An economic study of high-voltage transmission

THE RESULTS OF A STUDY, made in the light of present-day costs, on the economics of high-voltage transmission are presented. The study considers technical and economic aspects of two transmission patterns: straightaway transmission for distances of 25 to 300 miles, and extra-high-voltage transmission superimposed on an existing 115- or 230-kv system. The costs used in the study are averaged values at 1954–55 price levels and include energy and capacity charges for losses, as well as investment charges for terminal equipment and line construction.
