U.S. Geothermal Updates Status of New San Emidio Power Plant

U.S. Geothermal HTM announced that its engineering, procurement and construction contractor experienced a pump failure at the new 8.6 net megawatt San Emidio, Nevada power plant. The EPC contractor advised that, while they were commissioning the plant, a key process pump used to move R134a working fluid through the binary cycle system experienced a mechanical failure. The contractor removed the pump and shipped it to a repair facility. It is currently scheduled to be back on site for installation Monday, February 27, 2012. After the pump is reinstalled, the EPC contractor will resume power plant commissioning activities. The damaged capacitors discussed in our February 2, 2012 news release have been replaced.
