Cruachan - The Hollow Mountain - Power Station - Lochawe, Argyll & Bute, Scotland

Описание: The Cruachan Power Station (also known as the Cruachan Dam) is a pumped-storage hydroelectric power station in Argyll and Bute, Scotland. The scheme can provide 440 MW of power and produced 705 GWh in 2009.

The turbine hall is located inside Ben Cruachan, and the scheme takes water between Cruachan Reservoir to Loch Awe, a height difference of 396 m (1,299 ft). It is one of only four pumped storage power stations in the United Kingdom, and is capable of providing a black start capability to the National Grid.

Construction began in 1959 to coincide with the Hunterston A nuclear power station in Ayrshire. Cruachan uses cheap off-peak electricity generated at night to pump water to the higher reservoir, which can then be released during the day to provide power as necessary.

The power station is open to visitors, and around 50,000 tourists visit it each year. - https://www.visitcruachan.co.uk/

The power station is on the A85 road, about 8 km (5.0 miles) west of Dalmally, on a branch of Loch Awe leading to the River Awe, which is the outflow from the loch, at its north west corner. There is a seasonally open Falls of Cruachan railway station nearby.

Cruachan was one of the first reversible pumped-storage systems, where the same turbines are used as both pumps and generators. Previous pumped-storage systems used separate pumps with a network of pipes to return water to the upper reservoir, making them much more expensive to build than conventional hydroelectric systems.

In June 2021, Drax applied to build a further 600 MW pumped storage capacity using the same reservoir, to a combined 1 GW for seven hours of storage, approved in July 2023 and possibly operating by 2030.
