Last year, the state of Pennsylvania awarded Viridity Energy funding through the 2010 Pennsylvania Energy Development Authority (PEDA) grant program for the "SEPTA Recycled Energy and Optimization Project." The project pairs the latest 21st century technologies and energy optimization practices with one of the country's oldest transportation systems, dating back to the deployment of electric trolleys in 1892, to capture and recycle energy created from the regenerative braking ability of trains and trolleys. The captured recycled energy improves power quality, produces energy savings and generates revenues.
The pilot project is targeted for commissioning by the end of 2011. Successful completion of the SEPTA project will demonstrate that energy storage can satisfy multiple value streams by accepting regenerative energy from train braking and while simultaneously providing a revenue source by participating in the PJM frequency regulation and economic energy market.
