Pennsylvania Electric Co. plans to upgrade about 2,300 wooden utility poles in 2017 as part of its annual inspection program aimed at enhancing service reliability for its customers.

Inspections started in January and will continue through summer, with the remaining pole replacements and repairs scheduled to be completed during the fall. The FirstEnergy Corp. subsidiary will spend $3 million to examine approximately 42,000 poles in 2017, according to a May 30 release.

All wooden poles within the 31-county Pennsylvania Electric service territory are inspected on a 12-year cycle.
