Ginna Retirement Transmission Alternative Project
WHAT IS THE GINNA RETIREMENT TRANSMISSION ALTERNATIVE (GRTA)?
The GRTA is a long-term solution that would strengthen the RG&E electric transmission system to meet all system reliability requirements with or without supply from the Ginna nuclear power plant. The GRTA will enable more power to be delivered to RG&E’s system from the New York Power Authority high-voltage, cross-state transmission facilities. The project, which will cost
approximately $150 million, includes:
- Completing major upgrades to transformers and other equipment at two bulk-power substations.
- Increasing the capacity of nearly 15.5 miles of three 34,500-volt underground transmission lines.
- Increasing the capacity of about 1.5 miles of 11,500-volt underground transmission lines.
- Currently, RG&E’s electrical transmission and distribution system meets all reliability standards for the delivery of power to our customers. However, the system would not meet reliability standards under certain conditions if Exelon Corporation retires the Ginna nuclear power plant.
- Ginna’s output currently equates to about half of the electric load in the Rochester region.
- To ensure Ginna continues to operate in the short term, RG&E negotiated a Reliability Support Services Agreement (RSSA) with Exelon.
- Energizing the GRTA would allow Exelon to retire the Ginna plant, should Excelon make that decision.
CONSTRUCTION TIMELINE AND ANTICIPATED SCHEDULE
- Work on the substations began early in 2016. The start of construction on the electric transmission lines is anticipated to begin in late spring 2016.
- We expect the upgraded facilities that comprise the GRTA to be in service in 2017.
GRTA IMPACT ON ELECTRICITY DELIVERY RATES
- Historically, the costs for infrastructure improvements and investments in system safety and reliability have been included in our rates.
- We believe the project will not have a major impact on electricity rates particularly compared to the impact of the RSSA.
- Construction will have minimal impact on the community because all transmission line upgrades will occur underground, in our existing rights of way, and (for the most part) in existing conduits. We will build a number of new conduits in a few isolated areas. More extensive construction, however, is necessary along Atlantic and University Avenues and Culver Road.

- We will make all substation improvements inside the existing property boundaries.
- We will be able to execute most of the transmission line upgrades by pulling new, higher-capacity cables through the conduits from manhole to manhole.
- We expect any traffic/road disruptions caused by the work would be few in number and duration.
- We will carefully schedule our work to avoid disrupting morning and evening commuter travel.
- The project will also involve major upgrades to our bulk- power substations: Station 80 in Henrietta and Station 122 in Perinton.
- We also will perform some minor upgrades to Station 7 in Greece and Stations 1, 3/137, 29, 38 and 42 in the City of Rochester.
