Why Prezio
The full price of electricity is hard to pin down
01 · Asking users
Most users can't tell you their price
My electricity price0.30 €/kWh
last updated 14 months ago
Typed-in prices go stale fast, and every calculation downstream inherits the error.
02 · Three parts to every price
Energy is only ~30% of the bill
EnergyGrid feesTaxes and levies
Energy-only data stops here
Grid fees, taxes and levies make up the rest, and they vary more and more by hour, season and power peak.
03 · Building it in-house
Building it yourself becomes a second product

A realistic DIY setup: market prices solved, the rest partial, stale or missing.

FAQ

Answers about coverage, tariff types, the onboarding flow and plans.
Ask us a questionPrezio is an electricity price API for energy apps in Europe. For an address, it returns the full price per kWh for every 15 minutes, split into the retailer tariff, grid fees, taxes and levies.
Prezio is live in 17 European countries: Austria, Belgium, Denmark, Estonia, Finland, France, Germany, Great Britain, Ireland, Latvia, Lithuania, Netherlands, Norway, Poland, Romania, Spain and Sweden. The coverage page lists the retailers, grid operators and tariff types per country, and the countries in preparation.
Each price is split into its components: the retailer's energy price and standing charges, grid fees (including capacity or demand charges where they apply), taxes, levies and VAT. The components add up to the total price for each interval.
Yes. Prezio covers fixed, time-of-use and dynamic (spot-based) tariffs. The /live endpoint returns prices for today and tomorrow in 15-minute intervals, so every tariff type comes in the same format. Dynamic tariffs use day-ahead prices from Nord Pool, under license. In bidding zones that are part of European market coupling, these are the same day-ahead prices that EPEX SPOT publishes.
Yes, where the grid operator publishes them. Time-variable grid fees under §14a EnWG module 3 are part of the grid tariff, so they appear in the grid component of each 15-minute interval.
No. In the Onboard flow, users enter their address and confirm their tariff from a list. Prezio adds the grid operator and taxes for that address. Some tariffs need one or two extra answers, such as the meter type or the subscribed capacity.
Yes. Typical uses are EV charging costs and driver reimbursement, heat pump and battery scheduling, solar export decisions and cost reporting across many homes. Prezio provides the prices, and your product decides when each device runs.
