Overview

In 2024, as part of its Project Zero strategy, MTN Uganda focused on improving energy efficiency to reduce emissions, strengthen infrastructure reliability, and improve operational resilience. Key interventions included the installation of lithium-ion batteries, generator replacements, rectifier upgrades, and the deployment of Automatic Voltage Stabiliser (AVS) at two regional data centres.

 The AVS initiative was implemented to address ongoing voltage fluctuations that had contributed to excessive generator use and power inefficiencies. Since the installation, voltage levels have stabilised, protecting sensitive equipment from potential damage and significantly reducing generator run hours.

Response

Uganda faces growing energy demand and high carbon emissions due to its reliance on diesel-powered generators for backup power. Frequent voltage fluctuations not only increase fuel consumption and operational costs, but also lead to premature equipment failure and inefficiencies. To address these challenges, MTN Uganda needed a solution to stabilise power supply, reduce generator dependence and improve energy efficiency, ultimately lowering carbon emissions and enhancing network resilience. In 2024, MTN Uganda achieved a 58.40% reduction in Scope 1 and 2 emissions against a target of 12.5%. The actual emissions reduction achieved was 6 935tCO2e. This case study illustrates the successful application of the Reduce pillar of MTN’s Net Zero philosophy.

Emissions reduction

The project reduced 3.11tCO2 emissions in 2024.

Cost savings

Achieved monthly cost saving of US$289.32, with projected annual savings of US$3 471.78.

Improved operation resilience 

This initiative focused on power stability, including voltage drops, by ensuring that equipment operates within the required voltage range.

Outlook

MTN Uganda remains committed to advancing its tailored emissions reduction plan and strengthening its infrastructure to support long-term sustainability goals. The business will continue to implement efficiency-focused upgrades, optimise power use, and invest in scalable technologies to support its Net Zero ambition.
