OBSYD
The European electricity desk: day-ahead prices, load & residual load and generation mix for 37 European bidding zones — hourly everywhere, 15-minute where SDAC trades it — plus generation outages, cross-border flows, reservoir levels, forecasts and the gas that fuels the marginal price, with a live anomaly radar. From the official record (ENTSO-E, GIE) and Fraunhofer Energy-Charts. Descriptive, auditable, free & open source (AGPL-3.0).
