Report on the October 1987 Hawaiian HGP-A Power Plant Overhaul and Reservoir Production Data

Abstract

The Research Corporation of the University of Hawaii (RCUH) completed the third overhaul of the HGP-A power plant during October and November 197. The 3 MW power plant was developed jointly y the Federal government and the State of Hawaii and began operation in 1982 in order to demonstrate the electrical production ability of the geothermal resources. This paper presents the overhaul details, the investigative results and the history of the operational parameters. The increase in power output after the overhaul indicates that the HGP-A well has minimal production drawdown. However, the corrosive deterioration of the plant indicates that any new plant design must be practical, use property materials and be easily maintainable.
