Zambia has started construction on a 100 MW solar power plant in Chirundu, a 35 MW solar facility in Choma, and a 330 kV transmission line in Southern Province, marking a major expansion of the country’s renewable energy capacity. The projects, launched between December 4 and 8, are being developed by state utility Zesco to reduce dependence on hydropower, which currently provides about 90% of Zambia’s electricity supply.
The Chirundu plant, estimated at $90 million, is a joint venture between Zesco and JIGSCO Energy and forms part of the government’s national target to install 1,000 MW of solar capacity. The Choma plant is being developed by China Energy Engineering Group Hunan Electric Power Design Institute, adding further scale to Zambia’s renewable generation portfolio.
The 330 kV transmission line is designed to reinforce power evacuation capacity from Southern Province, where Zambia’s largest hydropower schemes — Kafue Gorge and Kariba North Bank — are located. By integrating these solar projects into the national grid, Zesco aims to limit power shortages during dry seasons and support grid stability amid climate‑driven fluctuations in hydroelectric output.
The projects illustrate Zambia’s shift toward a more balanced energy mix and highlight public‑private cooperation to expand renewable generation while reducing vulnerability to water‑level risk in key hydro reservoirs.
