Since we live on a continent with unreliable electricity grids, private diesel and petrol generators have become essential lifelines for businesses and homes to thrive.
Nigeria stands in a league of its own when it comes to private generator use, but several others follow closely in dependence.
Based on estimated unit numbers, installed capacity, market share, and overall reliance, here are the top 5 African countries with the highest generator usage.

1. Nigeria
The giant of Africa stands above the rest as Africa’s generator capital. According to Brookings in 2019, out of about 6.5 million backup generators across Sub-Saharan Africa, roughly 3 million are in Nigeria alone.
This huge number of generators provides 15–20 GW of capacity, which often surpasses the country’s official grid output. With frequent grid collapses, a population exceeding 200 million, and widespread outages, generators are a necessity for households, businesses and industries.
Nigerians spend trillions of naira annually on fuel and units, with generator power accounting for a huge portion of the country’s electricity needs.
2. South Africa
After Nigeria comes South Africa. Prolonged Eskom (South Africa’s state-owned power utility) load-shedding, which sometimes exceeds 200 days a year in peak periods, has made businesses, mines, data centres, and households invest heavily in backup systems.
While the exact unit counts are lower than Nigeria’s due to a more formal economy and larger average generator sizes, the country leads in revenue share for higher-capacity units. Mining and manufacturing sectors particularly rely on multi-megawatt fleets of generators.
3. Ghana
Ghana experiences about 9–10 outages (called Dumsor) per month in some years. This has pushed businesses and residents toward generators. It features prominently in West Africa’s high-dependence cluster, where backup power can supply a large share of electricity needs.
The industrial and commercial sectors drive demand for mid-to-large units, supported by economic growth in Accra and other hubs.
4. Kenya
Kenya has advanced electricity supply systems like geothermal and hydro, but inconsistent supply and rural gaps make owning generators essential.
The fast-growing economy, especially in the country’s capital, Nairobi, keeps generators in high demand. The tech, telecom infrastructure and commercial buildings are major users, which contributes to strong market presence in East Africa.
5. Democratic Republic of Congo (DRC)
In DRC, according to the World Bank, only 21% of the population has electricity access. Grid supply is highly unreliable, with Kinshasa receiving just 480–500 MW against ~1,000 MW peak demand. This results in daily load-shedding and thousands of monthly outages.
Generators are therefore heavily relied on to keep business running.
Ethiopia, Uganda, Senegal, Côte d’Ivoire, and Tanzania also rank high in outage frequency and generator imports.
This ranking draws from aggregated market analyses and energy studies, so actual numbers fluctuate with economic shifts, fuel prices, and policy changes.
