- beats naive baseline
Live from the exchange. Members get the full quarter-hour series, weather overlays, and day-ahead model forecasts on top.
Not another dashboard — the data layer underneath one.
An automated pipeline, not a consultancy. Every number is reproducible from open sources, timestamped in UTC, and traceable to the scrape and model version that produced it.
Collect, automatically
Scrapers pull the TGE day-ahead auction, the PSE/KSE grid plan, German fundamentals, weather for 15 Polish cities, and fuel & carbon closes — into one schema, deduplicated and merge-on-refill so a late scrape never overwrites a known value.
Forecast the next day
LightGBM models turn prices, weather and grid fundamentals into next-day FIXING_I and FIXING_II forecasts, quarter-hour by quarter-hour — retrained on every run and versioned to the exact git commit that produced them.
Publish the accuracy
Every run records its holdout MAE and RMSE against naive baselines, plus a train/test drift score that flags when a forecast is extrapolating into an unfamiliar regime. No black boxes — you see how good each prediction actually was.
Browse & export
One read-only console for the whole stack: filterable price tables, weather overlays, source-freshness at a glance, and CSV export on every view. See exactly what is current and what has gone stale.
