Santa Clara is a small but growing community near St. George in southern Utah. The city’s population grew more than 30 percent from 2000 to 2006. This was due to a booming economy driven by a favorable climate, affordable housing market and proximity to growing metropolitan areas such as Salt Lake City and Las Vegas. Such dramatic growth resulted in a strain on power resources felt by the municipality, businesses and residents.
Santa Clara contracted Wheeler Power Systems to handle the powerhouse design and build. The Santa Clara facility was built out to accommodate immediate delivery of two G3520C natural gas generator sets. The generator sets, rated at 2,055 ekW at 1,800 rpm, operate together with paralleling switchgear rated at 12,470 V. The power is then increased to 69,000 V by an outdoor transformer before connecting to the distribution lines.
