The Eskom crisis
Loadshedding — South Africa's electricity emergency
Since approximately 2007, South Africa has experienced "loadshedding" — deliberate rolling blackouts where sections of the grid are switched off for 2–4 hour blocks to prevent total grid collapse. At its worst in 2023, loadshedding reached Stage 6 — meaning 6,000 MW was unexpectedly unavailable — causing up to 12 hours per day of blackouts that cost the economy approximately R500 million–R1 billion per day.
Eskom's ageing coal fleet:
Eskom operates approximately 15 coal power stations totalling approximately 37 GW. The average age is over 30 years — well past the typical 40-year design life of coal plants. Key problem plants: Medupi (24.51°S 28.20°E, 4,764 MW) — meant to be South Africa's saviour from load shedding when announced in 2007, but suffered massive construction delays, design flaws (boiler cracking), and took 15 years to reach full operation. Kusile (26.34°S 29.10°E, 4,800 MW) — even more troubled than Medupi, with units entering and leaving service intermittently due to structural failures. Eskom's energy availability factor (the percentage of generation capacity actually available) fell from approximately 80% in 2010 to approximately 55% in 2022–23. Root causes: deferred maintenance from years of budget cuts, sabotage (disputed but alleged), corruption in parts procurement (cables, boiler components), skills shortages as experienced engineers retired. The South African government's response: separating Eskom into generation, transmission, and distribution entities (Eskom unbundling), recruiting international expertise, and emergency REIPPP procurement.

REIPPP — the renewable success amid the crisis:
The Renewable Energy Independent Power Producer Programme (REIPPP) is South Africa's competitive renewable energy auction — and one of the world's most admired examples of attracting private investment into renewables in a developing economy. Since 2011, 92 projects totalling approximately 10 GW have been contracted across wind (Northern and Western Cape, Vredendal area 31.68°S 18.51°E), solar PV (Northern Cape, Upington area 28.46°S 21.26°E), concentrated solar power (CSP), and small hydro. Bid Window 5 (BW5, 2021) set a record South African price of approximately R0.45/kWh for solar (~$0.025/MWh) — demonstrating that competitive renewable procurement is possible even in South Africa's difficult investment environment (high WACC due to country risk). The REIPPP's success contrasts starkly with Eskom's failures — private IPPs have delivered projects on time and on budget while state-owned Eskom's new-build has been catastrophic. This contrast has been a powerful argument for IPP-based electricity market reform. Source: REIPPP programme documentation · IPP Office South Africa.

Questions
Questions about South Africa's energy
Why hasn't South Africa's JETP delivered faster results?
South Africa's $8.5 billion JETP (announced COP26, November 2021) was the world's first Just Energy Transition Partnership and generated enormous attention. But by 2024, the pace of actual financing and project delivery has disappointed. The reasons are structural and practical: (1) Composition of finance: Of the original $8.5 billion, approximately $800 million was grants, approximately $7.7 billion was concessional and commercial loans. South Africa has significant existing debt (Eskom's R400+ billion debt burden) — additional loans, even at concessional rates, increase debt service obligations. (2) Conditions complexity: International financial institutions attached conditions — governance reforms, Eskom restructuring milestones, anti-corruption measures — that are politically difficult to implement quickly. (3) Institutional bottleneck: South Africa's Presidential Climate Commission (PCC) developed the Just Energy Transition Investment Plan (JETP-IP) — but translating this plan into bankable projects requires extensive regulatory and legal work. (4) Energy crisis prioritisation: Eskom's loadshedding has forced South Africa to prioritise restoring existing generation capacity over building new clean capacity. Emergency diesel generators, IPP procurement, and rooftop solar have been faster than JETP-financed projects. (5) Currency risk: International loans in USD or EUR create foreign exchange risk for South African borrowers who earn revenue in Rand. The JETP experience has been studied by Indonesia, Vietnam, and other countries considering JETPs as a model — the lesson being that headline pledge numbers must be supported by simple, accessible, grant-heavy financing with minimal conditions to deliver impact.
