EPA rollback of carbon emission rules could keep Georgia coal plants running past 2030

Georgia's two largest coal plants, Plant Bowen and Plant Scherer, were scheduled to retire around 2030, but a new EPA rollback removes the carbon emission rules that would have forced cleaner generation by then. Georgia Power now plans to keep those plants online to serve data center demand, with coal providing about 70% of the projected shortfall. Last year the two plants produced roughly 22 million tons of carbon dioxide, close to half of the utility's fleet emissions. The EPA also says it expects coal use to increase tenfold and intends to repeal remaining carbon rules for new natural gas plants. That would affect projects like the proposed 1,500 MW NextEra plant in Mitchell County. Opponents point to mercury, heavy metals, and particulate pollution as local costs that outlast any federal policy. The rollback is expected to face court challenges.

The 2030 compliance date was already going to be tight. Scrapping it before the courts weigh in just hands Georgia Power cover to delay retirement decisions. What matters now is whether the PSC pushes back on the fuel mix in the next IRP.

The PSC has approved coal life extensions before. If data center demand is real, the cheaper path is still new gas plus storage. The IRP math only works if they ignore curtailment and transmission constraints.

The 70% coal dependency for data center load is the real number here. Bowen and Scherer are 40 to 50 years old. Even without carbon rules, maintenance and forced outages get worse. Someone needs to price in the reliability risk of leaning on those units for another decade.

Also worth remembering Bowen and Scherer emit more than CO2. The mercury and particulate load stays in the Altamaha watershed. That is a local cost that never shows up in the capacity factor.

The article notes the EPA expects coal use to increase tenfold. That seems optimistic in the other direction. Coal economics are still bad against gas and solar plus storage. The rule rollback changes the permit path, not the marginal cost of running old units.

Right. The data center load is real but so are interconnection queues. If Georgia Power is serious about 70% coal for that load, they need firm fuel supply contracts and transmission upgrades. Neither is quick or cheap.
