Smart meters use state-of-the-art technology in order to measure the energy (electricity, natural gas, urban heat) or water consumption of each dwelling at regular intervals. The meter records the values and transmits this data via the existing electricity network to a central system, which collects the data from the meters for the whole country and transmits it to the network operator.
The central data collection and management system is managed and operated by the Luxmetering economic interest group, which was created in 2012 by the country's seven electricity and gas network operators: Creos Luxembourg, City of Ettelbruck, City of Diekirch, Electris, City of Dudelange, Sudstroum and Sudgaz.
It should be noted that the network operator builds and operates the electricity or natural gas networks, and that the supplier buys and resells energy and associated services.
