
  • The project consists of four floating 3 MW turbines that will be anchored to the sea floor in deep ocean waters in the Gulf of Maine. Electricity generated will be transmitted via an underground cable to on land energy transmission lines.
  • Contract terms with the Maine Public Utilities Commission for connection to the Maine grid and sale of electricity to Maine utilities have yet to be agreed upon. The project proposes to connect into the CMP 34.5 kV Boothbay substation.
  • The lease site is a 22 square mile, 4-block area in federal waters about 12 nautical miles off Boothbay Harbor
  • The U.S. Bureau of Ocean Energy Management is the federal agency responsible for approving the site lease and consults with federal, state, tribal and local government agencies, commercial and recreational interests and the public in making its decision. An environmental impact statement, which includes public hearings, is a requirement of the leasing process.
  • The environmental review process will begin when Statoil submits a construction and operations plan to BOEM.
