SSE and RWE npower renewables are already developing the 500 MW Greater Gabbard offshore wind farm in the outer Thames Estuary and in December 2009 SSE entered into an agreement with DONG Energy to acquire a 25.1% stake in the 367 MW Walney offshore wind farm in the Irish Sea, which is expected to become operational next year.
