Feasibility Assessment

NTCSA licensed: received operating licence under the Electricity Regulation Act in 2025, confirming legal and operational separation from Eskom generation. Financial capitalisation — the Transmission Development Plan 2025–2034 requires an estimated R440 billion, with R112 billion approved for its first five years — 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.

Description

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 R440 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.

🇧🇷Brazil1999

Brazil expanded one of the world's largest transmission networks by auctioning individual line concessions to whoever would build and operate them for the lowest annual revenue. The regulator specifies the route, the voltage and the in-service deadline; the winner finances and builds the line and is then paid a fixed annual permitted revenue for keeping it available, independent of how much energy flows over it. System operation stayed with an independent operator, so no builder controls dispatch. The design pulled private and state capital into transmission for two decades, and it is the closest available answer to how a ring-fenced transmission company finances a grid build-out it cannot fund from its own balance sheet.

Approach

Each line or substation is tendered as a separate concession. The regulator fixes the technical specification, the in-service deadline and a revenue ceiling; bidders compete by discounting the annual permitted revenue they will accept, and the winner carries construction and financing risk across a thirty-year concession. Payment is for availability rather than throughput, so the asset is bankable against a regulated cash flow instead of against demand. Penalties for unavailability and for missing the in-service date sit in the contract, and system operation is vested in an independent operator outside every concessionaire.

Timeline: Independent system operator created 1998 and the regulator shortly before it; transmission concession auctions from 1999 on thirty-year terms, run as a continuous pipeline since

Lessons for South Africa

NTCSA's constraint is capitalisation: an estimated R440 billion Transmission Development Plan against a balance sheet only just separated from Eskom's. Brazil's answer is that the transmission company need not own every line. Auctioning defined line concessions paid an availability-based regulated revenue brings third-party capital onto the grid without waiting for state equity injections, and it prices each build directly rather than through a NERSA determination on the whole regulated asset base. The two-to-four-year NERSA approval bottleneck would have to move first: an auction only works if route, licence and deadline are settled before bidders are asked to price them.
