NPGS Monthly Dinner Meeting: Long-Term Performance of the Nevada Flash-Type Geothermal Projects – September 4, 2014

A note from NPGS: Come join NPGS at the Ramada on Thursday, September 4th–Dick Benoit, a geothermal resource consultant, will be speaking about the resources of five flash-type power plants in Nevada.

Nevada Petroleum and Geothermal Society Monthly Dinner Meeting:  Thursday September 4, 2014 (6:30 PM)
Where:  Ramada Reno Hotel, 1000 E 6th St, Reno, NV
Speaker:  Dick Benoit, geothermal resource consultant
Title:  Long-Term Performance of the Nevada Flash-Type Geothermal Projects

Abstract: Five flash-type power plants utilizing evaporative cooling have operated on different Nevada geothermal fields for periods of 21 to 28 years with varying degrees of success.  The Dixie Valley and Beowawe projects represent long-term successful projects that have operated at capacity factors generally above 85% and have power plants and resources well matched in size.  At Beowawe, the resource pressures and artesian flow rates have naturally increased to sustain output while temperatures have substantially declined.  At Dixie Valley, an augmented injection program was needed to stabilize resource pressures and flow rates while the temperatures have suffered modest declines.  The Bradys power plant has been the least successful project due to major reservoir cooling.  Bradys represents a case of a large liquid volume plant sited on a small resource.  The Desert Peak dual flash plant was replaced with a larger binary power plant after operating for 20 years and the project now consists of a medium-sized plant on a relatively small resource that has recently been declining in output.  The flash plant at Steamboat Hills is one of seven Steamboat plants located on a large reservoir.  It is now closely integrated with a binary power plant, and represents a successful case of a small plant located on a large resource.

About the speaker: Dick Benoit began working in the geothermal industry in Nov. 1973, after graduating from the University of Montana with a MS degree in Geology and has worked on many of the geothermal fields in Nevada during either the exploration phase or as a resource manager during production.  Dick is currently a geothermal resource consultant.
