South Africa’s Electricity Minister Warns of Power Supply Strain Amid Ongoing Challenges

South Africa’s power supply remains under significant strain, with Minister of Electricity Kgosientsho Ramokgopa admitting that keeping the lights on is one of the key issues that “give me sleepless nights.” The country continues to face risks of power outages as unplanned breakdowns persist, and delays in bringing new energy projects online further threaten stability.

Electricity Grid Under Pressure

Speaking at a conference in Cape Town, Ramokgopa acknowledged the immense strain on South Africa’s power grid. Eskom, the state-owned power utility that provides over 80% of the country’s electricity, has struggled to meet demand.

While load shedding—a term used for rolling blackouts—was halted in March 2024 due to improved maintenance and delayed decommissioning of older plants, the energy supply remains fragile. Intermittent power cuts have occurred in recent months, raising concerns about the system’s reliability, especially as winter approaches.

The vulnerability of South Africa’s power infrastructure was highlighted recently when one of two reactors at the Koeberg nuclear plant unexpectedly tripped.

The Return of Load Shedding?

Eskom reintroduced Stage 6 load shedding on February 23, cutting 6,000 megawatts of generation capacity from the grid to prevent a total blackout. Energy analysts warn that systemic weaknesses remain a threat, and further load shedding could be on the horizon as demand surges in colder months.

Jason Lightfoot, a portfolio manager at Futuregrowth Asset Management, expressed concerns over the situation, stating that “as winter draws near, we need to consider the consequences of this instability and the risk of further load shedding.”

Eskom’s Long-Term Strategy

Over the next decade, Eskom plans to decommission coal-fired plants with at least 15 gigawatts of capacity. To fill the gap, the utility has been working on renewable energy projects expected to add 2,000 megawatts to the grid over the next three years.

Despite this, government-backed power procurement programs have faced multiple delays. The first bid window for a 2,000-megawatt gas-fired power project was recently extended by seven months to allow time for bidders to clarify critical issues.

Private Sector and Renewable Energy Solutions

Private power generation has played a crucial role in easing South Africa’s electricity crisis. In 2024, the National Energy Regulator of South Africa registered a record 501 new private energy facilities with a combined capacity of 4,178 megawatts. This shift to decentralized power sources has helped mitigate some of Eskom’s supply challenges.

Key Energy Challenges Ahead

Beyond power generation, South Africa faces additional hurdles in securing energy stability. The country needs a financing solution to upgrade 14,000 kilometers of transmission lines—an issue Ramokgopa expects to resolve by the end of the year.

Another pressing concern is the looming “gas cliff.” South Africa currently imports gas via pipeline from Mozambique, but those supplies are expected to run out in the near future. The government is working with Eskom and Sasol to access liquefied natural gas (LNG) from Qatar, but this could drive up costs.

Looking Ahead

South Africa’s power supply challenges remain a pressing issue, with government and private sector efforts focused on finding sustainable solutions. While short-term improvements have provided some relief, long-term energy security will require a mix of renewables, infrastructure upgrades, and stable fuel supplies.

As the country heads into winter, Eskom’s ability to keep the grid stable will be put to the test once again.
