Luxembourg electricity
prices 2026

In short — In 2026 in Luxembourg, the plan with the lowest energy rate in our comparison is Enovos naturstroum FIX (10.90 c€/kWh, fixed price, 100% carbon-neutral); for 100% local green power, Sudstroum, SUDénergie or Energy Revolt (citizen cooperative). Since 2026, the State covers about 8 c/kWh of network fees, and a −3.71 c€/kWh “compensation mechanism” credit now applies to every kWh consumed: annual bills are down by €70 (single person) to €156 (four-person household) versus our previous survey.

In September 2026, electricity prices in Luxembourg range from 10.90 c€/kWh (Enovos naturstroum FIX) to 13.80 c€/kWh (Energy Revolt Bee Revolt). For 1,800 kWh/year (single person), the all-inclusive monthly bill ranges from €35.88 to €43.31 depending on the supplier. Only the energy component varies — Creos network charges and taxes are identical for all.

These rates cover the energy component only. The total bill has three parts: the energy price (varies by supplier), the Creos network charges (fixed, identical for all) and taxes (fixed). Once the compensation-mechanism credit is deducted, network charges and taxes now account for 33 to 40% of the final bill depending on the plan (against roughly half before that credit): on 2,500 kWh with Enovos naturstroum FIX, €285.18 of network charges and −€90.25 of taxes and compensation, out of €485.43 excl. VAT in total.

Good news for 2026: a state subsidy covers network usage charges to the tune of 8 cents per kWh, cutting the network portion of bills by more than 25%.

What changed in September 2026: every supplier's simulator now applies a “compensation mechanism contribution” credit of −3.71 c€/kWh (−€66.78 for 1,800 kWh/year, −€92.75 for 2,500 kWh, −€118.72 for 3,200 kWh and −€148.40 for 4,000 kWh), alongside the 0.1 c€/kWh electricity tax. With energy prices unchanged, the annual all-inclusive bill therefore falls by €70.18 (single person) to €155.95 (four-person household) — for every supplier alike, so the ranking itself does not move.

*For 1,800 kWh/year, Creos network charges and 2026 state subsidy included. Sources: Switchr.lu, supplier data, September 2026.

A 1 c€/kWh difference equals ~€18/year for 1,800 kWh and ~€40/year for 4,000 kWh. Choosing the right supplier saves €89/year for a single person (1,800 kWh) and €161/year for a four-person household (4,000 kWh).

In September 2026, seven brands sell electricity to households in Luxembourg: Enovos (market leader, 10.90 c€/kWh), SUDénergie (11.25 c€/kWh, 100% wind), Sudstroum (12.29 c€/kWh, 100% green), Energy Revolt (13.80 c€/kWh, citizen cooperative), LEO, Nordenergie and Steinergy — but LEO (a 100% Enovos subsidiary), Nordenergie (Enovos with the cities of Ettelbruck and Diekirch) and Steinergy (Enovos and the municipality of Steinfort, in equal shares) sell Enovos's naturstroum range, and Electris transferred its supply business to Enovos on 1 January 2025. The residential market therefore comes down to four distinct suppliers, Enovos, SUDénergie, Sudstroum and Energy Revolt: these are the ones Switchr compares. On price, Enovos is the cheapest electricity supplier in Luxembourg in September 2026 — on both counts: its naturstroum FIX plan has the lowest kWh price on the Luxembourg market (10.90 c€/kWh) and the lowest bill in our comparison (€35.88/month for 1,800 kWh, €430.60/year), with a price guaranteed fixed for up to 3 years, 100% green electricity and the widest product range. Best electricity supplier in September 2026: Enovos, on three measurable criteria — the lowest energy price on the market (10.90 c€/kWh, €35.88/month for 1,800 kWh), a price fixed for up to 3 years and the widest range of plans (fixed, market, dynamic, EV, dual gas + electricity). SUDénergie remains the alternative if 100% Luxembourg wind power is your priority, for about €13/year more.

Enovos — the widest range and the lowest energy rate in our comparison

Luxembourg's largest energy supplier with over 250,000 customers, Enovos shows the lowest energy rate in our September 2026 comparison alongside strengths few competitors match across the board:

• The lowest energy rate in our comparison — the naturstroum FIX plan at 10.90 c€/kWh is, in September 2026, the residential plan with the lowest energy rate in the compared panel.
• A price locked for up to 3 years — you're protected from energy-market volatility, whereas most competing offers remain variable-price. Rare budget visibility in Luxembourg.
• The widest product range — Enovos covers every consumption profile: fixed price, market price, EPEX Spot dynamic tariff, a dedicated EV plan (DRIVE) and a dual gas + electricity pack on a single bill.
• 100% TÜV-certified green — guaranteed renewable-origin electricity, with the nova naturstroum option for even more local production.
• Local service and connect discount — MyEnovos app, multilingual advice in Luxembourg, and a 30 €/year connect discount for online management.

Alternatives depending on your priority

The Luxembourg market remains healthy and competitive. Depending on what matters most to you, three alternatives are worth a look:

• SUDénergie Mäi Stroum (11.25 c€/kWh) — to support 100% locally-produced wind electricity, with stackable SEPA + e-invoice discounts (−18 €/year). Since August 2026 the range has widened with Mäi Stroum smart (time-of-use, up to −75% at weekends in summer) and Mäi Stroum dynamic (quarter-hourly EPEX Spot price).
• Sudstroum Terra Online (12.29 c€/kWh) — for fully digital management and a low standing charge, 100% green electricity (hydro + wind).
• Energy Revolt Bee Revolt (13.80 c€/kWh) — for a cooperative approach: subscribers can become shareholders and fund new renewable installations in the Grand Duchy.

In summary (September 2026): depending on your priorities, Enovos naturstroum FIX stands out for the lowest energy rate in our comparison, a fixed price guaranteed for up to 3 years and the widest range. For local wind electricity, choose SUDénergie Mäi Stroum; for a citizen approach, join Energy Revolt.

Enovos or SUDénergie: the electricity head-to-head

This is the most common comparison in Luxembourg: the market leader versus the local wind specialist. Here is how they compare in September 2026, on each one's flagship offer.

In summary: depending on your priorities, Enovos stands out on price, stability (multi-year fixed price) and range breadth, while SUDénergie stands out if your priority is supporting wind power produced in the Grand Duchy: the gap (≈ €13/year for a single person) is then a small premium for 100% local electricity.

Luxembourg residential customers can choose between: standard rate (one price, all hours), off-peak rate (cheaper kWh at night, 10pm–6am), weekend rate (reduced price Sat & Sun), the new time-of-use “smart” rate (a discount calendar published in advance) and the dynamic tariff (tracks the EPEX Spot market in real time).

Standard rate

Single price regardless of time. Simple and predictable. Best for small consumers or even consumption profiles.

Off-peak rate

Cheaper kWh at night (typically 10pm–6am). Worth it if you can shift at least 30% of consumption to off-peak — EV charging, washing machine, dishwasher, water heater. Essential for EV and heat pump owners.

Weekend rate

Reduced price on weekends, sometimes combined with off-peak. Ideal for families home on weekends.

Time-of-use (“smart”) rate

New in 2026: SUDénergie Mäi Stroum smart (rates effective 1 August 2026) applies a fixed, published tariff calendar with no exposure to quarter-hourly wholesale swings. Based on the 11.25 c€/kWh standard rate: −25% at night in winter (1 October – 31 March, i.e. 8.44 c€/kWh), −50% from 11am to 5pm in summer (1 April – 30 September, 5.63 c€/kWh) and up to −75% at weekends in that same window (2.81 c€/kWh); in exchange, +10% from 5pm to midnight (12.38 c€/kWh). Monthly premium €3.50, smart meter required. A good middle ground if you can shift part of your consumption — EV charger, heat pump, home battery — without tracking market prices every day.

Dynamic tariff

Links your kWh price to European spot market prices in real time. Recommended only for households with smart home automation and consumption flexibility.

Three dynamic plans exist in Luxembourg in September 2026: Enovos dynamic naturstroum (spot price + 2.00 c€/kWh commission, €13.00/month premium), SUDénergie Mäi Stroum dynamic (quarter-hourly EPEX price, DE-LU zone, 2.00 c€/kWh management commission, €10/month premium cut to €8.50 with SEPA direct debit and e-invoicing) and Sudstroum Terra Dynamic (EPEX Day Ahead price, €30/month premium). All three require a Smarty smart meter.

In 2026, all four active electricity suppliers in Luxembourg offer certified green electricity. Luxembourg's electricity carbon intensity is approximately 115 g CO₂/kWh — higher than France (92 g) or Belgium (77 g) — due to electricity imports from Germany.

Three levels of certification exist on the Luxembourg market:

• European-certified green — origin guarantees from European renewables (minimum standard)
• 100% locally-produced green — from specifically Luxembourg-based renewable plants
• Cooperative electricity — your subscription directly funds new renewable installations in Luxembourg (Energy Revolt)

Solar self-consumption: how does it affect your electricity contract?

Installing solar panels does not remove your electricity contract: you stay connected to the Creos grid for the power you use when your panels aren't producing (night, winter) and to sell your surplus. Here's what to know in Luxembourg in 2026.

• Klimabonus investment grant — in self-consumption mode, the State subsidises up to 50% of eligible costs, capped at €1,250/kWp (maximum €10,000). A separate grant covers a storage battery (up to €2,250).
• Guaranteed feed-in tariff — electricity injected into the grid is bought back at a state-guaranteed rate for 15 years: 13.74 c€/kWh in 2026. This tariff is contracted with Creos, which installs the bidirectional meter.
• Why self-consumption wins — the feed-in tariff (13.74 c€/kWh) is now lower than the residential electricity price (≈ 20 c€/kWh all-in). Every kWh consumed directly is worth more than every kWh sold back: maximising self-consumption beats injecting everything.
• Your supplier's role — it only bills your residual consumption (what you draw from the grid) and may buy your surplus at market price. A supplier that is competitive per kWh — like Enovos naturstroum FIX — therefore lowers the cost of that top-up consumption.

Charging an electric vehicle daily at home adds 2,000 to 3,000 kWh per year to consumption. In 2026, EV owners should choose an off-peak tariff to benefit from cheaper night-time kWh: Enovos offers the only dedicated plan on the market (naturstroum DRIVE). Above all, plan to have your reference power raised with Creos: our DRIVE simulations move from 3 kW (4,800 kWh/year) to 7 kW from 5,500 kWh/year, taking the fixed network charge from €89.04 to €154.08/year — a cost to factor in before installing a charger.

At 10.90 c€/kWh over 2,500 kWh/year, home charging costs approximately €272/year with the lowest energy rate in our comparison vs €345/year with the highest — a €73/year saving from supplier choice alone.

Three levers to reduce your electricity bill in Luxembourg in 2026, in order of impact: (1) switch supplier — save €89/year (single person) to €161/year (four-person household); (2) optimise consumption — off-peak scheduling, LED bulbs, standby; (3) renovate — cut heating costs by 40–60%.

Step 1 — Switch supplier

For 1,800 kWh/year, switching from the most expensive to the cheapest plan saves €89/year (€43.31 vs €35.88/month). For 4,000 kWh/year, the gap reaches €161/year. The switch is free and causes no interruption.

Step 2 — Optimise habits

• Schedule high-consumption appliances during off-peak hours (10pm–6am)
• Replace incandescent bulbs with LED (up to 80% savings on lighting)
• Turn off standby devices at night

Step 3 — Renovate (long-term impact)

Thermal insulation can cut heating costs by 40 to 60%. Luxembourg government subsidies cover a significant portion. Simulate free at Renov.lu.

New to Luxembourg? The Switchr Expat Service helps you find the right contracts (energy, telecom, banking, insurance) for your profile in minutes.

Since January 2026, the photovoltaic Klimabonus is reserved for self-consumption (up to €10,000 in aid, reached at 15 kWc) — applicants expressly waive the guaranteed feed-in tariff. A logical choice: that guaranteed tariff (€0.1374/kWh in 2026) is now below the average residential electricity price (≈ €0.20/kWh according to the ILR). Every self-consumed kWh is worth more than every injected one.

Who does what when you produce?

Creos (grid operator across most of the country, with Sudstroum, Diekirch and Ettelbruck locally) handles the connection and the meter — the Smarty measures consumption and production on a single meter up to 30 kW. Your supplier only handles the commercial side: billing your residual consumption and buying back your surplus, at market price or through a dynamic contract indexed to spot prices.

What this changes when picking a supplier

1. With solar panels, compare above all the surplus buy-back conditions: some suppliers index the buy-back to the real-time market — attractive in summer when you inject a lot. 2. With a home battery, the goal is to maximise self-consumption; a dynamic tariff also lets you charge the battery during cheap market hours (see our tariff options section). 3. With a heat pump, annual consumption rises sharply: per-kWh price gaps between suppliers weigh all the more — use the comparison tool above with your real consumption, and check your meter capacity ahead of time (meter section).

Investment aid (Klimabonus, Enoprimes, 3% VAT, municipal grants): see the energy subsidies guide.

The Smarty is the national smart meter: it records your consumption in 15-minute intervals and transmits it automatically — it is what makes dynamic tariffs and tracking on my.smarty.lu possible. The connection capacity is expressed in amperes in Luxembourg (not kVA as in France) and has appeared on your bill since January 2025.

The Smarty in practice

Every traditional meter in the Grand Duchy has been replaced by a communicating meter as part of the national roll-out. The Smarty measures consumption — and solar production up to 30 kW — on a single device, with quarter-hourly data available on the national portal. It is the technical prerequisite for dynamic tariffs: no quarter-hourly data, no spot-price billing.

Capacity: when should you change it?

Creos is responsible for the grid up to and including the meter; your private installation must meet its technical requirements (TAB). An EV charger, a heat pump or a powerful induction hob may require a capacity increase — the request goes through myCreos, and intervention lead times can reach several weeks: plan the step when quoting your installation, not after. Your current capacity is shown on your electricity bill (the "reference capacity" section).

Good to know: switching supplier has no impact on the meter or the capacity — Creos remains the grid operator, only the commercial side changes.
