Determination of an Optimized Generator Expansion Pattern

A series of programs developed for a small-scale digital computer, such as the IBM (International Business Machines Corporation) 650, to optimize the selection of future additions to generating capacity are discussed. Two detailed programs show how the annual load-duration curve has been adapted to propagate a series of new generator-requirement curves. These curves, giving new generation needs by type for future years, are then available for use in other programs mentioned which develop real expansion patterns and all costs associated with them.
