I'm not a Georgian, but I've done a lot of work in the state over the past 10 years. If you want the real story on the ground, I'd be happy to point folks to the locals grinding it out.

Kentucky regulators grant LG&E/KU permission to build power plants for future data centers State regulators are allowing Kentucky’s largest power companies to spend $3 billion on two new gas power plants, which LG&E/KU say are needed for future data centers.

Georgia Power says answer to state’s data center surge is more natural gas Georgia Power officials will make their case beginning Tuesday for gas-fired power plants and solar and battery storage to meet electricity demand driven by data centers.

“We’re starting to put more pressure on the gas system, and it’s not clear that the cumulative demand for gas is going to be sustainable or met in the next five years,” said Simon Mahan, executive director of the Southern Renewable Energy Association.
