Transmission and Distribution Cost Data for Use in Community Total Energy System Analysis with Fort Knox, Kentucky as an Example.

Abstract : The purpose of this study is to estimate the capital costs of an electrical Transmission and Distribution T and D system. These costs actually refer to the marginal costs of modifying an existing T and D system to meet the requirements of a future planned Total Energy System which would be of a different capacity than that currently in place. The amount of equipment required for a given T and D system configuration is first determined. Then unit costs are derived and applied to the equipment needs, thus generating total T and D system costs. Marginal costs of the modified T and D system can then be computed. It is found that marginal T and D costs are not insignificant when analyzing the economics of power generation, especially in the construction of electric-intensive Total Energy Systems.
