 Planning & Constuction

In 1990, Georgia’s electrical system served about 6.5 million residents. Since then, the state has grown by more than 3 million people, and per-capita energy demand has grown at about twice the p​opulation rate. This growth has challenged the electric co-ops, Georgia’s fastest-growing electric utility group, to increase the capacity of transmission and distribution systems to keep outages and blackouts at bay. Since 2000, we’ve invested more than $1 billion in electric transmission on behalf of the state’s electric co-ops, adding almost 500 miles of new high-voltage lines and more than 150 substations. Our work has contributed significantly to millions of Georgians continuing to enjoy reliable electricity. 

 
Planning >>

We work with the state’s other major utilities to plan the statewide transmission system and ensure the grid can meet the challenges of changing requirements, such as shifts in population and the opening of new power plants. Meanwhile, area planners work with EMCs to study the performance of the local electric systems to meet their changing needs and keep service reliable.

Locating power lines >>

We strive to work with property owners and communities when locating new lines and substations. In fact, we developed one of the industry’s most sophisticated tools for objectively evaluating geographic conditions, a siting model that has been adopted by other electric utilities. Although most property owners would prefer not to accommodate new power lines, significant public controversy is rare. Building new facilities keeps Georgia’s electric service reliable. Our ability to build new lines and substations means that Georgia, unlike some other states, does not face severe electric transmission shortages, forced outages, emergency conservation during peak demand and political storms over solutions. Find out what opportunities we offer for community involvement.

Key issues >>

Building high-voltage power lines brings about not-in-my-backyard (NIMBY) complaints. To clear up misconceptions about transmission lines, such as underground construction and health effects from EMF, we offer our viewpoints in our key issues section.

GTC-EPRI siting model >>

Working with the Electric Power Research Institute, an independent electric industry research group in Palo Alto, Calif., we developed one of the most sophisticated tools available for analyzing potential transmission line sites. Developed with environmental groups, citizens groups and neighboring utilities, the model is the first to use a geographic information system developed by Photo Science, Lexington, Ky., that produces separate suitability maps for environmental, community and engineering perspectives. Find how this award-winning siting model helps us minimize effects on communities and the environment.

Easements and property rights >>

We work with hundreds of property owners each year to purchase the land or easements needed to build new power lines and substations. Learn the basics of easements and other issues involved with private land being used for a public purpose.

Projects >>

We currently build 25 to 100 miles of transmission lines and 5 to 15 substations each year. Along with more than 100 other system upgrades, our construction investments on behalf of the EMCs are more than $100 million per year. At any given time, the company is managing a dozen or more new power line projects. See maps and other details on some of our largest projects.​
