LITwSSE Thermal


We believe flexible and efficient thermal energy will play a critical role in the transition to a net zero future, complementing renewable generation and maintaining security of supply.

In SSE Thermal, we own and operate an industry-leading fleet of Flexible Generation, Energy-from-Waste, and Energy Storage assets across the UK and Ireland.

Through new projects like our 840MW Keadby 2 CCGT in North Lincolnshire, we’re displacing older, less-efficient generation, and playing a key role in the energy transition. When completed, Keadby 2 is expected to be the cleanest and most efficient gas-fired power station in Europe.

But we want to go further. We’re exploring ways to fully decarbonise our thermal assets through emerging opportunities in carbon capture, usage and storage (CCUS) and hydrogen.

We’re already looking at the potential to develop new projects where we can deploy these technologies, with options at several of our existing sites. We will not develop any further gas-fired power stations unless they have a clear route to decarbonisation.

By building on our established skills in asset management and project development, our vision is to become the leading generator of flexible thermal energy in a zero-carbon world. 

Flexible Generation Cropped

We currently own and operate five of the most flexible and efficient gas-fired power stations in the UK and Ireland.

We’re now investing £350m to construct our new 840MW Keadby 2 project in Lincolnshire, which is expected to be the cleanest and most efficient CCGT in Europe.

Energy From Wast Cropped

We’re developing new energy-from-waste projects, including Ferrybridge Multifuel 2 (FM2), a £325m joint investment between SSE and Wheelabrator Technologies.

FM2, combined with the existing FM1 facility, will divert an estimated 1.3m tonnes of waste from landfill.

Gas Storage Cropped

We hold around 40% of the UK’s conventional gas storage capacity at our Aldbrough and Atwick sites on the East Yorkshire coast.

These sites offer valuable flexibility and hedging services to the UK and interconnected gas markets.
