The geospatial data reflected in the protected area layer mostly pertain to natural and wilderness areas where development of utility-scale renewable energy is prohibited and were heavily based on RETI 1.0 blackout areas.1 The protected area layer is distinguished for solar PV technology by the BLM greater sage grouse habitat management area which provides separate exclusion areas for the different technology types. Tables 1 and 2 below lists the data sources and precise selection query for each dataset, if applicable, that make up the protected area layer.Table 1: Datasets used in the Protected Area Layer
