An assessment is presented of the reliability and availability of the Heber Geothermal Binary Demonstration Plant on the basis of preliminary design information. It also identifies and ranks components of the plant in order of their criticality to system operation and their contribution to system unavailability. The sensitivity of the various components to uncertainties of data and the potential for reliability growth are also examined. The assessment results were obtained through the adaptation and application of an existing reliability and availability methodology to the Heber plant design. These preliminary assessments were made to assist (1) in evaluating design alternatives for the plant and (2) in demonstrating that the closed-loop, multiple-fluid, binary cycle geothermal concept is competitive with the more conventional flashed steam cycle technology. The Heber Geothermal Binary Demonstration Plant Project is a cooperative effort directed toward accelerating geothermal development for power generation and establishing the binary cycle technology as a proven alternative to the flashed steam cycle for moderate temperature hydrothermal resources. The binary power plant would have a capacity of 45 MW/sub e/ net and would derive its energy from the low salinity (14,000 ppM), moderate temperature (360/sup 0/F, 182/sup 0/C) fluid from the Heber reservoir in southern California.
