Peterhead originally consisted of two 660 MW conventional steam turbines (units 1 and 2) fired by fuel oil or natural gas. In 1998 work began to convert unit 1's steam turbine into a combined cycle unit with three new gas turbines and HRSG units. The combined-cycle unit was completed in 2000, and two separate gas turbines (units 3 and 4) originally built in 1992 were retired.[1][2]

Under the EU's Industrial Emissions Directive (still effective after the United Kingdom left the EU[3]), plants not meeting pollution limits would have to perform upgrades or opt-out and retire by 2023. Peterhead unit 2, already mothballed, opted out and would have to close in 2023.[4] Plans for its closure began as early as 2010[5], though, and SSE reliquished its unit 2 Transmission Entry Capacity (TEC) rights in 2010.[6] Unit 1 remained in operation, although in their 2013 annual report SSE wrote: "Peterhead technically has an installed capacity of 1,840MW. However, because of the impact of high transmission access charges in the north of Scotland, SSE took the decision in March 2010 to release TEC at Peterhead, effectively constraining the available generation capacity of the site to 1,180MW. Transmission access charges continue to be excessively expensive in the north of Scotland and, given the challenging market conditions for gas-fired generation, SSE has decided to reduce Peterhead’s TEC to 400MW from 31 March 2014."[7]

In 2021 the project applied for 1,180 MW existing generation in the T-4 Capacity Market 2024-2025 auction, and they were listed in the final results.[8][9] This would qualify them for government subsidies to guarantee electricity supply.[10]
