Pan-African renewable energy company WeLight has announced a $650 million investment to expand solar mini-grid infrastructure in Nigeria. The project aims to provide reliable, clean electricity to underserved and rural communities that currently rely on expensive diesel and petrol generators. By deploying decentralized solar photovoltaic systems with lithium-ion battery storage, the initiative seeks to power both residential homes and commercial activities, such as agriculture and small-scale manufacturing. While a specific timeline has not been announced, the move follows a recent $31 million funding round supported by the International Finance Corporation.
