Data Center Site Selection in Georgia: The Southern Company Power Playbook

Georgia Power operates under a regulated, integrated resource planning model managed by the Georgia Public Service Commission. Unlike ERCOT or PJM, there is no open interconnection queue for load customers to enter directly. Timelines depend on substation capacity, the IRP cycle, and PSC-approved generation buildout. The December 2025 approval of 9,885 MW of new generation will take 3-5 years to construct and deliver, meaning near-term capacity is constrained to existing substation headroom.

Georgia offers a sales and use tax exemption for data centers investing $100M+ (threshold scales by county population). The exemption covers computer equipment, emergency generators, cooling towers, air handling units, and energy storage systems. Co-located facilities investing $100M-$250M qualify for full exemption. However, SB 408 and SB 410 filed in January 2026 seek to repeal this exemption starting January 2027. The 2026 session adjourned without action, but the legislative threat continues.

Atlanta rose from #6 to #2 nationally by net absorption, surpassing Northern Virginia in 2024 with 705.8 MW absorbed vs. NoVA's 451.7 MW. Key drivers: robust fiber infrastructure (Tier 1 peering hub), Southeast regional demand, favorable land availability outside metro core, competitive power rates (~9.94 cents/kWh), and strong state economic development support. The market currently supports 0.88 GW installed and is projected to reach 2.99 GW by 2030 at a 27.71% CAGR.

The CIR program, approved by the Georgia PSC, allows hyperscale and large commercial customers to identify and pay for their own clean energy projects (solar, battery, renewables) to be built and connected to Georgia Power's grid. If the procured power is cheaper than utility-generated equivalents, 75% of savings flow to the participating customer and 25% are shared with other ratepayers. This gives data center operators a path to secure renewable energy within a regulated utility framework.

Water consumption varies dramatically by cooling technology. Evaporative systems can use up to 9 million gallons per day during peak summer. Closed-loop systems reduce this to under 100,000 gallons/day. Meta's Newton County facility uses approximately 500,000 gallons daily — roughly 10% of the entire county's water supply. Metro Atlanta's position at the headwaters of six small river systems makes water a critical constraint. Counties are beginning to require water impact assessments as a permitting condition.

Community opposition is a material risk in Georgia. Citizens for Rural Coweta collected 8,000+ signatures opposing the $17B Project Sail. Columbia County faced pushback on three separate proposals. Newton County residents reported wells running dry after Meta's facility opened. The political backlash contributed to Democrats winning upset victories on the Georgia PSC in recent elections. However, Douglas County and some rural communities (Early County, Dalton) have been more receptive, especially where data centers replace closed industrial facilities.

The Georgia market is dominated by hyperscalers and major operators: Google ($8B Project Pegasus in LaGrange, plus existing facilities), Microsoft ($1.8B across 3 facilities in Douglas County, 324 MW), Prologis ($17B Project Sail in Coweta County, 900 MW), QTS (Excalibur campus in Fayetteville, $1B+, plus Suwanee and Early County), Switch ($772M Bartow County campus), Core Scientific (Dalton, opening July 2026), T5 Data Centers (Atlanta IV), Flexential (5 Atlanta-area facilities, 73 MW), and DC BLOX (Douglas County hyperscale campus).
