Washington, D.C., July 25, 2012 — The Department of the Interior, in partnership with the Department of Energy, will publish the Final Programmatic Environmental Impact Statement (PEIS) for solar energy development in six southwestern states — Arizona, California, Colorado, Nevada, New Mexico and Utah.
The final Solar PEIS represents a major step forward in the permitting of utility-scale solar energy on public lands throughout the west.
The announcement builds on the progress made in fostering renewable energy development on public lands. When President Barack Obama took office, there were no solar projects permitted on public lands; since 2009, DOI has approved 17 utility-scale solar energy projects that, when built, will produce nearly 5,900 MW of energy — enough to power about 1.8 million American homes.
The Solar PEIS will serve as a roadmap for solar energy development by establishing solar energy zones with access to existing or planned transmission, the fewest resource conflicts and incentives for development within those zones. The blueprint’s comprehensive analysis will make for faster, better permitting of large-scale solar projects on public lands.
The Solar PEIS planning effort has focused on identifying locations on Bureau of Land Management (BLM) lands that are most suitable for solar energy development. These areas are characterized by excellent solar resources, good energy transmission potential, and relatively low conflict with biological, cultural and historic resources.
The Final PEIS identifies 17 Solar Energy Zones (SEZs), totaling about 285,000 acres of public lands, as priority areas for utility-scale solar development, with the potential for additional zones through ongoing and future regional planning processes.
The blueprint also allows for utility-scale solar development on about 19 million acres in “variance” areas lying outside of identified SEZs. In total, the Final PEIS estimates a total development of 23,700 MW from the 17 zones and the variance areas, enough renewable energy to power 7 million American homes.
In support of more detailed system-level analyses of transmission needs, the BLM is engaged in ongoing transmission planning efforts, including through the Transmission Expansion Planning Policy Committee and the Western Electricity Coordination Council’s transmission study.
The July 27 Federal Register Notice of Availability for the Final PEIS will begin a 30-day protest period, after which Secretary Salazar may consider adopting the document through a Record of Decision.
The BLM released the Draft Solar PEIS in December 2010, and in response to the over 80,000 comments received from cooperating agencies and key stakeholders, issued a Supplement to the Draft Solar PEIS in October 2011.
