The DOE and Sandia are working toward a better integration of new wind turbines with their local environment. One barrier to wind-energy installations has been the impact wind turbines may have on the National Air Space (NAS) radar system, which has led to a blanket rejection of several wind-farm developments. To improve the siting and permitting process for wind-energy developments in the vicinity of radar systems, Sandia is working with BEM International and Peak Spatial Enterprises to develop a Tool for Siting Planning and Encroachment Analysis for Renewables (TSPEAR) toolkit.
Initially designed to support wind-energy development by assessing the interaction between turbines and constraining factors, such as the NAS radar systems, TSPEAR is partially populated with information from existing databases and can integrate custom models and tools used throughout the development process. Sandia is working with MIT’s Lincoln Laboratory to validate TSPEAR results against the Interagency Field Test and Evaluation experimental campaigns that measured radar performance over and around several wind farms.
