SPIC Brasil will invest $1.4 billion Brazilian reais ($274.5 million) to expand the Sao Simao hydroelectric plant with a new 310-megawatt generating unit under a contract with Chinese engineering firms, the company said in a Thursday statement.
SPIC Brasil, a unit of the State Power Investment Corporation of China, signed a supply contract with a consortium comprising Dongfang Electric International, DEC Brazil and CGGC Brazil.
Dongfang Electric International will handle engineering, technical supervision and the generator and Francis turbine supply, while CGGC Brazil will oversee installation of the new unit.
The expansion forms part of a planned investment to install the seventh generating unit at the plant on the Minas Gerais-Goias border. The contract value was not disclosed.
UG7 should enter commercial operation in 2030, lifting Sao Simao's installed capacity above 2 gigawatts.
The project follows SPIC Brasil's win in the 2026 Reserved Capacity Auction in March.
"Optimizing existing assets such as the Sao Simao Hydropower Plant is the most efficient and sustainable way to increase the country's renewable and reliable energy capacity," said Adriana Waltrick, CEO of SPIC Brazil.
