Inside the Robert-Bourassa generating station, in northern Quebec, the world's largest underground power station, with an installed capacity of 5,616 MW.. An underground power station is a type of hydroelectric power station constructed by excavating the major components (e.g. machine hall, penstocks, and tailrace) from rock, rather than the more common surface-based construction methods.
The power house originally had 11 Pelton turbines made by Escher Wyss (Zürich). Each turbine was coupled to two 1,000 kW DC generators made by Dick, Kerr & Co., which powered the smelting process. There were also two AC generators for auxiliary power. [6] The annual output of the hydroelectric scheme reached 160 GWh, a load factor of over 80%.
In 1911 several more Westinghouse alternators were added as well as a huge Allis-Chalmers generator 3 times the size of the first. A 1924 flood damaged half the turbines and the amount of generators had to be cut in half, including removal of the largest one. In 1947, a large part of the dam collapsed and had to be replaced.
Low-head pumped seawater storage: Currently at very low TRL levels but in the coming decade these technologies could become part of the energy system. Dynamic tidal power: Another potentially promising type of low-head hydro power is dynamic tidal power, a novel and unapplied method to extract power from tidal movements. Although a dam-like ...
During periods of high electric demand, water flows from reservoir into a tunnel drilled through the center of the mountain, driving electric generators in the underground powerhouse. [7] During periods of low demand and excess generation, the generators run in reverse and pump water from Nickajack Lake back up to the top of the mountain, where ...
Dartmouth Dam: Victoria Australia: The 180MW Francis turbine-generator running at full speed was instantaneously stopped by a foreign body left in the penstock following maintenance.[7] The installation shifted about 2m within the base of the 180m high earth and rock fill gravity dam wall of the 3,906GL reservoir.
A second powerhouse was constructed below the original facility in 1897 to house an additional 750-kilowatt AC generator to meet the growing residential and public transit electricity demands of Sacramento. This generator was separated from the turbine turning it by about a 20 feet (6.1 m) rope belt pulley system.
The 1,065 megawatts (1,428,000 hp) power plant is owned by Duke Energy and its last generator was commissioned in 1991. The power station generates electricity by shifting water between an upper and lower reservoir. The upper Bad Creek Reservoir was created by damming Bad Creek and West Bad Creek while Lake Jocassee serves as the lower reservoir.
