We currently operate mini-grid projects in ten villages in Tanzania under the brand name “Rafiki Power”, supplying electricity to more than 4,000 people.

Although technology agnostic, our current mini-grid solution is a containerized solar PV and battery system, which provides high-quality grid-equivalent. Power distribution to customers is enabled with a 230V 50Hz AC mini-grid (single and three-phase). Customers are connected to the distribution grid with pre-paid smart-meters which enable mobile money payments and a fully automated control of the energy consumption.
