FAIRMONT, W.Va., Nov. 12, 2020 -- To help keep power flowing to customers during the cold winter season, Mon Power, a subsidiary of FirstEnergy Corp. (NYSE: FE), is preparing for winter in its West Virginia service area by conducting inspections and maintenance to help enhance system reliability.

Snow, ice and wind have the potential to damage equipment such as poles, wires and substations during the winter season, when demand for electricity is typically high. Mon Power is working to complete inspections and maintenance now to help preempt difficult repairs in harsh conditions and to keep power flowing to its customers in the months ahead.

"By actively preparing our power infrastructure and our fleet vehicles for potentially challenging winter weather, we will be better positioned to serve our customers and to ensure employee safety as the temperature drops," said Jim Myers, president of West Virginia operations for Mon Power.

Mon Power is inspecting substation components such as capacitor banks, transformers and oil- and gas-filled circuit breakers. Substation control buildings that house protective relays and remote monitoring and control equipment will be winterized and have their heating systems checked.

Substation electricians inspect batteries used to power relays and motors that sense faults on the network and operate switches to isolate those problems, helping to prevent or reduce service interruptions. Electricians view critical components through special thermal-imaging cameras to detect hot spots on equipment that could malfunction as customers crank up their heaters to combat the cold.

Company bucket trucks and other vehicles are also being inspected to help ensure safe operation during the winter season. Special emphasis is placed on the condition of tires and air braking systems, which can freeze up if moisture is present. In addition, snow removal equipment is being checked.

Helicopter patrols have been inspecting approximately 2,100 miles of transmission lines located in the Mon Power service area. The inspections are designed to look for damaged wire, broken cross arms, failed insulators and other hardware problems not visible from the ground. Any potential reliability issues identified during the inspection can then be addressed.

Tree trimming throughout the year also helps meet the rigors of winter operations by maintaining proper clearances around electrical systems and helping to protect against tree-related outages. Mon Power tree contractors have completed trimming along 4,600 circuit miles of electric lines and along nearly 400 miles of transmission lines this year.

Mon Power serves about 385,000 customers in 34 West Virginia counties. Follow Mon Power at, on Twitter @MonPowerWV, and on Facebook at
