Coire Glas hydro scheme

About Coire Glas

Coire Glas is the first large scale pumped hydro storage scheme to be developed in the UK for more than 40 years. It is located on the shores of Loch Lochy in the Scottish Highlands, between Fort William and Inverness and has a potential capacity of up to 1500MW. It will double Great Britain’s existing electricity storage capacity, providing homegrown renewable energy when the demand is high or other variable generation is low.

We are currently investing £100 million to further develop Coire Glas and, once the initial works are complete, we will see over £1.5 billion invested into the project.

Once operational, Coire Glas will be able to generate enough power for 3,000,000 homes in just 5 minutes.

The project has received planning consent from the Scottish Government in 2020 and will play an essential role in decarbonising the UK’s electricity supply and will be key to delivering net zero.
