The Blundell Geothermal Power Plant is a singleflash plant with a net capacity of 23 MWe (26 MWe gross). The geothermal brine is produced from four wells that tap highly fractured crystalline rock of the Roosevelt Hot Springs geothermal resource. This geothermal resource is a hydrothermal field where groundwater is heated by underlying magma. Production depths generally range from between 1,253 to 7,321 ft (382-2,231 m) at reservoir temperatures of 464 F to 514 F (240-268 C)
