CIGRE and 450 MHz Alliance Release White Paper on Power Grid Private Wireless Networks to Advance Industry-Wide Adoption

At MWC 2026, the International Council on Large Electric Systems (CIGRE) and the 450 MHz Alliance jointly hosted the 2026 CIGRE SC D2 International Roundtable on Power Communications. The event brought together more than 100 industry leaders and experts from global standards bodies, industry alliances, grid operators, leading consultancies, equipment suppliers, and system integrators to explore the latest developments in power communications.

Release of the White Paper on Power Grid Private Wireless Networks

The white paper outlines a comprehensive framework for building power grid private wireless networks. It addresses six key areas: the strategic vision for future grid communications, core technical challenges, the unique advantages of private wireless networks, key criteria for technology selection, guidance for large-scale deployment, and a long-term outlook. Together, these elements provide a systematic blueprint for digitalization across the power industry.

Expert Panel Discussion on Power Communication Networks

The 450 MHz private wireless network has gained widespread industry recognition for its technical reliability and proven practical value, validated through numerous real-world deployments worldwide.

During a panel discussion on power communication networks chaired by Gösta Kallner, Chairman of the 450 MHz Alliance, representatives from Sweden Electric Power, Électricité de France (EDF), Capgemini Consulting, and the CIGRE D2 Working Group discussed three key aspects:

1. A comprehensive, secure, and reliable communication network with ubiquitous coverage is essential for the future development of power grids and stable power system operations.
2. Wireless private networks meet the connectivity and situational awareness requirements of modern power grids, effectively supporting their digital and intelligent transformation.
3. The 450 MHz spectrum offers clear advantages in accessibility, effectiveness, scalability, and long-term evolution, making it a leading option for power industry communications.

These discussions highlighted that the combined strengths of wireless private networks and the 450 MHz spectrum will become increasingly important in the development of future power systems.

The conclusions reached at the roundtable not only chart a clear course for the development of global power communication networks and the large-scale adoption of private wireless and 450 MHz technologies, but also provide an important platform for international cooperation and technological harmonization. Together with the white paper, the discussions lay the groundwork for continued innovation and standardization in power communications, supporting the digital, intelligent, and low-carbon transformation of the global energy sector.
