Lester Allan Pelton (September 5, 1829 – March 14, 1908) was an American inventor who contributed significantly to the development of hydroelectricity and hydropower in the American Old West as well as world-wide. In the late 1870s, he invented the Pelton water wheel, at that time the most efficient design of the impulse water turbine.
The Hoover Dam in Arizona and Nevada was the first hydroelectric power station in the United States to have a capacity of at least 1,000 MW upon completion in 1936. Since then numerous other hydroelectric power stations have surpassed the 1,000 MW threshold, most often through the expansion of existing hydroelectric facilities.
The dam and reservoir also provide flood control, recreational boating and fishing. The official name of the dam is the Samuel C. Moore Dam, after a former president of the now defunct New England Power Company that originally built it. The dam, reservoir and power station are now owned and operated by Great River Hydro, LLC.
The amount of hydroelectric power generated is strongly affected by changes in precipitation and surface runoff. [4] Hydroelectric stations exist in at least 34 US states. The largest concentration of hydroelectric generation in the US is in the Columbia River basin, which in 2012 was the source of 44% of the nation's hydroelectricity. [5]
The water for the original Folsom hydroelectric plant was obtained from a diversion dam, 650 feet (200 m) long, 24 feet (7.3 m) wide at the top; 87 feet (27 m) wide at the bottom and 89 feet (27 m) tall, across the American River built in the 1890s. The dam diverted a large stream of water into a 2.5 miles (4.0 km) long diversion canal—the ...
With people concerned over the $165 million price tag for the project, it was decided that the dam would control floods, provide irrigation water and produce and sell hydroelectric power to ...
[1] [6] Upon learning about Edison’s advances in electric light technology and electric generators, Rogers worked to bring together a group of investors to create one of the first hydro-electric central stations in the world. [1] For this reason, the Appleton Edison Electric Light Company was formed and incorporated on May 25, 1882. [6]
John Samuel Eastwood (1857, in Minnesota – 1924, in California) was an American engineer who built the world's first reinforced concrete multiple-arch dam on bedrock foundation at Hume Lake, California, in 1908, and was one of California's pioneers of hydroelectric power production.
