A sizeable hydro-power station located at the entrance to Glen Lochay, 2 miles (3 km) northwest of Killin in NE Stirling Council Area, Lochay Power Station is the largest in the Breadalbane Hydro-Electric Power Scheme. Completed in 1958, the station contains two substantial turbines with a combined output of 45 MW. This was formerly the control centre for the entire the Breadalbane scheme and retains elements of the former control room inside. There is a curved single-storey office block adjacent to the turbine hall, together with an electrical substation which was refurbished 2023-24 replacing the original transformers dating from the 1950s. The water comes from the Stronuich Reservoir in Glen Lyon, 4½ miles (7 km) to the north northwest having previously been used for generation by Lubreoch Power Station and Cashlie Power Station. This provides a head of some 180m (590 feet), the water having travelled through a system of tunnels and pipelines that extends to more than 5½ miles (9 km). The average annual output is 175 million kW/hours.
The station includes a fish pass below the tailrace which features an additional 54 kW turbine.
There is an another small power station located 200m (650 feet) to the west at the bottom of the Falls of Lochay that contributes a further 2 MW of power and which became operational in 1959. This includes a Borland Fish Lift that allows salmon to bypass the Falls, which were previously a barrier, while moving upstream to spawn.
