Hidroelectrica de Cahora Bassa (HCB), the company which operates the Cahora Bassa dam, on the Zambezi River in the central Mozambican province of Tete, has launched the second phase of the Centro Sul (RS2) rehabilitation project, intended to overhaul the power station on the south bank of the river.

The project is part of modernization and rehabilitation program for the hydroelectric complex, under the “Vital Capital Expenditure (CAPEX) 10-Year Investment Plan.”

According to the Chairperson of the HCB Board of Directors, Tomás Matola, cited in a statement from the company, the main objective of the project is to improve the effectiveness and efficiency of the equipment responsible for the production and transmission of electricity, ensuring the sustainability, reliability, and competitiveness of the power generation system.

He revealed that, with the implementation of RS2, the company expects to increase the total generation capacity of the power station by 90 megawatts (MW), increasing the capacity of each of the five generators from 415 MW to 433 MW.

“The increase will strengthen the region’s energy supply, supporting economic growth, and extending the plant’s operational lifespan by more than 45 years, mitigating downtime risks and improving the generation system’s performance. RS2 is part of HCB’s ongoing efforts to innovate and strengthen the national energy sector, ensuring that the hydroelectric complex remains operational and structured, even after 50 years of existence”, reads the note.

According to the document, in order to ensure alignment on the scope, goals, and work plan, HCB held a three-day meeting with the project partners – the Andritz Hydro consortium, SIJV technical consultants (Sweco and Intertechne Joint Venture), and Fichtner, companies with extensive experience in hydroelectric power plants.

“The implementation plan calls for the annual rehabilitation of each of the five power generators, including equipment replacement and subsequent commissioning. To bridge the temporary production deficit, HCB is prioritizing two new strategic projects: the Cahora Bassa North Power station, with an installed capacity of 1,245 MW (three groups of 415 MW each), and the Solar Photovoltaic Power Plant, estimated at 400 MWac, both in Tete Province”, reads the note.

This infrastructure, the document says, will enhance renewable energy production, reducing water dependence and promoting sustainability, consolidating HCB’s position as one of the largest hydropower producers in Southern Africa.
