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.
MAIT will rebuild approximately 13 miles of transmission line in Adams County, Pennsylvania. The project will also require MAIT to rebuild 2 miles of a 115-kV transmission line in Adams County, north of the Lincoln Substation in Straban Township.
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.
