The final stage in what has been dubbed “the world’s largest offshore wind farm” is the use of 14 megawatt versions of GE Renewable Energy’s giant Haliade-X turbine after a contract to supply them has been confirmed.
In an announcement Tuesday, GE A service and guarantee contract has also been concluded. A total of 87 of its Haliade-X 14 MW turbines are in use at Dogger Bank C, a 50:50 joint venture between SSE Renewables and Equinor that will have an output of 1.2 gigawatts.
This week’s news follows an announcement late last year that GE’s renewable energy business has been selected as the preferred turbine supplier for Dogger Bank C.
Dogger Bank C is part of the larger Dogger Bank wind farm and will complement Dogger Bank A and Dogger Bank B. The latter two projects include SSE Renewables, Equinor and Eni, have the proportions of 40%, 40% and 20%. Dogger Banks A and B will use 190 of GE’s Haliade-X 13 MW turbines.
The size of the Haliade-X turbine is considerable. It will have a top height of 260 meters (853 feet), blades 107 meters long and a rotor 220 meters long.
It is one of several large wind turbines currently being developed. In February, Vestas Plans for a 15 MW turbine announced. Another company Siemens Gamesa Renewable Energyis working on a 14 MW model, the SG 14-222 DD, which can also be increased to 15 MW if necessary.
Large projects, main goals
The Dogger Bank wind farm will be located off the coast in northeast England in the North Sea and will have a total capacity of 3.6 GW. When fully functional, it can provide electricity to millions of households annually. Those behind the project have repeatedly called it “the largest offshore wind farm in the world”.
SSE Renewables will oversee the construction and delivery of the facility, with Equinor – better known as the Oil and Gas Major – assuming responsibility for operations.
If everything goes according to plan, Dogger Bank C turbines will be installed in 2025, with the entire project completed by 2026. An estimated 470 new jobs could be created to support the development of Dogger Bank, according to GE.
The UK has a mature offshore wind sector that is expected to expand in the years to come. The authorities are aiming for a capacity of 40 GW by 2030. The European Union, which left the UK in January 2020, is aiming for 300 GW offshore wind by the middle of this century.
The US still has a long way to go across the Atlantic to catch up with Europe. America’s first offshore wind turbine, the 30 MW Block Island wind farm in Rhode Island waters, only started commercial operation at the end of 2016.
However, the US sector took a big step forward last week after that Authorities gave the green light for the construction and operation of the 800 MW Vineyard Wind 1 project off the coast of Massachusetts.
The US Department of the Interior described the development as “the first major offshore wind project in the US”.
In March, the ministries of energy, home affairs and trade said they wanted offshore wind capacity reach 30 gigawatts by 2030President Joe Biden’s administration hopes to create thousands of jobs and billions in investments in the years to come.
Preliminary figures from the US Energy Information Administration show that the share of wind in supply-scale electricity generation was 8.4% for 2020.
In contrast, the share of natural gas and coal was 40.3% and 19.3%, respectively. Overall, fossil fuels had a share of 60.3%, while nuclear power plants and renewable energies had shares of 19.7% and 19.8%, respectively.
