The Energy Optimization project is designed to capture energy from rail cars through a regenerative braking process and then utilize the energy for accelerating trains, and to generate revenue through demand-side participation in power markets.

Saft will provide one Intensium Max 20P Li-ion megawatt energy storage system to capture train braking energy and then discharge it back to the third rail (power rail) to power trains leaving the station. The system will provide regenerative braking charge acceptance for SEPTA trains and power discharge back to the station to support rail traffic while simultaneously participating in the PJM Interconnection market for frequency regulation.
