The 1.2 GW Hornsea One project is located 120 kilometres off the coast of Yorkshire, UK, and covers 407 square kilometres. When complete, the offshore wind farm will be the largest offshore wind farm in the world, almost double the capacity of the present record holder, the London Array offshore wind farm. Hornsea One will be able to supply electricity to approximately 800,000 British households.
Siemens has now been chosen to supply 171 7.0 MW wind turbines for the project, subject to signing of contracts and DONG Energy making its final investment decision, which is expected in late 2016.
“Our decision to make Siemens the preferred supplier for our Hornsea Project One wind farm is a crucial step in our efforts to lower cost of electricity” said Mats Vikholm, Senior Vice President, DONG Energy Wind Power. “The 7 MW turbine is an upgrade of the 6 MW platform which we know very well from Westermost Rough in the UK and Gode Wind 1+2 in Germany. Larger and more cost efficient wind turbines are key to reach our strategic target of reducing cost of electricity from offshore wind to 100 euros per MWh in 2020. The decision by Siemens to open new production facilities in Hull on the British east coast is a key factor in bringing down the cost of wind turbines for this project. This preferred supplier agreement will both help reduce the cost of offshore wind and create and retain real jobs in UK.”
Siemens turbines will also be deployed at Race Bank and Walney Extension Phase 2, announced earlier this year. DONG Energy has signed a contract with Siemens for 91 6 MW turbines to be deployed at Race Bank. These turbines have performance enhancing features that will deliver a total capacity of up to 580 MW. A second contract has been signed for Walney Extension Phase 2 for the 7 MW turbine, subject to DONG Energy making a final investment decision.
Michael Hannibal, CEO Offshore of the Wind Power and Renewables Division at Siemens, added that the advanced model of the company’s direct drive wind turbine, with an output of 7 MW, will leverage Siemens energy output of Walney Extension Phase 2 and Hornsea Project One, thereby contributing to lowering the cost of electricity. These activities will be supported by the company’s new wind turbine factory in Hull, further promoting the growth of the UK offshore wind industry.
