Floating wind development in the windswept reaches of the Gulf of Maine made headway this month with five developers submitting project proposals, including US-market big-hitters Avangrid, Mainstream and TotalEnergies.

The proposals were in response to a request for interest (RfI) by the Bureau of Ocean Energy Management (BOEM), the regulator of energy development in federal waters, to assess commercial interest in the Gulf of Maine offshore wind planning area.
