The Simplício Hydroelectric Complex is located on the Paraíba do Sul river on the border of Rio de Janeiro and Minas Gerais states in Brazil.
Supported by the Anta Dam, it transfers water through a 26 kilometres (16 mi) circuit to a downstream power plant.
[2][3] Construction on the complex began in January 2007 after the Brazilian Institute of Environment and Renewable Natural Resources (IBAMA) issued an installation permit.
[8] Water from the reservoir then moves into the 73-metre (240 ft) long channel C6 which feeds the project's longest tunnel, T3, at 6.03 kilometres (3.75 mi) in length.
After the reservoir, the water is transferred to intake channel C8 and from there into three 300-metre (980 ft) long penstocks which feed the Simplício Power Plant's three Francis turbines.
