NYSEG Investing $8 Million to Upgrade Cobble Hill Substation in Western New York
Substation serves more than 3,700 customers in Boston, Colden, East Concord, and Glenwood
Upgrades will increase energy reliability in Erie County
LANCASTER, N.Y. — August 13, 2025 — New York State Electric & Gas (NYSEG) has begun upgrades to the Cobble Hill Substation which will improve reliability, resilience, and capacity for customers in the Towns of Boston, Colden, East Concord, and Glenwood. NYSEG is investing $8 million to upgrade this substation which serves approximately 3,700 customers in Western New York. This investment is part of Avangrid and NYSEG’s more than $7 billion in planned investments to modernize critical grid infrastructure through 2030 to meet the growing energy demands on homes and businesses and protect the community against severe weather events.
“This is a significant project for NYSEG,” said Marc Geaumont, president of NYSEG. “This substation will help ensure energy reliability for thousands of Western New Yorkers. Once this project is completed, it will also allow NYSEG to relocate a mobile substation to other areas in need.”
The substation is located on Hunn Road and is approximately 50 years old. This spring, NYSEG procured a 56 MVA transformer which will provide the energy load for the community. In addition to the transformer installation, NYSEG is adding other equipment that protect the transformer including a new oil containment system and lightning masts.
Energy reliability and resiliency remains at the forefront of NYSEG’s goals in New York. Since 2023, NYSEG has invested more than $378 million in projects which help keep the power on in homes and businesses. Last year, NYSEG and Rochester Gas and Electric (RG&E) also invested more than $90 million to trim and remove trees and other vegetation near power lines which pose a risk to the electric grid and customer service. The Companies’ commitment to upgrading and modernizing equipment to provide communities with the best service is a focal point of its operations. These investments will reinforce the grid in the face of increasingly severe storms and prepare it for the needs of the future.
“I am thrilled to see these critical improvements to the utility infrastructure that supports the Town of Boston and surrounding communities,” said Jason Keding, Town of Boston Supervisor. “NYSEG’s investment in the Cobble Hill Substation will enhance energy reliability and resiliency for our residents and businesses, ensuring that we’re better prepared for future demand and severe weather. This project represents a meaningful step forward in modernizing our grid and strengthening the foundation of our community’s growth and safety. We thank NYSEG for their continued partnership and commitment to the people of Boston and Erie County.”
“The Cobble Hill Substation has had its fair share of breakdowns in the past causing power outages within the Town of Colden,” said James P. DePasquale, Town of Colden Supervisor. “These upgrades will benefit the residents of Colden and surrounding communities for years to come. Unfortunately, the infrastructure has aged, and this project has become necessary. Money well spent!”
NYSEG estimates the Cobble Hill substation project will be complete and fully energized by the end of 2025.
