JEA, located in Jacksonville, Florida, is the largest community-owned electric utility company in Florida, serving over 478,000 electric, 357,000 water and 279,000 sewer customers. JEA’s District Energy System (DES) provides chilled water to customers for air-conditioning. The facilities for the chilled water business consist of chilled water plants and underground piping to distribute the chilled water to buildings located within the districts served by the plants. The Springfield Plant, built in 2005, serves the University of Florida College of Medicine, the Proton Beam Facility, and the Shands Healthcare campus. It currently contains six 1,500-ton chillers and a 6,100-ton cooling tower with chiller demand ranging from one to four chillers at any time.
Our contract consisted of the installation of a new 4MW (60Hz, 4160V) emergency generator as part of the resiliency upgrade of the Springfield Chilled Water Plant. Work included general site preparation, installation of a separate standalone fuel tank, concrete pads, switchgear and high-power buried conduit/cable in concrete encased ductbank. All new equipment controls were integrated into the existing energy management controls system.
The generator installed was a C175-20 Diesel engine rated at 3,900kW Standby, 4160V, 0.8PF, 3 Phase, 60 HZ, 4 Wire, EPA Certified for Stationary Use Tier 2. An aluminum, sound attenuated enclosure was constructed to house the generator. A 10,000 gallon subbase fuel tank and 10,000 gallon above ground fuel tank was installed with 7-1/2 gallon spill containment.
