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.
