Millions of people across Africa live with frequent power cuts, but Malawi is testing a technology that could help change that. In Lilongwe, a giant battery storage system is being used to support the electricity grid, reduce blackouts, and make better use of the country’s growing solar power capacity. For business owners like welder Hotan Yuda, more reliable electricity could mean lower costs and new opportunities for growth. Supporters say the technology can also reduce reliance on diesel generators and cut carbon emissions. Could this massive “power bank” become a model for expanding renewable energy access across Africa?
