By adopting a site energy solution that combined solar and diesel to create a stable and reliable power supply for base stations, Safaricom, Kenya's largest operator was able to expand its business in the off-grid areas, and at the same time, reduce energy-related costs. Across the high-stakes telecom corridors of Sub-Saharan Africa of South Africa, Nigeria, and East Africa, the “diesel-only” power model has shifted from standard practice to a clear financial liability. This effectively. From 310 base transmission stations powered by solar in 2022, the number has grown to 1,432 in 2023 and will continue to grow as the company looks to use less energy, cut costs, and meet its sustainability goals. System Operation Daytime: Solar energy powers the telecom load and simultaneously charges the lithium. The project involved engineering, supply and installation of solar + diesel generator hybrid systems to power telecom BTS tower sites in areas not served by electricity grid. Location: Kenya Technical: 11 x 34KW ground mounted (fixed) solar panels, inverters, charge controllers, diesel generators.
