Land-use screens are map-based footprints delineating important environmental and physical characteristics of the land. They are assembled from an integration of raw data into modeled results at the statewide scale and can show access limitations or competing land-use priorities. Land-use screens are a key input to several state electricity planning processes. Since 2008, the CEC, the California Public Utilities Commission, and the California Independent System Operator have used spatial environmental and land-use data, including land-use screens, to guide their relevant energy resource planning. For the 2022 Integrated Energy Policy Report Update, the CEC started a process to revise the land-use screens used in state electricity planning processes. The final staff report and online web mapping application document the revised land use screens.
