Avangrid Renewables plans to develop its 2.4GW Kitty Hawk offshore wind complex off the coast of North Carolina in three 800MW stages through to 2029, to supply consumers in the PJM Interconnection, the largest US competitive wholesale electricity market.

The developer will site the mega-project – the nation’s second-largest planned offshore wind array after Dominion’s 2.64GW Coastal Virginia Offshore Wind (CVOW) – in a 495-square-km (112,405 acre) lease area 43km (27 miles) off the coast.
