Brazil's 334MW Simplício hydro complex is 72.3% complete and is set to be concluded on time for inauguration in late August, a spokesperson for the Brazilian state-run power company Eletrobras Furnas told BNamericas.
The 2.2bn-real (US$1.3bn) complex is being developed and will be operated by Eletrobras Furnas alone.
Simplício is located in the southeastern state of Minas Gerais.
"A new sewerage system is being built in the area for the communities in the region of Paraíba river, as well as a water treatment unit," the spokesperson added.
Last year, Brazilian federal development bank BNDES granted Furnas a 1bn-real loan for the project.
The Simplício hydro complex is part of the federal government infrastructure program, dubbed PAC.
