The Economics of Steam Electric Generation
MetadataShow full item record
The economics of combining steam and electric generation for companies requiring both steam and electric services develop a challenge which few engineers and economists can realize. This paper outlines the general approach to this challenge and the procedure for reaching an equitable solution. The approach uses a system of programs which meet both present and future requirements. Each program has different operating costs and capital investments spread over an extended period of time. Simple load growth procedures establish the future requirements and non computerized construction schedules guide the procedure to completion. Capital expenditures, by this approach, are established and are then combined with operating costs. The present worth system is then used to evaluate each program. This system is also adjusted to show the effect of inflation and other variables affecting the evaluation. This procedure allows each system to be summarized, with or without inflation. to assist management in reaching an equitable solution to the problem.
