The state company of Mozambique reported in a statement that energy production increased by 13%, reaching revenue of 226 million euros by June of this year.
Operational Results and Targets
The company noted that 6,399.03 Gigawatt-hours (GWh) were produced between January and June. This figure demonstrates a 13% increase compared to the first half of 2025 and exceeds the set production target by approximately 10%.
Reservoir Recovery Strategy
HCB explains the achievement of these results due to a 'strategy of operation and work based on careful water resource management.' This strategy allowed for 'coordinating increased energy production with the restoration of the Cachora Bassa reservoir reserves, strengthening operational resilience and energy security.'
The Cachora Bassa reservoir is the fourth largest in Africa. Its maximum length is 270 kilometers, the width between banks is 30 kilometers, and its area covers 2,700 square kilometers with an average depth of 26 meters. It supplies electricity to neighboring countries and is one of the largest electricity producers in Southern Africa, employing nearly 800 staff.
Reasons for Improved Hydrological Situation
The company attributes the reservoir recovery to 'more favorable hydrological conditions observed in the Zambezi basin, especially in the Cachora Bassa basin itself,' as well as 'operational management, engineering support, and maintenance measures implemented by the company.'
In the first six months of the year, the useful reserve of the reservoir increased by approximately 35 percentage points. It rose from approximately 20%, previously considered a historical minimum, to a maximum of 56%, corresponding to a level of 316.22 meters. According to HCB, this recovery marks a significant shift after two consecutive hydrological years marked by severe drought, creating conditions for the gradual lifting of operational restrictions that had been in place since July 2024.
Financial Performance and Safety
Financial results aligned with operational indicators: total revenue amounted to 263 million dollars (226 million euros), and net profit exceeded 115 million dollars (99 million euros). HCB also emphasized that these achievements were made under conditions of 'zero workplace accidents' for the reporting half-year.
Management Comments
Thomas Matola, Chairman of HCB's Board of Directors, stated in a declaration that these results demonstrate the company's ability to handle operational difficulties while maintaining water resource sustainability. Matola added that producing more energy while simultaneously restoring strategic reservoir reserves shows HCB's capacity to guarantee reliable power supply.
Context of Mozambique's Energy Sector
It was previously reported that electricity production in Mozambique fell by 25% in 2025 due to water shortages in the HCB reservoir, which occurred after the 'worst rainfall levels' in 43 years, according to official information previously published by Lusa.
According to the 2025 budget execution report, the country's total electricity generation reached 14,408,381 Megawatt-hours (MWh)—or 14,408.3 GWh. This corresponds to 76.7% of the plan fulfillment and a decrease of 25.4% compared to 2024. The country is the largest hydroelectric power producer in Southern Africa, and almost all its output comes from HCB, supplemented by other small dams managed by Eletricidade de Moçambique.
