Combined heat and power (CHP) is an efficient and clean
approach to generating electricity and useful thermal
energy from a single source of fuel. CHP has been in use
in the Unites States for more than 100 years and currently
represents approximately 8% of all generating capacity or
82,000 MW, located at over 3,600 industrial and commercial
facilities. Centralized electric power generation in the United
States typically converts 34–35% of the fuel consumed into
electricity, with the remainder of the energy lost in the form
of waste heat. Installing a CHP system that uses thermal
energy and electricity can result in 60–85% of the fuel energy
being utilized. Breweries are great potential candidates for
implementing CHP because electricity, steam, and hot water
are all requirements of the brewing and packaging processes.
Although there are several U.S. breweries that have installed
CHP systems, the majority have not. We believe there is great
opportunity for additional U.S. breweries to cost effectively
implement CHP projects. Successful execution of a CHP
project requires financial, legal, engineering, construction, and
environmental expertise. The case study presented describes
the process of developing a 210 kW CHP project from concept
though start-up. The steps described in the study are applicable
to most CHP projects no matter the size.
