Why Pennsylvania Needs Backup Power
Pennsylvania's heavy tree canopy and rural distribution lines make the grid vulnerable to ice storms and high winds. PECO and PPL serve millions across the state, and winter outages lasting multiple days are not uncommon.
The February 2024 ice storm left over 400,000 Pennsylvania customers without power. Winter storms regularly bring multi-day outages, especially in rural areas. Power in Pennsylvania is served by PECO (Philadelphia), PPL Electric, Duquesne Light (Pittsburgh), FirstEnergy. According to the Pennsylvania State Electricity Profile, the state averages 2.5 outages per year with a mean duration of 7 hours per event.
