Data Center Moratoriums Reshape Local Siting
Coverage from Live 5 News, Post and Courier, and others
County governments across Georgia and South Carolina are using temporary moratoriums, zoning amendments, and impact studies to slow or condition data-center expansion.
Officials and residents repeatedly focus on electricity demand, grid and utility costs, potable water, cooling, noise, land conversion, and backup generation. Some jurisdictions are considering outright bans, while others are drafting industrial siting limits, buffers, performance standards, and cost-sharing rules. Large proposed campuses are driving the most contested decisions.
If you read one thing
It establishes the regional scale of South Carolina’s moratorium wave and explains how the statewide policy gap is producing divergent local rules.
Latest development
It captures the newest shift from a moratorium toward detailed, conditional zoning while covering infrastructure concerns and the broader local governance trend.
The counter-case
It presents the prohibition-or-extended-freeze position and links proposed restrictions to power, water, noise, and future development concerns.
The evidence
It supplies concrete evidence of how electricity, water allocation, reliability, and utility-cost pressures are shaping a local moratorium decision.
Moratoriums remain the main local response
Temporary bans, approval freezes, and study periods remain widespread across Georgia and South Carolina as counties assess impacts, consider permanent bans, or prepare replacement rules. The pattern is becoming mixed as some jurisdictions, including Colleton, convert pauses into conditional zoning frameworks while others continue extending or weighing moratoriums.
Local rules are becoming more prescriptive
Counties are moving beyond temporary pauses toward conditional approval systems that specify where and how data centers may operate. Current proposals and enacted rules include industrial or overlay districts, special permits, campus-size limits, residential buffers, noise caps, setbacks, and closed-loop or air-cooled systems.
Utility capacity is a binding approval constraint
Electricity demand, water availability, cooling, sewer capacity, reliability, and rate impacts continue to shape local decisions. Very large proposals—including a 1,000-megawatt project—are intensifying scrutiny of whether municipal utilities and surrounding infrastructure can absorb new demand without shifting costs or reducing reliability.
State policy gaps are producing fragmented local governance
With statewide South Carolina legislation stalled, counties and municipalities are independently deciding whether to pause, ban, or condition development. The resulting county-by-county responses vary in siting rules, utility obligations, operating standards, and permissible project scale.
120-day days
proposed moratorium duration on data center development
“The planning committee voted to advance a 120-day moratorium on data center development while potential environmental impacts are studied.”
15 counties
counties proposing or having passed temporary data center moratoriums
“At least 15 counties have proposed or passed temporary data center moratoriums, according to an analysis of media reports, council agendas and ordinances. That is an increase from earlier this summer, when The State reported that at least nine counties were considering a moratorium. Mount Pleasant, a municipality in Charleston County, has also begun considering a data center moratorium, making it one of the first towns in South Carolina to do so.”

12-month months
duration of Fairfield County's moratorium
“Fairfield County initially approved a 12-month moratorium in August. During the pause, county officials plan to research data centers through town halls, work sessions with experts and visits to existing facilities.”
2.4 billion gallons
Mount Pleasant Waterworks annual water allotment after reduction
“Nonetheless, after Google began tapping the aquifer, the town utility's annual water allotment was reduced in 2017 from 3.9 billion gallons to 2.4 billion gallons.”
Contested Issue
Should local governments prohibit or indefinitely pause data-center development, or allow it under strict zoning and operating conditions?
The corpus documents materially different local policy approaches. Some jurisdictions are considering bans or extended moratoriums because of anticipated effects on water, electricity, land use, and community infrastructure, while others are moving toward conditional approval frameworks that permit data centers in designated areas subject to enforceable siting, noise, cooling, setback, acreage, and water-use requirements.
Prohibition or extended freeze
Data centers should be banned or blocked through extended moratoriums until their potential effects on water, power, land use, and community infrastructure are resolved.
Conditional regulated approval
Data centers should remain permissible in designated areas if projects meet enforceable standards for noise, setbacks, cooling systems, water use, scale, and infrastructure impacts.
Colleton County replaces part of its moratorium with conditional data-center zoning
Colleton County has moved beyond a temporary pause in parts of its jurisdiction by approving an overlay district that permits data centers in designated areas under strict noise, setback, cooling, and acreage requirements.
Previously
Local governments are pausing or tightening data-center approvals, especially in Georgia and South Carolina, while officials develop zoning and infrastructure safeguards. Reviews repeatedly address electricity and water demand, utility costs, noise, emissions, land conversion, and public infrastructure, with large projects and organized opposition producing a fragmented local response.
The story now centers more sharply on large South Carolina hyperscale proposals, including one potentially expanding to 450 MW. New reporting also highlights the absence of statewide standards, leaving counties and newly involved state and regional agencies to manage impacts inconsistently.
The story now includes a concrete $1 billion Michigan hyperscale proposal facing a rezoning referendum and organized opposition, while Georgia counties are moving from temporary pauses toward decisions between regulated development and outright bans.
