Georgia Power is continuing its efforts to modernize its hydroelectric fleet as part of a broader initiative to support Georgia’s growing energy needs. The company owns and operates 15 hydro generation facilities, with an ownership interest in a 16th, totaling 66 generating units and over 1,100 megawatts of capacity across the state. These facilities have provided emission-free electricity for more than a century and are licensed by the Federal Energy Regulatory Commission under the Federal Power Act.
The development of these hydroelectric plants has also contributed recreational opportunities for residents throughout Georgia. Lakes managed by Georgia Power, such as Oconee, Burton, and Tugalo, remain open to the public for camping and water sports.
Recent modernization plans were approved by the Georgia Public Service Commission (PSC) as part of the company’s 2025 Integrated Resource Plan. Upgrades will be made at several sites including Tallulah, Yonah, Bartlett’s Ferry, and North Highlands hydro facilities. These projects focus on replacing or refurbishing critical equipment like turbines and generators that are reaching or nearing the end of their useful life. The goal is to extend operational capabilities for at least another four decades while maintaining compliance with federal regulations.
“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 update filed with the PSC highlighted 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 control infrastructure. Similar upgrades had previously been finished at Plant Terrora.
Additional progress was reported at Plants Bartlett’s Ferry (north of Columbus), Nacoochee, Oliver, Burton, and Sinclair. Notably, Bartlett’s Ferry Unit 1 returned to service in July after completion of generator rewinds and other system replacements; Units 1-3 began operation in the 1920s while Unit 4 entered service in 1951.
