Georgia Power is continuing its modernization efforts for its hydroelectric fleet, aiming to support the state’s growing energy needs and maintain compliance with federal regulations. The company owns and operates 15 hydro generation facilities in Georgia, with an ownership interest in a 16th facility. Together, these sites include 66 hydroelectric generating units that provide more than 1,100 megawatts of capacity.
Many of Georgia Power’s hydro plants have been operational for over a century and are licensed by the Federal Energy Regulatory Commission under the Federal Power Act. These facilities not only generate emission-free electricity but also offer recreational opportunities to millions of residents through public access to lakes such as Oconee, Burton, and Tugalo.
Recent investments in the hydro fleet were reviewed and approved by the Georgia Public Service Commission as part of the company’s 2025 Integrated Resource Plan. Upgrades are planned at several sites including Tallulah, Yonah, Bartlett’s Ferry, and North Highlands. These projects focus on replacing or refurbishing essential equipment like turbines and generators that have reached or are nearing the end of their useful life.
The company reports that these modernization projects are intended to extend the operational lifespan of its hydro resources by at least another 40 years while improving efficiency and reliability for customers.
“For more than a century, Georgians have enjoyed reliable electricity from our hydro plants located on lakes and rivers across the state,” said Rick Anderson, Georgia Power senior vice president and senior production officer for Georgia Power. “As we continue to work with the Georgia PSC to invest in our generation fleet to meet the needs of a growing Georgia, modernizing our hydro facilities helps to ensure continued compliance with federal regulations and our licenses, as well as providing additional longevity for the units and overall value for customers.”
A recent filing with the Public Service Commission detailed completed upgrades at Plant Tugalo near Turnerville. Work there included generator replacements, turbine replacements, and updates to balance-of-plant systems such as lubricating oil systems and plant controls. Similar upgrades were previously finished at Plant Terrora.
Progress was also reported at Plants Bartlett’s Ferry (where Unit 1 returned to service in July), Nacoochee, Oliver, Burton, and Sinclair. The scope of work at Bartlett’s Ferry includes generator rewinds, turbine replacements, and system upgrades similar to those completed elsewhere in the fleet.
