Zimbabwe is not short of possible energy sources. It has major coal deposits, the Kariba South hydropower station, strong solar conditions, biomass resources and a central position in Southern Africa’s electricity network. Its main problem is turning those resources into dependable and affordable energy.
The difference between installed capacity and electricity that can actually be delivered explains much of Zimbabwe’s energy story. Drought limits hydropower generation, older coal units suffer breakdowns, transmission infrastructure needs investment and electricity imports depend on the conditions facing neighboring countries. At the same time, mines, farms, factories and households are demanding more power.
Zimbabwe’s energy future therefore depends on more than building power stations. It also requires stronger transmission lines, financially stable utilities, private investment, off-grid systems and a more balanced mix of coal, hydroelectricity, solar power and other technologies.
Zimbabwe Has Power Capacity, but Not Enough Dependable Supply
Zimbabwe’s electricity system is built mainly around two large facilities: Kariba South Power Station on the Zambezi River and Hwange Power Station in the country’s west. Smaller thermal stations, independent renewable projects and imported electricity complete the national supply.
The government’s 2025 National Energy Compact placed Zimbabwe Power Company’s installed capacity at 2,640 megawatts. This included 1,050 MW at Kariba South, 920 MW from Hwange units 1–6 and 670 MW from the newer Hwange units 7 and 8. When independent and off-grid generation is included, national installed capacity was estimated at 2,962 MW.
Those numbers suggest that Zimbabwe should be able to cover peak demand of about 2,000 MW. In practice, dependable capacity was estimated at only 1,200–1,600 MW. Water shortages, maintenance requirements, equipment failures and fuel constraints prevent the country from using all its nominal capacity at the same time. Load shedding and electricity imports remain necessary even though installed capacity appears sufficient on paper.
This gap affects the wider economy. A World Bank assessment estimated that electricity shortages cost Zimbabwe the equivalent of 6.1% of gross domestic product each year through inefficient generation, network losses and the economic effects of unreliable supply. Mining, irrigation, food processing, tourism and manufacturing are especially sensitive to long outages.
Hwange Keeps Coal at the Center of Zimbabwe’s Energy System
Coal remains Zimbabwe’s largest source of installed electricity capacity. The country has substantial coal resources, particularly around Hwange in Matabeleland North, where mining and power generation have been closely connected for decades.
Hwange Power Station is the center of the coal sector. Its older six generating units provide 920 MW of installed capacity, although age and maintenance problems often reduce their output. Units 7 and 8 added 670 MW and entered service in 2023, giving Zimbabwe an important source of newer baseload generation at a time when drought was reducing output from Kariba.
The Hwange expansion strengthened the power system, but it did not remove the basic weaknesses of coal generation. Older units still require rehabilitation, while coal must be mined, processed and delivered consistently. Cooling water, spare parts, foreign currency and technical maintenance also affect availability. Zimbabwe’s smaller thermal stations in Harare, Bulawayo and Munyati are old and are frequently unavailable. Government energy planning documents describe these stations as being affected by aging equipment and related operational problems.
Coal therefore has two different roles in Zimbabwe. Newer capacity at Hwange provides a more reliable base when rainfall is poor, while older coal infrastructure is itself a source of uncertainty. This creates a difficult policy choice. Zimbabwe needs dependable electricity for mines and industry, but additional coal projects require large investments and could lock the country into high-emission infrastructure for decades.
Coal also has economic importance beyond electricity. The Hwange region depends on mining, transport and power-sector employment. Any future reduction in coal use would need to consider local jobs and regional development, not only national emissions targets.
Kariba Hydropower Is Powerful but Exposed to Drought
Kariba South is Zimbabwe’s largest hydropower station and one of its most important pieces of national infrastructure. Its eight units have a combined installed capacity of 1,050 MW. The station shares Lake Kariba and the wider dam system with Zambia, which operates Kariba North Bank on the opposite side of the Zambezi River.
Hydropower gives Zimbabwe electricity without the regular fuel costs of a coal or oil plant. It can also adjust output relatively quickly, making it useful for responding to changes in demand. However, generation is limited by the amount of water that the Zambezi River Authority permits Zimbabwe and Zambia to use.
Recurring drought has exposed this dependence. When inflows into Lake Kariba fall, available water must be carefully divided between the two countries and preserved for future seasons. Zimbabwe may therefore have 1,050 MW of hydroelectric equipment installed but be allowed to generate only a fraction of that capacity. A 2025 government energy-security presentation reported Kariba generation at around 500 MW despite its much higher installed capacity.
Climate variability makes this more than a temporary operating problem. A system that depends heavily on one reservoir will remain vulnerable even after turbines and transmission equipment are upgraded. Zimbabwe needs Kariba, but it cannot assume that Kariba will always deliver its full output.
The proposed Batoka Gorge Hydroelectric Scheme, planned with Zambia downstream from Victoria Falls, could add major regional capacity. Zimbabwe’s Energy Compact calls for updated feasibility work, developer procurement and eventual construction, but its own schedule places a possible construction start near the end of the decade. Batoka is therefore a long-term option rather than an immediate answer to power shortages.
The Electricity Grid Is Both a National Asset and a Bottleneck
Zimbabwe occupies a strategically important position in the Southern African Power Pool. Its transmission system forms part of the central corridor linking electricity networks across the region. In theory, this location allows Zimbabwe to import power during shortages, export future surpluses and carry electricity between neighboring markets.
In practice, aging equipment and limited transmission capacity restrict those opportunities. The National Energy Compact states that transmission and distribution assets require replacement, rehabilitation and expansion. It also reports that inadequate transmission infrastructure prevents a large share of possible Southern African Power Pool trading from taking place.
Zimbabwe imports electricity mainly from South Africa and Mozambique, with some regional supply also available through Zambia. The Energy Compact identifies approximately 300 MW from South Africa’s Eskom and 50 MW from Mozambique’s Cahora Bassa system as important sources of additional supply. These arrangements are valuable, but they are not guaranteed. Neighboring utilities face their own droughts, plant failures and domestic demand, while Zimbabwe’s ability to pay for imports can also affect supply.
Distribution infrastructure creates another problem. Businesses and communities may be near power lines but still lack an affordable connection. As of May 2025, the national utility reported a backlog of 467,470 customer connections. High connection costs mean that some households remain unconnected even where distribution networks already exist.
The 2022 census reported electricity access for 62% of households, including both grid and off-grid sources. Only 33.7% was classified as on-grid access, while 28.3% came from off-grid systems. A later National Electrification Strategy produced a lower overall estimate, showing how definitions and household growth can change the picture. What remains clear is that access is much weaker in many rural areas and that grid expansion alone will not be fast enough to reach every household.
Zimbabwe Imports All of Its Petroleum Fuels
Zimbabwe does not have commercial domestic oil production or an operating refinery capable of meeting national demand. It imports all its petroleum fuel requirements, including petrol, diesel, aviation fuel and liquefied petroleum gas.
The most important petroleum route begins at the Mozambican port of Beira. Fuel is stored there and pumped through the Beira–Feruka pipeline into eastern Zimbabwe before continuing toward storage facilities near Harare. Additional fuel enters by road and rail from Mozambique and South Africa. Government figures identify storage capacity at Beira, Feruka, Msasa, Mabvuku and several smaller locations, making tanks and pipelines central to Zimbabwe’s energy security.
Oil is not a major electricity source, but it remains essential to the economy. Diesel powers freight transport, mining equipment, farm machinery and backup generators. Petrol supports road transport, while aviation fuel matters for tourism and trade. When grid supply is unreliable, businesses often operate diesel generators, increasing both costs and petroleum demand.
Zimbabwe also blends imported petrol with domestically produced ethanol when supplies permit. Government policy allows blends of up to 20% ethanol. This provides a market for the domestic sugar and ethanol industry while reducing part of the country’s imported petrol requirement. However, blending cannot remove Zimbabwe’s wider dependence on foreign oil and international fuel prices.
The petroleum system is therefore an infrastructure and foreign-exchange issue as much as an energy issue. Reliable pipelines and storage reduce the danger of physical shortages, but the country must still obtain foreign currency to purchase fuel.
Natural Gas Remains a Resource Prospect Rather Than a Major Industry
Natural gas plays only a limited role in Zimbabwe’s present energy system. The country imports gas products and does not operate a large domestic conventional gas industry. However, coal-bed methane deposits have attracted interest, especially in the Lupane and Hwange areas.
Coal-bed methane is natural gas found within coal seams. In principle, Zimbabwe could use it for electricity generation, industrial heat, fertilizer production or household fuel. Gas-fired power could also provide flexible generation alongside solar energy and reduce some dependence on aging coal plants.
The difficulty is moving from geological potential to commercial production. Exploration has taken place over many years, but reserve estimates, financing, pipelines and reliable commercial projects remain limited. Zimbabwe’s Energy Compact records the presence of substantial gas indications in western areas while also showing that further exploration and quantification are required.
Natural gas should therefore be described as a possible part of Zimbabwe’s future mix, not as an established pillar of current supply. Its contribution will depend on whether developers can confirm usable reserves, attract capital and connect production to power stations or industrial customers.
Nuclear Power Is an Ambition, Not a Current Energy Source
Zimbabwe does not operate a nuclear power plant, and nuclear energy contributes nothing to its present electricity generation. The government has nevertheless begun discussing whether nuclear technology could support long-term energy security.
In late 2024, officials said Zimbabwe had approached the International Atomic Energy Agency and was considering cooperation with Russian investors. The stated interest focused on small modular reactors rather than a conventional large nuclear plant. Small modular reactors are designed to have lower individual capacity and could, in theory, fit a smaller electricity system more easily than a very large reactor.
The program remains at an exploratory stage. Zimbabwe would need nuclear legislation, an independent safety regulator, trained specialists, emergency planning, waste-management arrangements and a credible financing structure before construction could begin. The national grid would also need to become stronger and more stable.
Nuclear power may remain part of policy discussion because it offers continuous low-carbon electricity and does not depend on rainfall. However, it cannot address Zimbabwe’s immediate shortages. Solar development, grid rehabilitation, maintenance at existing plants and stronger regional trade can be delivered sooner and at smaller financial scale.
Solar Energy Is Moving From Backup Power to National Strategy
Solar power has become the clearest option for diversifying Zimbabwe’s electricity system. The country has strong solar resources, while modular projects can be installed faster than coal, hydroelectric or nuclear plants. Solar can serve the national grid, industrial customers, farms, hospitals, schools and households that are far from transmission lines.
Zimbabwe’s solar market has developed partly because the grid is unreliable. Homes and businesses use rooftop panels, batteries and inverters to maintain lighting, communications, refrigeration and other essential services during outages. Mining companies are also developing private solar plants to reduce production interruptions and dependence on utility supply.
The 2025 National Energy Compact lists a large group of licensed solar projects, including developments connected to platinum, gold and other mining operations. It also reports 28.5 MW of operational net-metered capacity in 2024 and sets a target of 100 MW. Under net metering, customers with their own generation can send surplus electricity to the grid and receive credit.
Zimbabwe’s broader target is to increase renewable capacity from 1,282 MW in 2024 to 2,640 MW by 2030. Because the starting figure includes large hydropower, the more important target is expanding solar, wind, bagasse and other renewables excluding large hydro from 7.8% to 29% of installed capacity.
Solar alone cannot provide continuous power after sunset. Battery storage, flexible generation, regional electricity trading and better demand management will be needed as solar capacity grows. The government has started seeking utility-scale battery projects to help manage variable renewable generation.
Biomass and Clean Cooking Are Central to Zimbabwe’s Real Energy Mix
A profile based only on power stations would miss one of Zimbabwe’s largest energy issues: household cooking. Firewood remains a major fuel, especially in rural areas. According to the 2022 census figures used in government energy planning, 60.7% of Zimbabweans used firewood for cooking, while 38.7% had access to clean cooking technologies.
Heavy dependence on firewood links energy policy to deforestation, household income, health and time use. Collecting fuel takes time that could otherwise support education or paid work, while smoke from indoor cooking affects household health. Electricity shortages and high appliance costs also make it difficult for families to move directly to electric cooking.
Zimbabwe’s clean-cooking strategy includes LPG, ethanol, biogas, improved stoves and electricity. The government aims to raise clean-cooking access to 70% by 2030 and reduce dependence on firewood and charcoal. It estimates that meeting this target will require hundreds of millions of dollars in investment.
Agricultural waste also provides energy opportunities. Sugar estates already use bagasse, the fibrous material left after sugarcane processing, to generate heat and electricity. Biogas can use animal waste or sewage, while small hydro and solar systems can power irrigation, crop drying and grain milling. IRENA has identified solar pumps, dryers, shellers and mills as practical ways to connect renewable energy with Zimbabwe’s agricultural economy.
Mining Growth Is Raising the Cost of Electricity Shortages
Zimbabwe’s mining sector is becoming one of the strongest drivers of electricity demand. Gold, platinum, chrome and lithium projects require reliable power for crushing, processing, ventilation, pumping and mineral refining. New investment in energy-transition minerals creates export opportunities, but it also places additional pressure on a system that already struggles to serve existing demand.
The National Energy Compact identifies platinum, lithium and related minerals as major sources of future load growth. World Bank projections have suggested that national electricity demand could rise from about 1,950 MW in 2022 to more than 5,000 MW by 2030, with mining and agriculture playing leading roles.
This helps explain why mining companies are developing their own solar plants or seeking direct power arrangements. Private generation can protect mines from outages, but it can also create a divided system in which large industrial users secure dedicated supply while households and smaller businesses remain exposed to load shedding.
Agriculture creates a different kind of demand. Irrigation, refrigeration, milling and food processing require energy, but many farms are far from strong grid connections. Decentralized solar and mini-hydro systems may therefore deliver more economic value than waiting for full grid expansion.
Zimbabwe’s Energy Future Depends on Diversification Before Expansion
Zimbabwe needs more electricity, but simply adding nominal capacity will not solve the problem. New plants must be supported by dependable fuel or water, modern transmission lines, affordable customer connections and utilities able to maintain infrastructure and pay independent producers.
Coal will remain important through Hwange because it provides power when Kariba is limited by drought. Hydropower will remain valuable, but future planning must recognize changing rainfall conditions. Imported petroleum will continue to support transport and backup generation, while domestic natural gas and nuclear power remain possible longer-term options rather than immediate sources.
Solar has the strongest potential for rapid growth. It can serve mines, farms, cities and remote communities, but its national value will depend on batteries, transmission investment and fair arrangements for selling power to the grid. Biomass, biogas and clean-cooking technologies will be equally important for households that experience the energy sector mainly through firewood rather than electricity.
Zimbabwe’s defining energy question is whether it can convert its wide range of resources into reliable supply. The country does not need one technology to replace all the others. It needs a system in which coal, hydropower, solar, imports, storage and decentralized energy compensate for each other instead of leaving the economy exposed whenever one source fails.
