Problem
Legacy weather forecasts used in energy markets suffer from low spatial and temporal resolution, small underdispersive ensembles, and discontinuous coverage across time horizons, causing missed extreme events and inaccurate risk assessments for grid operators and market participants.
Solution
Sunairio ONE delivers a next‑generation, omniscale ensemble forecasting platform that integrates high‑resolution weather data with energy‑specific variables. Trained on the Sunairio High‑resolution Earth Data (SHED) at 3 km resolution, the system generates a 1,000‑member ensemble that accurately captures tail risks and provides calibrated probability distributions. The platform offers seamless coverage from short‑term (18 hour) to long‑term (15 year) horizons, updating forecasts hourly to daily depending on the range. All outputs—including turbine‑height‑adjusted wind, satellite‑derived irradiance, load, and a proprietary Grid Stress Index—are delivered at hourly intervals, enabling precise, actionable risk management for power system planning and market trading.
Target Audience
Primary customers are grid operators, energy traders, renewable asset managers, and utility planners who require high‑fidelity weather‑driven risk assessments across multiple time horizons.
Features
- 1,000‑member ensemble paths delivering calibrated probabilities and full‑spectrum extreme event visibility
- 3 km (or finer) spatial resolution and hourly temporal resolution using the SHED dataset, 100× finer than standard reanalysis products
- Continuous forecast coverage: 18‑hour short‑term (hourly updates), 15‑day medium‑range (6‑hour updates), 12‑month seasonal (weekly updates), and 15‑year long‑term (annual updates)
- Integrated energy variables: turbine‑height‑adjusted wind speeds, satellite‑based irradiance, load forecasts, generation outage modeling, and Grid Stress Index
- Coverage of all major U.S. ISOs/RTOs and utility‑scale wind and solar assets, with zonal and aggregate data
- API and web dashboard access for seamless integration into trading, planning, and risk‑management workflows
