The Seagreen Offshore Wind Farm has transitioned from construction into full commercial operation, becoming one of the UK’s largest offshore renewable energy assets. Located in the North Sea off the Angus coast, the 1.1GW project now supplies enough renewable electricity to power more than 1.6 million homes while supporting Scotland’s wider offshore wind ambitions.
Seagreen Offshore Wind Farm Current status update (2026)
As of 2026, Seagreen remains fully operational after all 114 turbines entered commercial service in October 2023. The wind farm continues generating renewable electricity from its offshore base in the North Sea and is operated by SSE Renewables on behalf of the ownership consortium comprising SSE Renewables, TotalEnergies and PTTEP.
The project also serves as an important benchmark for Scotland’s expanding offshore wind sector. The Scottish Government’s recent approval of the 2GW Caledonia Offshore Wind Project demonstrates how newer developments are building on the experience gained during Seagreen’s construction and operation. Caledonia is expected to become another flagship offshore project in the Moray Firth, strengthening Scotland’s renewable energy capacity and creating new construction opportunities across the supply chain.
Although Seagreen has achieved full operational status, industry attention has shifted toward improving electricity transmission capacity. Grid constraints have occasionally limited the amount of renewable power delivered to consumers, reinforcing the need for continued investment in Britain’s transmission infrastructure alongside new offshore wind developments.
Development of the project
SSE Renewables (49%) and TotalEnergies (51%) are partners in the GBP 3 billion Seagreen wind farm. With the help of TotalEnergies, SSE Renewables is driving the development and construction of the Seagreen project, which will be operational for the next 25 years.
In 2019, the project was awarded a 454MW 15-year CfD contract, and on June 3, 2020, the project received the Final Investment Decision. Seagreen offshore wind farm will be completed with a capacity of 1,075MW (up to 114 turbines).
The offshore wind farm is expected to begin commercial operations in 2023, with the first power expected earlier in the same year.

Significance of the Seagreen offshore wind farm
Seagreen will generate enough green energy to power over 1.6 million homes, the equivalent of two-thirds of all residences in Scotland. Every year, Seagreen will also displace over 2 million tonnes of carbon dioxide from fossil-fuel-generated power. This will be the same as reducing more than a third of Scotland’s annual car emissions and contributing significantly to Scotland’s net-zero aim by 2045.
Seagreen also has a substantial economic impact on Scotland and the United Kingdom. The low-carbon project is boosting Scotland’s green economy and creating high-value green jobs, including a direct contractor, and supply-chain positions.
