Electricity: Where Ghana Stands Among African Producers

A recent article by Business Insider Africa, drawing on data from the International Energy Agency (IEA), ranked the top African countries by electricity production, with South Africa, Egypt, Algeria, Nigeria and Morocco emerging as the continent’s leading power producers. South Africa alone generated about 234,850 GWh of electricity, accounting for more than a quarter of Africa’s total output, while Egypt followed closely with over 208,000 GWh. Algeria produced over 91,000 GWh, underscoring the dominance of North and Southern African economies in large-scale electricity generation.

The ranking reveals a central reality about Africa’s energy landscape. Electricity production is closely tied to industrialization, urbanization, and access to large-scale generation infrastructure. Most of the leading producers rely heavily on fossil fuels, particularly coal and natural gas. South Africa’s electricity sector remains coal-dependent, Egypt and Algeria are driven largely by natural gas, while Morocco has accelerated investments in renewables to diversify its energy mix.

Ghana does not appear among the top five electricity producers on the continent, yet its energy story is significant for a different reason. Unlike many African countries struggling with electrification, Ghana has achieved one of the highest electricity access rates in sub-Saharan Africa, reaching approximately 85 percent according to IEA assessments. This positions Ghana as an important case study in balancing electricity access, generation diversity, and regional energy trade despite its comparatively smaller generation capacity.

Ghana’s electricity system is built on a diversified mix of hydropower, thermal generation and emerging renewable energy sources. Historically, hydropower from the Akosombo Dam formed the backbone of the country’s electricity supply. However, increasing demand, climate variability and periodic low water levels have forced Ghana to expand thermal generation, particularly gas-fired plants. Current estimates suggest thermal generation now contributes roughly two-thirds of Ghana’s electricity production, while hydro contributes about one-third.

This transition reflects both progress and vulnerability. On one hand, Ghana has improved supply reliability and strengthened its position as a regional electricity exporter to neighbouring countries such as Togo, Benin and Burkina Faso. On the other hand, dependence on thermal generation exposes the country to fuel supply disruptions, currency pressures and rising emissions. The recurring national concern over “dumsor”, i.e prolonged power outages, demonstrated how fragile electricity systems can become when generation capacity, fuel supply and transmission infrastructure are not fully synchronized.

Compared with the continent’s leading electricity producers, Ghana’s strategy appears less focused on sheer volume and more centered on access expansion and energy stability. This distinction matters. South Africa may produce vastly more electricity, but it continues to battle rolling blackouts due to aging coal infrastructure and operational inefficiencies. Ghana, despite smaller output, has pursued incremental reforms in transmission, independent power production and renewable integration.

The next phase of Ghana’s electricity efforts will likely depend on renewable energy expansion. The IEA projects stronger roles for solar PV and cleaner energy technologies in Ghana’s future electricity mix as demand continues to rise toward 2040. This aligns with broader continental and global energy trends, where solar energy is becoming increasingly central to power growth and energy transition efforts.

Ultimately, the comparison between the IEA ranking and Ghana’s electricity trajectory highlights two different dimensions of energy development in Africa. The top producers dominate through industrial-scale generation, while Ghana demonstrates how strategic diversification and expanding access can create a relatively resilient energy system in a lower-output economy. As Africa’s electricity demand grows alongside industrialization and population expansion, Ghana’s energy sector challenge will be to scale production sustainably without sacrificing affordability, reliability or environmental goals.
