“Medupi and Kusile will remain central to South Africa’s electricity supply for many years to come,” Eskom affirmed in a recent statement. The stations boast an operational lifespan of roughly 50 years, indicating a long-term solution for the nation’s energy needs.
A Turning point in Load Shedding?
the inclusion of Unit 6’s output into the Energy Availability Factor (EAF) calculations will be pivotal in assessing Eskom’s overall performance.Notably, Eskom’s EAF has already risen to levels not seen in four years, surpassing 70%. At these performance levels, the need for load shedding – the rolling blackouts that have plagued South Africa – diminishes substantially.
The nation has experienced 135 consecutive days without load shedding, with only 26 hours of outages recorded between April 1st and september 25th, 2025. This positive trend fuels optimism, even though both Eskom and the Department of Energy have yet to officially declare an end to the practice.
Despite the positive shift,energy demand has decreased somewhat,influenced by both consumers adopting alternative energy sources and escalating energy costs. The electricity grid requires additional capacity to support future economic growth and to address the impending decommissioning of older generating units in the coming decade.
Renewable Energy Expansion
Eskom is actively accelerating its investments in renewable energy sources. The company recognizes the necessity of complementing its baseload infrastructure with enduring alternatives to ensure a diversified and resilient energy mix for the future.
