Great Island Night Cropped


Flexible and efficient thermal generation will play a critical role in the transition to a low-carbon economy, providing reliable capacity at scale in response to market changes and events.

At SSE, our power stations and gas storage facilities complement our renewables assets, ensuring a robust electricity system and safeguarding customers’ power supplies.

In addition to our current development pipeline, SSE has a number of existing sites which are well-placed for the development of further super-efficient CCGTs if required in the transition to a low-carbon energy system.

We’re also excited about the potential of Carbon Capture and Storage technology, which could allow flexible power stations to continue providing large-scale generation with net zero carbon emissions.

By building on SSE’s established skills in asset management and project development, our vision is to become the leading generator of flexible thermal energy in a low-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.
