How does the Current Energy Crisis of Load-shedding Impact Fibre Internet in South Africa?

Loadshedding Crisis and its Impact on Fibre Internet in South Africa


The ongoing energy crisis in South Africa, primarily attributed to insufficient generation capacity, is impacting the provision of reliable fibre internet in the country. The loadshedding issue, a consequence of the power supply problem, particularly hampers the efficiency of the country’s digital infrastructure, causing frequent internet disruptions. Loadshedding, essentially a rationing of electricity, interrupts power to fibre optic network infrastructure, resulting in service disruption. This issue is particularly exacerbated considering the age of South Africa’s power infrastructure, with a significant proportion of power stations nearing decommissioning, reducing their efficiency and increasing their risk of breakdown.

The erratic power supply not only directly impacts internet uptime but also strains the resources of ISPs (Internet Service Providers). These ISPs are forced to deploy backup power solutions to ensure continuity of service during load shedding periods. However, providing these alternative power sources is both costly and logistically challenging. A survey from 2021 indicated that more than half of the internet service providers experienced a 75% increase in their operating costs due to the additional infrastructure needed to maintain service during load shedding. This also causes an increase in internet prices, which further exacerbates the digital divide in a country where just over half of the population have internet access as of 2022.

Loadshedding and the energy crisis have long-term implications for the digital economy of South Africa. The continual loadshedding threatens the digital progress. A study from 2022 found that South African businesses lose an average of 5% productivity during load shedding, primarily due to the interruption of digital services. This inefficiency places a significant economic burden on the country and threatens South Africa’s position as a leading digital economy on the African continent.

The Loadshedding Crisis

The loadshedding crisis in South Africa, primarily attributed to the state power utility Eskom’s inability to meet the country’s electricity demand, has become a significant issue for businesses and homes. Power outages disrupt daily activities, often with little to no warning. Unpredictable power interruptions, ranging from a few minutes to several hours, are undermining the country’s productivity, economic stability, and digital transformation efforts.

Energy Crisis and It’s Impact on Fibre Internet Infrastructure

Fibre internet infrastructure relies on consistent and reliable energy supply. When load shedding occurs, it directly impacts the operation of this infrastructure.

  1. Data Centres: These critical components of the digital economy house the servers that keep websites, apps, and various online services running. Power interruptions can lead to service outages and data loss if backup systems fail or cannot provide power for prolonged periods.
  2. Network Equipment: Fibre infrastructure includes various devices like fibre optic cables, switches, routers, and other network equipment that require constant power to function. Power cuts interrupt these services, leading to internet outages.
  3. Service Providers: Internet Service Providers (ISPs) themselves require power to manage and monitor the network. Load shedding could hinder their operational capacity, disrupting service provision to consumers.
  4. End-User Equipment: Devices like modems, routers, or any other equipment on the user’s side need electricity to connect to the internet. When there is a power outage, these devices go off, causing connectivity issues even if the broader internet infrastructure is working.

Mitigating the Impact

Many service providers and data centres are mitigating the impact of load shedding by investing in alternative power sources, like Uninterrupted Power Supply (UPS) systems, generators, and solar power. However, these solutions can only provide power for a limited duration, and they significantly increase operational costs.

End users can also employ UPS systems and generators to keep their devices running during power cuts. However, this isn’t a feasible solution for many due to the high costs and maintenance requirements of these backup systems.

Innovative power solutions, such as green and renewable energy sources, are being considered, but they require substantial investment and infrastructure.


The load shedding crisis in South Africa has a profound impact on the fibre internet landscape. It not only disrupts service and stifles digital growth but also places a significant financial burden on providers and consumers alike to maintain connectivity during power outages. Despite these challenges, the crisis has underscored the need for energy-efficient solutions and the exploration of renewable energy sources. Addressing the energy crisis is key to ensuring the continuous growth of South Africa’s digital economy and facilitating its journey towards a more connected future.
