The Energy Policy Act of 2005 (Act) contains provisions that address a variety of challenges that face the geothermal industry, including the high risk and uncertainty of developing geothermal power plants, lack of sufficient transmission capacity, and delays in federal leasing. Among the provisions are means to simplify federal royalties on geothermal resources while overall collecting the same level of royalty revenue. The Act also changes how these royalties are to be shared with local governments (disbursements). This report describes: (1) the current extent of and potential for geothermal development; (2) challenges faced by developers of geothermal resources; (3) federal, state, and local government actions to address these challenges; and (4) how provisions of the Act are likely to affect federal geothermal royalty disbursement and collections.
Geothermal resources currently produce about 0.3 percent of our nation's total electricity and heating needs and supply heat and hot water to about 2,300 direct use businesses, such as district heating systems, fish farms, greenhouses, food-drying plants, spas, and resorts. Recent assessments conclude that future electricity production from geothermal resources could increase by 25 to 367 percent by 2017. The potential for additional direct use businesses is largely unknown because the lower temperature geothermal resources that they exploit are abundant and commercial applications are diverse. One study has identified at least 400 undeveloped wells and hot springs that have the potential for development. In addition, the sales of geothermal heat pumps are increasing. Developers of geothermal electricity plants face many challenges including a capital intensive and risky business environment, developing technology, insufficient transmission capacity, lengthy federal review processes for approving permits and applications, and a complex federal royalty system. Direct use businesses face unique business challenges, remote locations, water rights issues, and high federal royalties. The Act addresses many of these challenges through tax credits for geothermal production, new authorities for the Federal Energy Regulatory Commission, and measures that streamline federal leasing and that simplify federal royalties, which totaled $12.3 million in 2005. In addition, the Department of Energy and the state of California provide grants for addressing technology challenges. Furthermore, some state governments offer financial incentives, including investment tax credits, property tax exclusions, sales tax exemptions, and mandates that certain percentages of the electricity within the state be generated from renewable resources. Under the Act, federal royalty disbursement will significantly change because half of the federal government's share will now go to the counties where leases are located. Although the Act directs the Secretary of the Interior to seek to maintain the same level of royalty collections, GAO's analysis suggests this will be difficult because changing electricity prices could significantly affect royalty revenues. Also, MMS does not collect sales data that are necessary to monitor these royalty collections.
Recommendations for Executive Action
Status: Closed - Implemented
Comments: MMS addressed this recommendation by: identifying, requesting, and receiving documentation from three payors to correct erroneous and missing geothermal royalty data for the period September 1999 through April 2007.
Recommendation: To assist in achieving the same level of geothermal royalties as would have been collected prior to the Energy Policy Act of 2005, the Secretary of the Department of the Interior should instruct the appropriate managers within the Minerals Management Service to correct erroneous and missing royalty data, when necessary, so that it will have an accurate baseline of royalty collections for each payor.
Agency Affected: Department of the Interior
Status: Closed - Implemented
Comments: MMS addressed this recommendation and improved its geothermal royalty collections program by: revising Chapter 7 of the Minerals Reporter Handbook to require payors of leases issued after August 8, 2005 to report gross proceeds from the non-arm's-length sales of electricity as "sales value" on the Form MMS-2014.
Recommendation: To assist in achieving the same level of geothermal royalties as would have been collected prior to the Energy Policy Act of 2005, the Secretary of the Department of the Interior should instruct the appropriate managers within the Minerals Management Service to routinely collect from royalty payors the gross sales revenues for electricity sold in order to compare these revenues with past royalty collections and to verify compliance with the percentages prescribed within the Act for leases to be issued in the future.
