SSE Secures 20-Year CfD for 1.4 GW at Berwick Bank Offshore Wind Project

SSE has secured a 20-year contract for 1.4GW of low-carbon offshore wind power from Phase B of its Berwick Bank Wind Farm project in the UK’s seventh Contracts for Difference (CfD) Allocation Round.

The agreement for Berwick Bank B represents the only Scottish fixed-bottom offshore wind project to secure a CfD in this allocation round. It comes after the Scottish Government approved a consent order in July 2025 covering the offshore wind farm array for the overall project. Under the contract, Berwick Bank B is guaranteed a strike price of £89.49 per MWh for 1,380 MW of offshore renewable generation capacity. The price is set in 2024 terms and will be adjusted annually in line with CPI inflation. This support applies to the low-carbon electricity the project will supply over a 20-year contract period.

Situated in the outer Firth of Forth, about 38 km off the Scottish Borders coast, the Berwick Bank Wind Farm is designed to deliver up to 4.1 GW of offshore wind capacity in total, divided across three broadly similar phases. With Phase B having secured this contract, the remaining A and C phases are eligible to compete in future auction rounds, including the UK’s eighth CfD allocation round, which is anticipated later this year. If developed to its maximum planned capacity, Berwick Bank has the potential to be the largest offshore wind farm globally once completed. Its overall scale means the project would play a key role in increasing Scotland’s renewable energy capacity by almost a quarter, helping provide consumers with more affordable offshore wind power and supporting the UK’s broader clean energy objectives.
