How the units landed on your bill
Georgia Power recovers the cost of a power plant through base rates, the part of your bill that pays for the company's plants, poles, and wires rather than the fuel it burns. When the Georgia Public Service Commission, the five elected commissioners who set those rates, approves a plant as used and useful, the construction bill shifts from the company's books onto the customer's monthly statement. Vogtle 3 and 4 made that shift in two steps, one as each unit reached commercial operation.
The station sits on the Savannah River near Waynesboro, and Georgia Power owns a bit under half of it. The rest belongs to Oglethorpe Power, MEAG Power, and Dalton Utilities, which means many co-op members and municipal customers across the state help pay for the same two reactors, through their own providers rather than through Georgia Power.
The honest math on the monthly figure
Figure it this way: the commission has described the Vogtle piece as adding roughly 5 percent to a typical residential bill once both units were running, which lands on the order of nine dollars a month for an average home, at last public report. Your own figure depends on how much power you use; a larger all-electric house in August, when Georgia's air conditioning runs hard, carries more of it than a small apartment in April.
That nine-dollar figure is not the only thing that moved. Fuel costs, storm recovery, and other riders rose or fell on their own schedules over the same period, so the number on your statement reflects several decisions stacked together, not Vogtle alone.
The prudence fight that came first
Before customers picked up the construction cost, there was a prudence review, the regulators' check on whether the money was spent wisely enough to charge ratepayers for all of it. Vogtle ran years late and ended up costing well over thirty billion dollars across all its owners, against an original estimate back in the mid-teens of billions, so the question of who absorbs the overrun was real money.
In 2023, Georgia Power and the commission's staff reached a settlement that split the difference: the company agreed to eat a share of the overrun, and customers covered the rest. The deal avoided a drawn-out hearing, and reasonable people still disagree about whether it landed in the right place.
What 2,200 megawatts actually buys
For the money, the grid gets two Westinghouse AP1000 reactors of roughly 1,100 megawatts each, about 2,200 megawatts together, enough to power something like a million homes. They run as baseload, meaning around the clock rather than only at peak, and they produce no carbon dioxide while operating, which matters as Georgia Power retires coal units.
Nuclear licenses run for decades, so the plan is for these units to generate long after the construction debt is paid down. Whether they prove a bargain depends on how natural gas and solar prices move over the next forty years or so, and that is genuinely unknown.
Worth watching this month
1. Watch the Georgia Public Service Commission docket site for Georgia Power's next base rate review, the routine proceeding where any further Vogtle true-up would surface.
2. The commission posts Vogtle construction and cost monitoring reports, and the final reconciliation filings are the ones worth reading closely.
3. Nuclear Regulatory Commission inspection reports for Units 3 and 4 are public and show how the new reactors are actually running, mostly routine but occasionally not.
4. The EIA's Georgia electricity profile updates through the year and will show nuclear's rising share of the state's power mix.
5. Any new fuel cost rider filing can move your bill independently of Vogtle, so it is worth separating from the construction line when you compare statements.
