3TIER has launched its Portfolio Climate Variability Analysis (CVA) in response to wind energy developers with large networks of met towers.
By enabling developers to put observational data into a long-term climatological perspective, Portfolio CVA reduces uncertainty about a location's wind energy value. Portfolio CVA is fully automated and can be deployed across portfolios of met towers ranging in size from several to several hundred, with observational data of varying durations within the portfolio. Every month Portfolio CVA takes the most recent month's observational data for each location, and compares that data to a 10-year-plus numerical weather prediction (NWP) model simulation for each location. It then returns the raw 10-year-plus, model-run data, as well as the model-run data corrected using the observational data for each location.
