Wind Resource Grids

Wind Resource Grid (WRG) datasets are essential for siting met towers, designing layouts, and obtaining precise wind energy estimates. Available in 50m and 200m resolution, WRG datasets are compatible with all leading wind farm design and optimization packages, including OpenWind.

Sitewind®

Premium 50m Resolution

UL Solutions's advanced wind flow modeling system designed for precision micrositing. Combines mesoscale and microscale atmospheric models for optimal wind farm design and optimization.

Technical Overview

Mesoscale Model: Weather Research and Forecasting (WRF) with 1 km grid spacing
Microscale Model: WindMap mass-conserving flow model at 50m resolution
Accuracy: Captures local topography and surface roughness influences

Best Practice: Combine WRG with on-site measurements using adjustment tools in OpenWind for optimal results.

WRG 200m

Fast & Cost-Effective

An economical and efficient solution for initial wind farm development stages. Ideal for preliminary design and energy assessments before on-site measurements are available.

Key Features

Methodology: WindMap microscale model initialized with virtual met mast
Calibration: Scaled to Windnavigator's 200m wind speed maps for minimal bias
Use Case: Early-stage assessments and preliminary site evaluations

Note: Not intended for detailed plant design or definitive energy production estimates. Upgrade to Sitewind® for final assessments.
