Breadalbane hydro scheme
The Breadalbane hydro scheme is set in the mountainous region around Loch Lyon, Loch Tay and Loch Earn in Perthshire.
Investing £70m in Lochay Power Station
We are investing £70 million over the next three years to repower Lochay Power Station, ensuring it can play a role in Scotland’s energy system for decades to come.
The project involves the replacement of all main components inside the station with modern, efficient technology, extending the power station’s operational life by at least 40 years.
Located in Killin, Perthshire, Lochay Power Station was commissioned in 1958 and is the largest and highest producing hydro power station in SSE Renewables’ Breadalbane scheme.
Main construction works will start in April 2025 and are expected to complete in 2028, coinciding with the power station’s 70th anniversary.
