Huawei's Smart Substation: A Leap Towards Intelligent Energy Systems

On May 20, 2026, Huawei hosted an electric power summit in Cape Town, South Africa, as part of the Enlit Africa 2026 conference, a pivotal gathering for the energy and water sectors on the continent. This year's theme, "Building Future Energy Systems: Initiating Rapid Growth Through Digital Intelligence," brought together industry leaders and partners, including Eskom from South Africa, BPA from Ghana, Transmission Company of Nigeria (TCN), and the International Council on Large Electric Systems (CIGRE).

During the summit, Huawei, in collaboration with its partners, unveiled an innovative smart substation solution tailored for Sub-Saharan Africa. This initiative aims to accelerate the region's digital transformation within its energy sector, leveraging cutting-edge technologies to enhance operational efficiency and reliability.

Wang Guoyu, Vice President of Huawei's Digital Power Division, delivered a keynote address titled "Progress in Every Intelligence: Empowering Future Energy Systems." He emphasized that a consumer-driven model oriented towards the future is now becoming a new paradigm for energy transformation. According to Wang, the energy system is at a critical juncture, transitioning towards greater intelligence that redefines its core infrastructure through enhanced communication, digitalization, and artificial intelligence (AI).

He further highlighted that AI and digital technologies are pivotal in transforming the entire energy sector value chain, from generation and transmission to distribution. Huawei aims to combine its advanced AI capabilities with reliable communication technologies to support African energy companies in elevating their operational efficiency and intelligence levels.

Collaborating with CIGRE and Zhuhai Unitech Power Technology Co., Ltd., Huawei presented its smart substation solution, reinforcing its commitment to modernize smart substations across the continent through strategic partnerships. This new solution integrates smart video, AI algorithms, and secure wireless networks that replace four critical manual operations with intelligent automated systems—monitoring, control, meter reading, and analysis.

A representative from an African energy company noted, "This innovative solution allows operations and maintenance staff to remotely monitor the entire station. The inspection time has decreased from days to just minutes, and operational and maintenance labor costs have been reduced by 70%." This transformation not only improves efficiency but also paves the way for a proactive rather than a reactive maintenance approach in energy management.

Huawei, CIGRE, and the 450 MHz Alliance held a roundtable discussion post-summit focusing on private wireless networks for energy telecommunication systems. Gösta Kallner, Executive Chairman of the 450 MHz Alliance, emphasized how private wireless networks built on the 450 MHz spectrum have become a cornerstone for ensuring reliable and sustainable network operations due to their extensive coverage and diverse ecosystem.

A CIGRE representative added that, from an international standardization perspective, a unified technical framework and the sharing of global best practices are essential for accelerating the digital transformation of electrical networks. The participants collectively agreed that establishing a ubiquitous, secure, and efficient foundation for energy communication is crucial for supporting new energy systems and achieving sustainable energy development in Africa.
