Best NWP Model Accuracy 2026: EPT-2 Tops Every Lead Time

1 / 5

EPT-2, Jua’s physics foundation model, beats ECMWF HRES on every lead time and every energy-critical variable from 0–240 hours.

2 / 5

EPT-2e outperforms the 50-member ECMWF ENS mean on both RMSE and CRPS at virtually every lead time, so traders get stronger probabilistic signals.

3 / 5

Short-range (0–24 h) and medium-range (1–10 day) gains convert directly into lower imbalance costs and sharper trading decisions.

4 / 5

EPT-2 runs on a single GPU at about 0.25 kWh and updates up to 24 times per day, at roughly four orders of magnitude lower cost than traditional NWP.
