Dogger Bank Wind Farm is a group of offshore wind farms under construction 130 to 200 kilometres off the east coast of Yorkshire, England in the North Sea. It is considered to be the world's largest offshore windfarm. It was developed by the Forewind consortium, with three phases envisioned - first phase, second phase and third phase. In 2015, the third phase was abandoned, while the first and second phases were granted consent. It was initially expected that the Dogger Bank development will consist of four offshore wind farms, each with a capacity of up to 1.2 GW, creating a combined capacity of 4.8 GW. As of 2023, a total of 277 turbines are expected to be built and produce a capacity of 3.6 GW, enough to power 6 million homes.

Hornsea Wind Farm is a Round 3 wind farm which began construction in 2018. Sited in the North Sea 120 km (75 mi) off the east coast of England, the eventual wind farm group is planned to have a total capacity of up to 6 gigawatt (GW).
