Optimising electrification solutions for Africa’s railway systems

Africa's railway systems have the potential to become more sustainable through the integration of high-voltage and low-voltage electrification solutions, alongside decentralised renewable energy sources. In a recent interview with Clemente Chukwuemeka, Executive Consultant at Grid Technology Delivery & Projects (GTDP), on CNBC Africa, key challenges and opportunities in this sector were discussed. One of the major challenges identified is the need for significant investment to upgrade existing utility networks to support railway electrification. This capital-intensive project requires not only the construction of new substations but also the installation of necessary equipment to supply the railway system with power. Despite these challenges, Africa has the capability and know-how to achieve this upgrade and boost the sustainability of its railway networks. By tapping into abundant renewable energy resources and incorporating smart grid technology, Africa can create a well-optimised and sustainable railway electrification system. This shift towards renewable energy solutions can also support Africa's overall energy transition. Collaborative efforts between government, private investors, and policy makers are essential to successfully implement these changes. With a long-term vision and strategic planning, Africa can lead the way in sustainable energy solutions for its railway networks, setting a precedent for the continent's energy transformation.
