Abstract

The University of Texas at Austin’s combined heat and power(CHP) plant has provided reliable, ef ficient, and cost effective utilitiessince its inception in 1928. This natural-gas- fired plant currently canproduce up to 110 MW of electricity at 12-kV and 4.16-kV, 1.1 millionlbs/hr of steam at 425 psi, 700°F, and 40,800 tons of chilled water usingelectric and steam turbine driven chillers. The system also provides thecampus compressed air and about 9 million gallons per year of demin-eralized water for building and laboratory use. The system supports acampus of about 16 million square feet via underground tunnels andelectrical duct banks.
