This 600MW project will be located to the north-west of Loch Lochy in the Great Glen.

The proposed project will include construction of a new dam and upper reservoir at Loch a’ Choire Ghlais (the upper reservoir).

A powerhouse complex would be constructed underground, together with a series of tunnels to provide access and convey water between the lower reservoir (Loch Lochy) and the upper reservoir.

In addition, an outlet area comprising an administration building and jetty, tunnel portals and a tailrace structure would be constructed on the shores of Loch Lochy.

The scheme will help meet peak demand and would extract and store up to 30GWh to help balance supply and demand for power at a national scale.

Upon completion, the scheme will have minimal visual impact in the Great Glen.
