In 2015, the country's total energy consumption increased slightly compared to 2014, according to the Luxembourg Institute of Regulation (ILR).

Luxembourg produces just 20.5% of its own national energy consumption by domestic production and 6.7% with renewable energies (hydroelectric, wind, biogas, photovoltaic, biomass, waste incineration); the balance is covered by net imports up to 79.5%.

On the retail electricity market, ten electricity companies were active in Luxembourg las year: 7 in the residential market and 10 in the non-residential market (to professional customers, e.g. industrial sites, administrations, etc.).

The transmission of electrical energy through the electrical system takes place through transport networks and distribution networks. Extremely high voltage transmission networks transport energy over long distances and between countries, while high, medium and low voltage distribution networks serve to connect consumers and producers to the electricity system. In Luxembourg, the transmission network is operated by the transmission system operator (GRT) Creos Luxembourg S.A., which is also a distribution system operator (GRD) over most of the territory of Luxembourg. Four municipalities each have their own distribution system operator. Also an industrial network manager (GRI) that transports electricity to industrial sites in the south of the country from the Belgian and French transport networks.

Given the low capacity of power stations connected to the Luxembourg networks, Luxembourg continues to import the bulk of its electricity, mainly from Germany (4,248 GWh in 2015), as the transmission network is interconnected with the German transmission network, also France (1,054 GWh) and Belgium (256 GWh), totalling 5,557 GWh, with the total power consumed across the Grand Duchy in 2015 being 6,371 GWh.

Consumption:

- Residential: 914 GWh (14.35%)
- Professional: 1,607 GWh (25.24%)
- Industrial: 3,847 GWh (60.41%)

With Enovos providing 74.19% of energy to the residential sector, 58.18% of energy to the professional sector and 48.93% of enenergy to the inducstrial sector, it is by far the largest supplier in Luxembourg, with LEO second in the residential sector (13.90%), LEO second in the professional sector (27.62%) and ArcelorMittal Energy second in the industrial sector (40.47%).

In 2015, Luxembourg covered 20.5% of national consumption by domestic production and 6.7% by production based on renewable energy sources (hydroelectric, wind, biogas, photovoltaic, biomass, waste incineration).
