Developing Plants in the United States

Up to 7057.26 MW of new geothermal power plant capacity is currently under development in the United States (this includes projects in the initial development phase). There are a total of 152 geothermal projects confirmed to be in development as of April 2010, representing a 26 percent increase in the number of developing projects reported in March 2009. The 15 states with projects currently under consideration or development are: Alaska, Arizona, California, Colorado, Hawaii, Idaho, Louisiana, Mississippi, Nevada, New Mexico, Oregon, Texas, Utah, Washington, and Wyoming. GEA's 2010 US Geothermal Power Production and Development Update provides a detailed analysis of US geothermal projects in development, including individual project data by state and a discussion of 2009 American Recovery and Reinvestment Act (ARRA) funding for geothermal development.

Developing Projects by State:

The projects listed for each state are categorized by the following phases:

  • Phase 1: Identifying resource, secured rights to resource, pre-drilling exploration
  • Phase 2: Exploration and/or drilling permits approved, exploration drilling conducted/in progress
  • Phase 3: Securing PPA and final permits, full size wells drilled, financing secured for portion of project constructed
  • Phase 4: Plant permit approved, facility in construction, production and injection drilling underway
  • Unconfirmed: Project information obtained by GEA from publicly available sources but not verified by the project developer
  • NOTE: GEA is reporting project information that is provided by developers or public sources. We do not independently verify the data provided or warrant its accuracy.

     

    Alaska
    Seven geothermal companies, resorts, utilities, and Native American organizations are currently developing a combined 80 MW of geothermal power for electricity production in Alaska.

    Louisiana
    Louisiana currently hosts two known developing geothermal projects. One is a planned geothermal hydrocarbon co-production (GHCP) unit, and another which is expected to develop geopressured resources at an oil and gas field. The latter project received ARRA funding. These installments could yield 5.3 MW installed capacity for the state when completed.

    A planned expansion to the 0.24-MW pilot installation project brought online in 2008 is currently underway. The full project, Lightning Dock, is expected to produce 15 MW. Another 20-MW project is in development, bringing New Mexico's current developing geothermal power capacity to 35 MW. Seven EGS R&D and innovative exploration technology projects in the state received DOE funding, none of which have been identified as being currently in development.

    Texas
    Texas' first geothermal project is a planned geothermal hydrocarbon co-production (GHCP) unit expected to produce 0.4 MW geothermal power. DOE awarded funding to 13 recipients in the state for research in areas ranging from EGS R&D to innovative exploration technologies. Texas has a great advantage in drilling for geothermal resources as the state has access to detailed subsurface analyses of heat resources, reservoirs, and deep water availability due to the oil and gas drilling throughout the state.
