Field Visit (2010)
Lednock power station is a small turbine hall with a single 4MW turbine. It generates power using water carried via tunnel and pressure pipe-way (with surge tower located to the NW of the station) from Loch Breachlaich (see separate item). The tailrace discharges into Loch Lednok which is contained by the Lednok Dam and forms storage for St. Fillans Power Station (see separate items). Lednok power station is a relatively standard example of a small scale power station forming a component of a larger scheme. Some additional interest is gained from the design of the exterior with round arched window surrounds and the use of red sandstone with ashlar dressings for the construction of the station.

Note (25 October 2023)
The Breadalbane hydroelectric scheme
Construction took place between 1951 and 1961 in two sections north and south of Loch Tay respectively. Dams were built at the east ends of Loch an Daimh, Loch Lyon, Loch na Lairige and Stronuich Reservoir, supplying Cashlie, Lubreoch, Finlarig and Lochay power stations respectively in the northern section. Water collection is by a considerable group of aqueducts and tunnels in the area of the River Lyon and the River Lochay and their tributaries. Finlarig power station is noted for operation at a head of 1348 feet, the highest of any of the schemes. It produces 30MW from a Pelton turbine-driven alternator, the larges of its type in Britain.
The southern section has dams on Loch Breaclaich and Loch Lednock. These Lochs are interconnected by a tunnel, with a power station at the entry to Loch Lednock. The latter discharges via a tunnel to St Fillans power station at the east end of Loch Earn, which in turn supplies Dalchonzie power station, which outflows into the River Earn. Aqueducts and further channels collect water from the surrounding area. The total output from this hydroelectric scheme is 120MW.
