Was that substation fed off the grid? If so it was really not "backup" At the Salem facility they had several diesel generators and a huge bank of batteries for backup. The batteries would carry the load during the wind up cycle for the generators to come on line. They were 100% off grid. Not sure how much fuel they stored but I would suspect it was a few days worth. Do not believe that's it was meant to cover a 10 day ice storm outage!!
