Across Africa, diesel generators have long filled the gap left by unreliable grid infrastructure. Homeowners and businesses rely on them as backup or alternative power but the costs are often significant. According to analysis by the Energy for Growth Hub, electricity from diesel generators typically runs three to five times more expensive than grid power across sub-Saharan Africa. As solar and storage costs plummet, battery storage appears positioned to take the place of diesel generators and offer a cheaper, cleaner alternative.

In fact, a recent report from Ember and Africa Tech Futures Lab referred to batteries as “the new diesel generator”, highlighting that the technology is being increasingly treated as core infrastructure essential to keeping energy access consistent as renewables scale.

Large-scale battery imports

Africa's shifting import patterns reveal how quickly batteries are becoming essential infrastructure. Ember and Africa Tech Futures Lab’s report found that while the value of solar panel imports into Africa has doubled since 2024, the value of battery imports has quadrupled over the same time period.

Nigeria leads Africa in lithium battery imports at around $750 million in the twelve months to June 2026, more than double its $300 million in solar panel imports. Ember and African Tech Futures Lab attribute this to households and businesses substituting battery storage for diesel generators during loadshedding hours.

South Africa ranks second at nearly $550 million in battery imports. It is Africa's largest battery energy storage market for operational projects, having adopted these systems earlier than most neighbours in response to loadshedding.

The Democratic Republic of Congo follows at over $400 million, with battery imports also outpacing solar. Here, battery imports are linked to 24-hour solar-plus-storage schemes at copper mines to replace diesel, Ember and African Tech Futures Lab says.

The 15 countries in Africa with the highest value of Chinese battery exports are Egypt, Mali, Kenya, Morocco, Zimbabwe, Zambia, Uganda, Sudan, Senegal, Cote d’Ivoire, Algeria and Chad. From this list, Mali, Zimbabwe, Uganda and Chad are currently importing a larger value of batteries than solar panels.

Falling costs

Price economics continue to strengthen the case for battery storage. According to Bloomberg NEF's 2025 lithium-ion battery price survey, pack prices dropped 8% in 2025 to a record low of $108/kWh, following a steeper 20% decline in 2024, when prices fell from $139/kWh to $115/kWh. Since 2010, battery pack prices have fallen 93%, from $1,474/kWh, when adjusted for 2025 dollars.

Though the rate of decline is moderating due to rising raw material prices, BloombergNEF forecasts prices will dip below $105/kWh in 2026.

These economic implications are substantial. Billions flowing into battery imports signal investor confidence in Africa's renewable energy future, whilst also exposing the continent's reliance on Chinese manufacturing.

As costs decline further, opportunities may emerge for local assembly and value creation. Battery adoption also sidesteps the volatile geopolitics of fuel markets, where diesel price shocks can destabilize economies.

Towards distributed grids

The shift from diesel to battery storage represents a fundamental realignment in how Africa approaches energy independence. Rather than waiting for centralized grid expansion that often fails to reach rural and remote communities, battery storage can help African countries build local, distributed energy systems.

In their report, Ember and African Tech Futures Lab explain that batteries and solar will “enable African countries to leapfrog to a new distributed grid, skipping the need to build a large national grid.”

“The majority of electricity generation can be where it is used, day and night – either on rooftops directly, or embedded in MW scale (instead of GW scale) in the local grid,” the report explains. “Only a small grid is then needed to help balance supply and demand.”

This democratisation of energy access has the potential to unlock economic activity and bring electricity access to millions across the continent. Ember and Africa Tech Futures Lab’s report highlights that this transition has already begun, indicating that the question is no longer whether batteries will replace diesel generators, but how quickly and completely the transition unfolds.

What is means

Africa’s accelerated rollout of battery storage brings immediate implications. Renewable developers may benefit from a market seeking out distributed solar-plus-storage systems, particularly in off-grid and underserved areas. Equipment suppliers and installers will likely see growing demand, but perhaps also pressure to localise assembly and drive down costs further.

Policymakers face regulatory challenges, including ensuring quality and safety standards are met and managing a grid that evolves from centralised to distributed. The batteries Africa is importing today are laying the groundwork for energy systems that will look fundamentally different from those in other parts of the world.
