European day-ahead electricity price map
The map organizes electricity prices by bidding zone: a market area within which a common day-ahead price applies for a given delivery interval. Bidding zones do not always follow country borders. Some countries contain several zones, so selecting a market area gives a more precise view than treating every country as a single price.
Public map colors, charts and summaries use canonical EUR/MWh, meaning euros per megawatt-hour. This common unit supports comparison across zones. Select a zone to inspect its price profile, then use the date and dataset controls to explore another delivery period. The map and detail panel work together to connect the geographic pattern with the underlying time series.
Interval view shows prices for individual delivery periods. Daily, Weekly and Monthly views provide a broader perspective through period summaries and the selected metric. Comparing these views helps distinguish a short price spike from a pattern that persists across days. Check the displayed period and coverage status when comparing values, especially for current or incomplete periods.
What day-ahead electricity prices show
Day-ahead prices refer to scheduled electricity delivery periods traded ahead of the delivery day. They vary over time and between bidding zones as market conditions change. A price for one interval describes that interval, while a daily or longer-period summary combines information from its included delivery intervals.
Negative prices and high prices are legitimate market outcomes. They can reflect the balance of supply and demand, generation availability and constraints on moving electricity between areas. A negative wholesale price does not mean that a household electricity bill becomes negative: retail contracts, network charges and taxes are separate from the market prices shown here.
Eurospotting visualizes published source market data rather than forecasting prices. Published intervals later in the delivery day are still day-ahead market observations, not predictions. Read more about Eurospotting and its scope as an independent project.
Data source and methodology
The primary day-ahead source is the ENTSO-E Transparency Platform. Eurospotting transforms source records for comparison and display while retaining their delivery-period context. It is an independent interface, not the official publisher. The data sources page explains provenance, availability and revisions.
Delivery timezones, daylight-saving transitions and differing source resolutions are handled explicitly. A delivery day can be shorter or longer when clocks change, and source intervals can represent 15, 30 or 60 minutes. Missing or partial data is not fabricated to complete a chart or period. Consult the methodology for interval handling, comparable values and coverage rules.
