,The site suitability criteria included in the techno-economic land use screens are listed below. As this list is an update to previous cycles, tribal lands, prime farmland, and flood zones are not included as they are not technically infeasible for development. The techno-economic site suitability exclusion thresholds are presented in table 1. Distances indicate the minimum distance from each feature for commercial scale wind development,Attributes:,,

,The wind techno-economic exclusion layer has been updated for proposed use in the current 2026-2027 IRP cycle. The previous version was developed in 2023. Two changes are reflected in this current draft update:,More information is found in the CEC and CPUC presentations from the August 19 webinar, as well as the 2023 Land Use Screens Staff Report in the CEC Energy Planning Library. ,,1.

For more information, contact John Hingtgen at John.hingtgen@energy.ca.gov. The map illustrates the variation in median plant capacity across the United States and California of wind plants with nameplate capacity of at least 1 MW. Median plant capacity depends on the statewide capacity and the number of plants 0 60 120 240 Miles within the defined area.,

This is the data set behind the Wind Generation Interactive Query Tool created by the CEC. The visualization tool interactively displays wind generation over different time intervals in three-dimensional space. The viewer can look across the state to understand generation patterns of regions with concentrations of wind power plants. The tool aids in understanding high and low periods of generation. Operation of the electric grid requires that generation and demand are balanced in each period.,

,This map illustrates the variety of median project capacity sizes across the United States and California counties for wind projects whose total nameplate capacity is greater than or equal to 1 MW. The absence of projects in the southeastern United States is attributable to low average wind speeds (United States - Annual Average Wind Speed, AWS Truepower and National Renewable Energy Lab). Hurricane strength winds are not usable with current technology. Median project capacity is a function of the statewide capacity and the number of projects within the defined area.
