SEPTA to Use Battery Storage Network
The Southeastern Pennsylvania Transportation Authority (SEPTA) will use a battery storage network funded, owned and operated by Constellation. The press release says that the 8.75 MW network will operate at seven SEPTA substations. Constellation is a subsidiary of Exelon Corp. The release says that Virdity also is working on the project.
The idea is to store and reuse energy generated by braking subway. The storage networks also will power drains in case of an outage. This is an expansion of a 1.8 MW pilot program that was completed in 2014. The addition will bring the total storage capacity to more than 10 MW.
Batteries are increasingly important to energy strategies. The Temecula (CA) Valley Unified School District is installing a system of solar panels and batteries, according to news initially reported in Inside Climate News.
