Orsted’s 1,200 MW wind farm off Yorkshire is fully operational

Ørsted has officially commissioned the 1,218MW Hornsea One wind farm off Yorkshire, UK, and it is currently the world’s largest offshore wind farm in terms of installed capacity.

Containing 174 wind turbines, made by Siemens Gamesa (SGRE) and each capable of generating 7 MW of power, the site finished its installations in early October of last year. The site is located about 120 kilometers off the Yorkshire coast and is now officially commissioned, set to be inaugurated next.

With a capacity of 1.2 gigawatts (GW), Hornsea One will be the world’s first offshore wind farm to exceed 1 GW in capacity.

Located off the Yorkshire coast, Hornsea One will span a huge area of approximately 407 square kilometers, which is over five times the size of the nearby city of Hull. For perspective, each turbine is 190 meters tall – larger than the Gherkin building in London.

The wind farm became fully operational at the end of December, Ørsted’s CEO Henrik Poulsen said in a company statement. 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 88 turbines, and A2SEA’s jack-up Sea Challenger installed the remaining 86 units. The wind farm is owned by Ørsted (50%) and Global Infrastructure Partners (50%).

Looking ahead, Ørsted—which was recently named the world’s top sustainable company at the Davos 2020 conference—expects to divest the wind farm’s offshore transmission assets by the end of the year. It also announced recently it will become carbon neutral within the next five years.

  1. Unfortunately, 1200 mw is half the output of the Luminate Generation nuclear plant near Glen Rose, Texas running two ea 1.225gw units. The entire facility takes up about 1/5 the land/sea area and produces reliable power 24/7. Until renewable energy sources (wind/solar) can come close to existing base load units (coal/nuclear) we will continue to need these sources as vital power supplies for an extended period of time. If we’re looking for clean sources that can easily produce base load look no further than nuclear.
