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 August 2026, on each one's flagship offer.
| Criterion | Enovos — naturstroum FIX | SUDénergie — Mäi Stroum |
| Energy price | 10.90 c€/kWh ✅ | 11.25 c€/kWh |
| Monthly bill (1,800 kWh/year) | €41.73/month ✅ | €42.84/month |
| Price type | Fixed, guaranteed up to 3 years ✅ | Variable indexed |

| Discounts | connect discount −€30/year | SEPA + e-invoice −€18/year |

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.
