Circuit 813 Project

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            

Aging infrastructure, recent outages, and redundancy limitations have highlighted the need to install a new 3.5-mile line referred to as Circuit 813. This transmission line goes through the Towns of Brighton, Penfield and Pittsford, the Village of East Rochester, and the City of Rochester.


The first phase of construction in this large-scale overarching project will be focused on the portion of the line that runs from Station 42, located on Yarmouth Road in the City of Rochester, to Station 62 on North Washington Street in the Village of East Rochester. RG&E has had several outages on adjacent circuits in recent years impacting both customers and local businesses.

The comprehensive circuit spans the region from East Rochester to Brighton. The red line on the map indicates the areas impacted by the upgrade project. This infrastructure enhancement will improve the overall resiliency of the entire system while simultaneously modernizing the circuit’s components.
