West Valley Generator Design and Replacement

Salas O’Brien was contracted to complete a full assessment and design for the County to provide a 20-year plan for the modernization of the emergency generator system. The emergency backup system generator provides critical support to the West Valley Detention Center (WVDC).

WVDC is a 3,347 bed facility providing 24-hour operation including inmate instruction programs, medical, dental, and mental health services. Given the nature of the WVDC, a highly reliable and modern emergency backup generator system was deemed essential.

During our review it was determined that the chiller plant would have greatly improved reliability if a high efficiency pony chiller was installed. This involved wiring the pony chiller into the new, triple-1000kW backup generator system and completing a comprehensive 20 year ease of maintenance plan, overall reduction of site energy costs and the integration of the generators with the existing TES system/chiller plant.
