Overall, SSE Renewables has secured provisional contracts for just over 890MW* of pumped storage and hydro capacity for the delivery year 2024/25, as well as a 15-year contract for 3MW* at its Gordonbush Extension onshore wind project, currently under construction in the Scottish Highlands.
The provisional results of the latest T-4 capacity auction in Great Britain were published on Wednesday 10 March, with a total of 40.8GW in capacity contracts awarded to electricity generators at an auction clearing price of £18/kW.

The Gordonbush Extension wind farm development, currently under construction around 9.5km west of Brora in Scotland, secured 2.968MW of provisional capacity for a period of 15 years. The wind farm will consist of 11 Siemens Gamesa wind turbines generating up to 38MW of wind powered electricity and is scheduled to be operational in mid-2021. The development is the first to be built by SSE Renewables on a merchant basis, which means no subsidies were used to assist with its funding.
The provisional results are subject to confirmation by the Secretary of State for Business, Energy and Industrial Strategy (BEIS).
*A de-rating factor is applied to all capacity according to rules set by the UK Government.
