Telefonica Germany Builds Energy Self-Sufficient 5G Radio Tower

O2 Telefonica (Telefonica Germany) said it has set up its first energy-self-sufficient radio tower in the town of Kirtorf in the state of Hesse, effectively closing one of the last white spots. According to Telefonica, the 50-meter-high mast, equipped with modern 5G technology, is powered by solar cells and a highly efficient fuel cell, providing uninterrupted service to the users in the region.

Self-Sufficient Radio Tower

Located amidst agricultural and forestry land, the new mobile site location in Kirtorf covers a dead spot, enabling residents to use Telefonica’s 2G, 4G and 5G networks. Traditional power supply options were deemed impractical due to high costs, prompting O2 Telefonica to develop a solution for climate-friendly energy generation.

Photovoltaic modules installed alongside the radio tower serve as the primary energy source for the system. Electricity generated during the day is stored in lithium batteries to ensure continuous operation. Additionally, on sunny days, a biomethanol fuel cell supplements the power supply. Intelligent software seamlessly manages energy sources, optimizing efficiency and reliability. Telefonica Germany noted that since the electricity is generated on-site, the new concept saves more than 13,000 kilowatt-hours per year compared to a mobile phone tower operated with conventional electricity.
