The U.S. Energy Department today announced $2.5 million for a new project to research the atmospheric processes that generate wind in mountain-valley regions. This in-depth research, conducted by Vaisala of Louisville, Colorado, will be used to improve the wind industry’s weather models for short-term wind forecasts, especially for those issued less than 15 hours in advance. With access to better forecasts, wind energy plant operators and industry professionals can ensure wind turbines operate closer to maximum capacity, leading to lower energy costs for consumers.
Data collected during the project will be shared in near real-time with the National Oceanic and Atmospheric Administration (NOAA) and the Energy Department’s national laboratories, and will be used to develop improved atmospheric simulations for theWeather Research and Forecasting model, a widely used weather prediction system. These new wind measurements and simulations will also be incorporated into NOAA’s Numerical Weather Prediction models to improve short-term wind forecasts in complex terrain.
This important research builds on the Energy Department’s Wind Forecast Improvement Project, which previously explored wind energy resources in the northern Great Plains and western Texas. For the first time ever, the Energy Department and NOAA used wind profiling radars and laser-based scanners known as LiDARs to assimilate wind data from tall turbines and nacelle anemometers into meteorological observations for use by the wind industry. Integrating these new data into existing models produced forecasts that were up to 15% more accurate at predicting future wind conditions in nearly flat terrain.
