pipeline, the pipeline was oversized with 2400 ft of 18 in and 300 ft of 16 in steel pipe. All pipe installed as part of this project (including the hot water supply and return lines) were recycled or reused from other projects around the state. The cold water gains 9-10 oF in the condenser before being discharged to Monument Creek, which runs along the northern boundary of the Chena Hot Springs property via an existing drainage ditch. An automated shutdown procedure is in place to avoid the potential for refrigerant discharge into Monument Creek if a leak in the condenser is detected. The second ORC unit was designed to be either air or water cooled by installing a separate air cooled condenser adjacent to the power plant building. The air condenser fans draw an additional load of 24kW, however they allow for an increase in net generating capacity at sub zero temperatures, which are common at Chena during the winter months. During the summer, the unit is reconfigured by turning two manual valves to use a water cooled condenser identical to the one installed in ORC1. In fact, the air cooled system has worked so effectively, a second air cooled condenser has been ordered and will be installed on the first ORC unit for use next winter. Maximum net power generated during winter operation was 220 kW, at an ambient temperature of -43 oF. HOT WATER SUPPLY AND REINJECTION SYSTEM All available geothermal waters in the vicinity of Chena Hot Springs have been sampled and analyzed for their basic brine chemistry, stable isotopes, total organic carbon and dissolved inorganic carbon as part of the Department of Energy funded GRED III project (Holdmann, Benoit, and Blackwell, 2007). Quartz and Na-K-Ca geothermometers predict temperatures as high as 278 and 263 oF respectively as the base temperature of a deeper resource at Chena. These temperatures are expected to be accessed at depths of 1500 to 2500 ft, according to the model developed through the Chena GRED III project. The Chena thermal spring waters are quite dilute for thermal waters, having a total dissolved content of only 300 to 388 mg/l, with a pH near 9. This has made selecting materials for the power plant heat exchangers somewhat easier than usual for a geothermal fluid, however there are still concerns about the sulfur content and reactions with the copper alloy (90/10 Cu-Ni) as well as potential oxidation in the evaporator units. This causes some minor pitting and scaling which has been observed in the evaporator tubes, and ultimately it may be necessary to inject a corrosion inhibitor into the hot water supply, as is common in many other geothermal installations. This issue is still being researched. Development as part of the current power generation project has focused on the shallow geothermal system, and extensive testing of the resource has determined the upflow zones lies approximately 1500 ft to the west of the natural hot springs area. Test wells with the highest artesian pressures and temperatures were drilled in this area during 2006. Prior to 2006, drilling had focused on the area immediately surrounding the hot springs and extending toward the east. It has now been established from clear rollovers in the temperature depth curves that this area is part of the outflow plume, and not the source of the upflow. 4PDF Image | Chena Hot Springs 400kW Geothermal Power Plant
