Using proven, state-of-the-art technologies, 3TIER can provide high-resolution information and advanced analysis of the long-term temporal characteristics of wind resources and power output at any established site or met tower location worldwide. 3TIER uses the latest mesoscale NWP (Numerical Weather Prediction) models and a proprietary methodology to give you a long-term perspective on resource variability for periods of up to 40 years and at horizontal resolutions as fine as 90 meters.

To increase your level of certainty in the potential capacity of a site, it is critical to understand how your wind resource performs. A valuable wind resource not only means strong winds when the electricity demand or the electricity price is highest, but also a wind resource that generates energy at expected levels over the long-term.

3TIER’s Wind Site CVA report provides a wealth of information on both long-term wind behavior and power capacity, including easily interpreted tables, graphs, plots, and wind roses. Our reports allow you to understand the annual, monthly, and hourly variation of wind speed and energy output at your specific location. In addition, time-series data files covering the full period of the analysis are included to facilitate further evaluation.

When on-site observational wind measurements are available, 3TIER can use these observations to significantly reduce RMSE (Root Mean Square Error) and model bias via a process called Model Output Statistics (MOS). An accompanying validation analysis illustrates the enhanced results by comparing the NWP time-series and the MOS-corrected time-series against the provided observational data.
