Object: hydroelectric exploitation.
Participation: execution, under EPC (Engineering, Procurement and Construction) regime, of all the civil works of the Foz do Estrela PCH, including earthworks, execution of deviation and adduction tunnels, concrete works and finishing of the exploitation.
The Ministry of Mines and Energy considered as a priority project the Small Hydroelectric Power Plant Foz do Estrela. Authored by Brookfield Renewable Energy, through São Luiz Energética, lo-cated in Paraná, it has 29.5 MW of installed capacity and two generating units.
The PCH Foz do Estrela will be located on Iratim River, in the municipality of Coronel Domingos Soares, PR. The total installed power will be 29.5 MW. The dam will be made of conventional concrete (CCV) and roller compacted concrete (CCR), and will have an extension of approximately 223 m, including the free-flowing weir spillway and the dam on the left bank, with the spillway at an elevation of 675.0 m and the dam at an elevation of 680 m. The dam on the right bank will be on land and rockfill, and will have an extension of ~ 75 m. The deviation will be made by a deviation tunnel, with an extension of 180 m and a section of 8 x 8 m.
The generation hydraulic circuit is composed of gravity type water intake and an adduction tunnel with an extension of 1,125 m and a section of 6 x 6 m. The powerhouse will be sheltered type, and the generation will be obtained by two Francis turbines with horizontal axis of 14.75 MW each.
