The power house is 1,600 feet (490 m) underground and measures 708 ft (216 m) long, 108 feet (33 m) wide, and 169 feet (52 m) high. It contains 6 x 470 MW pump generators for a total capacity of 2,820 MW with an effective hydraulic head of 653 metres (2,142 ft) and maximum discharge of 510 cubic metres per second (18,000 cu ft/s). The first ...
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 ...
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.
The dam and dykes hold a reservoir covering an area of 2,835 square kilometres (1,095 sq mi) with a useful capacity of 19.365 billion m³. [7] The generating station itself is located 137.2 meters (450 ft) underground, 6 kilometers (3.7 mi) downstream from the main dam. It hosts 16 Francis turbines, set up in two groups of eight each.
A pico hydro system made by the Sustainable Vision project from Baylor University [1]. Pico hydro is a term used for hydroelectric power generation of under 5 kW. These generators have proven to be useful in small, remote communities that require only a small amount of electricity – for example, to power one or two fluorescent light bulbs and a TV or radio in 50 or so homes.
