Jurumirim dam
The Jurumirim Hydroelectric Dam (Armando Avellanal Laydner) is in the state of São Paulo, Brazil, and spans the Paranapanema River. It covers ten municipalities in the south-central area of the state, where its right bank borders the town of Cerqueira César and its left bank borders Piraju, accessed via highway SP-261.
It was owned and operated by Duke Energy until 2017, when it was bought by the Brazilian branch of the Chinese multinational company China Three Gorges Corporation (CTG).[1]
Characteristics
Construtora Servix began construction in 1956 and completed the project in 1962. The name Jurumirim comes from the Tupi language and means "little falls".
The dam can produce 98.000 kW of power, with two Kaplan-type turbines, with a height difference of 30.9 m. Its reservoir inundates an area of about 449 Km2.[2][3]
According to the National Electric System Operator (ONS), the lake at the Jurumirim Hydroelectric Plant is capable of storing 2% of the volume that can be dammed by the reservoirs of the Southeast/Central West System, which represents 34.42% of the water storage of the Paranapanema river.
The river basin has an area of 17,800km². It is about 100 km long and in some stretches exceeds three km in width. The dam has an area of 449 km², containing a volume of water almost four times greater than that of Guanabara Bay in Rio de Janeiro, with a discharge of 1,790 m³/s.449 km².
The generation of electrical energy is the primary purpose of hte dam, but it also serves to accumulate water to provide to other plants on the Paranapanema, including, in the direction of the Paraná River: Chavantes, Salto Grande, Canoas II, Canoas I, Capivara, Taquaruçu e Rosana. All of these plants are managed by CTG Brasil.
