PPL’s (NYSE:PPL) PPL Electric Utilities will file a letter of notification with the Pennsylvania Public Utility Commission for the BuxMont-Elroy Transmission Line Upgrade Project, which involves rebuilding 8.4 miles of electric transmission line located in Franconia, Hatfield, and West Rockhill in Pennsylvania, a company spokesperson told TransmissionHub on Feb. 3.
The company expects project construction to start in November, and it would take about a year to complete the work on the line, which would operate at its current voltage of 69 kV, but would be designed for future 138-kV operation, he said.
The company estimates that it would cost about $13m for construction, he said.
There are five substations along the project route: the BuxMont, Telford, Franconia, Elroy and Hatfield substations, he said.
Discussing the need for the reliability project, the spokesperson said: “The line is about 45 years old. Some of the work we’ll be doing is replacing existing wood poles with steel monopoles and upgrading to higher capacity wires.”
