Annual Load Relief Map, Peak Load and Load Factor Analysis

Description of the annual load relief map which is a device for visualizing the entire yearly load of central stations. Review of load characteristics, as exemplified by the annual load relief map. Notes on daylight saving relative to the decreasing of peak load, and improvement in load factor. Analysis of load factors as applied to ``base´´ and ``top´´ loads demonstrating the large amount of idle capacity peculiar to central stations. Annual load relief map valuable in the study and exemplification of all matters having to do with central station loads.
