Zambia’s telecommunications industry is facing significant challenges due to prolonged power blackouts across the country. The Global System for Mobile Association of Zambia (GSMAZ) has raised concerns about the negative impact these outages are having on the sector’s ability to provide quality services to customers.
MTN Zambia, Airtel Zambia, and Zamtel, which collectively form the GSMAZ, have issued a joint statement highlighting the detrimental effects of power cuts lasting more than four hours. These extended outages are compromising service quality and increasing operational costs for mobile network operators.
The root cause of these power cuts can be traced back to January 2023, when severe climate change and unpredictable weather events led to a drastic reduction in water levels at Lake Kariba, the world’s largest man-made lake by volume. This environmental crisis resulted in a significant decrease in electricity generation capacity for both Zambia and Zimbabwe.
ZESCO, Zambia’s state-owned power utility, was forced to increase the duration of blackouts from six to 12 hours in response to the diminished power generation. The situation has deteriorated further, with current load shedding periods extending up to 13 to 14 hours daily.
The GSMAZ emphasized that Zambia is experiencing its worst climate change effects in the last 60 years of independence. The impact is felt across all sectors and levels of society. The telecom industry, with over 3,500 combined tower sites connected to the national grid, is particularly vulnerable to these power disruptions.
Mobile network operators are facing substantial cost increases due to the need for constant refueling and more frequent servicing of backup generators. The power backup systems at telecom sites are typically designed to last up to four hours, but the extended load shedding periods have pushed these systems beyond their intended capacity.
In response to this crisis, GSMAZ members are collaborating with tower providers, regulators, and other stakeholders to develop sustainable solutions. Among the medium to long-term measures being considered are solar-based backup solutions to enhance energy resilience.
The energy crisis affecting Zambia’s telecom sector is not unique to the country. Across Africa, telecom operators are grappling with similar challenges and implementing innovative solutions to protect their infrastructure and maintain service quality.
In South Africa, for example, telecom companies have been dealing with deliberate “load shedding” implemented by Eskom since 2007. MTN SA invested significantly in 2023 to move its base stations off-grid, while Vodacom SA entered into a “virtual wheeling agreement” with Eskom to accelerate efforts in solving the country’s energy crisis.
These initiatives demonstrate the proactive approaches being taken by telecom operators across the continent to address power supply challenges. As climate change continues to impact energy production and distribution, the telecommunications industry must adapt and innovate to ensure reliable services for their customers.
The situation in Zambia underscores the critical role of the telecommunications sector as an economic enabler for sustained business growth and social development. As the country navigates this energy crisis, finding sustainable solutions will be crucial for maintaining connectivity and supporting economic progress.
