Georgia Just Released Eye-Popping New Energy Demand Estimates

We’ll give you one guess as to what’s behind the huge spike.

Georgia is going to need a lot more electricity than it once thought. Again.

In a filing last week with the state’s utility regulator, Georgia Power disclosed that its projected load growth for the next decade from “economic development projects” has gone up by over 12,000 megawatts, to 36,500 megawatts. Just for 2028 to 2029, the pipeline has more than tripled, from 6,000 megawatts to 19,990 megawatts, destined for so-called “large load” projects like new data centers and factories.

To give you an idea of just how much power Georgia businesses will demand over the next decade, the two new recently booted up nuclear reactors at Vogtle each have a capacity of around 1,000 megawatts. Of the listed projects that may come online, five will require 1,000 megawatts or more.

The culprit is largely data centers. About 3,330 megawatts’ worth of data centers have broken ground in Georgia, and just over 4,100 megawatts are pending construction, vastly outstripping commitments made by industrial customers.

“New load growth, led predominately by data centers, could triple [Georgia Power’s] size, in ten years. This is the second industrial revolution, led by artificial intelligence,” Simon Mahan, the executive director of the Southern Renewable Energy Association, wrote on X.

Georgia Power is used to upgrading load forecasts. The company had to update its three-year planning process (known as an integrated resource plan, or IRP) in October of 2023, just a year after releasing its previous three-year plan, as its five-year load growth projections had grown from 400 megawatts to 6,660 megawatts, a 17-fold increase. Regulators approved the new plan in April of this year, which included adding turbines to an existing gas-fired plant, pushing out the retirement of a coal-fired plant, and more battery storage.

The latest update, Georgia Power said in the filing, “should provide further certainty that Georgia Power’s load forecast is materializing and that the constructive outcome of the 2023 IRP Update is supportive of economic growth in Georgia.”

The Country’s Largest Power Markets Are Getting More Gas

Three companies are joining forces to add at least a gigawatt of new generation by 2029. The question is whether they can actually do it.

Two of the biggest electricity markets in the country — the 13-state PJM Interconnection, which spans the Mid-Atlantic and the Midwest, and ERCOT, which covers nearly all of Texas — want more natural gas. Both are projecting immense increases in electricity demand thanks to data centers and electrification. And both have had bouts of market weirdness and dysfunction, with ERCOT experiencing spiky prices and even blackouts during extreme weather and PJM making enormous payouts largely to gas and coal operators to lock in their “capacity,” i.e. their ability to provide power when most needed.

Now a trio of companies, including the independent power producer NRG, the turbine manufacturer GE Vernova, and a subsidiary of the construction firm Kiewit Corporation, are teaming up with a plan to bring gas-powered plants to PJM and ERCOT, the companies announced today.

The three companies said that the new joint venture “will work to advance four projects totaling over 5 gigawatts” of natural gas combined cycle plants to the two power markets, with over a gigawatt coming by 2029. The companies said that they could eventually build 10 to 15 gigawatts “and expand to other areas across the U.S.”

So far, PJM and Texas’ call for new gas has been more widely heard than answered. The power producer Calpine said last year that it would look into developing more gas in PJM, but actual investment announcements have been scarce, although at least one gas plant scheduled to close has said it would stay open.

So far, across the country, planned new additions to the grid are still overwhelmingly solar and battery storage, according to the Energy Information Administration, whose data shows some 63 gigawatts of planned capacity scheduled to be added this year, with more than half being solar and over 80% being storage.
