Zambia has stepped confidently into a new era of energy security and sustainability with the commissioning of the 100 megawatt (MW) Chisamba Solar Power Plant.
Unveiled in late June by President Hakainde Hichilema, this landmark facility is now the country’s largest grid‑connected solar plant and a symbol of its determination to diversify energy sources, protect industries from climate risks, and uplift communities through clean development.
From Hydropower Dependence to Diversification
For decades, Zambia’s energy supply was dominated by hydropower. Iconic installations like the Kariba Dam and Kafue Gorge Power Station powered cities and industries.
But this dependence came at a cost. Prolonged droughts in 2015 and 2019 led to load-shedding of up to 15 hours a day, forcing factories to idle, schools to cut evening classes, and mines to scale down output.
Recognizing the need for resilience, policymakers embraced solar as a complementary source. Chisamba, located in Central Province with abundant sunlight and proximity to transmission lines, was chosen as the site for Zambia’s first truly utility-scale solar facility. By harnessing solar, the nation can now buffer itself against erratic rainfall and stabilize power for critical sectors such as mining, agriculture, and manufacturing.
Policy Foundations and Regulatory Reforms
Chisamba’s success rests on forward-looking policy frameworks. In recent years, Zambia implemented the Renewable Energy Feed-in Tariff (REFiT) Policy, offering predictable tariffs and streamlined licensing.
The Ministry of Energy simplified regulatory procedures and introduced tax incentives for renewable energy equipment, attracting investors who once saw African energy markets as high-risk.
These reforms align with Vision 2030 and the African Union Agenda 2063, both of which emphasize energy access and sustainability. Zambia’s consistent policy direction gave financiers confidence that their investments would be protected over the project’s lifespan.
Financing and Investor Confidence
The Chisamba project is a showcase of blended finance. Zambia’s ZESCO and Kariba North Bank Extension Power Corporation provided seed equity. A US $100 million syndicated loan was led by Stanbic Bank Zambia, with risk guarantees from regional development institutions.
Construction was executed by PowerChina, ensuring international standards and knowledge transfer to local teams. Global investors have praised Chisamba as evidence that Africa’s renewable energy sector is both viable and bankable, paving the way for similar projects across the continent.
Technology and Engineering
Spanning over 250 hectares, the plant features more than 250,000 photovoltaic panels equipped with anti-soiling coatings. Single-axis tracking systems follow the sun’s movement, boosting daily output by up to 18%. A 33/132 kV step-up substation transmits power directly to the national grid, and a SCADA-based control system provides real-time monitoring, predictive maintenance, and efficiency optimization. Future phases include battery energy storage systems (BESS) to store surplus daytime generation and release it during evening peaks, further improving grid stability.
Jobs, Training, and Community Impact
Construction created over 1,300 jobs, with 98% filled by local workers. Training programs certified technicians in PV installation, electrical systems, and safety standards, creating a pipeline of skilled professionals for Zambia’s growing renewable sector.
The project’s social initiatives include clean water boreholes serving nearby villages. There are plans to convert temporary housing into a technical training center and health clinic, and partnerships with schools are introducing STEM-focused energy education for students.
Regional Integration and Export Potential
Zambia’s integration into the Southern African Power Pool (SAPP) allows Chisamba’s surplus power to be exported to neighboring countries like Zimbabwe and Malawi.
This strengthens regional energy security and opens opportunities for Zambia to play a leading role in a future Southern African Green Corridor, where solar and hydro resources are shared across borders.
Environmental Stewardship
By replacing fossil-fuel generation, Chisamba prevents an estimated 150,000 metric tons of CO₂ emissions annually, contributing directly to Zambia’s commitments under the Paris Agreement.
Wildlife corridors were integrated into the site layout. Vegetation management reduces erosion and dust. Water-efficient panel cleaning systems are used, ensuring sustainability. These measures demonstrate that large-scale infrastructure can be climate-conscious and ecologically responsible.
Transforming Mining and Industrial Growth
The mining industry, which contributes over 70% of Zambia’s export earnings, has long been hampered by energy insecurity. Chisamba delivers reliable power to operations like First Quantum Minerals, reducing dependence on costly diesel generators and enabling consistent production.
This stability positions Zambia to market its copper as “green copper,” appealing to global buyers seeking low-carbon supply chains. Beyond mining, reliable power supports value-added processing and manufacturing, keeping more of the mineral wealth in-country.
Economic Ripple Effects
Stable electricity is fueling a wave of new opportunities. Agro-processing hubs are emerging, with cold storage reducing post-harvest losses. SMEs such as welders, bakers, and fabricators are scaling up production without fear of blackouts. Digital services benefit from uninterrupted power, enabling growth in call centers and IT outsourcing. These ripple effects translate into broader economic growth, job creation, and improved living standards across Zambia.
Innovation and Future Projects
Chisamba also serves as a testbed for innovations. Bifacial panels in pilot arrays capture sunlight on both sides. AI-driven predictive maintenance reduces operational costs and downtime.
Feasibility studies are underway for green hydrogen production, using surplus solar energy to create clean fuels for export. Planned future plants in Lusaka and Southern Province will incorporate large-scale battery storage and hybrid solar-wind designs, pushing Zambia further into the forefront of Africa’s clean energy revolution.
Lessons for Africa
Chisamba is already attracting attention from neighboring countries and international agencies. Delegations from Malawi, Botswana, and Kenya have toured the facility, eager to learn from Zambia’s public-private partnership model, community engagement strategies, and policy frameworks.
Development finance institutions cite Chisamba as proof that with clear regulations and stakeholder cooperation, utility-scale renewable energy projects are achievable and sustainable in sub-Saharan Africa.
A Brighter, Greener Future
The Chisamba Solar Power Plant is more than just rows of panels glinting in the African sun it is a testament to Zambia’s ability to transform challenges into opportunities. It is a blueprint for how a nation can harness its natural resources responsibly, empower its people through jobs and education, and lead a region toward a sustainable energy future.
As more projects like Chisamba come online, Zambia’s story will shift from one of energy insecurity to one of resilience, innovation, and leadership in Africa’s clean energy revolution. The sun over Chisamba is not only generating power it is generating hope.
