- Saft lithium-ion battery technology will supply megawatt level energy storage for the Southeastern Pennsylvania Transportation Authority (SEPTA) recycled energy and optimisation project.

Saft was selected by Viridity Energy to design, manufacture and commission the battery, which will also be one of the first dual purpose trackside energy storage systems in the US.

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

A strong pilot could lead to potential deployment at up to 32 SEPTA substations.
