Innovative Helicopter Inspections Enhance Power Line Safety in FirstEnergy's Service Areas

In an effort to ensure a reliable electricity supply during the hot summer months, FirstEnergy Corp. is deploying cutting-edge aerial inspection techniques across its service area. This initiative will utilize helicopters equipped with infrared and ultraviolet technology to monitor nearly 5,000 miles of high-voltage power lines. The proactive inspections aim to detect potential issues before they escalate, guaranteeing the uninterrupted flow of power to customers in six states.

These aerial patrols, operating at low altitudes of 25 to 35 mph, utilize specialized cameras that capture thermal images of electrical equipment. By viewing equipment through infrared and ultraviolet spectrums, the onboard technicians are able to identify overheating components or unusual voltage readings that might otherwise go undetected during regular visual inspections.

Mark Mroczynski, President of FirstEnergy Transmission, highlighted the significance of these inspections, stating, "The transmission system serves as the first defense against power outages by supplying electricity to substations and customers. This proactive work is vital as we strive to meet the growing energy demands of our society."

The infrared and ultraviolet inspections are carried out every four years in partnership with various FirstEnergy subsidiaries, ensuring that often invisible issues within transmission substations and power lines are addressed swiftly. Regular aerial patrols complement these in-depth inspections by identifying more apparent problems, such as vegetation encroachment, damaged apparatus, or bird nests affecting equipment.

The thermal imaging technology reveals temperature variations on a colorful scale, with bright colors indicating potential repair needs. The inspections can identify loose connections, signs of corrosion, and imbalanced loads. Similarly, ultraviolet technology is employed to detect electrical discharges along power lines, helping to pinpoint problems like rusted components or frayed insulators. By integrating both technologies, FirstEnergy achieves a robust inspection process capable of identifying a wide array of issues.

Currently, the aerial inspections are progressing across several regions:

- Ohio: 1,046 miles of lines inspected—approximately 64% completed.
- Pennsylvania: 2,220 miles—around 50% completed.
- New Jersey: 630 miles—about 42% completed.
- West Virginia and Maryland: 648 miles—20% completed.

Mroczynski noted the efficiency of helicopter inspections, stating, "They provide a vantage point that ground inspections simply cannot match, allowing us to cover extensive lengths of power lines in a single flight. However, ground inspections remain crucial in ensuring neighborhood lines and equipment are primed for the surge in electricity demand as air conditioning units operate full throttle during the summer."

This inspection operation supports FirstEnergy's Energize365 initiative, a comprehensive grid modernization program that reflects the company's commitment to addressing evolving energy needs. With planned investments of $28 billion from 2025 to 2029, the program endeavors to create an intelligent and resilient grid that not only meets current reliability standards but is also equipped for future challenges including electric vehicle demands and the adoption of renewable energy sources.

FirstEnergy, with its dedication to safety, reliability, and operational excellence, operates one of the largest investor-owned electric systems in the United States, serving millions of customers across several states. Its transmission subsidiaries manage approximately 24,000 miles of power lines connecting the Midwest and Mid-Atlantic regions, establishing the foundation for a secure and efficient electricity supply system.
