As campuses evaluate the options for combined heat and power, newer technologies and economic analysis techniques have increased the complexity of any decision making process. This presentation analyzed the potential cost and savings for three possible cogeneration scenarios: a standard gas turbine generation cycle with a heat recovery boiler, a compound generation cycle with a gas turbine generator and backpressure steam turbine generation, and a compound generation cycle with a gas turbine generator and backpressure steam turbine generation with heat rejection. Each system represents a series of pros and cons for installation and operation, but an installation at the University of Missouri, Columbia helped us determine the ideal system construction to maximize payback and minimize the cost of electricity produced.
