Georgia data centres and coal: the emissions math after rule

Georgia's largest utility faces a regulatory cliff. With the Trump administration's repeal of the greenhouse gas rule, the state's power generation emissions could double as utilities expand capacity to feed data centre demand.

The utility was already planning fossil fuel plant expansion. The rule repeal removes a federal brake on carbon-intensive generation. Data centre operators – predominantly tech giants – are bidding for power supplies across the Southeast, and Georgia's coal and gas infrastructure sits ready to meet that load.

This is not hypothetical. The calculation is specific: utilities locked into long-term data centre contracts will build generation assets that operate for 30+ years. Without the greenhouse gas rule, they have less pressure to mix in renewables or demand efficiency from tenants.

The outcome matters beyond Georgia. Data centres consume roughly 3–4% of US electricity today; projections suggest 5–6% within a decade. If that growth runs on unabated coal and gas – which is what Georgia's trajectory suggests – scope 1 and 2 emissions from the tech sector will surge, and scope 3 (customer emissions) will follow. Companies with net-zero commitments and science-based targets will face impossible arithmetic if their cloud providers are burning coal.

The policy risk here is real. Utilities are rational actors responding to regulation. Remove the rule, and investment flows to the cheapest generation, not the lowest-carbon. For procurement teams and sustainability leads at large organisations: your emissions contracts are now geographically and politically contingent in ways they weren't six months ago.

What happens when data centre electricity comes from a stranded asset?
