A valuable wind resource not only means strong winds when electricity demand or price is highest, but also a resource that performs at expected levels over the life of the project. Wind Site Climate Variability Analysis (CVA) delivers critical long-term resource data to help increase your confidence in the production potential of a proposed wind site and put available site observations into historical context.

HIGH-RESOLUTION, LONG-TERM ANALYSIS

Using proven, state-of-the-art techniques, 3TIER delivers high-resolution information and advanced analysis of both the wind resource and expected power output at any 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 variability for periods of up to 50 years and at horizontal resolutions down to a few meters. Our reports give you a complete picture of the annual, monthly, and hourly variation in wind speed and energy output at your specific location. Time series data files covering the full period of the analysis are also provided to facilitate further analysis.

ENHANCED ACCURACY

When on-site observations are available, 3TIER can dramatically reduce error and model bias by integrating these observations using an advanced statistical technique known as MOS (Model Output Statistics). This process provides the most accurate estimates of wind speed and power possible. To demonstrate this, an accompanying validation shows the improved results by comparing the model derived time series and the MOS-corrected time series with the provided period of observations.
