Day-ahead wholesale prices, EUR/MWh — reference only, not investment advice, and not a live trading feed.
Great Britain isn't shown: it isn't part of this data source's day-ahead price coverage at all. Spain and Ireland are also left out here — Energy-Charts' own license marks their price zones "internal use only," so they aren't shown on this public page even though their generation data is elsewhere on this site.

Current 15-minute periodSource: Energy-Charts API (Fraunhofer ISE) — CC BY 4.0 licensed zones only. Loads slowly on a cold cache (roughly one zone every 2.5s) to respect the upstream API's 2-requests/minute limit on this endpoint; cached for 30 minutes after that.
