End of Loadshedding: Eskom Recovery Plan Stabilizes South Africa Power Supply

South Africa has gone six consecutive months without loadshedding -- the government euphemism for rolling blackouts -- marking the longest period of uninterrupted electricity supply since 2018 and the most tangible evidence yet that the country's power crisis, which cost the economy an estimated $50 billion over the past decade, may finally be easing.

The achievement, confirmed by Eskom's System Operator on April 15, is the result of a convergence of factors: the gradual improvement in the performance of Eskom's aging coal fleet, the contribution of new renewable energy capacity from independent power producers (IPPs), the commissioning of emergency power procurement projects, and the extraordinary growth of rooftop solar installed by households and businesses seeking to insulate themselves from grid unreliability.

Eskom's Energy Availability Factor (EAF) -- the percentage of installed generation capacity available to produce electricity -- has improved from a nadir of 48 percent in early 2023 to approximately 62 percent in the first quarter of 2026. While this remains below the target of 75 percent, the improvement reflects the success of Eskom's Generation Recovery Plan, launched in 2023 under the leadership of then-CEO Andre de Ruyter and continued under current CEO Dan Marokane.

The recovery plan has focused on three priorities: the reduction of unplanned breakdowns ("breakdowns" or "partial load losses" in Eskom terminology) through intensified maintenance, the addressing of chronic skills shortages at power stations, and the improvement of coal supply logistics. Eskom completed scheduled maintenance outages at 14 of its 15 coal-fired power stations between 2024 and early 2026, replacing worn boiler tubes, turbine components, and pollution control equipment. The utility has also recruited approximately 1,200 engineers and technicians since 2024, partially addressing a critical skills gap that had been eroded by retirements and attrition.

The Koeberg nuclear power station, Africa's only nuclear facility, has been a critical contributor to grid stability. Koeberg's Unit 2, which was taken offline for a refueling outage and the replacement of its steam generators in December 2025, returned to service on March 15, 2026, adding 920 MW of baseload generation to the grid. Koeberg's operating license has been extended by 20 years to 2045, ensuring that the facility will continue to contribute to South Africa's power supply for the next two decades. The replacement of steam generators at both units, completed at a cost of approximately $600 million, was one of the most complex engineering projects ever undertaken on the African continent and was executed by a consortium of French and South African engineers.

Renewable energy from independent power producers has added approximately 4.2 GW of new capacity to the grid since 2023. The Renewable Energy Independent Power Producer Procurement Programme (REIPPPP), which had been stalled for several years, was revived through Bid Window 6 (awarding 2.6 GW in 2023), Bid Window 7 (awarding 1.8 GW in 2024), and Bid Window 8 (awarding 3.2 GW in early 2026, with projects under development). The bulk of the new capacity is wind power from the Eastern and Western Cape, supplemented by solar PV installations in the Northern Cape, Free State, and North West provinces.

The emergency power procurement program, launched in 2020 to address immediate supply gaps, has delivered 1.8 GW of capacity from projects including the 300 MW Scatec solar project in the Northern Cape, the 150 MW ACWA Power concentrated solar power project, and several gas-fired peaking plants operated by independent operators. While the cost of emergency power has been higher than anticipated -- averaging $0.18 per kilowatt-hour compared to $0.08 per kilowatt-hour for Eskom's coal generation -- the capacity has been essential for covering peak demand periods.

The growth of embedded generation -- electricity generated by businesses and households that is not fed into the national grid -- has been the most remarkable aspect of South Africa's power landscape transformation. An estimated 4.5 GW of rooftop solar has been installed since 2022, with large commercial and industrial users accounting for approximately 60 percent of installations. Mining companies including Anglo American, Gold Fields, and Harmony Gold have installed combined solar capacity exceeding 1 GW at their operations, significantly reducing their dependence on the grid.

The end of loadshedding has been welcomed by South African businesses, which have borne the brunt of the power crisis. Business Leadership South Africa (BLSA), which represents the country's largest corporations, estimated that loadshedding cost the economy $50 billion between 2014 and 2025 in lost production, increased costs, and reduced investment. The organization's CEO, Busi Mavuso, described the return of stable electricity as "the single most important positive development for the South African economy in a decade."

However, analysts have cautioned against declaring victory. Eskom's coal fleet, with an average age of 38 years, remains fragile and susceptible to breakdowns. Several of the utility's newest stations -- Medupi and Kusile, both designed to produce 4,800 MW each -- have been plagued by design defects and construction quality issues that continue to limit their output. Medupi is currently producing approximately 3,200 MW instead of its design capacity, and Kusile is producing approximately 3,500 MW. Full remediation of these issues is not expected before 2029.

Eskom's financial position, while improved, remains precarious. The utility's debt stands at approximately $25 billion, and it continues to rely on government guarantees to service its obligations. The National Treasury has allocated $3.5 billion in fiscal support to Eskom for the 2026-27 financial year, on top of the $60 billion in bailouts provided since 2008. The utility's tariff increase application for 2026-27, which requests a 12 percent increase, has drawn opposition from consumer organizations and the mining sector.

The just energy transition from coal to renewables presents both an opportunity and a challenge. South Africa has secured $8.5 billion in international financing through the Just Energy Transition Partnership (JETP), announced at COP26 in 2021, to support the decommissioning of coal power plants and the development of renewable energy and green hydrogen. The decommissioning of the first three coal power stations (Komati, Hendrina, and Grootvlei) has begun, but the pace of decommissioning must be balanced against the need to maintain adequate supply.

For ordinary South Africans, the end of loadshedding is a relief that is difficult to overstate. For a decade, the daily uncertainty of whether the lights would stay on -- whether children could study, businesses could operate, hospitals could function, and traffic lights would work -- was a source of immense frustration and economic damage. The recovery is real, but it is fragile. South Africa's power system has been stabilized, not transformed. Building a power system that is reliable, affordable, clean, and capable of supporting economic growth for the next generation remains the defining infrastructure challenge of Africa's most industrialized economy.
