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.
FAQ — Viana do Castelo
How is the electricity price determined?
Day-ahead prices are set each morning around 12:00 WEST by Nord Pool / EPEX, where suppliers and producers across Europe submit bids for each hour of the next day. The cheapest mix that meets demand wins, and that price applies to everyone in the bidding zone for that hour.
When is electricity cheapest?
Typically late at night (00:00–04:00) and around midday on sunny/windy days when renewables overproduce.
Can electricity prices go negative?
Yes. When wind + solar overproduce on a low-demand day, wholesale prices can drop below zero. This happens 50–100 hours per year in renewables-heavy zones.
Why is my electricity bill higher than the spot price?
The spot price is just one component. Your retail bill also includes electricity tax, grid/network fees, VAT and a supplier markup. Add roughly 30–60 % on top of the wholesale spot price to estimate your true per-kWh cost.
