First power on Hornsea 2, which is located 89 km off the UK’s east coast, was achieved after its offshore substation (OSS), the world’s largest offshore AC substation, and reactive compensation station (RCS), were installed in late October 2021. Once Hornsea 2 is completed, power will be transferred from the 165 wind turbines via 373 km of array cables to the OSS and RCS, reaching the national grid via 390 km of offshore and 40 km of onshore export cables which terminate at the onshore substation in Killingholme. Hornsea 2’s 165 8 MW Siemens Gamesa wind turbines will be capable of generating 1.32 GW of clean electricity. Together, the two projects will be capable of providing enough power for well over 2.3 million homes.
