A total of 1,500 base transmission stations are now fully powered by solar energy, marking a significant transformation that is changing how the Safaricom network operates.

Popularly referred to as boosters, base transmission stations keep customers connected. Whether it’s making a call or sending money, these sites form the silent backbone of our digital lives.

Initially, each booster relied on diesel generators that kicked in during power outages.

The shift to solar power began in 2022, with 310 sites located in areas that were off the national grid and entirely relied on diesel generators. Today, that number has grown to over 1,500 solar-powered sites,

The use of solar energy has improved network stability by reducing breakdowns, particularly those related to mechanical power systems, such as generators.

Solar hubs have also expanded to large hub sites and data centres, helping to meet the increasing energy demands as the network grows.

This is part of Safaricom’s broader strategy to achieve net-zero emissions by 2050 and reduce its carbon footprint.

The distribution of sites across the country has necessitated partnerships and internal team development to ensure the proper implementation of this program.  This solar power transformation has resulted in the greatest ever carbon reduction at the company since targets were set in 2016, and decreased dependence on diesel by 39 per cent across Safaricom’s network.

As more boosters switch to solar, the goal is not just to power a network, but to build a cleaner, more sustainable future.
