DONG Energy to build largest offshore wind farm

The world’s largest offshore wind farm is to be built off the UK’s coast by DONG Energy, Denmark. 

With a 1.4 gigawatt (GW) capacity, the Hornsea Two wind power project will be built 89 kilometres off the Yorkshire coast and supply energy at a guaranteed price of £57.50 per megawatt hour (MWh). This price – 50% lower than prices allocated to new offshore wind farms two years ago at auction – is the result of the UK’s contract for difference (CfD) system, which sees projects guaranteed a minimum selling price for electricity. 

DONG is in the process of building Hornsea One, an offshore wind farm with a 1.2GW capacity. Together, Hornsea One and Two –with the latter expected to be operational from 2022 with a lifespan of 25 years – will form the largest offshore wind farm. 

The low guaranteed price for power from wind farms, compared to the £92.50 for a new nuclear power station at Hinkley Point, saw the Green Party claim this should spell the end of nuclear power. 

Matthew Wright, Managing Director for DONG Energy UK, commented, ‘This is a breakthrough moment for offshore wind in the UK and a massive step forward for the industry. Not only will Hornsea Project Two provide low cost, clean energy to the UK, it will also deliver high quality jobs and another huge boost to the UK supply chain.’ DONG Energy claim the construction phase will support over 2,000 workers, with 130 permanent jobs when operational.
