"The HGP-A Generator Facility has been in nearly continuous operation for approximately 15 months. During this period well flow and power plant output have been maintained at 49,9000 kg/hr and 2.9 Mwe respectively. The quality and chemical composition of the steam from the well has been quite stable, whereas the salinity of the brines produced has increased steadily. The operational performance of the steam supply system has remained within specifications whereas maintenance difficulties with trip and control value hydraulics have been experienced. The hydrogen sulfide abatement systems for normal and standby conditions have proven to be quite effective, however, the operating costs of both systems have been found to be extremely high. Silica deposition rates within the brine control and disposal system have gradually increased since beginning operations and are presently considered to be the major impediments to continued operation of the facility. A major overhaul of the HGP-A Generator Facility is currently planned to take place in the near future."
