ANDRITZ receives major order for rehabilitation of Mozambique’s largest hydropower plant

GRAZ/VIENNA, JULY 16, 2025. Hidroeléctrica de Cahora Bassa (HCB), Mozambique’s leading hydropower generation company, has awarded ANDRITZ a contract for the rehabilitation of the Cahora Bassa hydropower plant. It is the largest hydropower plant in Mozambique and one of the largest in Africa. The order value for ANDRITZ is in the mid three-digit million-euro range. It was included in ANDRITZ’s order intake for the fourth quarter of 2024.

Commissioned in 1975, the 2,075 MW plant on the Zambezi River supplies more than half of Mozambique's electricity and exports significant amounts to neighboring countries. More than an energy asset, Cahora Bassa is a cornerstone of Mozambique's economic and social development. HCB’s rehabilitation project, called REABSUL II, aims to enhance the efficiency, reliability, availability, and maintainability of the plant. The capacity of the turbines will be increased by more than 4% to 433 MW per unit.

ANDRITZ will supply five new state-of-the-art 480 MVA generators, five new Francis turbine runners, control and protection systems, and hydromechanical structures. The scope of the contract includes the design, engineering, manufacturing, and supply of the high-efficiency equipment, as well as installation, testing, and commissioning at the project site.

After three years of preparation work, during which the new equipment will be designed and manufactured and the site infrastructure prepared, Cahora Bassa’s generating units will be replaced one by one, while ensuring the stable and constant operation of the other units. This is a major challenge, especially for the rehabilitation of the common systems, and will also require thorough coordination with the rehabilitation of the Songo Converter Substation, which HCB will carry out in parallel.

ANDRITZ is proud to contribute to this key project for the region and is committed to supporting the hydropower market in Mozambique to ensure renewable energy supply for decades to come.
