Five Mile Road Station Project

The Five Mile Road Station Project, sponsored by National Grid, involves the construction and operation of a new 345-kV/115-kV transmission station; two new 345-kV transmission loops extending from the station to the National Grid-owned portion of the existing 345-kV Homer City-Stolle Road Line 37; and four new 115-kV loop connections, each about 650 feet long, to extend from the new station to two existing National Grid 115-kV transmission lines. The Homer City-Stolle Road Line 37 is a 200-mile, 345-kV line owned in part by NYSEG and National Grid and was placed into service in 1978. National Grid owns a 37.5-mile section. National Grid’s 65.5-mile, 115-kV Gardenville-Homer Hill Line 152 was built in 1967, and subsequently split in 2009, resulting in the addition of the Arcade-Homer Hill Line 167, which is 32.7 miles long, the company added. The project involves the rerouting of the Homer City-Stolle Road Line 37 into and out of the station by attaching to two 345-kV terminal structures. The two 115-kV lines, the Arcade-Homer Hill Line 167 and Gardenville-Homer Hill Line 152, will also be rerouted into the station, the company added. A total of six new transmission loops, two per line, will connect the existing transmission lines into the proposed station. No set schedule or cost has been released about the project and it is currently still under evaluation.
