All Georgians’ lives and livelihoods are connected by a single grid of transmission power lines. Bracing the grid to handle the demand of one of the fastest-growing states means adding load-serving and bulk transmission lines. If lines weren’t built, affected regions of the state would see more frequent and longer outages. If neglected long enough, customers would face greater risks of brownouts and blackouts. We complete hundreds of construction projects, such as equipment upgrades, each year. At any given time, we usually have a dozen or more new power lines under construction.
Below is information on some of our largest projects. Please contact External Affairs at (770) 270-7050 for information on other projects.
Northeast grid upgrades
To keep electricity reliable in North Georgia, we have commenced work on a group of projects called the Northeast Grid Upgrades. They consist of a 500-kilovolt (kV) line from a substation a few miles east of Eatonton, running north to Walton County; four 230-kV lines; a 115-kV power line; three substations and one switching station.
Thomson-to-Warthen 500-kV line (New Delta Cat design)
We recently completed our first 500-kilovolt (kV) in 15 years. 500-kV lines are the largest type of power lines built in Georgia. With the 39-mile Thomson-to-Warthen line, Georgia Transmission introduced to the electric industry a new design for 500-kV lines, providing for a narrower footprint and improved access for maintenance.
