An Assessment of Energy Cost Trends on Electrical Equipment Selection for the Petrochemical Industry

The historical relationship of energy and equipment costs and their impact on decisionmaking are presented. From this base, projections of energy costs and equipment costs are presented and the decisionmaking is re-examined with regard to alternative solutions. Sensitivity analyses are developed around variations in forecasted data and in economic parameters. Electric motor and transformer examples are used to present salient points in the analysis.
