Abstract

A prototype power plant could revolutionize on-site generation for
businesses. The Department of Energy and Oak Ridge National Labora-
tory teamed with Austin Energy, a municipal utility, to develop this
plant, called an integrated energy system. Burns & McDonnell devel-
oped, installed and is testing one of the largest systems in the nation to
use a new technology approach: use the waste heat exhaust from a natu-
ral-gas–fueled generator as the only fuel source for a chiller that provides
air conditioning. Recycling waste heat to power another generator or to
help run a chiller is not new. What is new is for a chiller of this size to
be fueled by waste heat alone—without any supplemental fuel. The
project’s chiller, called an absorption chiller, is capable of delivering 2,500
tons of chilled water. By design, the full waste heat output of the natural-
gas-powered 4.5-MW Solar turbine closely matches the chiller capacity.
Operation, which began in June 2004, should verify fuel efficiency of 70%
to 80% against 55% efficiency for the best central power plant technology
available today. Testing and verification of the skid-mounted design
should lead to adoption of this system in commercial and institutional
settings
