Malawi Turns to Battery Storage for Grid Resilience

Malawi is turning to battery storage, seeking to reduce the climate risks facing its electricity system and build a more reliable platform for renewable energy growth.

The country has commissioned its first standalone utility-scale Battery Energy Storage System (BESS), a 20MW/40MWh installation at Kanengo in Lilongwe. Developed by the Electricity Supply Corporation of Malawi (ESCOM) with support from the Global Energy Alliance for People and Planet (GEAPP), the project is backed by a US$20 million catalytic grant.
The investment comes after a series of climate-related disruptions exposed the vulnerabilities of Malawi’s hydropower-dependent grid.

Cyclones Anna and Freddy damaged electricity infrastructure, while drought has periodically reduced water availability for generation, forcing businesses and essential services to rely on costly diesel backup.
The Kanengo BESS is designed to provide rapid-response grid support while enabling greater use of renewable power. The system is expected to help unlock around 100MW of renewable electricity previously curtailed, reduce diesel dependence and avoid more than 10,000 tonnes of carbon emissions annually.

Unlike conventional generation assets, batteries do not produce electricity. They store surplus power and release it when demand rises, or renewable generation falls, providing services such as frequency regulation and voltage support.
For Malawi, that flexibility could prove increasingly valuable as climate volatility intensifies.

Grid reliability remains a major constraint on economic activity. Manufacturers face production losses during outages, while small businesses often incur higher operating costs when forced to switch to diesel generators.

The implications extend to agriculture, where dependable electricity is increasingly important for irrigation, agro-processing and cold-chain infrastructure.
A more stable grid could therefore improve not only electricity reliability but also the economics of productive sectors that depend on continuous power.

The project could also strengthen Malawi’s position in the Southern African Power Pool (SAPP), particularly as regional electricity trading expands.

Malawi already has an interconnector with Mozambique, while links with Zambia and Tanzania are planned or under development. Greater grid stability would improve the country’s ability to participate in cross-border electricity markets and manage fluctuations in supply and demand.

The initiative also includes a Southern Africa BESS Centre of Excellence at Mzuzu University, intended to develop skills in battery operations, grid modelling and system integration.
For GEAPP, Malawi offers a potential blueprint for wider deployment of storage across Africa. The organisation is targeting 90GW of battery storage globally and sees local technical capacity as critical to scaling projects.

As African power systems add more solar and wind while facing increasingly severe climate risks, battery storage is emerging as more than a balancing technology. For Malawi, it is becoming a strategic piece of climate-resilient energy infrastructure.
