20-kW Solar Photovoltaic Flat-Panel Power System for an Uninterruptible Power-System Load in El Paso, Texas. Phase Ii. System Fabrication. Final Report October 1, 1979-May 31, 1981
The system plans, construction, integration and test, and performance evaluation are discussed for the photovoltaic power supply at the Newman Power Station in El Paso, Texas. The system consists of 64 parallel-connected panels, each panel containing nine series-connected photovoltaic modules. The system is connected, through power monitoring equipment, to an existing DC bus that supplies uninterruptible power to a computer that controls the power generating equipment. The site is described and possible environmental hazards are assessed. Site preparation and the installation of the photovoltaic panels, electrical cabling, and instrumentation subsystems are described. System testing includes initial system checkout, module performance test, control system test. A training program for operators and maintenance personnel is briefly described, including visual aids. Performance data collection and analysis are described, and actual data are compared with a computer simulation. System drawings are included. (LEW)

Geothermal Development Plan: Maricopa County
Maricopa county is the area of Arizona receiving top priority since it contains over half of the state's population. The county is located entirely within the Basin and Range physiographic region in which geothermal resources are known to occur. Several approaches were taken to match potential users to geothermal resources. One approach involved matching some of the largest facilities in the county to nearby geothermal resources. Other approaches involved identifying industrial processes whose heat requirements are less than the average assessed geothermal reservoir temperature of 110/sup 0/C (230/sup 0/F). Since many of the industries are located on or near geothermal resources, geothermal energy potentially could be adapted to many industrial processes.

Geothermal Development Plan: Cochise-Santa Cruz Counties
A total of five hot springs and 25 thermal wells are located within the combined counties. The water discharged from these hot springs and wells may be suitable for applications such as process heat and space heating and cooling. Within Cochise county there are two large firms which are capable of using 70/sup 0/C (158/sup 0/F) geothermal water for their process heat requirements but the potential use of geothermal energy in Santa Cruz county is limited due to the absence of industry within the county. The amount of geothermal energy on line as a function of time under both private and city-owned utility development is also predicted using a computer simulation model.

Geothermal Development Plan: Pima County
Pima County is located entirely within the Basin and Range physiographic province in which geothermal resources are known to occur. Continued growth as indicated by such factors as population growth, employment and income will require large amounts of energy. It is believed that geothermal energy could provide some of the energy that will be needed. Potential users of geothermal energy within the county are identified.
