Reliability Upgrades

As part of our commitment to provide safe, reliable service to all our customers, Rochester Gas and Electric Corporation (RG&E), in conjunction with our parent company – AVANGRID, is updating the delivery system in our service areas. These upgrades comply with new electric transmission reliability requirements. While making investments to meet the community’s growing energy demands, we are working closely with our neighbors to ensure that all improvements are performed with minimal disruption to the environment and the communities we serve.

Project Purpose and Need            

To comply with more stringent reliability standards issued by the North American Electric Reliability Corporation (NERC), we are planning an upgrade of certain components of the electric delivery systems in the Town of Williamson. Specifically, we will be rebuilding Station 208 to increase its capacity, improve its asset conditions, and enhance the reliability requirements of the station for our valued RG&E customers.

This upgrade project will improve the overall resiliency of the entire system while simultaneously modernizing the substation’s technological components.

Project Scope

• Upgrading the existing transformer with a new, more efficient transformer to support the existing distribution circuit.
• Replacing the existing outdoor substation with a new indoor substation, with equipment housed inside pre-fabricated buildings.
• Rebuilding the existing substation to replace the existing air-insulated switchgear (AIS) with new 34.5 kV gas-insulated switchgear (GIS) technology and a new 15kV GIS class working at 12kV.
• Installing a new battery system and a new communication system.
• Utilizing the innovative solution of pre-fabricated buildings to house the upgraded equipment. Components are pre-tested, pre-assembled, and reduce installation time and cost.
• Creating a new redundant connection to increase the reliability of the station’s service, since the new station will be providing a critical redundancy connection.
• Installing new perimeter contingency lighting for potential urgent or afterhours work.
• Installing a mobile substation unit to provide an alternate power source during construction to ensure uninterrupted service.
