USA, Pennsylvania: FirstEnergy Corp. has completed construction of a new substation and transmission line in Armstrong County to help enhance service reliability for West Penn Power customers in Allegheny, Armstrong, Butler and Westmoreland counties.
"These infrastructure investments in Armstrong County will help us continue to provide reliable service to our customers." said David W. McDonald, president of West Penn Power. "In addition to benefiting West Penn Power customers, this project also will help enhance the regional transmission system."
As part of the $31 million project, a new 345 kV substation was constructed next to FirstEnergy's deactivated Armstrong Power Plant. The major component of the construction process was the installation of a large transformer that converts the power from 345 kV to 138 kV as it moves along the transmission system.
The new substation equipment and line are owned by Trans-Allegheny Interstate Line Company, a FirstEnergy transmission affiliate.
