Countries With The Most Hydro-Electric Capacity
6:48 AM
The ranking of hydro-electric capacity is either by actual annual energy production or by installed capacity power rating. A hydro-electric power plant rarely operates at its full power rating over a full year; the ratio between annual average power and installed capacity rating is the capacity factor. The installed capacity is the sum of all generator nameplate power ratings. Sources came from BP Statistical Review - Full Report 2009.
The top six dams, in descending order of their annual electricity generation, are: the Three Gorges Dam in China, the Itaipu Dam on the border of Paraguay and Brazil, the Guri Dam in Venezuela, the Tucurui dam in Brazil, the Sayano-Shushenskaya Dam in Russia and the Krasnoyarsk hydroelectric dam, also in Russia.
Brazil, Canada, Norway, Switzerland and Venezuela are the only countries in the world where the majority of the internal electric energy production is from hydroelectric power, while Paraguay not only produces 100% its electricity from hydroelectric dams, but exports 90% of its production to Brazil and to Argentina. Norway produces 98–99% of its electricity from hydroelectric sources.
