Message from the Chief Executive
A new chapter for HVT.
For more than thirty years HVT has built, maintained and protected the high voltage infrastructure that keeps Southern Africa’s power flowing. Our people have installed equipment at every voltage level up to 765 kV, worked in fourteen African countries and earned the trust of Eskom, regional utilities and some of the continent’s largest mining and industrial companies.
HVT has now entered a new chapter under new ownership. Our name, our teams, our contracts and our commitment to our customers continue unchanged. What we add is sharper governance, stronger investment in people and systems, and a clear focus on the next decade of grid growth: transmission expansion, substation renewal, renewable energy integration and dependable maintenance services.
Our promise is simple. We take on tough technical problems, we deliver them safely, and we stand behind our work.
