Overhaul and modernization of the Sobradinho powerplant goes ahead in Brazil

After more than 40 years of operation, the 1050 MW Sobradinho hydropower plant on the São Fran­cisco river, Bahia state, in northeastern Brazil, is to undergo a full technological upgrade.

A contract has been awarded by Companhia Hidrelétrica do São Francisco to Andritz Hydro, for the complete modernization and digitalization of the powerplant.

The scope of supply covers new electro-mechanical equipment, in­cluding: medium and low voltage cubicles; automation and control systems for the powerhouse, spillway and water intake; a condition monitoring system; HIPASE technology for synchronization, excitation, turbine governor and protection; repair services for step-up and station service transformers; cooling and ventilation systems; intake gates; and, as an option, overhaul of the six vertical Kaplan turbines. The contract also includes engineering (basic and detailed de­sign), overall project management, supply of equipment and installation materials, as well as field installation services and training.

The order value is more than €40 million, and the project is expected to be completed in 2025.

Founded in 1948, CHESF is a subsidiary of Eletrobrás and one of the largest power generation and transmission utilities in Brazil, with a total installed capacity of 10 670 MW. Installation of advanced digital automation and control equipment by Andritz will extend the lifetime of the Sobradinho plant, and ensure safe and reliable operations in the future.
