Energy Cost Reduction Study of the Washington Metropolitan Area Transit Authority Metrorail System. Volume 1: Final Report

摘要

The Washington Metropolitan Area Transit Authority (WMATA) has established a program for reducing its overall energy costs. The objectives of this two-volume study were to classify the energy used by Metrorail into its primary end uses, and to identify those energy conservation strategies that have the highest potential for reducing energy costs. Although support energy (energy used in passenger stations, office buildings, and maintenance shops) is considered in this investigation, the primary emphasis is on traction energy (running the trains in revenue operation). The study involved analyzing the present energy costs, developing cost-effective energy conservation strategies, simulating the energy cost savings associated with these strategies, recommending the appropriate strategies for implementation and outlining a program for executing the recommendations.
