Danish developer Orsted is at full steam building the world’s largest offshore wind farm, Hornsea 1 in the UK North Sea, with 100 of its 174 Siemens Gamesa 7MW turbines now installed.

The 1.2GW development, which started producing power earlier this year, will ultimately supply electricity to over one million British homes.

Operations have been ramping up at the wind farm, located 120km off England's northeast coast — the farthest from shore a wind farm has ever been built — with first operational crews sailing out earlier this month. Final commissioning is slated for 2020.

Hornsea 1's reign as the world's largest offshore wind project will be short-lived. Orsted's 1.4GW Hornsea 2 is due to enter service by 2022.
