An Omniscale Next-generation Ensemble
Sunairio ONE is your single solution for modern energy risk management.
Problem
We’ve solved the biggest problems with legacy forecasts
Existing weather forecasts have serious limitations that unnecessarily expose you to risk.
Small ensembles with misleading probabilities
Traditional ensemble forecasts are chronically underdispersive and produce just 30–50 ensemble members max — hiding tail risks and producing ensemble spreads that misrepresent actual probability distributions
Low spatial and temporal resolution
Low-resolution weather data without true hourly modeling leads to critical insight gaps; is insufficient for modeling site-specific weather at wind, solar, and load asset locations; and may hide extremes
Discontinuous and mismatched across scales
Short-term forecasts may not be consistent with history, medium-term forecasts abruptly end in the middle of contract periods, and seasonal models are not compatible with longer climate models — a disjointed landscape that challenges business decision-making
Solution
Sunairio ONE powers award-winning grid forecasting where weather, climate, and energy meet — for the next hour, the next decade, and anywhere in between.
