The Simón Bolívar Hydroelectric Plant, also Guri Dam (Spanish: Central Hidroeléctrica Simón Bolívar or Represa de Guri), previously known as the Raúl Leoni Hydroelectric Plant, is a concrete gravity and embankment dam in Bolívar State, Venezuela, on the Caroni River, built from 1963 to 1969.[3] It is 7,426 metres long and 162 m high.[4] It impounds the large Guri Reservoir (Embalse de Guri)[5] with a surface area of 4,250 square kilometres (1,641 sq mi).[6]

The Guri Reservoir that supplies the dam is one of the largest on earth. The hydroelectric power station was once the largest worldwide in terms of installed capacity, replacing Grand Coulee HPP, but was surpassed by Brazil and Paraguay's Itaipu.[7]
