Thomson-Vogtle
Fact Sheet

Building for the Future

Two new nuclear operating units are under construction at Plant Vogtle nuclear operating plant, near Augusta, Ga.

  • Both units will be operational by 2020. Unit 3 will come on line in 2019 and Unit 4 in 2020.
  • Each unit will produce 1,100 MW of electricity for a total increase of 2,200 MW.
  • One MW of electricity will serve 800 to 1,000 households. Upon completion of the new units, Plant Vogtle will produce enough power to serve 1.4 million homes.
  • Building the two new nuclear units will help meet the electrical needs of Georgia Power customers in 2019 and beyond.
  • To support the additional generation from the new units, Georgia Power's infrastructure must be upgraded. The existing transmission system is not adequate to reliably transport the additional electrical power from Plant Vogtle to our customers.
  • The Thomson-Vogtle 500 kV transmission line must be built to add the necessary transmission infrastructure to support the two new nuclear units.
  • The line route is 55 miles long and begins at the Thomson Primary substation southeast of Thomson, Ga. (McDuffie County) and ends at Plant Vogtle in Waynesboro, Ga. (Burke County).
  • The route runs through four counties: Burke, Jefferson, Warren, and McDuffie.

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.
