Andritz is to perform the complete modernization and digitalization of the 1050MW Sobradinho hydropower plant on the São Francisco river, Bahia state, Brazil, after signing a contract valued after over €40 million with Companhia Hidrelétrica do São Francisco (CHESF). 

Under the terms of the deal Andritz will supply new electro-mechanical equipment, including medium and low voltage cubicles, automation and control systems for the powerhouse, spillway and water intake, conditioning 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.

Sobradinho has been in operation for more than 40 years.  Installation of advanced digital automation and control equipment by Andritz will extend the lifetime of the plant and ensure safe and reliable operations in the future.

The project is expected to be completed in 2025.
