Charging planner · LuxembourgCharge your electric car for less in Luxembourg
Choose your car, the distance or the amount of energy and the charging power below: the planner finds the cheapest quarter-hours in Luxembourg and shows what the charge costs.
Charging times:
Charging time: –
At most 17 kWh fit into this window. Choose a higher charging power or a later departure.
Price per quarter-hour in the chosen window; charging times are highlighted. Costs at the estimated final price: wholesale price, network charges, taxes, levies and a sample supplier margin.
Tomorrow's prices are published in the early afternoon. Until then the planner only runs to midnight.
Consumption: WLTP figure from EU type-approval data (median of the cars newly registered in 2025, measured at the socket). Real-world use, especially in winter, is often 10–30% higher.
Charging at home in Luxembourg: the last 30 days
In the last 30 days (21 Sept – 20 Oct), the four cheapest hours in a row on an average day were 12:00–16:00, at €0.138/kWh on average including network charges, taxes and levies.
Charging for 100 km (17 kWh) cost €2.35 in those hours and €4.89 between 17:00 and 21:00. Over 15,000 km a year, that is a difference of about €380. The wholesale price was below zero for 4.5 hours in this period.
| Price per kWh | 100 km (17 kWh) | 15,000 km a year | |
|---|---|---|---|
| Cheapest 4 hours (12:00–16:00) | €0.138/kWh | €2.35 | €351 |
| Night (00:00–06:00) | €0.200/kWh | €3.39 | €508 |
| Evening (17:00–21:00) | €0.287/kWh | €4.89 | €732 |
| Average of all hours | €0.215/kWh | €3.66 | €549 |
Costs at the estimated final price: wholesale price, network charges, taxes, levies and a sample supplier margin.
When is charging cheapest?
On a dynamic tariff you pay the wholesale price for every quarter-hour, plus the fixed components. Electricity is usually cheapest at night and around midday on sunny days, and dearest in the early evening, when demand peaks and solar output fades. A car plugged in overnight often needs only three or four hours – the planner puts them in the cheapest part of the night.
Smart charging means the wallbox or the car only charges in the cheapest quarter-hours, with pauses in between if needed. Many wallboxes and car apps do this automatically with dynamic tariffs. If you only have a start timer, choose “Timer”: the planner then finds the cheapest continuous block.
How much electricity does my car need?
Consumption figures come from the official data on every electric car newly registered in Europe (WLTP, measured at the socket, so charging losses are included). Small cars need about 14–15 kWh per 100 km, large SUVs more than 20 kWh. In winter, on motorways and on short trips with the heating on, consumption is higher – just enter your own figure.
Reference power and overrun charge
Since 2025, part of the network charge in Luxembourg depends on your reference power (3, 7, 12 kW and up), which the grid operator recalculates every month from your quarter-hour readings of the past twelve months. Every kWh drawn above that power carries an extra €0.0765 excluding VAT in 2026. If your reference power is 3 or 7 kW, charging at 11 kW pays it on everything above that level; a lower charging power spread over more hours avoids it. The planner leaves out this charge and the fixed monthly fee.
