Thyspunt recommended for Eskom’s new nuclear power station

1. The Tuesday PDF that moved the front line

Late-March wind was still rattling the corrugated roofs of Cape St Francis when a 776-page file landed on Eskom’s nuclear portal. By sunset the download counter had spun past 3 000: surf-casters in Jeffreys Bay, marine archaeologists in Grahamstown, wind developers in Gqeberha and diplomats in Pretoria were all scrolling through the Draft Environmental Scoping Report. Nothing is final, but the chessboard just tilted: every borehole, wetland survey and heritage objection for the next three years will now zero in on Thyspunt, a dunefield 12 km west of the holiday village. Bantamsklip, the only remaining rival, has been waved into the stands with a polite “heritage-only” tag - code for “archive the maps, cancel the drill crews.”

The report’s release triggers a new countdown. Scoping is only Step 1 under NEMA, yet it fixes geography; once Minister Barbara Creecy endorses the terms, Step 2 - up to 28 specialist studies and another 18–24 months of public wrangling - becomes almost impossible to reroute. In other words, the PDF that slipped out on a random Tuesday redraws where South Africa may pour its next third-of-a-trillion rand.

2. Why 5 200 MW is a country-sized lever

South Africa can, on paper, call on 52 GW of plant; in midwinter reality, barely 26 GW sometimes show up. Dropping a 5 200 MW block onto the grid is therefore the energy equivalent of adding an extra Gauteng. Run at 90 % capacity, the station would deliver 41 TWh each year - roughly what Eskom currently generates by burning R30 billion worth of diesel in open-cycle turbines. The carbon arithmetic is equally stark: 18 million tonnes of CO₂-equivalent avoided annually, more than the tailpipes of every minibus taxi, bus and car in Cape Town combined.

Yet scale cuts both ways. One station equals three Koeberg-sized units; if construction repeats Medupi’s overruns, the country’s debt ratio balloons by another 2 % of GDP. Conversely, if the build stays on schedule, the Southern Cape could become the first region in Africa where baseload, wind and solar share a common 765 kV spine - potentially a template for the continent.

3. The site nobody fought for - until now

Latitude -34.19°, longitude 24.77°: Thyspunt is a 2 600 ha mosaic of wandering dunes, seep wetlands and fossil-rich aeolianite locked between the villages of Oyster Bay and St Francis. Eskom already holds 90 % of the surface; the remaining slivers are municipal coastal reserve. A 400 kV transmission corridor - built to ferry peaking power from Dedisa and Avon - passes 14 km inland and still has 3 500 A of head-room per phase, enough to export two reactor blocks without fresh servitudes. In grid jargon, Thyspunt is a “plug-and-play” location, a rarity in a country where every new power line triggers decade-long land-owner battles.

The landscape, however, is not empty. Dunes march south-east at 80 cm a year, burying wetlands listed as National Freshwater Ecosystem Priority Areas. The nearshore Benguela–Agulhas transition zone hosts the last viable spawning shoals of seventy-four seabream, a fish already fished to commercial extinction. And beneath the sand lie Middle Stone Age hearths dated 135 000–90 000 years before present - artefacts that underpin the Out-of-Africa-2 theory of early human dispersal. In January 2025, SAHRA turned the entire dunefield into a Provisional Grade I Cultural Landscape, instantly criminalising any soil disturbance until a heritage permit is granted. Eskom’s environmental team confesses it still has “no clarity” on how the 3 400 ha boundary was drawn; two private conservancies have briefed senior counsel to challenge the listing.

4. Bantamsklip: the postcard that could not pay its bills

Shift the lens 250 km west and the limestone ridge at Bantamsklip looks like an Instagram dream: black oystercatchers on sandstone boulders, Heaviside’s dolphins surfing azure breakers, southern-right whales nursing calves in kelp-fringed coves. It also looks like an engineer’s cost nightmare. The closest 400 kV line sits 65 km inland across folding mountain roads; the nearest usable port is 85 km away at Hermanus, meaning 8 m-long steam-generator casings would have to be barged in and then trucked over Sir Lowry’s Pass. Sustainable groundwater yield is 1.2 megalitres a day, but a twin-unit station needs 40 megalitres for once-through cooling. And the coastline is branded by tourism boards as “Where the Mountains Meet the Sea” - a slogan that translates, in EIA-speak, into “irreversible regional-scale scenic value loss.”

The Scoping Report is blunt: Thyspunt’s vistas are already “compromised” by 240 wind turbines erected since 2018, whereas Bantamsklip’s seascape remains “intact.” In cost-benefit terms, the choice was numerical, not emotional. Estate agents in the Hemel-en-Aarde valley report house prices easing 6 % since the downgrade; in St Francis Bay, rentals have doubled in two years, mirroring the 2010 World Cup spike as French and Korean engineers begin short-term leases.

5. Billions, jobs and the comment wars ahead

Eskom’s latest corporate plan sets aside R2.8 billion for “nuclear preparation,” but the utility’s going-concern warning states the real money - R350–420 billion - must come from a sovereign guarantee or equity partner. Paris-based EDF dangles two EPR-1750 units with 25 % local content; Rosatom markets a VVER-1300 cluster bundled with desalination; South Korea’s KEPCO pushes the APR-1400, arguing compatibility with Koeberg’s French software. All three imply debt equal to 2.5 % of GDP, a slice Treasury refuses to house inside the existing R469 billion Eskom bailout for fear of Moody’s downgrade.

Construction could, at peak, absorb 15 000 on-site workers and 45 000 indirect, but Kouga’s unemployment already tops 42 %. Modellers from Nelson Mandela University predict an inflow of 28 000 job-seekers, swelling informal settlements from nine to seventeen between Oyster Bay and Humansdorp. Public hearings - set for 20–24 April across four halls - have doubled security and drafted clergy as “peace marshals,” memories still fresh of the 2014 shale-gas meeting that closed the N2 with 800 protesting anglers.

Beyond the comment box, the route to first kilowatt is a gantlet: Ministerial sign-off by July 2025, specialist studies through 2026, a Draft EIA in early 2027 and a Record of Decision by late 2027 - provided SAHRA’s heritage boundary is settled, Treasury’s debt ceiling holds and no climate-litigation grenade lands in the Constitutional Court. If all stars align, the first reactor could send electrons to the Poseidon–Gourikwa–Beta 765 kV loop by 2040, turning Thyspunt from a windswept dunefield into the economic pivot of the Southern Cape. Until then, every public submission, every heritage permit and every fiscal comma will be fought over line-by-line in the comments section of a 776-page PDF released on an otherwise ordinary Tuesday in March.

Why was Thyspunt chosen over Bantamsklip for South Africa's 5200 MW nuclear power plant?

Thyspunt was chosen primarily due to its easier grid connection and lower impact on tourism compared to Bantamsklip. While Bantamsklip boasts scenic beauty, its remote location and environmental sensitivities would have made construction much more difficult and costly.

What is the significance of the 5200 MW nuclear power plant for South Africa?

A 5200 MW nuclear power plant is a massive undertaking, equivalent to adding an "extra Gauteng" to South Africa's power grid. It could generate 41 TWh annually, significantly reducing reliance on diesel-fired power and avoiding 18 million tonnes of CO₂-equivalent emissions, comparable to taking all cars in Cape Town off the road. This project has the potential to reshape the country's energy landscape.

What makes Thyspunt a "plug-and-play" location for the power plant?

Thyspunt is considered a "plug-and-play" location due to several factors. Eskom already owns 90% of the land, and a 400 kV transmission corridor with ample capacity passes nearby, requiring no new servitudes. This avoids the common and lengthy land-owner disputes associated with new power line infrastructure in South Africa.

What are the environmental and historical concerns at Thyspunt?

Despite its logistical advantages, Thyspunt is not without significant concerns. The site features wandering dunes that threaten National Freshwater Ecosystem Priority Areas, and the nearshore area is a critical spawning ground for the commercially endangered seventy-four seabream. Furthermore, Middle Stone Age hearths, crucial to the "Out-of-Africa-2" theory, are located beneath the sands. In 2025, the entire dunefield was declared a Provisional Grade I Cultural Landscape, imposing strict heritage protection.

Why was Bantamsklip ultimately deemed unsuitable despite its appeal?

Bantamsklip, while visually stunning, presented insurmountable engineering and cost challenges. It lacked close proximity to existing high-voltage power lines (65 km away), had no suitable nearby port for transporting large components (85 km to Hermanus), and had insufficient sustainable groundwater for the plant's cooling needs. Additionally, its high scenic value meant construction would have resulted in "irreversible regional-scale scenic value loss," conflicting with its tourism branding.

What are the financial and social implications of building the nuclear plant?

The project is estimated to cost R350–420 billion, requiring a sovereign guarantee or equity partner, which poses a significant strain on South Africa's national debt and could impact its credit rating. Socially, while it could create up to 15,000 on-site jobs and 45,000 indirect jobs, it is also predicted to attract 28,000 job-seekers, potentially swelling informal settlements and increasing social pressures in the region. The project faces a long and complex approval process, with many potential hurdles that could delay its completion until 2040.
