It also supervises ZETDC, which delivers electricity through high-voltage transmission lines and regional distribution networks. ZESA Holdings coordinates national energy policies, financing, and investments, whereas ZETDC focuses on the technical and operational aspects of electricity delivery.

Corporate Structure and Ownership of ZETDC

Despite its formal classification as a private limited company, ZETDC remains under government control. It operates as a wholly state-owned entity, managed as a subsidiary of ZESA Holdings. Its registration as a private company pertains to its legal designation rather than its ownership status. Zimbabwe’s government exercises control over ZETDC through direct oversight.

Recent restructuring efforts led to changes in ownership arrangements. The government transferred ZESA Holdings and some of its subsidiaries to the Mutapa Investment Fund. However, ZETDC remained directly under state control, ensuring its continued function as Zimbabwe’s national electricity distributor. This move signified a shift in how the government manages state-owned enterprises, reinforcing the role of ZETDC within the country’s power sector.

ZETDC does not function as a private entity in the conventional sense. Government authorities appoint its leadership and set its policies, ensuring that electricity transmission and distribution align with national objectives. This structure enables continued investment in the country’s electrical infrastructure and aligns ZETDC’s operations with national energy goals.

Ownership and Role of ZESA Holdings

ZESA Holdings operates as a state enterprise fully owned by the Zimbabwean government. As the overarching organization managing the country’s power sector, it directs its subsidiaries in power generation, transmission, and distribution. Its ownership structure underwent modifications when the government placed it under the Mutapa Investment Fund. This move aimed to streamline governance and enhance operational efficiency.

ZESA Holdings functions as the primary utility responsible for ensuring electricity availability across Zimbabwe. It engages in regional electricity trade, maintains power stations, and develops policies that shape the national energy landscape. The government retains full control over ZESA Holdings, making decisions on tariffs, expansion projects, and electricity supply agreements with neighboring countries.

Through its subsidiaries, ZESA Holdings manages Zimbabwe’s key power generation plants. It also works on infrastructure expansion and maintenance to support growing energy demands. Its governance structure includes state-appointed officials who oversee strategic planning and financial decisions.

Power Generation and Electricity Sources in Zimbabwe

Zimbabwe relies on domestic power generation and regional electricity imports. The Kariba South Hydroelectric Power Station and Hwange Thermal Power Station serve as the country’s primary electricity sources. The energy sector also includes smaller coal-fired plants, independent power producers, and renewable energy projects.

Kariba South Hydroelectric Power Station, located at Kariba Dam on the Zambezi River, provides a significant portion of Zimbabwe’s electricity. This hydroelectric facility has an installed capacity of 1,050 megawatts. Seasonal variations in water levels affect its production, as droughts and restricted water allocations can limit electricity generation.

Hwange Thermal Power Station remains the largest coal-fired power plant in Zimbabwe. Following expansion efforts, its installed capacity recently increased from 920 megawatts to 1,520 megawatts. Aging infrastructure and maintenance challenges frequently reduce its actual output. Smaller coal-fired stations in Bulawayo, Harare, and Munyati contribute marginally to the national grid. These facilities require refurbishment and modernization to enhance their reliability.

Independent power producers contribute additional electricity, particularly through renewable energy projects. Some sugar estates generate power from bagasse, a byproduct of sugar production. Triangle Ltd and Hippo Valley Estates produce electricity from sugarcane waste, with surplus energy supplied to the national grid. Emerging solar projects also supplement Zimbabwe’s electricity supply, although their contribution remains relatively small.

Zimbabwe imports electricity from neighboring countries to address supply shortages. The Southern African Power Pool facilitates regional energy trade, allowing Zimbabwe to receive electricity from South Africa, Mozambique, and Zambia. Eskom in South Africa, Hidroeléctrica de Cahora Bassa in Mozambique, and ZESCO in Zambia supply electricity to Zimbabwe under various agreements. These imports play a vital role in stabilizing the national grid during periods of low domestic generation.

Challenges in Zimbabwe’s Electricity Supply

Zimbabwe’s electricity sector faces persistent difficulties related to aging infrastructure, maintenance backlogs, and inconsistent fuel supply. Hwange Thermal Power Station frequently experiences breakdowns due to aging equipment. Coal shortages and mechanical failures further reduce its efficiency. Small thermal plants require rehabilitation to operate at full capacity.

Water levels at Kariba Dam significantly influence Zimbabwe’s hydroelectric generation. Periods of drought limit the amount of water available for power generation, reducing output from Kariba South Power Station. When reservoir levels drop, electricity production declines, resulting in nationwide power shortages. Climate variability continues to affect Zimbabwe’s hydroelectric power capacity.

Tariff structures present another difficulty. ZESA Holdings and ZETDC require adequate revenue to maintain infrastructure and invest in new projects. Historically, electricity tariffs have been set below cost-recovery levels, leading to financial constraints. The inability to secure foreign currency for spare parts and equipment further hampers maintenance efforts.

Zimbabwe’s reliance on electricity imports introduces additional concerns. The country must secure consistent supply agreements and ensure timely payments to regional suppliers. Failure to meet financial obligations has led to disruptions in electricity imports. Limited access to foreign currency complicates efforts to maintain consistent electricity purchases from neighboring countries.

Load shedding continues to affect industries, businesses, and households. Power outages reduce productivity and disrupt essential services. Zimbabwe requires increased investment in power generation capacity and transmission infrastructure to meet growing electricity demands.

Renewable Energy and Expansion Efforts

Zimbabwe seeks to expand its renewable energy capacity through independent power producers and government-led initiatives. Solar energy presents opportunities for diversifying the energy mix. Several solar projects have been licensed, including planned installations in Gwanda and Bulawayo. These projects aim to increase Zimbabwe’s renewable energy contribution to the grid.

Bagasse cogeneration at sugar estates remains an important renewable energy source. Sugar producers generate electricity using sugarcane waste, contributing to national supply. Biomass and mini-hydro projects also play a role in Zimbabwe’s renewable energy strategy.

Efforts to develop additional hydroelectric capacity continue. Zimbabwe and Zambia have explored the Batoka Gorge Hydroelectric Project, a proposed 2,400-megawatt facility. This project remains in the planning stages, requiring financing and regulatory approvals before construction can proceed.

Energy efficiency measures, including demand-side management programs, aim to reduce strain on the national grid. Net-metering initiatives encourage businesses and households to install solar panels and feed excess power back into the grid. These policies seek to stabilize the electricity supply while promoting renewable energy adoption.

Investment in Infrastructure and Energy Security

Zimbabwe requires substantial investment in power generation, transmission, and distribution infrastructure. Upgrading existing facilities and constructing new power plants will improve energy security.
