PECO Delivers Reliable Service Through Historic Summer Storm and Excessive Summer Heat

Infrastructure investments, system preparations, and dedicated utility crews help region weather summer challenges

PHILADELPHIA (October 21, 2025) - The summer of 2025 marked a pivotal moment for utility reliability in southeastern Pennsylvania, as PECO faced several stretches of excessive heat and one of the company's worst storms in its history. Despite these challenges and thanks to strategic infrastructure investments, advanced preparation, and the tireless efforts of its workforce, customers experienced fewer interruptions on days when temperatures soared above 90 degrees with less equipment issues than previous summers, proving that the company's reliability and resiliency enhancements are paying off.

Throughout the next five years, PECO is investing nearly $10 billion across its electric grid and natural gas infrastructure. As part of these modernization efforts, the company continues to make upgrades to its systems to better withstand extreme weather events and reduce the frequency and duration of power outages. This work includes proactive vegetation management, replacing aging transmission lines, and retiring or upgrading outdated substations and equipment.

Part of these improvements includes the continued installation and maintenance of equipment known as reclosers, that can automatically restore service or isolate storm damage.

• This summer, reclosers across the system prevented approximately 400,000 outages.

The company also utilizes smart meters, which support restoration activities during storm events.

• Throughout the summer, smart meters helped PECO avoid dispatching crews unnecessarily 14,814 times by confirming customer restoration status, improving reliability, and reducing costs through faster, more efficient outage response.

A significant test for the company came in late June, with intense heat and the company's 13th most impactful storm. As a result, 367,000 customers in the region were left without power. Despite the storms damage and severity, 50 percent of customer outages were restored within 24 hours, and all customers were fully restored by June 23, just four days after the event began on the evening of June 19.

"We are so proud of every employee who responded to the call to serve our customers this summer," said Nicole LeVine, PECO senior vice president and COO. "Their critical work throughout the year to strengthen our infrastructure made it possible to quickly restore service to every customer impacted by the significant storm we experienced in June."

In terms of infrastructure repairs, PECO replaced 10,600 fuses, 1,300 cross arms, and 280 transformers. These replacements were essential to restoring service and strengthening the grid against future disruptions. Crews repaired 610 miles of wires and cable throughout the service area. This extensive work not only helped restore power but highlights the dedication of PECO utility workers across all levels of the company.

Vegetation management played a critical role in the restoration process as well. Crews completed 1,628 vegetation assignments, which included trimming or removing fallen trees, branches, and limbs that had caused outages across the region. When the severe weather hit in June, employees worked extensively to help remove trees and other debris following the storm. PECO continues to invest in tree trimming and removal, investing $58 million through 2025.

The storm in June was compounded by the heat with multiple days of 90 degrees and above. Residents across the region experienced record-breaking heat in June. Temperatures rose as high as 100 degrees, with a heat index of up to 110 in the Philadelphia area from June 23 through June 25. This summer has shown that PECO crews are prepared and ready to respond to any challenge. As the fall season sets in and temperatures start to dip, PECO remains focused on ensuring its natural gas and electric systems are fully prepared to meet customers' energy needs throughout the winter months ahead.
