Orsted moved to cement a leadership role in US offshore wind with a $510m acquisition agreement for Deepwater Wind, the Rhode island-based pioneer in the sector that has 3.3GW of potential capacity off the East Coast.

The purchase from current Deepwater owner, the investment group DE Shaw, turbocharges Orsted’s existing US operations, which already include a 5.5GW development portfolio off Massachusetts and New Jersey, and gives the Danish group a route to supply offshore wind energy to seven states.
