The federal energy regulator in US coastal waters is proposing sweeping rule changes aimed at streamlining the costly and cumbersome offshore wind permitting process, a move it claims will save the industry $1bn over 20 years, the Department of Interior (DoI) announced.

DoI said the proposed changes “would modernise regulations, streamline overly complex and burdensome processes, clarify ambiguous provisions and enhance compliance provisions in order to decrease costs and uncertainty associated with the deployment of offshore wind facilities.”

Interior Secretary Deb Haaland said, “Updating these regulations will facilitate the safe and efficient development of offshore wind energy resources, provide certainty to developers and help ensure a fair return to the US taxpayers.”
