Safe to train on
Built only from a named, redistributable official source under a documented open licence - not scraped web data. No copyright grey zone, no personal data. Ships machine-readable Croissant metadata (ML Commons - loads in Hugging Face / Kaggle / Google), an AI training-licence manifest documenting source, licence and provenance for your model's data governance, and a machine-readable data dictionary (drop it into an agent / RAG prompt so the model knows every column) - all inspectable before you buy.
What's included
- Wind+solar forecast error = actual - forecast (MW), all ~40 EU zones, 2018-2026
- Positive = more renewables than forecast (downward price pressure)
- Aligned on zone+ts; the headline imbalance driver
- Feeds imbalance, intraday and battery-arbitrage models

Australian Power Grid (AEMO NEM)
The spot price and operational demand of Australia's National Electricity Market - one of the most volatile power markets on earth (huge solar/wind, grid batteries, price spikes to the market cap). AEMO publishes the Regional Reference Price (RRP, AUD/MWh) and operational demand (MW) per NEM region as one CSV per month × region; we stitch them into one clean multi-region, multi-metric Parquet - 5-minute from Oct-2021, 30-minute before. Mirrors the ENTSO-E / EIA / Elexon power products, extending the grid suite to the Australian continent.
