Thomson-Vogtle Transmission Line

Building for the Future

The Thomson-Vogtle 500 kV transmission line is being built to add the necessary transmission infrastructure to support the two new nuclear units. The line route is 55 miles long and begins at Plant Vogtle in Waynesboro, Ga. (Burke County) and ends at the Thomson Primary substation, southeast of Thomson, Ga. (McDuffie County). The route runs through Burke, Jefferson, Warren and McDuffie counties and existing transmission line corridors were utilized over approximately 13 miles of the line route.

The transmission line will be in service by 2018 to support the new Vogtle units, which will continue to provide our customers with reliable service for many years to come.

Fact Sheet

In selecting the line route, a location committee comprised of Georgia Power employees representing various functions in the company considered many factors including, but not limited to:

• Potential impact to the community.
• Existing land uses in the geographic area where the line route is located.
• Existing environmental conditions in the area.
• Existing corridors.
• Engineering practices and costs related to the construction, operation and maintenance of the transmission line.
• Accessibility.
• System reliability.
• Existing transmission line corridors were utilized over approximately 13 miles of the line route.
• The transmission line will be in service by 2018.
• The electric bills of area residents and other ratepayers will not immediately increase as a result of this project.
• These costs are a part of Georgia Power's normal capital improvement budget and are eventually added into the overall rate base.
• This project will not be included in the rate base until it actually goes into service. Even then, rates will only change when the Georgia Public Service Commission approves a base rate case.
• Georgia Power Transmission Construction may build up to 10 miles of the line out from the plant.
• The bulk of the line will be constructed by a line construction contractor.
• We will use a competitive bid process to select the company.
