The Southeastern Pennsylvania Transportation Authority is about to test a new system for more effectively capturing regenerative energy from trains.

Electricity gathered via the Recycled Energy and Optimization project will be used for accelerating trains, “and to generate revenue through demand-side participation in power markets [with] significant economic and environmental benefits.”

A ribbon cutting ceremony will be held this Wednesday, June 27, at the Letterly Substation on SEPTA’s Market-Frankford line – its busiest – in Philadelphia.

The pilot program utilizes cutting-edge technology from several project partners. Viridity Energy implemented its VPower software optimization and market integration system. Saft, leader in high technology batteries, provided the Intensium Max20 brand lithium ion megawatt energy storage system.

Envitech Energy, a member of the ABB group, deployed its Power Control System integration technology.

“Successful completion of the SEPTA project will demonstrate that energy storage can satisfy multiple value streams by accepting regenerative energy from train braking while simultaneously providing a revenue source,” the partners say.

“SEPTA will capture and productively use electric power that would otherwise be wasted; generate significant new revenues through electric market participation; increase operational efficiency; support the achievement of sustainability goals; and enhance the reliability of the electric grid,” Viridity says.
