Summary: The Energy Policy Act of 2005 (Act) contains provisions that address challenges to developing geothermal resources, 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 revenues. This testimony summarizes the results of a recent GAO report, GAO-06-629. In this testimony, GAO 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 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 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. The challenges to developing geothermal electricity plants include a capital-intensive and risky business environment, technological shortcomings, insufficient transmission capacity, lengthy federal review processes for approving permits and applications, and a complex federal royalty system. Direct-use businesses face numerous challenges, including challenges that are unique to their industry, 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 to streamline federal leasing and 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 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. Finally, MMS does not collect sales data that are necessary to monitor these royalty collections.
