Book Description
The proposed design, construction, and operation of a commercial-scale (45 MWe net) binary-cycle geothermal demonstration power plant are described using the liquid-dominated geothermal resource at Heber, Imperial County, California. The following are included in the environmental assessment: a description of the affected environment, potential environmental consequences of the proposed action, mitigation measures and monitoring plans, possible future developmental activities at the Heber anomaly, and regulations and permit requirements. (MHR).

Book Description
The objectives for the Heber Demonstration Project are to: Design, construct, and operate the world's first commercial-size, binary-cycle, power plant by mid-1984; Confirm the binary-cycle as the best overall electric energy conversion technology for moderate temperature (300-400 F) hydrothermal resources; Demonstrate the environmental acceptability of large-scale, binary-cycle technology; Provide the Department of Energy with the component and system performance data necessary to stimulate nationwide geothermal development; and Establish an alternative energy source for electric power generation and to help reduce U.S. dependence on uncertain supplies of foreign oil.

Book Description
San Diego Gas and Electric (SDG and E) believes that the binary-cycle offers an improved method of converting moderate temperature geothermal resources into electric power. The process, shown schematically in figure 1-1, has significant advantages over existing methods of geothermal power generation. The advantages of the binary process are that greater amounts of power can be generated from a given resource, fewer wells are needed to support a given power output, and the binary-cycle is expected to be more economical than the flash process for this type of resource. Another advantage is that the binary-cycle is a closed process and thus enhances environmental acceptability. In addition, this process is applicable to a larger range of the nations geothermal reservoirs. It is estimated that 80% of the nation's hydrothermal resources can be classified as moderate temperature (300 to 410 F) resources. The flash process, commonly used to convert high temperature geothermal resources to electric power, is technically feasible for moderate temperature resources. However, when compared to the binary process for moderate temperature applications, the flash process conversion efficiency is lower, environmental impacts may require abatement, and power production costs may not be commercially competitive.

Book Description
The Heber Binary Project had its beginning in studies performed for the Electric Power Research Institute (EPRI), which identified the need for commercial scale (50 Mw or larger) demonstration of the binary cycle technology. In late 1980, SDG & E and the Department of Energy (DOE) signed a Cooperative Agreement calling for DOE to share in 50 percent of the Project costs. Similarly, SDG & E signed Project participation agreements with EPRI, the Imperial Irrigation District, California Department of Water Resources, and Southern California Edison Company, which provided the remaining 50 percent of the required funding. In 1982, the State of California also joined the Project. The objectives of the Heber Binary Project are to demonstrate the potential of moderate-temperature (below 410 F) geothermal energy to produce economic electric power with binary cycle conversion technology, and to establish schedule, cost and equipment performance, reservoir performance, and the environmental acceptability of such plants. The plant will be the first large-scale power generating facility in the world utilizing the binary conversion process, and it is expected that information resulting from this Project will be applicable to a wide range of moderate-temperature hydrothermal reservoirs, which represent 80 percent of geothermal resources in the United States. To accomplish the plant engineering, design, and equipment procurement, SDG & E has hired Fluor Engineers, Inc., Power Division, of Irvine, California. In early 1982, SDG & E contracted for construction management services with Dravo Constructors, Inc. (DCI) of New York. DCI is responsible for casting the Fluor design into construction packages, letting the construction contracts, and overseeing the construction in the field.

Book Description
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°F, 182°C) fluid from the Heber reservoir in southern California.
