Guri

The Guri power plant, which is owned by C.V.G. Electrificacion del Caroni C.A. (EDELCA), opened in 1978 on the Caroni River in Bolivar State, Venezuela, with the activation of the first powerhouse with ten generating units. In 1985, a second powerhouse with ten additional units was completed.

The Guri plant, with a capacity of 10.23 GW, is essential to Venezuela's energy sector, supplying around 80% of the country's electricity. The plant's life was extended by 30 years thanks to a modernization program. It aimed to improve the project's control, protection, and instrumentation systems. The Venezuelan government and the World Bank jointly funded Guri, commonly known as the Simon Bolivar Hydroelectric Plant. The concrete gravity and embankment dam is 7.42 kilometers long and 162 meters tall, with a reservoir of around 4,600 km2. Droughts have impacted power output in the country on various occasions over the years.
