World’s Largest Offshore Wind Farm Fully Up and Running

Ørsted has commissioned the 1,218MW Hornsea One wind farm off Yorkshire, UK, the world’s largest offshore wind farm.

The last of the 174 Siemens Gamesa 7MW wind turbines were installed at the site some 120 kilometres off Yorkshire in early October.

The wind farm became fully operational at the end of December, Ørsted’s CEO Henrik Poulsen said. The official inauguration is expected in early 2020.

Fred. Olsen Windcarrier’s jack-up vessel Bold Tern installed the first turbine at the wind farm in February 2019. The first power was produced and delivered to the UK grid later that month.

Bold Tern installed 91 turbines, and A2SEA’s jack-up Sea Challenger installed the remaining 83 units.

The wind farm is owned by Ørsted (50%) and Global Infrastructure Partners (50%).

Looking ahead, Ørsted expects to divest the wind farm’s offshore transmission assets by the end of the year.
