The Red Rock Generation Facility is located at 695 E. Red Hills Pkwy and is owned and operated by the City of St. George Energy Services Department (SGESD). The plant is powered by two 10,000 horsepower Enterprise engines and each engine drives a 7,000 kilowatt generator. The facility began operation in 1986 and was used to shave peak loads. The engines are currently used to cover emergency load and support voltage as needed. Both engines are kept in a Hot Standby status to prevent damage during quick loading. Quick loading is a ten minute time frame from non-running to fully load. The air quality permit issued for the facility allows for it to be operated 1,500 megawatt hours annually.
This plant also houses the Dispatch and Control Center which includes the generation staff. Staff includes:
Four System Power Dispatch/Controllers
Three Generation Maintenance Technicians
Generation Superintendant
The Dispatchers/Controllers work a rotating 12 hour shift, 24 hours per day, 365 days per year to maintain load and voltage controls on St. George power grid.
