The Zambia Riverside Solar Power Station is a 34 megawatts in Zambia. The privately owned solar farm was originally commissioned in April 2018, as a 1 MW power station by (CEC), who own the energy infrastructure. In December 2021, CEC signed an (EPC) contract with to expand the solar farm by 33 extra MW over the next 12 months. CEC transmits and distributes t. Zambia’s projects are adopting cutting-edge tech: Zambia’s Kafue River has a natural 450-meter elevation drop over 60km—essentially nature’s ready-made PSH site. The ongoing Kafue Gorge Lower project (750MW) uses this topography to store energy without needing massive artificial reservoirs. [pdf]
