ZESCO Board chairperson Vickson Ncube has emphasised Zambia’s commitment to a diversified energy strategy, moving away from sole reliance on hydropower to ensure national energy security and prevent future load shedding.
Speaking on Diamond TV last night, Ncube detailed the country’s proper energy mix, which integrates solar, hydro, and coal power sources.
Ncube stated that depending on a single power source is a shortcut to darkness.
He underscored the necessity of a multi-faceted approach to electricity generation.
Ncube highlighted that the current investment in a blend of energy sources aims to create a resilient system capable of withstanding challenges such as droughts or cloudy conditions.
“We cannot really depend on solar for us to have our energy. That is why we have an energy mix. Not a single source,” Ncube explained.
He elaborated on the concept, noting that solar power plants, such as the recently launched 100-megawatt Chisamba solar plant, will generate electricity during the day, allowing hydropower reserves, primarily from the Kariba Dam, to be conserved.
This stored water will then be utilised at night when solar generation is not possible, effectively acting as a “battery” for the nation’s power supply.
He added that the inclusion of thermal sources, such as the Maamba coal plant, alongside solar, is not a luxury but a crucial step towards maintaining a stable and predictable energy supply
Ncube acknowledged that Zambia’s historical heavy reliance on hydropower from the Kariba Dam has exposed the country to significant risks due to climate change and inconsistent rainfall patterns.
The government has set an ambitious target to add 1,000 megawatts to the national grid by the end of 2025.
Ncube expressed confidence that this goal is achievable and essential for Zambia to achieve energy independence.
