The project forms part of the larger East Anglia Offshore Wind Zone, where 7.2GW of renewable power capacity is proposed to be installed in an area of 6,000km² off the coast of East Anglia.
The onshore construction works of East Anglia ONE started in early-2017, followed by the offshore construction works in 2018. The wind farm is anticipated to generate first power in 2019 and be fully-operational by 2020.
The UK offshore wind farm is expected to generate approximately 3,000 construction jobs, while the output from the project will be sufficient to serve approximately 500,000 UK homes. The completion of the later phases will further enable it to serve approximately 700,000 homes.
The project is expected to be the most cost-effective offshore wind farm in the UK, with the cost of electricity set at £119 ($177) per megawatt-hour based on the successful bid by ScottishPower Renewables in the CfD auction held by DECC in February 2015.
The project will also help the UK achieve its target of reducing greenhouse gas emissions by 34% by 2020 and at least 80% by 2050 as part of its Climate Change Act 2008.
