Renewable electricity production in Luxembourg: the full picture 2026
Luxembourg imports the vast majority of the electricity it consumes — but its local renewable energy capacity is undergoing an unprecedented transformation. 1,443 GWh produced locally in 2024, 22.8% of national consumption covered, 975 MW of installed capacity: wind, solar, biomass, hydropower… This guide breaks down each technology, its key players, the ILR’s official figures, and the trajectory towards the NECP 2030 targets.

Luxembourg is a small country with no fossil resources, whose electricity consumption far exceeds its national production capacity. In 2026, over 70% of the electricity consumed in the country is imported, mainly from Germany. This import dependency is a historical constant — but it is gradually declining as the local renewable park expands.
Total national renewable production: 1,443 GWh (+14.5% vs 2023)
Share of national consumption: 22.8%
Total installed capacity all sources: 975 MW (+19.5% vs 2023)
Wind: 213.74 MW installed · Solar: 550 MW · Biomass: 75.06 MW
Wind production: 467 GWh (-5.6% due to weather conditions)
Solar production: 360 GWh (+22.4% — record growth)

A special case: the Vianden plant. The Vianden pumped-storage power plant (1,296 MW installed capacity) is often counted in Luxembourg’s production statistics. Its role is to store energy — pumping water to an upper reservoir using cheap imported electricity at night, then releasing it through turbines during peak demand periods. It is not a renewable energy source in the strict sense, but a crucial European grid balancing asset, operated by Société Électrique de l’Our (SEO) in partnership with RWE.
2. Wind energy: top national source, undergoing repowering
Wind energy is Luxembourg’s leading national electricity source. In 2024, wind turbines produced 467 GWh — 31% of national renewable production — despite a slight 5.6% decline due to less favourable wind conditions. Installed wind capacity stands at approximately 213.74 MW, mainly concentrated in the north of the country.
Soler S.A. (a joint venture between SEO and Enovos, founded in 2001) dominates the sector, operating 13 wind farms and representing around 70% of national wind capacity. The key strategy is repowering: replacing old turbines (0.5–1 MW) with next-generation models (~3 MW+), which allows halving the number of machines while doubling annual output. At the Windpower park in Rosport-Mompach, one new turbine now produces three times more energy than the four old ones it replaced.
The NECP 2030 wind target is 453 MW — more than double the current ~214 MW. Reaching this requires both accelerated repowering of existing parks and new authorisations for sites in the south, east and west of the country (previously less exploited, now viable with modern turbines that operate at lower wind speeds).
3. Solar PV: record growth in 2024
Solar PV is Luxembourg’s most dynamic renewable technology. In 2024, a record 156 MW of new installations were connected — twice the 77 MW installed in 2023. Total installed capacity reached 550 MW by end-2024 (up 40% in one year), and solar production hit 360 GWh (+22.4%). The number of active PV installations reached 22,610, of which 8,988 were new in 2024 alone (+66%).
2021: ~277 MW installed — 229 GWh produced
2023: 394 MW — 13,622 installations — 318 GWh
2024: 550 MW — 22,610 installations — 360 GWh
New installations in 2024 alone: 156 MW — an absolute record
NECP 2030 solar target: 1,236 MW installed.
Solar overtakes wind in installed capacity, but not yet in production. With 550 MW installed vs 213.74 MW for wind, solar is now the leading technology by capacity. But wind still leads in annual production (467 GWh vs 360 GWh) due to its higher load factor. At current growth rates, solar is expected to overtake wind in production within a few years.

Biomass and cogeneration installations form the third national renewable source. In Luxembourg, this includes large industrial wood-waste cogeneration units (one ~250 GWh/year installation planned in the NECP), biogas plants (organic waste fermentation), and waste incineration units (of which 53.7% of incinerated waste is of renewable origin, per an ILR-commissioned audit). Between 2017 and 2021, it was largely through three large biomass cogeneration installations that Luxembourg’s renewable production grew by over 62%, according to the NECP update.
5. Hydropower: Vianden, Europe’s pumped-storage giant
Luxembourg hosts one of Europe’s largest pumped-storage power plants: the Vianden plant, on the upper Our River at the German border. With 1,296 MW installed capacity (11 units), it is the country’s largest energy infrastructure by capacity — far exceeding the rest of the electricity park combined. It is owned by the Société Électrique de l’Our (SEO), with the Luxembourg State and RWE each holding 40.3%. The plant pumps cheap German electricity at night (storing energy in the upper reservoir) and releases it during peak demand. Average annual production is around 1,650 GWh — but net of pumping consumption, it is a net energy consumer over the year.
Soler also operates three run-of-river hydroelectric plants — at Esch-sur-Sûre, Rosport and Ettelbruck — which produce genuinely renewable electricity counted in Luxembourg’s local renewable statistics. These smaller plants generate energy proportional to the river’s natural flow and are counted towards the country’s renewable production targets.
6. Self-consumption and energy communities
Since 2021, Luxembourg law allows both individual self-consumption (directly using electricity from your own panels) and renewable energy sharing between neighbours — in the same building or nearby. The ILR manages the dedicated platform weshareenergy.lu with rules, a simulator and all necessary tools. By 31 July 2025, 736 active sharing groups were registered. Individual self-consumption installations quadrupled in 2023 alone (from 1,238 to 4,249 PV self-consumption installations), and shared production tripled to ~198 GWh.
The tax benefits of self-consumption and sharing (exemption from network charges and compensation fund contributions on shared volumes) are conditional on signing a sharing agreement with your grid operator. Without this agreement, even if you physically share energy with neighbours, the benefits don’t apply. Use the simulator on weshareenergy.lu to model a sharing group for your building.
7. Technology comparison in 2026
| Technology | Installed capacity (2024) | Production 2024 | Share of national production | Trend |
|---|---|---|---|---|

8. NECP 2030 targets: where do we stand?
The updated NECP targets 37% renewables in gross final energy consumption by 2030 and 3,032 GWh of national renewable electricity production. In 2024, production reached 1,443 GWh (22.8%) — roughly halfway to the production target. The remaining gap requires another near-doubling in 6 years, with 1,236 MW of solar (+686 MW vs 2024) and 453 MW of wind (+239 MW) to be installed. The 2024 pace of solar installation (156 MW in a single year) is encouraging, but wind development must also accelerate significantly.
Electricity alone is not enough: the 37% target applies to gross final energy consumption, which includes heating, transport and industry — still heavily fossil-based in Luxembourg. Reaching the target requires not just more solar and wind, but also massive electrification of heating (heat pumps) and mobility (EVs). Hence the growing importance of electricity contracts adapted to these new uses.
9. Impact on your electricity contract
All Luxembourg residential suppliers now offer « green » electricity — but with significant differences in actual origin. Energy Revolt sources 100% locally from Luxembourg producers (in 2023, its producers’ output exceeded client consumption). SUDenergie’s Mäi Stroum is 100% Luxembourg wind. Sudstroum offers 100% certified renewable (hydro and wind). Enovos, NordEnergie and Steinergy offer TÜV-certified European renewable electricity. If you have solar panels or a heat pump, specialised contracts (dual-rate billing, surplus management, energy community participation) are available — see our dedicated guides: suppliers for solar panels and suppliers for heat pumps.
