new avenues that we have to explore.” Rather than simply supplying what a customer requests, TMC Transformers prefers to examine the application in detail to identify potentially better alternatives. “We therefore look at all the electrical parameters and alternative materials and check the customer’s approach with our own systems analysis and simulations, to see what improvements can be achieved,” he says. “Simulations are very useful in testing and confirming all the electrical and mechanical variables before we decide on a final solution with the customer.” Claassen says this approach aligns closely with the way Trafo Power Solutions works, drawing on deep technical expertise to deliver the most e§ective and robust outcome. “Our customers come to us to procure a transformer or larger electrical power system, but they also get the benefit of our engineering insights,” he says. “We can help to finetune a design, consider better alternatives or in some cases pick up a blind spot that could create challenges for them later.” Advanced soware support Another advantage of the Trafo Power Solutions-TMC partnership is access to TMC’s advanced so¤ware tools including finite element analysis and thermo-dynamic simulations. Claassen says this supports technological advances and market confidence. “With its strong foundation of engineering expertise, TMC can scientifically verify the designs before the manufacturing stage is initiated,” he says.
Through their partnership Trafo Power Solutions and TMC Transformers continue to drive innovation, pushing the frontiers of what dry-type transformer technology can achieve. By combining deep engineering expertise, advanced simulation tools and a commitment to solving real-world challenges, the two companies are expanding the scope of dry-type transformer applications and setting new benchmarks for safety, reliability and performance across a range of demanding industries. “As the energy landscape evolves and industrial demands intensify, our collaborative approach ensures our customers receive a future-ready solution tailored to their needs,” Claassen concludes.

tions with confidence. At its core, Energypro streamlines the allocation of energy across the grid, ensuring supply and de- mand are matched accurately and transparently, and offering full visibility into performance and settlement. How does it work? Consider a mining company weighing up two different offers, each with its own contract length, structure, and level of risk. On the surface, the numbers are hard to compare, and the risk in choosing the wrong option is high. Energypro simplifies this by standardising the proposals, running the numbers against the mine’s actual consumption profile, and showing the true cost and risk implications – all done within minutes rather than weeks. Why is it needed? South Africa’s energy market is steadily turning towards a clean energy mix, distributed energy resources, and a more open electricity market. Demand for energy has always been great, grid instability persists, and more private producers are enter- ing the market at pace. Without the right systems in place to support their decisions, buyers risk signing unfavourable deals, and suppliers can face costly delays. By introducing transpar- ency and trust, Energypro allows new projects to accelerate,
The need for reliable, affordable power is a day-to-day requirement – and growing. In South Africa, sellers of electricity – independent power producers (IPPs) and traders – are central in meeting this need, yet they face
a marketplace that is fragmented, complex, and often hard to navigate. Gerjo Hoffman, CEO of Open Access Energy, makes the point that to build a stronger energy future, we need solutions that simplify the process, reduce risk, and open the door to more transparent trading. Here he explains Energypro, a software suite developed by Open Access Energy and designed to make energy trading easier, smarter, and faster. Hoffman says, too often, IPPs spend weeks preparing proposals and cost estimates, and buyers struggle to
