Powerful Summer Storms Cause Distribution and Transmission Outages

Powerful summer storms that blew across the PJM Interconnection footprint Tuesday afternoon and evening caused approximately 750,000 customer outages. The storms moved from Virginia to New Jersey. Most of the outages occurred in Southern New Jersey and Southeast Pennsylvania.

As of noon on Wednesday, there were still more than 400,000 customer outages in the PJM footprint, mostly in the Mid-Atlantic region.

The effects of the storm caused several transmission lines in New Jersey to be taken out of service automatically or manually to protect the power supply system. PJM members in the affected areas began to restore their customers’ service as quickly as possible.

Parts of southern New Jersey had dozens of transmission lines go out of service in brief time periods throughout the storm.
