The US Department of the Interior (DOI) on Friday announced the results of the nation’s “highest-grossing” offshore energy lease sale, with six leases spread over some 490,000 acres awarded to developers, which spent a combined record $4.37bn on the bids.

The history-making tender, said the DOI, was “a major milestone” towards achieving the Biden-Harris administration’s goal of reaching 30GW gigawatts of offshore wind plant by 2030.

The winners were: RWE-led Bight Wind, EDP Renewables-Engie joint venture Ocean Winds, EnBW-led Attentive Energy, Shell-EDF joint venture Atlantic Shores, Invenergy, and Copenhagen Infrastructure Partners (CIP)-led Mid-Atlantic Offshore Wind.
