Quick Start

Dashboard Overview

The EPF dashboard at epforecast.com provides access to day-ahead electricity price forecasts for Spain, Portugal, France, and Germany. The API supports both per-country queries (?country=ES) and batch endpoints (/forecast/combined/batch?countries=ES,PT,FR,DE).

What You’ll See

  1. Current Price — Live electricity price with 24h min/avg/max
  2. Tomorrow Outlook — Summary of D+1 forecast with cheapest hours
  3. Day-Ahead Forecast — 24-hour bar chart for tomorrow
  4. Price Heatmap — 7-day hourly price grid with color coding
  5. Strategic Outlook — D+2 to D+7 daily summary
  6. Forecast Chart — Multi-model overlay with confidence bands
  7. Price Drivers — Wind, solar, and demand context

Forecast Schedule

EPF delivers two forecast products daily for ES, PT, FR, and DE, aligned with the OMIE / EPEX SPOT market timelines:

ProductAvailableHorizonUse Case
D+1 Day-Ahead~10:00 UTCNext 24 hoursBidding strategy, next-day planning
D+2–D+7 Strategic~15:00 UTCNext 6 daysPortfolio optimization, maintenance scheduling

Both products include confidence intervals (50% and 90% bands) so you can assess forecast uncertainty at each horizon.

Reading the Forecast

Resolution

ES forecasts are available at 15-minute resolution (96 quarter-hours per day), aligned with the EU MTU15 standard that OMIE adopted in October 2025. PT, FR, and DE forecasts are delivered at hourly resolution.

Confidence Bands

Each point forecast comes with two confidence bands:

  • Inner band (50%) — Half of historical actuals fell within this range
  • Outer band (90%) — Nine out of ten historical actuals fell within this range

Wider bands indicate higher uncertainty — typically at longer horizons (D+5 to D+7) or during volatile market periods.

Multi-Model View

The Evaluation page lets you compare individual model predictions against actual prices across all four countries. Both the day-ahead and strategic products use a single-model XGBoost per country × horizon group (see XGBoost). The legacy LSTM-hybrid (v10.x) was retracted in April 2026 and the HistGBM+LightGBM+XGBoost ensemble was retired at the same cutover.
