Theme: Electricity infrastructure
Responsible: DMRE / Eskom/NTCSA / National Treasury
NTCSA licensed: received operating licence under the Electricity Regulation Act in 2025, confirming legal and operational separation from Eskom generation. Financial capitalisation — estimated R180 billion over 10 years for transmission infrastructure — is the next critical milestone, targeted for 2026/27. Battery Energy Storage Programme Round 1 procurement is underway. NERSA approval processes for transmission projects remain a 2–4 year bottleneck requiring regulatory reform. The grid expansion investment is the binding constraint on absorbing Bid Window 7's 3,940 MW of new renewable capacity.

Eskom supports National Transmission Company capitalisation as essential for grid reliability during the transition.

Treasury supports the National Transmission Company in principle but requires a clear capitalisation plan that does not expand government guarantees.
Interest: Fiscal consolidation with public debt stabilising below 75% of GDP; structural reforms that improve revenue without expanding contingent liabilities;…
Concern: Unfunded mandates in energy transition (JETP co-financing); Eskom's R400bn+ debt and how restructuring socialises costs; reform proposals that create…

The National Transmission Company SA (NTCSA) is being established as a standalone transmission system operator, legally ring-fenced from Eskom, to operate and expand South Africa's 33,000 km high-voltage grid. Capitalisation is the critical constraint: NTCSA requires an estimated R300 billion over ten years to implement the Transmission Development Plan, address the renewable energy connection queue backlog, and maintain ageing infrastructure. Funding options include direct state equity injections, development finance institution loans (DBSA, AfDB), and regulated asset base financing under NERSA-approved tariffs. Independent capitalisation also enables NTCSA to raise debt on its own balance sheet, separate from Eskom's distressed finances. As of early 2026, NTCSA's legal separation from Eskom remains in progress; full capitalisation and independent governance are prerequisites for the competitive electricity market to function.

South Africa needs R490 billion in new transmission infrastructure over the next decade — capital that cannot come from the fiscus alone; private investment under transparent regulation is the only viable path. — DBSA Transmission Infrastructure Report, 2025
Kenya expanded geothermal capacity from 45 MW (2000) to 878 MW (2023) — now 47% of installed capacity — through KenGen's Olkaria complex. The key innovation: a state-owned drilling company bore exploration risk (the highest-cost phase), with private developers entering only after wells were proven. Generation cost fell from USD 0.10 to USD 0.05/kWh. SA's geothermal potential is limited, but Kenya's public-bears-risk/private-operates model applies to any capital-intensive energy infrastructure such as battery storage or new transmission.
