Over twenty (20) cogeneration feasibility studies have been completed since 1984 of potential sites at state agencies within Texas. The Austin State Hospital was one facility which appeared to be technically and economically attractive. The original analysis in 1985 recommended a 1.0 MW gas turbine cogeneration system be installed at the hospital site. Austin State Hospital staff were in favor of the project and a consulting engineering firm was hired to complete a more thorough study. Their results confirmed the economic feasiblity and also recommended a 1.0 MW gas turbine cogeneration system. The Austin State Hospital filed for approval of the cogeneration system which was granted in 1989. They then sought bids for the project and in 1990 awarded the project. Construction of the system is underway. This paper includes descriptions of the Austin State Hospital facility, of the computer programs used for the evaluations, of the major inputs and assumptions for the computer programs, and of the method of analysis. This paper then documents the results of the several studies, describes the selection of the final cogeneration system, and discusses the financing of the selected system.
