CJ Leonard of Abington Township recently told 6ABC Action News that her PECO bill jumped from $110 to about $500.

Hundreds of residents in the Philly metro region reported increases of varying degrees as well. Action News is looking into the matter, and said that it will follow up with more information.

For now, Greg Smore of PECO told Action News that electricity prices have increased roughly 15% since September, which translates to $8-10 more per month on average for customers. Geopolitical issues and colder weather are partly responsible for the rise as well, Action News reported.
