The acquisition is an important milestone in ENGIE’s ambitions for flexible generation and storage across the UK.

ENGIE has announced its acquisition of a fully permitted 50 MW Battery Storage site in Cathkin, Scotland, from a joint venture between ILI Group, Abbey Group, and YOO Energy.

Storage technologies are already playing a critical role across the GB grid, providing balancing services to the system operator, whilst helping to manage the intermittent nature of wind and solar generation. Alongside increasing levels of clean renewable generation, battery assets such as Cathkin will enable the transition towards a zero carbon power system across Great Britain.

The project is set to be completed, with the battery being energised, by July 2024.

ENGIE already has a strong position in energy storage and flexibility in the UK, with 2.1 GW of pumped storage hydro capacity and 11 GWh of associated stored energy. This battery project will be a significant addition to ENGIE’s existing renewables assets and storage ambitions.

“Energy storage is a fundamental pillar in the energy transition, playing a major role in unlocking renewable energy’s full potential. With renewable energy taking a more prominent role in the UK power generation mix, storage projects such as this will help ENGIE contribute to the grid’s stability, flexibility and reliability” said Kevin Dibble, ENGIE’s UK Country Manager.
