ABB has been commissioned by the Danish energy company Dong Energy to build a 220-kilovolt high-voltage cable system. The system will connect the offshore wind farm Hornsea Project One in the North Sea with the British east coast and supply approximately one million households with wind energy.
The wind farm Hornsea Project One will have an installed capacity of 1.2 GW, making it the largest offshore wind farm in the world. The connection to the wind farm is expected to go into operation in 2019, and the contract has a total value of more than 250 million US dollars.
ABB will be installing undersea AC cable systems for the power grids in the east and west to transmit the energy over a distance of 120 kilometres from the wind farm to the British east coast. The Hornsea offshore wind farm will help the UK achieve its goal for 2020 of having 30% renewable energy in the total amount of energy produced.
It is located approximately 120 km off the coast of Yorkshire and extends over more than 400 square kilometres. Siemens 7.0-MW turbines will be used for Project One Project Two and Project Three are currently in the planning phase. According to Dong Energy, they could add a further 3 GW of capacity.
"Hornsea Project One is a truly groundbreaking project in terms of the amount of power that can be generated, the area it covers and the distance from the coast," said Duncan Clark, Program Director for Hornsea Project One at Dong Energy.
