Offshore wind developers have been pressured by rising raw material and component costs, and higher borrowing costs, which has cast doubt over the viability of many projects. Indeed, Reuters reported that some projects planned for the waters off the coast of New York may need to be reconsidered in light of the authorities' decision.

"Sunrise Wind's viability and therefore ability to be constructed are extremely challenged without this adjustment," Orsted told Reuters.

Sunrise Wind is an offshore project with a planned capacity of 924 MW that could supply electricity to 600,000 households. According to Orsted, it would also involve several hundred million dollars in investments in the state and 800 jobs.

"These projects must be financially sustainable to proceed," the president of Equinor Renewables Americas told Reuters, referring to the offshore wind projects the Norwegian energy major is leading in the U.S.

Per Reuters, Equinor is involved in three projects with BP—the 816 MW Empire Wind 1 and the 1.26 GW Empire Wind 2, as well as the Beacon Wind farm, with a projected capacity of 1.23 GW.
