TotalEnergies and Duke Energy have secured seabed leases in the Carolina Long Bay lease auction after pledging to spend a combined $315m in fees.
The French developer secured the western 55,937-acre zone for $160m following 18 rounds of bidding.
Duke meanwhile landed the eastern 55,154-acre site for $155m, marking its entry into offshore wind.
Both zones collectively can support up to 1.3GW of power, according to BOEM, although the final capacity may be higher.
Before the leases are finalised, the Department of Justice and Federal Trade Commission will conduct an anti-competitiveness review of the auction, and the provisional winners will be required to pay any balance on the winning bids and provide financial assurance to BOEM.
