About Suis — Our Story, Mission & Team | Sustainable Energy Consulting

Our Story

A Decade of Powering Change

Founded in 2016 in the heart of Durban, Suis was born from a simple conviction: South Africa's abundant natural resources -- sun, wind, and innovative spirit -- hold the key to a prosperous, sustainable future.

What began as a small consultancy led by Dr. Nomusa Dlamini has grown into one of the country's most trusted sustainable energy advisory firms. Over ten years, we have guided businesses, local governments, and industrial operators through every stage of the clean energy journey -- from feasibility studies and regulatory compliance to full-scale deployment and long-term optimisation.

Our vision extends beyond individual projects. We see a South Africa where reliable, affordable, and clean energy is the norm -- not the exception. Every engagement moves us one step closer to that reality.
