SSE Thermal and Copenhagen Infrastructure Partners (CIP) are developing the new Slough Multifuel facility as a 50:50 joint venture. The facility will produce electricity and heat by burning waste-derived fuels made from various sources of municipal solid waste, commercial and industrial waste, and waste wood.

SSE Thermal's Burghfield Power Station is a 45MW gas-fired embedded power station which was commissioned in 1999. The station generates electricity into the local DNO (SSEN Distribution) network and operates within the GB electricity market as a balancing market unit (BMU).

SSE Thermal's Chickerell Power Station is a 45MW gas-fired embedded power station which was commissioned in 1999. The station generates electricity into the local DNO (SSEN Distribution) network and operates within the GB electricity market as a balancing market unit (BMU).

Aldbrough Gas Storage is a joint venture between SSE Thermal and Equinor and can store around 282 million cubic metres (mcm) of gas. SSE Thermal and Equinor have consent to increase the storage capacity at the Aldbrough site, which has not progressed to date due to market conditions. They have plans to develop one of the world’s largest hydrogen storage facilities.

Tawnaghmore Power Station is a 104MW ‘peaker’ plant. It commenced commercial operation in 2003. The SSE Thermal plant comprises two 52MW gas/oil-fired open cycle unit turbines. Its principal function is to help maintain the security of electricity supply in Ireland’s all-island Single Electricity Market (SEM) by being available to operate on quick response to peaks in national energy demand.

The 1,140MW Seabank Power Station is a flexible gas-fired plant. The station was built in two modules with 'Seabank 1’ (755MW) opening in 2000 and 'Seabank 2 (385MW) opening in 2001. The station is owned and operated by Seabank Power Limited, which is co-owned by SSE and CK Infrastructure Holdings Limited.

SSE Thermal's Rhode Power Station is a 104MW ‘peaker’ plant. It commenced commercial operation in 2004. The plant comprises two 52MW gas/oil-fired open cycle unit turbines. Its principal function is to help maintain security of electricity supply in Ireland’s all-island Single Electricity Market (SEM) by being available to operate on quick response to peaks in national energy demand.

SSE Thermal's 1,180MW Peterhead Power Station is a flexible gas-fired plant. It first became operational in 1982. We are currently exploring redevelopment opportunities for a decarbonised power station at Peterhead, using CCS or hydrogen solutions, to ensure the site can continue to provide essential flexible generation in a net-zero world.

The 840MW Marchwood Power Station is a flexible gas-fired plant. The station began operating in December 2009 and is one of the most efficient gas-fired power stations in the UK. The station is owned by Marchwood Power Limited, a 50:50 joint venture between SSE and Munich Re.

SSE Thermal and Equinor are actively developing Keadby 3, which could become the UK’s first power station equipped with carbon capture technology by the mid-2020s. With an electrical output of up to 910MW, Keadby 3 Carbon Capture Power Station will use natural gas as its fuel and will be fitted with a carbon capture plant to remove the CO2 from its emissions.

SSE Thermal's 460MW gas-fired Great Island Power Station entered commercial operation in 2015, replacing the former oil-fired station at the site. It is now one of the cleanest and most efficient power stations on the island of Ireland, generating enough electricity to power half a million Irish homes.

SSE Thermal's 735MW Medway Power Station is a flexible gas-fired plant. It entered full commercial operation in 1995. SSE Thermal are exploring options to decarbonise our energy generation at Medway through emerging CCS and hydrogen solutions to ensure the site can continue to provide essential flexible power in a net-zero world.

SSE Thermal and Equinor are exploring opportunities for decarbonised power generation at Peterhead, developing plans for a new power station at the site equipped with carbon capture technology.

SSE Thermal’s Keadby 2 Power Station in North Lincolnshire has an efficiency of around 63 per cent, making it the most efficient plant of its type in the UK and Europe - and one of the most efficient in the world. It entered into commercial operations in March 2023.

Deeside Power Station, a decommissioned CCGT in north Wales provides carbon-free inertia to the system. It is operated by Triton Power, which is jointly owned by SSE Thermal and Equinor.

Saltend Power Station is a CCGT (Combined Cycle Gas Turbine) CHP (Combined Heat & Power) power station located on the Humber Estuary in East Yorkshire. The station has an output capacity of 1200 MW providing power to the UK electricity market, and power and steam to the adjacent Saltend Chemicals Park. It is operated by Triton Power, which is jointly owned by SSE Thermal and Equinor.

Indian Queens Power Station is an OCGT (Open Cycle Gas Turbine) power station. The station has an output capacity of 140 MW providing voltage support to the UK electricity market as part of an ancillary services contract with National Grid. It is operated by Triton Power, which is jointly owned by SSE Thermal and Equinor.

The proposed Keadby Hydrogen Power Station could be the world’s first 100% hydrogen-fuelled power station, producing zero emissions at the point of combustion. SSE Thermal and Equinor's proposed Keadby Hydrogen Power Station would have a peak demand of 1,800MW of hydrogen, securing at-scale demand for hydrogen in the region for decades to come.

SSE Thermal and Equinor are developing a first-of-a-kind project which would unite hydrogen production, storage and power generation in one location by the middle of this decade. The Aldbrough Hydrogen Pathfinder aims to produce hydrogen and start filling the cavern by 2025, subject to planning consents and reaching a financial investment decision.

SSE Thermal and Equinor's proposed Aldbrough Hydrogen Storage facility could be in operation by early 2028, with an initial expected capacity of at least 320 Gigawatt hours (GWh), which is enough to power over 860 hydrogen buses a year.

SSE Thermal is proposing that the site of our existing power station in Tarbert will provide the location for a new power station which would run on 100% sustainable biofuel, Hydrotreated Vegetable Oil (HVO), with the potential to utilise hydrogen in the future.

SSE Thermal’s site at Platin provides the location for a proposed new power station and substation which would run on 100% sustainable biofuel with the potential to convert to hydrogen in the future.
