The 1.32 GW world's biggest offshore wind farm in UK produces first power

Ørsted announced that the 1.32 GW Hornsea 2 wind project, located 89 km off the UK's east coast has generated the first power.

First power on Hornsea 2 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.

The wind project consists of 165 8 MW Siemens Gamesa wind turbines which will be capable of generating 1.32 GW of clean electricity – taking the title of ‘world’s largest operating offshore wind farm' from its sibling project Hornsea 1. Together, the two projects will be capable of providing enough power for well over 2.3 million homes.
