Carroll-Hunterstown Improvements Project

The project consists of rebuilding approximately 24 miles of the existing transmission line between the Hunterstown Substation in Adams County, Pennsylvania, and the Carroll Substation in Carroll County, Maryland.

Potomac Edison will rebuild approximately 11 miles of transmission line in Carroll County, Maryland, and expand the Carroll Substation for upgrades related to the rebuilt line.

The project will utilize existing transmission rights-of-way for the work, minimizing environmental and community impacts. It will enhance transmission system reliability, accommodate growing demand for electricity by residential and commercial customers, and facilitate the connection of renewable energy sources.
