What Lesedi Nuclear Services does

Lesedi Nuclear Services (Pty) Ltd is a South African privately-held engineering, procurement and construction (EPC) and EPCM contractor headquartered in Cape Town with a regional office in Centurion. The firm operates four divisions — Nuclear, Industrial, Oil Gas & Power, and Grid & Renewables — serving utilities, mining operators, industrial facilities, and government entities in South Africa and internationally. Its core market position is anchored by nearly three decades of embedded involvement at Eskom's Koeberg Nuclear Power Station, with over 200 completed modifications and an active presence across 29 international power stations in 8 countries including the USA, UK, France, Finland, Spain, Brazil, China, and Argentina. Notable clients include Eskom, Framatome, ENEC, Transnet National Ports Authority, EDF Renewables, TotalEnergies, Mozal Smelter, and Ardagh Group.

The company's underlying technology is its nuclear-grade Integrated Management System, certified to ISO 9001:2015, ISO 19443:2018, ISO 14001:2015, and ISO 45001, combined with AREVA RD-0034 Level 1 approval, NQA-1 compliance, and a documented 10-concept Safety Culture Enhancement Programme. Service delivery spans full-scope EPC, EPCM oversight, plant modifications, outage planning and execution, refuelling operations, electrostatic precipitator design, compressed air systems, and renewable energy EPC including solar PV installations. The Lesedi Skills Academy operates MERSETA and NAMB-accredited artisan programmes and an ECSA-aligned Engineer in Training pathway, providing an internal talent pipeline.

Commercially, Lesedi sells exclusively through direct enterprise engagement on a bespoke, project-based pricing model with multi-year contract cadences; no standard pricing tiers or self-serve channels exist. Revenue derives from EPC/EPCM contracts, maintenance and outage services, and training/skills development.

Scale indicators6 records

Recent moves6 records

Expansion highlights7 records

Direct peers

• Framatome: French nuclear reactor services and fuel company; both a partner and direct comparable given parallel capabilities in nuclear outage, refuelling, and modification services for operating reactors. Lesedi has executed Framatome-led outage work at Olkiluoto 3 and trained with Framatome in Lynchburg.

Broad incumbents

• Westinghouse Electric Company: Global nuclear OEM and EPC major offering reactor new-build, fuel, and services. Overlaps with Lesedi on plant modifications and outage services but operates at vastly greater scale and across the full reactor technology stack.
• AtkinsRéalis (formerly SNC-Lavalin): Canadian engineering services and nuclear services firm with deep CANDU reactor modification experience. Comparable on nuclear plant modifications, EPCM, and engineering services for operating reactors.
• Bechtel Corporation: US-based global EPC major with nuclear, power, mining, and renewables execution capability. Comparable as a multi-sector EPC competitor in South African and African infrastructure tenders though typically much larger project scale.
• Jacobs Solutions: US engineering, technical, and project services firm with a strong nuclear and critical infrastructure practice. Comparable on nuclear modifications, EPCM, and government/utility client delivery, though at much larger scale.
• Fluor Corporation: US-based global EPC major with nuclear, mining, and power delivery capability. Comparable as a horizontal EPC competitor for large-scale South African and African power and mining projects.
• Rosatom: Russian state nuclear corporation offering full reactor EPC, fuel, and services internationally. A potential new-build partner in Africa and a competitor for nuclear services work, operating at sovereign scale Lesedi cannot match.
• Worley Limited: Australian engineering services and project delivery firm with strong energy and resources focus. Comparable horizontal EPCM model across power, mining, and renewables, with energy-transition services that overlap Lesedi's Grid & Renewables division.

Regional players

• Murray & Roberts: South African engineering and construction group historically focused on mining, power, and oil & gas EPC. The most direct South African comparable to Lesedi's Industrial and Oil, Gas & Power divisions, though nuclear-specific capability is less central to its offering.
• Stefanutti Stocks: South African multi-disciplinary construction and engineering group operating across power, mining, and infrastructure. Comparable as a domestic EPC peer competing for similar Eskom, mining, and public-sector tenders.
