The world’s largest offshore wind farm is now fully operational

The world’s largest single offshore wind farm, Hornsea 2 in the UK, is now fully operational.

Update August 31: August 17th, electric reported that Hornsea 2 is expected to be fully commissioned by the end of August. Ørsted slipped in for a home run today, the last day of the month. Hornsea 2 has been completely powered up.

Electrek’s take: This is a major milestone for offshore wind and renewable energy in general, not only in the UK but globally. Ørsted alone, not counting other offshore wind developers around the world, has 8.9 gigawatts (GW) of offshore wind power in operation, about 2.2 GW under construction and about 11 GW more capacity under development. . Ørsted’s goal is to install 30 GW of offshore wind power globally by 2030.

Now that the Biden administration’s Inflation Reduction Act has been passed, major offshore wind projects will start even more quickly in the United States, in new areas such as the Gulf of Mexico, the Gulf of Maine and off the coast of California.

We are already seeing alarming evidence of global warming. The offshore wind revolution will never happen fast enough to prevent deterioration. So it’s heartening to see such a large-scale project come online.

Map: Hornsey Project

At 1.32 GW, Hornsea 2 will overtake Hornsea 1 at 1.2 GW to operate the world’s largest offshore wind farm. It measures 462 square kilometers (178 square miles) and can power more than 1.3 million homes. Together, Hornsea 1 and 2 can power 2.5 million homes.

The 2.8 GW Hornsea 3 depicted in the map above is set to follow in the future as it won a differential contract from the UK government in early 2022. The Hornsea project is off the east coast of England.

Hornsea 2 is equipped with 165 Siemens Gamesa 8 megawatt (MW) turbines. Most of the wind turbine blades were manufactured at the Siemens Gamesa plant in Hull. One turn of her wind turbine blades could power the average UK home for her 24 hours a day.

Hornsea 2 is home to the world’s largest AC offshore substation, as well as a Reactive Compensation Station (RCS). The length of the cable requires RCS and thus compensates for reactive power loss to ensure transmission efficiency.

As electric On December 16, 2021, Hornsea 2 produced its first electricity production that month, according to a report. But according to Ørsted’s 2021 annual report:

Hornsea 2 progressed as planned until mid-December. However, due to the accelerated infection rate of the Omicron variant, the ships used for commissioning operations could not be deployed as planned.

As a result, the launch of huge offshore wind farms has been delayed until now.

There are other large offshore wind projects in the pipeline, such as Ørsted’s Greater Changhua 1 & 2a in Taiwan, which are also scheduled to commission this year.

Equinor and SSE’s 4.8 GW Dogger Bank off the coast of Yorkshire, UK, is expected to become the world’s largest offshore wind farm by 2026.
