The Chippawa-Queenston Power Canal in 1921; it was the first of three sources to provide water to the Generating Stations. Adam Beck II contains 16 generators and first produced power in 1954. The water was first diverted from the Niagara River by two five-mile (8 km) tunnels under the city of Niagara Falls, Ontario, that start above the falls. [4]
The runner of the small water turbine. A water turbine is a rotary machine that converts kinetic energy and potential energy of water into mechanical work. Water turbines were developed in the 19th century and were widely used for industrial power prior to electrical grids. Now, they are mostly used for electric power generation.
Most hydroelectric power comes from the potential energy of dammed water driving a water turbine and generator. The power extracted from the water depends on the volume and on the difference in height between the source and the water's outflow. This height difference is called the head.
The Three Gorges (22,500 MW - 32 × 700 MW and 2 × 50 MW) is operated jointly with the much smaller Gezhouba Dam (2,715 MW). The total generating capacity of this two-dam complex is 25,215 MW. The Itaipu on the Brazil–Paraguay border has 20 generator units with overall 14,000 MW of installed capacity. However, the maximum number of ...
During periods of peak demand water is released to generate power. Electrical generation can begin within two minutes with peak electric output of 1872 MW achieved in under 30 minutes. Maximum water flow is over 33 million US gallons (120,000 m 3) per minute. This process was designed to level the load of nearby nuclear power plants on the grid.

The Lewiston Pump-Generating Plant houses 12 electrically powered pump-generators that can generate a combined 240 MW (320,000 hp) when water in the upper reservoir is At night, two 46 ft (14 m) wide by 66 ft (20 m) tall tunnels [ 10 ] divert a substantial fraction (600,000 US gal (2,300 m 3 ) per second) of the water in the Niagara River 4.5 ...
The dam also has a 13.25 ft (4.04 m) diameter sluice which can be used to allow water to bypass the turbines. [1] Downriver from the dam is a trout breeding hatchery, which is one of the southernmost hatcheries for trout, due to the cool temperature of the water that the dam releases. [5]
