About the Project
Georgia Power is planning the Hills Bridge–Speedway 500 kV Transmission Project in Henry and Clayton counties to support the electric needs of a data center customer that requires new transmission infrastructure, while also strengthening the local electric grid in a rapidly growing area. The project currently includes construction of three transmission lines, one 500 kV line and two 230 kV lines, as well as two new substations, Hills Bridge 500/230 kV Substation and Speedway 230 kV Substation. Together, these improvements will add capacity, enhance reliability for homes and businesses, and position the region to support continued growth and evolving energy needs.
What’s included in the project?
Certain components of the project are being evaluated to support customer-specific needs, while all improvements contribute to strengthening the overall transmission system. Some elements are in the planning phase, and details may be refined as the project progresses.
Hills Bridge 500/230 kV Substation: Construction of a new substation in Clayton County to support both 500 kV and 230 kV transmission infrastructure.
Speedway 230 kV Substation: Construction of a new substation in Henry County that will serve this new data customer on the customer’s property.
O’Hara–Scherer 500 kV Transmission Line (Hills Bridge Loop): Approximately .25 mile of new 500 kV transmission line in Clayton County connecting the new substation to existing transmission facilities.
Hills Bridge–Speedway #1 230 kV Transmission Line: Approximately 1.5 miles of new 230 kV transmission line in Henry and Clayton counties.
Hills Bridge–Speedway #2 230 kV Transmission Line: Approximately 1.0 mile of new 230 kV transmission line connecting nearby substations and operating alongside other new facilities.

About the Project
What is this project and why is it happening?
The Hills Bridge–Speedway 500 kV Transmission Project includes construction of new transmission lines and substations in Henry and Clayton Counties to support the electrical needs of a large data center customer and strengthen the local transmission system. The project is necessary to provide reliable electric service in an area experiencing continued growth, while ensuring Georgia Power’s transmission network can safely and effectively serve current and future demand. The improvements also enhance overall grid reliability and support long‑term infrastructure needs for the region. Explore Data Center FAQs
How will this project benefit my community?
The Hills Bridge–Speedway 500 kV Transmission Project will strengthen the local electric grid by adding capacity and improving reliability in Henry and Clayton counties. The project supports the energy needs of a large data center that requires new transmission infrastructure, while also enhancing the system that serves homes, businesses, and critical facilities and increasing flexibility to support future growth and evolving energy needs across the region.
Is this transmission line being built to serve a specific customer or facility?
Yes, this project is being developed to serve the electric needs of a large‑load customer that requires new transmission infrastructure. The improvements also enhance the overall system, providing broader reliability benefits for the surrounding area.
General Transmission Questions
Why does Georgia Power need land for energy projects?
Energy infrastructure like transmission lines and substations helps ensure electricity remains reliable and affordable for the communities we serve. As Georgia continues to grow, we must responsibly expand and strengthen the grid to meet increasing demand. Learn more about the land acquisition process.
What are transmission lines?
Transmission lines transmit high-voltage electricity from the generation source or substation to another substation in the electric grid. Overhead transmission lines carry a three-phase current and can vary in voltage. Learn more.
What is a line route?
A line route refers to the path or corridor that a transmission line follows from its starting point to its endpoint. The route is selected based on various considerations, including safety, existing land uses in the area, existing transmission corridors, environmental conditions, engineering practices related to the construction and operation of the lines.
What is the Integrated Resource Plan?
The Integrated Resource Plan (IRP) guides investments in generation and transmission to meet forecasted demand, ensuring reliable service for all customers. More about the IRP and our long-term energy planning process managed by the Georgia PSC
What is an easement?
An easement is a legal right to use another person's land for a specific purpose, where a payment is paid to the owner of the property in return for the right of easement. This right allows the easement holder to enter and use the land for activities such as utility installation, access, or maintenance. The original owner retains legal title to the land, but the easement holder has the right to use it as specified in the easement agreement.
Are there health risks or safety concerns from living near substations or power lines?
Decades of research show no link between EMF exposure from power lines and disease. EMFs are common in everyday electrical devices, and power lines meet national safety standards.
We are committed to keeping residents, business owners, and all community members informed throughout every stage of the project. Please submit any questions you have here.
