Solar Energy Zones

 Full Resource Map

The 2012 Solar PEIS Record of Decision (ROD) identified 17 solar energy zones (SEZs) on about 285,000 acres [1,553 km²] of Bureau of Land Management (BLM)-administered lands. These SEZs are identified as Designated Leasing Areas (DLAs) in BLM's leasing regulations (43 CFR 2800). The 2012 Solar PEIS ROD defined SEZs as areas well suited for utility-scale production of solar energy, where the BLM will prioritize solar energy and associated transmission infrastructure development. The Agua Caliente SEZ (AZ) and the West Chocolate Mountains SEZ (CA) were identified in subsequent planning efforts. A discussion of the criteria used to identify SEZs is provided in Section 2.2.2.2 of the Draft Solar PEIS (PDF, 790 KB).

The map below shows the locations of the SEZs (current as of 2021). Click the sun icons or labels in the map, or follow the links below the map to learn more about each SEZ.

The Solar PEIS ROD further facilitated development in SEZs by establishing:

• SEZ Policies for developing regional mitigation strategies, conducting monitoring and adaptive management, and incentivizing development in SEZs;
• Protocols for identifying new or expanded SEZs; and
• Procedures for withdrawal of SEZ lands
