Mzesi Energy is a 100% black-owned energy solutions company based in Centurion, South Africa. Established in 2010, the company was formed after acquiring an independent consulting firm and identifying a critical skills shortage in the nuclear sector, alongside the growing demand for low-carbon energy solutions.
Since its inception, Mzesi Energy has positioned itself as a strategic contributor to South Africa’s energy landscape, working closely with government institutions and industry leaders to support national development objectives.
Mzesi Energy was founded at a time when South Africa was actively seeking to strengthen its energy security and expand its capacity in nuclear and low-carbon energy generation. Recognising this opportunity, the company built a strong foundation of technical excellence, regulatory insight, and strategic partnerships.
Over the years, Mzesi Energy has grown into a trusted name in the industry, notably becoming the Technical Support Organisation (TSO) for the National Nuclear Regulator (NNR) in 2014, providing critical technical and regulatory support on key national projects.
Through continuous innovation and commitment to excellence, the company has successfully delivered projects on time, within budget, and without compromising safety or quality standards.
