Hampden County Reliability Project

Power & Utility > Substation

National Grid is an international electricity and gas company and one of the largest investor-owned energy companies in the world. They help provide energy to millions of customers across the northeastern U.S. in an efficient, reliable and safe manner.  As part of the project, a new substation will be built in Hampden, MA. 


Following completion of the substation, which is slated for late 2014, ten miles of an existing 69 kV transmission line in a National Grid right-of-way (ROW) will be replaced with a 115 kV transmission line. Taller steel poles (75-85 feet) will replace existing 45-55 foot wood poles so that the new higher voltage line is farther from trees and vegetation.


The Palmer substation will also be upgraded to accommodate the higher voltage of the new line. The transmission and substation upgrades are scheduled for completion during the summer of 2015.
