ECMWF AIFS Weather Model: 2026 Upgrades & Energy Trading

1 / 5

The ECMWF AIFS v2 upgrade from May 2026 adds wave and snow cover forecasts and improves medium-range skill for 100 m wind and surface solar radiation, which directly affect renewable energy P&L.

2 / 5

AIFS Single and AIFS ENS now run alongside the physics-based IFS, yet still depend on external platforms for live benchmarking, natural-language analysis, and power-forecast integration.

3 / 5

EPT-2 outperforms ECMWF HRES on every lead time for 10 m wind, 100 m wind, 2 m temperature, and surface solar radiation, and EPT-2e beats the 50-member ECMWF ENS mean on RMSE and CRPS at virtually every lead time.

4 / 5

Energy traders gain the most value when they run multiple models under one schema with frequent updates, 15-minute power forecasts, and roughly 90-second Athena briefings, which the Jua platform delivers natively.
