Why your bill is higher than the spot price
The prices on this page are wholesale day-ahead — what suppliers pay on the Nord Pool / EPEX market. Your final retail bill adds:
| Component | Type | Approx (EU avg) |
|---|---|---|
| Wholesale spot price | Variable (this page) | — |
| Electricity tax / excise | Fixed | € 0.005 – 0.20 /kWh |
| Grid / network fee | Fixed + variable | € 0.05 – 0.15 /kWh |
| VAT / sales tax | % multiplier | 20 – 25 % |
| Supplier markup + monthly fee | Provider-specific | € 0.005 – 0.05 /kWh |
Rule of thumb: add 30–60% on top of the wholesale spot price to estimate your true per-kWh cost. The exact split depends on your country, your grid operator, and your contract type.
