SEPTA Plans to Use Brake Energy

from the inbox:

SEPTA, Constellation, and Viridity Energy are announcing plans to install an 8.75-megawatt battery storage network that will capture and reuse energy generated by braking subway cars.

 An expansion of SEPTA’s 1.8-megawatt battery storage pilot, the 8.75 MW network will help SEPTA reduce operating costs and ensure energy resiliency while providing a clean power source to support the stability of the electrical grid. 

 When complete, the network will be one of the nation’s largest customer-sited battery storage systems -- the first commercially-deployed for a transit operation – and serve as a model for using battery storage assets to supply power in congested parts of the grid.
