DONG Energy is to go ahead with construction of what will become the world’s largest offshore wind farm.
Spread over 407 square kilometres, it will have a capacity of 1.2 GW, making it the first offshore wind farm to exceed 1 GW.
It will be powered by 7 MW turbines from Siemens – each one 190 metres tall – which will be manufactured at Siemens’ new turbine production facilities in Hull.
UK infrastructure company Balfour Beatty has won a £25m deal for the construction of the onshore substation, and as part of the project DONG will also build the longest offshore wind farm high voltage AC electrical system in the world, expected to be 900 kilometres.
Brent Cheshire, DONG Energy UK’s chairman, said Hornsea was “ground-breaking and innovative” and would power “more homes than any offshore wind farm currently in operation”.
“We are making a major financial investment to construct this giant wind farm and this underlines our commitment to the UK market. Hornsea Project One will support the supply chain and help create local jobs. To have the world’s biggest ever offshore wind farm located off the Yorkshire coast is hugely significant, and highlights the vital role offshore wind will play in the UK’s need for new low-carbon energy.”
UK Energy Secretary Amber Rudd said that DONG’s investment “shows that we are open for business and is a vote of confidence in the UK and in our plan to tackle the legacy of under-investment and build an energy infrastructure fit for the 21st century”.
Hornsea Project One is expected to be fully commissioned in 2020.
