South Africa experiences unprecedented power cuts due to generation unit failures
The current energy crisis in South Africa has escalated to unprecedented levels, with Eskom, the state-owned power utility, implementing stage-6 load shedding.
This decision was prompted by multiple generating units at the Camden power station tripping, which significantly reduced the electricity supply available to the national grid. Prior to this, Eskom had already been applying stage-3 power cuts due to a temporary setback in generation capacity.
Load shedding refers to the intentional shutdown of electric power in parts of a power distribution system to prevent the entire system from failing when demand exceeds supply. In South Africa, this phenomenon has been a recurring issue since 2007, primarily attributed to insufficient generation capacity and aging infrastructure. The majority of electricity in South Africa is generated from coal-fired plants, many of which are nearing their operational lifespan and require frequent maintenance. This situation has led to regular breakdowns and unplanned outages.

Eskom’s fleet consists largely of coal-fired plants that have not been adequately maintained or replaced over the years. The last significant additions to Eskom’s generating capacity occurred between 1961 and 1996, with only limited expansions since then. The construction of new plants like Medupi and Kusile has faced numerous challenges including technical problems and cost overruns.
Current Situation
As of February 2025, Eskom has implemented stage-6 load shedding for the first time since its introduction in December 2019. This stage involves cutting off an additional 6,000 MW from the grid, which severely impacts daily life and economic activities across South Africa. The implementation of such high-level load shedding indicates a critical failure within Eskom’s operations and highlights ongoing issues related to governance, corruption, mismanagement, and sabotage within the organization.
The recent escalation follows a brief period in April 2024 where there were no rotational power cuts for an entire month—a first since January 2022—demonstrating how volatile the situation remains. However, by late January 2025, load shedding returned as generation capacity continued to fall short against rising demand.
The implications of these ongoing blackouts are profound. They affect not only residential consumers but also businesses that rely on consistent electricity supply for operations. The energy crisis is seen as symptomatic of broader governance issues within South Africa’s political landscape. Experts suggest that resolving this crisis will require substantial investment in new generation capacity along with improvements in management practices at Eskom.
