Tuesday's ice storm was so devastating to Southeastern Pennsylvania that Peco set an outage record for any winter storm.
As of midday Friday, the cumulative total had grown to about 715,000 homes and businesses that lost power at some point. For all seasons, only Superstorm Sandy, which hit in late October 2012, knocked more customers off the grid.
Let's be clear: In terms of human beings affected, the numbers are surely much higher. These are billing accounts, or addresses, not people. More than half of Peco's suburban customers lost power, so it's reasonable to estimate that perhaps 1.5 million of the 2.5 million residents of Chester, Delaware, Montgomery and Bucks County lost electricity, though Peco said it didn't track that data.
