Kinetic Energy Storage for Rapid Transit Applications

This paper describes the development of a kinetic energy wayside energy storage project with New York City Transit on the #7 Line near the Woodside 61
^st
Street station. The project is partially funded with a grant from the New York State Energy Research and Development Agency. The development approach is described. The modeling results, the estimated annual cost savings (~14%) and the impact on New York City Transits emissions of SO
