I know, I'm excited too!
People give the Nutter administration crap, but sensible, lawful things are happening on his watch. That's not saying this SEPTA thing is something he can take credit for, but it is under his administration.
What is it? As revealed in this Technology Review article, SEPTA's installing batteries at a subway substation to cash in on regenerative braking:
A massive battery installed at one of the authority's substations will store electricity generated by the braking systems on trains (as the trains slow down the wheels drive generators). The battery will help trains accelerate, cutting power consumption, and will also provide extra power that can be sold back to the regional power grid. The pilot project, which involves one of 38 substations in the transit system, is expected to bring in $500,000 a year. This figure would multiply if the batteries are installed at other substations.
Philadelphia, there's hope for us yet.
