Georgia has approved one of the largest single utility build-outs tied to data centers in the country, with a condition aimed squarely at the fear that the data centers might not show up. On December 19 the Georgia Public Service Commission voted 5-0 to approve a stipulated agreement allowing Georgia Power to add 9,885 MW of new resources. The commission said most of the new energy will serve large new customers such as data centers. Under the agreement, Georgia Power will financially backstop the new projects in 2029, 2030 and 2031, so that existing customers do not pay if the expected load fails to materialize.
What was approved
Georgia Power's July filing requested certification of more than 3,600 MW of new combined cycle gas generation, more than 3,000 MW of battery storage, 350 MW of batteries paired with solar, and more than 2,800 MW of power purchase agreements, according to the company. The Atlanta Journal-Constitution reported that the decision clears Georgia Power to invest at least $16 billion in new resources, including gas units with lives of at least 45 years. That figure excludes the cost of power bought from third-party plants. With those contracts and the grid connections new plants need, some groups estimate the total cost could reach $50 billion to $60 billion, the newspaper reported. It said roughly 60% of the new electricity will come from gas plants and the rest from batteries and some solar.
The backstop
The deal hinged on stranded-asset risk. The commission said its Public Interest Advocacy staff had raised concerns in testimony that Georgia Power and data centers had not signed contracts for all the load the 9,885 MW was meant to serve. If the demand did not appear, the new plants could become stranded assets paid for by existing customers.
The settlement answered that by approving all 9,885 MW while requiring Georgia Power to stand behind the new load. The backstop covers 2029 to 2031, beyond the existing base rate freeze that runs through the end of 2028. The commission said that if Georgia Power does not sign contracts with new data centers, regulators have ample time to alter or reverse the certification of the projects.
Georgia Power described the same commitment in financial terms. It said it will file its next base rate case in 2028 in a way that ensures incremental revenue from large-load customers delivers benefits of at least $556 million a year, equivalent to $8.50 a month, or about $102 a year, for a typical residential customer using 1,000 kWh a month. The commission described this as $8.50 a month of downward pressure on the average household bill.
The commission also stressed the limits of its role. It does not approve data center construction, location or operation; its jurisdiction covers how Georgia Power supplies energy to new and existing customers. Georgia Power serves 2.8 million customers in all but four of the state's 159 counties, so the cost allocation decided here reaches a large share of the state's households.
Commission Chairman Jason Shaw said the agreement ensures that data centers, or if necessary Georgia Power itself, will pay for the new infrastructure, and that existing customers will not.
How much load is signed
The size of the signed pipeline was a central question. The AJC reported that Georgia Power's director of resource planning, Jeffrey Grubb, testified that the utility had signed contracts with data centers representing 7,900 MW of demand. Georgia Power said it has filed more than 3 GW of new customer contracts with the commission this year under rules adopted in January, which require large-load customers to make larger financial commitments and demonstrate infrastructure readiness to stay in the utility's long-term pipeline. Its November large-load report showed construction underway or pending for nearly 30 large-load projects across the state.
The company argues that growth in large loads helps spread fixed costs and has made its current three-year base rate freeze possible. Critics are less sure. The Southern Environmental Law Center, representing several groups, petitioned for more information and said after meeting with the utility that it had serious concerns about the strength and scope of its financial promises, the AJC reported.
The political backdrop
The vote came weeks after Georgia voters ousted two Republican commissioners, Fitz Johnson and Tim Echols, in favor of Democrats Alicia Johnson and Peter Hubbard, in races focused on frustration with rising power bills, according to the AJC. The new commissioners take their seats on January 1. Hubbard won an unusual one-year term and must run again in 2026, along with Commissioner Tricia Pridemore.
Echols, in one of his final votes, said the decision resolved Georgia's power needs until 2031. After that, he said, data centers may need to take the financial risk for building out the nation's nuclear future, paying the learning curve so that states can later build small modular reactors more cheaply.
What the Georgia model shows
The structure answers a question that regulators across the country are asking: who pays if data center demand falls short? In PJM, the answer has mostly been the capacity market, where higher prices spread costs across all customers. Georgia, a vertically integrated state, has put the risk on the utility's shareholders for a defined period, while letting the utility build ahead of signed demand.
That is a meaningful protection, but a limited one. The backstop covers three years. The gas units approved will run for decades. If data center demand holds, the plants will be paid for by the customers they were built to serve. If it fades after 2031, the question of who pays for the remaining life of the plants returns, before a commission whose membership and politics are already changing.
The scale also matters for the region. Nearly 10 GW of new resources for one utility is comparable to adding several large power stations in a single decision. Gas makes up the largest share, which ties Georgia's data center growth closely to pipeline capacity and gas prices. Batteries make up most of the rest, which reflects how quickly storage has become the default way to add capacity for peak hours.
