Economic evaluation of total energy: technical report

Technical Report · Thu Jul 12 04:00:00 EDT 1973

OSTI ID:6124556

This technical report discusses the analytical methodology used to develop the economic evaluation guidelines for comparing the capital and operating costs of total-energy systems (residential) with conventional energy systems. The discussion of methodology includes an identification of critical assumptions and a summary of intermediate results not shown in the separate guidelines document. Section II of the technical report serves as a central source of information required for economic evaluation of total-energy systems. The design methodology for both conventional and total-energy systems is presented in Section III. This discussion identifies the many energy systems synthesized and evaluated in the course of the study. Computer-simulation analysis was used to evaluate energy system designs and determine energy demand and consumption levels. In Section IV, the computer simulation analysis is described, and simulation results are presented. Results include energy demand and consumption data, waste-heat use levels, and total-energy fuel savings based on a comparison of optimum conventional and total-energy systems. Economic evaluation methodology and results are presented in Section V. The internal rate of return, based on capital costs and annual operating costs, was used to measure total-energy economic feasibility. The capital costs and operating-cost information required for the calculation of rate of return is represented. Final results, showing rate of return as a function of energy costs, climate, and project size, are included. A summary of the guidelines document is presented in Section VI. The appendices detail some aspects of the computer simulation and data collection. 33 references.
