If your electricity tariff follows the spot market — or you simply want to understand why your bill looks the way it does — the number that matters is the day-ahead price for your bidding zone. It is published every afternoon for the next day, it swings wildly between hours, and most people have never seen it. This board shows it: every zone, every hour, live.
What are day-ahead electricity prices?
European power is traded zone-by-zone on exchanges like EPEX and Nord Pool. Tomorrow’s prices are settled today around noon: a price for every hour of the coming day, driven by forecast demand, wind and solar output, plant availability and cross-border flows. The result is a curve that can go negative at sunny windy midday and spike hard during the evening peak.
Why do the cheapest hours matter practically?
Because flexible loads can chase them. An EV scheduled to charge at the overnight minimum instead of the 19:00 peak, a heat pump pre-heating during the solar dip — on a dynamic tariff the difference between the day’s cheapest and most expensive hour is routinely several-fold. The board makes the day’s cheapest windows visible at a glance, per zone.
Why do prices differ so much between zones?
Zones are coupled but not identical — grid bottlenecks between bidding areas mean Scandinavia can sit near zero with hydro and wind while a neighboring zone spikes. Watching several zones side by side makes Europe’s generation mix differences concrete: wind fronts, solar noon, and low-demand weekends all leave fingerprints on the curves.
Who uses this?
Anyone on a spot-linked tariff, EV owners scheduling charges, home-automation tinkerers wiring price thresholds into switching, and energy nerds who like watching the duck curve form in real numbers.
