Stand-alone base station for 5G mobile communications in Trollstigen, Norway

Project description

At the Trollstigen site in Norway, a stand-alone base station for 5G mobile communications went into operation in the fall of 2020. The electrical supply is provided exclusively using renewable energy sources: Solar, wind, hydrogen. The station is dimensioned in such a way that the solar and wind power is usually sufficient to operate the transmitting equipment. If, however, solar and wind energy are not sufficiently available, a fuel cell from the manufacturer Ballard Power Systems is used to supply the transmission technology with electricity. The energy storage system is a 125kWh Li-ion battery. The power supply concept, the converter technology and the higher-level control and regulation technology are products of ELTEK AS Nordic.
