SSE investigates Seagreen extension

SSE is exploring an extension to the Seagreen Phase 1 (Alpha and Bravo) offshore wind farm.

The Seagreen offshore wind farm, located in Scottish waters in the Firth of Forth, is a joint venture between SSE Renewables and Total.

According to the Seagreen Design Statement, the wind farm has consent for up to 150 offshore wind turbines but only 114 turbines on three legged steel jackets, each installed on suction bucket caissons are contracted for installation as part of the Seagreen Phase 1 offshore wind farm.

The remaining 36 turbines could be built as an extension. According to the Design Statement, these turbines will be installed on pin-piles steel jackets with up to four legs. Approximately 55km of inter-array cables will be required to connect the turbines and an offshore substation platform.

Upon reaching financial close for the first for the £3bn 1,140 MW phase on 3rd June 2020, Total acquired ownership of 51% of shares in Seagreen Phase 1. The purchase agreement also covers a potential extension opportunity of up to 360 MW.

SSE has said: "we are exploring opportunities for siting these additional turbines, but this is at early stages with no decisions made on timing".

SSE Renewables is leading on the development and construction of the first 1,140 MW phase, supported by Total, and will operate the asset on completion, which is expected in 2022/23. The project will feature 114 MHI Vestas V164-10 MW turbines.

SSE Renewables is also developing its Seagreen 2 and 3 projects (combined up to 3,200MW), which were awarded exclusive development rights by The Crown Estate in 2010. It has also started onshore construction on the world’s largest offshore wind farm, Dogger Bank Wind Farm, which it is delivering together with its partner, Equinor.
