One of the most important plants of the Paranapanema river, Chavantes HPP is located on the São Paulo and Paraná states border, between the cities of Chavantes (SP) and Ribeirão Claro (PR).
In operation since 1970, Chavantes HPP is fundamental in the electric power supply to the National Interconnected System and for the balance of the Paranapanema river basin. The dam stores up to 8.8 billion m³ of water and regulates much of the average flow of the river, which contributes to control the floods.
