New Remote Power Supply Solution in Finland

New Remote Power Supply Solution in Finland

Finnish engineers achieved a revolutionary breakthrough in late 2025 by successfully testing a wireless electricity system that transmits power through the air without cables, plugs, or physical connections. Elisa in Finland is using cellular basestation backup batteries as an AI-enabled virtual power station. Using the Radio Access Network (RAN) to run a Virtual Power Plant could save telecoms operators around 50% of their current. At the heart of Finland's wireless power system is the concept of using electromagnetic fields to carry electricity over a distance. Research teams from the University of Helsinki, University of Oulu, and Aalto University. With the launch of its new smart charging service, EV drivers in Finland can now participate in grid.
