Viridity Energy announced that it selected Saft and Envitech Energy Inc. in support of its recycled energy and optimization project with the Southeastern Pennsylvania Transportation Authority (SEPTA).

The SEPTA project includes the installation of an advanced battery storage system by Viridity Energy that will capture and deploy power from the trains' regenerative braking. Viridity Energy will optimize SEPTA's energy storage system at one of its substations to use the excess stored energy as a resource that provides energy service and reliability benefits to the power grid via participation in PJM's wholesale energy market.

"We are pleased to be working with Viridity, Saft and other partners on this exciting energy storage project," said Andrew Gillespie, SEPTA's chief engineering officer for power. "We can't wait to see the how Saft's experience with onboard train applications and trackside power management will benefit the project."
