Metropolitan Philadelphia’s transit will be using energy from train brakes to assist in powering the transit system and adding to the region’s electricity grid.

As generator-equipped subway trains apply their brakes, the energy that is created will be sent to a battery for storage. The stored power can then be used to power accelerating trains or sold to the grid. The energy from braking trains could cut the subway’s electricity bills by as much as 40 percent.
