Coal-Use Economics Methodology for Navy Bases. Phase I of Engineering Services for Coal Conversion Guidance

摘要

A methodology for calculating coal facility life cycle costs using commercial methods as well as Navy economic methods was prepared. The methodology permits calculation of life cycle present values, unit present values, levelized costs, and unit levelized costs for Navy financed/Navy operated ventures, third party financed/Navy operated ventures, and third party financed/third party operated (all private) ventures. The methodology also permits calculation of savings/investment ratios and payback periods for the three venture types. The attached user manual was prepared for a computer program that calculates coal-use project life cycle costs under both Navy and commercial economic assumptions. The manual describes computational methods, program input, program output, program execution, error processing, test procedures, and code structure. Appendices include output generated for four sample cases and a procedure to converge to a desired calculated quantity by a method of successive trials. (Author)
