Luxembourg Electricity Tariff API

How a household electricity price is built in Luxembourg

Luxembourg has no wholesale exchange or bidding zone of its own — it shares Germany’s day-ahead price zone entirely — and retail supply has been fully liberalized since 2007, though switching remains rare and the incumbent still supplies the great majority of homes. Distribution is drawn purely by commune, with one operator covering all but three small municipal networks, and every operator’s network tariff is set to the same nationwide price list rather than varying by company. The state has been directly subsidising both the network charge and the renewables levy since 2026.

What a household bill is made of

1. 1

   Energy

   There is no Luxembourgish power exchange: because the cross-border links to Germany carry no congestion, the country is treated as part of the German day-ahead price zone, and every product references that price. Static products fix the energy rate for a contract term, usually sold in monthly vintages with a multi-year price guarantee; dynamic products, new to the residential market only since 2024, pass the hourly day-ahead price through with a margin and a monthly fee.

2. 2

   Network charges

   Approved annually by the regulator for each network operator, but the approved price list is identical across all of them — a household pays the same network tariff no matter which of the country’s distribution operators serves its commune. The structure is built on a rolling reference power recomputed monthly from the household’s own recent consumption: a monthly fixed charge that scales with it, a volumetric charge on the whole volume, and a supplement on volume drawn above the reference. Since 2026 the state directly funds part of the allowed network revenue, cutting the household charge for at least three years.

3. 3

   Taxes and levies

   Two statutory items, both collected by the network operator. A small, flat electricity excise applies per category of annual consumption, unchanged in real terms across recent years. A separate contribution funds the guaranteed purchase of renewable and high-efficiency-cogeneration electricity — and has been negative, a credit rather than a charge, for years running, first because the mechanism over-recovered and increasingly because the state now funds it directly as a household subsidy. There is no concession fee and no municipal electricity tax.

4. 4

   VAT

   8%, the reduced rate — electricity has never been at the 17% standard rate — applied to the whole bill including the standing charge, with no domestic/non-domestic split.

Regulation shaping the price

• The Institut Luxembourgeois de Régulation (ILR) accepts each operator’s network tariff by annual decision, sets the smallest customer band’s renewables-mechanism contribution by its own regulation, approves the conditions and prices of the statutory default supply, and runs the national price-comparison portal.
• A statutory default supply applies to anyone who has not chosen a supplier, typically after a move — one default supplier per distribution network, which since 2023 keeps the customer even after the default period ends rather than handing them to a separate last-resort supplier.
• Household solar is remunerated by the network operator directly under a purchase-price schedule guaranteed for fifteen years from first injection: the published schedule for new installations is revised annually, but each household’s own rate, once set, holds for the full guarantee. Larger plants sell on the market with the operator topping up to a statutory reference price. Collective self-consumption and energy communities are established alternatives to exporting.
