The U.S. Department of the Interior announced a plan on Wednesday to make more than 190 million acres of federal land in 12 western states available for development of geothermal energy resources, an initiative that could increase electric generation capacity from geothermal resources ten times over.
"Geothermal energy will play a key role in powering America's energy future," Secretary of the Interior Dirk Kempthorne said, "and 90% of our nation's geothermal resources are found on Federal lands. Facilitating their leasing and development under environmentally sound regulations is crucial to supplying the secure, clean energy American homes and businesses need."
Under the development scenario outlined in the plan--known as the Final Geothermal Programmatic Environmental Impact Statement--the initiative could produce 5,540 megawatts (MW) of new electric generation capacity from geothermal resources by 2015. That's enough to meet the power needs of 5.5 million homes. The plan also estimates an additional 6,600 megawatts by 2025 for a total of 12,100 megawatts--enough to power more than 12 million homes.
The plan would identify about 118 million acres of Bureau of Land Management-managed public lands and 79 million acres of National Forest System lands for future geothermal leasing. It would provide a list of appropriate stipulations to be applied to leases and amend 122 Bureau of Land Management land use plans to allow for geothermal development.
Kempthorne noted the strong interest states, local communities, industry and environmental groups took in the development of this plan. "This process has benefited greatly from the involvement of both governmental and non-governmental stakeholders, and from the clear direction Congress gave in the 2005 Energy Policy Act," the Secretary said. "It's really a model for working together to make decisions about our energy future."
Geothermal leasing revenues and royalties are shared with the States and counties where the leases are located, with 50% going to the State; 25% to the county and the remaining 25% to the Geothermal Royalty Fund of the Bureau of Land Management for investing in further geothermal planning and development.
In addition to laying the foundation for environmental analysis of future geothermal leasing, the plan also provides site-specific environmental analysis of 19 pending geothermal lease applications in seven geographic locations. These leases were filed before Jan. 1, 2005 for specific lands in Alaska, California, Nevada, Oregon and Washington managed by the Forest Service or the Bureau of Land Management. Decisions on the issuance of these 19 leases could proceed as soon as the Record of Decision is signed.
The governors of the 12 states in the plan's project area will each have the opportunity to review the final document to ensure consistency with state plans, programs, and policies. The Bureau of Land Management will wait until the end of the Governor's consistency review period before signing and issuing the Record of Decision approving the land use plan amendments.
Replenished by heat sources deep in the earth, geothermal energy is a renewable resource that generates electricity with minimal carbon emissions. Direct use of geothermal energy supplies heat for buildings, greenhouses, aquaculture, and other activities. It offers additional possibilities for reducing the need for conventional energy sources.
Growing interest in developing these resources is seen in the results of recent Bureau of Land Management geothermal lease sales in areas where current Resource Management Plans already allocate lands for such use. An August 2007 sale drew the highest-ever per-acre bid for a lease in California's famed Geysers field. And a sale of leases in Nevada brought a record-breaking $28.2 million in August 2008
A total of 29 geothermal power plants currently operate on Bureau of land Management lands in California, Nevada and Utah, with a total generating capacity of 1,250 MW.
The Bureau of Land Management and the U.S. Forest Service will publish the final version of a plan in the Federal Register on Friday, Oct. 24, 2008.
