About this episode

The episode discusses the role of solar energy in enhancing energy security and stabilizing power systems, featuring insights from experts Timothy Shen and Dr. Rethabile Melamu.

Energy security is back at the top of the global agenda and new ways to secure supply are evolving fast. In this episode of The smarter E Podcast, we explore how solar is moving beyond generation to play a critical role in stabilizing power systems and delivering energy security. First, Wood Mackenzie analyst Timothy Shen breaks down the rapid evolution of solar inverters – and how they are well equipped to meet the challenges of today’s changing power mix. Once seen as passive components, today’s advanced inverters can actively support the grid managing voltage, frequency, and providing reactive power in real time. As the energy transition accelerates, these capabilities are becoming essential to keeping power systems reliable, especially during disruptions. We also examine what recent grid failures reveal about the gap between older infrastructure and newer, more resilient technologies, and why the latest generation of inverters could help prevent future blackouts. In the second half of the episode, Dr Rethabile Melamu from the South African Photovoltaic Industry Association shares insights from Africa’s rapidly accelerating solar market. With hundreds of millions still lacking…
