Creos installs and manages the meters, processes the customer consumption data, invoices the network access charges and monitors the suppliers' movements and changes.

[15] The majority of the electric current in the Grand Duchy of Luxembourg comes from Germany via two double high-voltage 220,000 volt (220 kV) lines that are connected to the German network.

[16] The interconnection with the Belgian electricity market has become operational with the commissioning of a phase shifting transformer (PST) at the Schifflange Centre in October 2017,[17] and around 15% of the energy fed into the network is produced locally (biogas, cogeneration, wind turbines, hydroelectricity and photovoltaics)[18] The electricity is transmitted to the six transformer stations (Flebour, Roost, Itzig/Blooren, Heisdorf, Bertange and Schifflange) where the voltage is reduced from 220 to 65 kV before being distributed to industries and large municipal distribution networks.

[24] Balansys, the joint venture between Creos and its Belgian counterpart Fluxys, is the balancing operator in the Belux zone from 1 June 2020.

[25] Creos has four regional centres, which are dedicated to building, operating, maintaining and repairing the electricity and natural gas networks.

Dispatching for electricity and natural gas together with the monitoring rooms for remote network control and management are installed at the Creos facility in Bettembourg since 2020.

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 across the entire national territory, independently of the network operator.

The installation of these new electricity and gas meters – called Smarty – in Luxembourg homes will enable the creation of networks with built-in real intelligence: smart grids.

Each station is equipped with two charging points, which means that the network, called Chargy, will eventually consist of 1,600 parking spaces dedicated to electric mobility.

Creos handled the deployment, operation and maintenance of the public charging infrastructure on its distribution network, totalling nearly 700 out of the planned 800 stations.

It brings together Creos, other distribution networks and suppliers in collaboration with the Ministry of Energy and the Luxembourg Institute for Regulation (ILR).
