Jersey Valley Geothermal Development Project Environmental Assessment: NV063-EAO8-091 2 PROPOSED ACTION AND ALTERNATIVES 2.1 PROPOSED ACTION 2.1.1 The Power Plant The Jersey Valley power plant will be an approximately 30 Megawatt (MW) geothermal power plant. The proposed power plant would be located in the SE1/4, SE1/4 Section 28 T.27N.. R.40E. A switching station, used to transform generated low voltage to the higher voltage required for a transmission line, would be constructed within the power plant boundaries as shown in Figure 4. A microwave communication tower would be about eight (8) feet tall; a radome antenna on a monopole; and attached to the power plant building. The tower will transmit to the Fencemaker microwave building/tower. It would also be built within the Jersey Valley power plant area and would consist of a microwave antenna, aimed west toward the existing communication link on the Tobin Range (NVN-57070). This system would be used to deliver signals from control centers and other remote locations, report operating status, and provide voice communication from dispatchers to power plant operators and maintenance personnel. This system would be considered an exclusive use communications system for Ormat. Permanent and temporary surface disturbance for the power plant can be found in Table 5. 2.1.1.1 Operation and Maintenance Procedures The Ormat power plant will utilize a binary design with an air-cooled heat rejection system. The geothermal fluids for the binary power plant will be produced from the production wells by pumping. Once delivered to the power plant, the heat in the geothermal fluid will be transferred to the “binary” (or secondary) fluid in multiple stage non-contact heat exchangers. The binary turbine units will use pentane (C5H12 ), a flammable but non-toxic hydrocarbon, as the binary fluid, which circulates in a closed loop. The heat from the geothermal fluid vaporizes the binary fluid, which turns the binary turbine and electrical generator to make electricity. The vaporized binary fluid exits the turbine and is condensed back into a liquid in a shell-and-tube, non-contact, air-cooled condenser. The condensed binary fluid is then pumped back to the heat exchangers for re-heating and vaporization, completing the closed cycle. The residual geothermal fluid from the heat exchangers is pumped under pressure out to the geothermal injection wells through the injection pipelines and injected back into the geothermal reservoir. The geothermal fluid will flow through the binary power plant in a closed system, with no emissions of non-condensable gases to the atmosphere.
