In a collaborative effort to address declining electricity generation capacity at Kariba Dam, Zimbabwe and Zambia have launched feasibility studies for the installation of floating solar systems. This initiative, supported by the African Development Bank, aims to harness renewable energy solutions in response to the challenges posed by climate change and recurring droughts that have significantly impacted hydroelectric power production in the region.
Zimbabwe and Zambia, through the Zambezi River Authority (ZRA), have embarked on feasibility studies to explore the installation of floating solar systems at Kariba Dam. This initiative responds to the declining electricity generation capacity at the dam’s hydroelectric plants, which have been significantly affected by recurring droughts linked to climate change.
During a recent address to the National Assembly, Energy and Power Development Minister Edgar Moyo revealed that the study is being conducted with the support of the African Development Bank (AfDB). “We are engaged in a program through the ZRA and the council of ministers, a bi-national body comprising both countries. Our goal is to complete the feasibility study by the first quarter of 2025, which will allow us to begin implementing floating solar systems on Lake Kariba,” Moyo stated. He added that additional initiatives concerning floating solar systems are scheduled to commence early next year.
Floating solar systems present a sustainable solution, enabling energy companies to expand solar power generation without requiring additional land. These solar panels, mounted on floating platforms, promise high energy yields and benefit from the cooling effects of the water beneath, enhancing their efficiency even in hot weather.
Zimbabwe is currently facing challenges with power generation, particularly at key facilities like Kariba Dam and Hwange Thermal Power Station. While Kariba Dam has an installed capacity of 1,050 MW, recent output has plummeted to approximately 184 MW. The ongoing feasibility study, funded by the AfDB, aims to assess the viability of implementing floating solar technology on Lake Kariba, offering a potential pathway to improve energy production in the region.
