About the Project

Rochester Area Reliability Project

As part of our commitment to provide safe, reliable service to all of our customers, Rochester Gas and Electric (RG&E), in conjunction with its parent company AVANGRID, is making a significant investment to upgrade the electricity transmission system in the Rochester region. This project, known as the Rochester Area Reliability Project (RARP), is located in the towns of Chili, Gates and Henrietta, and in the City of Rochester. This project will provide additional power to support growing demand, increase reliability, and accommodate economic development in the Greater Rochester region.

Project Need and Benefits

The RG&E service area has safe and reliable electric delivery, but continued growth and contingency scenarios are putting pressure on our transmission system, the backbone of our electricity delivery system. The region requires access to additional sources of electricity supply to ensure safe and reliable electricity delivery is maintained.

Benefits to Our Region:

  • This capital investment includes the construction of a new substation in the Town of Henrietta, building (or rebuilding) transmission lines in the City of Rochester and the towns of Gates, Chili and Henrietta, and upgrades to three other existing substations.
  • The new and upgraded facilities will be capable of delivering additional energy to meet the region’s growing demands of the Rochester area, provide opportunity for expanded economic development, and improve reliability at a reasonable and relatively low cost.
  • Land use impacts are mitigated by the location of much of the project along existing transmission and railroad corridors.
  • The RARP will provide additional access to the neighboring 345-kV transmission system of the New York Power Authority (NYPA), coupled with upgrades to existing infrastructure.

Project Scope and Description

The overall project involves the construction, reconstruction, operation, and maintenance of approximately 27.6 miles of 345- and 115-kilovolt (kV) transmission lines, improvements to three existing substations in the Towns of Gates and Henrietta, and the City of Rochester; the construction of one new 345-kV/115-kV substation (Station 255) in the Town of Henrietta off East River Road; and upgrades within the fenced-in areas to existing substations in the Towns of Lewiston and Somerset in Niagara County.

The project scope includes:

  • Building a new 345-kilovolt (kV) substation (Station 255) near the NYPA transmission lines in the Town of Henrietta. 
  • Constructing a new 345-kV transmission line (Circuit 40) in the town of Henrietta.
  • Rebuilding/relocating 2.5 miles of existing Circuit 906 located in a railroad right of way in the Town of Chili.
  • Building a new 115-kV transmission line (Circuit 940) between the new Station 255 and our existing Station 418 in the vicinity of the Rochester Technology Park in Town of Gates.
  • Building a new 115-kV transmission line (Circuit 941) to connect the new Station 255 to our existing Station 23 on State Street in the City of Rochester, including a 1.1-mile section in the Town of Gates.
  • Improving equipment at existing Stations 418, 80 (located off of Lehigh Station Road in the Town of Henrietta) and 23.
  • Upgrading protection and communications systems at substations in the towns of Somerset, NY and Lewiston, NY. 

Most of the transmission lines will be above ground. Some portions of the new transmission lines, such as those near the airport, will be underground. Transmission lines will also be underground in some portions of the City of Rochester and the towns of Gates and Chili.

New York State Public Service Commission Case 11-T-0534

On September 29, 2011, RG&E filed an application with the New York State Public Service Commission (PSC) for approval of the Rochester Area Reliability Project under Article VII of Public Service Law, and on April 23, 2013, the PSC issued an order granting a Certificate of Environmental Compatibility for the RARP.

Subsequently, RG&E filed Environmental Management and Construction Plans (EM&CP) for the project, detailing the precise location of project facilities and precautions to ensure environmental compatibility. The project was divided into three Segments and an EM&CP has been prepared and submitted for each Segment. Please see the Milestones page for more information regarding the Segments.

EM&CP Segments I and II for the Project have been approved by the Public Service Commission and work has commenced on components included in those Segments. Work on Segment III will commence after approval by the Public Service Commission of the EM&CP Plan for Segment III of the project. Segment III includes the portion of the project between Station 80 in the town of Henrietta and transmission structure 39 on the Rochester and Southern Railroad right-of-way in the Town of Chili.
