DONG Energy will build the giant Hornsea Project One offshore wind farm, capable of powering well over 1 million UK homes, off the Yorkshire coast after taking a final investment decision.
With a capacity of 1.2 gigawatts (GW), Hornsea Project One will be the world's first offshore wind farm to exceed 1 GW in capacity and will become - by a considerable margin - the world's largest offshore wind farm.
Vote of confidence
Secretary of State for Energy and Climate Change Amber Rudd said: "Thanks to Government support the UK is the world leader in offshore wind energy and this success story is going from strength to strength.
"DONG Energy'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.
"This project means secure, clean energy for the country, jobs and financial security for working people and their families, and more skills and growth boosting the Northern Powerhouse."
Once completed, Hornsea Project One will be able to meet the electricity needs of well over 1 million UK homes.
It will be located 120 kilometres off the Yorkshire coast - further than the distance from Leeds to Liverpool.
The project has the potential to create around 2,000 jobs during its construction phase with up to 300 additional jobs supported directly and indirectly throughout its operational phase.
Hornsea Project One will span a huge area of approximately 407 square kilometres, which is over five times the size of the city of Hull.
The offshore wind farm will use 7 megawatt (MW) wind turbines, with each one 190 metres tall - larger than the Gherkin building in London.
As part of the project, DONG Energy will construct the longest ever offshore wind farm high voltage AC electrical system in the world.
It will take the clean electricity produced by the wind turbines, transmit it to shore and then feed it into the national grid.
This system includes more than 900 kilometres of cables, enough to stretch from Land's End to John O'Groats.
DONG Energy is the sole owner of Hornsea Project One after acquiring the 66.66% ownership share of SMart Wind in February 2015.
DONG Energy also has the project rights to Hornsea Project Two and Hornsea Project Three, which have the potential of 3 GW of offshore wind power capacity in total.
The RYA believes that the impact that offshore wind farms have on navigational safety for recreational boating can be minimised provided developers fully address navigational safety issues of concern to the RYA.
The RYA continues to monitor the developments in Round 3 wind farms and Round 2 extensions, assessing their potential impact on recreational boating.
We also meet regularly with developers to discuss recreational navigational safety.
Hornsea Project One is expected to be fully commissioned in 2020.
