In accordance with the law of 7 August 2012 that transposes the European Energy Efficiency Directive into Luxembourg legislation, all the gas and electricity meters must be changed in the country, independently of the network operator. By the year 2020, Creos will thus install 300,000 smart meters that record detailed information on the consumption and production of energy in the entire territory of the Grand Duchy of Luxembourg, including 250,000 electricity meters and 50,000 gas meters. The installation of these new electricity and gas meters – called Smarty – in Luxembourg homes will allow the creation of networks with real intelligence: smart grids. These smart grids are capable of monitoring decentralised electricity production (like wind turbines and photovoltaic panels), regulating the variations of the feeds into the distribution networks with greater precision and managing the demand peaks linked with the charging of electric vehicles more effectively. The law from 7 August 2012 also demands that the metering system must be able to receive water and heating.
