P art-Load Cogeneration Technology Meets Chilled Water and Steam Requirements

Abstract

Louisiana State University's Energy Savings Performance Con-
tract with CESfWay was a groundbreaking project that applied part-
load cogeneration technology to a large university campus to meet
chilled water and steam requirements for expansion needs. Simulta-
neously , the project provided these utilities at no additional out of
pocket cost to the institution by using the innovative financing
mechanism of performance contracting, in which project savings pa y
for the investment.
In addition , the work is performed via a cogeneration s ystem
operating most of the year at part-load. This mechanical cogeneration
project could also be termed a "thermal cogeneration" project, as it
pro vides a dual thermal benefit from a single input energy source.
Not only did the project achieve the projected energ y sa vings,
but the sa vings proved to be so dependable that the Universit y opted
for an early bu yout of the project from CES/Way in 1994, after onl y
about two years of documented savings.
