With the aim of building, connecting and empowering, Lesedi Nuclear Services has established itself as a leader in the energy sector

Lesedi Nuclear Services is an extremely innovative and dynamic engineering company that is dedicated to delivering the highest-quality engineering, procurement and construction (EPC) services to the energy sector. Originally evolved from Intens Engineering, founded in the 1980s, Lesedi has since diversified and successfully completed numerous key projects in the nuclear field, as well as in the company’s three major markets, namely power generation, mining, and oil and gas.

Headquartered in Cape Town, and with other offices (including in Centurion, Gauteng), Lesedi has a Level 3 B-BBEE accreditation and is made up of approximately 330 employees dedicated to clients across the continent. It also works with major players in the energy sector, as well as independent power producers.

The company’s core focus is on nuclear power, where it has established a strong track record of delivering complex and highly technical projects. Lesedi Nuclear Services has an extremely skilled team of engineers, project managers and technical specialists who bring together expertise from across the nuclear sector to deliver projects that meet the highest international standards.

Lesedi’s core services include feasibility studies, design, procurement, construction, commissioning and maintenance of nuclear power plants. The company has a strong commitment to safety, and all projects are delivered with a focus on minimising environmental impact and promoting sustainable development.

Within the mining sector, Lesedi has worked with some of the world’s leading mining companies to deliver complex projects. Its mining capabilities encompass a number of activities within the minerals processing and mining sectors. It services various ancillary plants that ensure mines operate functionally and efficiently. Through its network of world-class technology partners, Lesedi offers gas-cleaning and emissions-control plants for most energy technologies and provides systems for the capture of dust, tars, acid mists, SO2 and various other acidic gases and contaminants in the mining sector.

With experience in the oil and gas sector, Lesedi has delivered a range of projects, including pipeline construction, storage tank installations and offshore platform refurbishments. The company has a deep understanding of the unique challenges faced by the oil and gas industry, including safety, environmental and regulatory considerations.
