Geothermal Production Expansion Act - Amends competitive lease provisions of the Geothermal Steam Act of 1970 to set forth conditions under which areas that adjoin federal lands for which a qualified lessee holds a legal right to develop geothermal resources may be made available to the lessee for noncompetitive lease at the fair market value per acre.
Includes as such conditions that sufficient data has been submitted by a qualified geothermal professional to the relevant federal land management agency to engender a belief that: (1) there is a valid discovery of geothermal or geothermal steam resources on the lands for which the lessee holds the right to develop the resources; and (2) the thermal feature extends into the adjoining areas.
