Lexington County, South Carolina, weighs data center regulations amid growing AI demand

• Lexington County, South Carolina, is considering data center regulations.
• A large data center facility may consume about 5 million gallons of water each day.
• Data centers could account for as much as 12% of total U.S. electricity use by 2028.

For infrastructure planners, the challenge lies in optimizing data center efficiency while mitigating environmental impact. Strategies like renewable energy integration, water recycling, and smart grid technologies could alleviate pressures. However, without clear regulations, the county risks facing unmanaged growth similar to other regions grappling with AI's resource demands.

The upcoming October 31, 2026, moratorium deadline in Lexington County will be a critical checkpoint for how local governments adapt to AI's infrastructure needs.

Regional Regulatory Divergence

This divergence reflects broader tensions between economic development and resource management as AI infrastructure expands across South Carolina's rural counties.

Newberry County's moratorium, approved in July 2026, provides time to assess environmental impacts and establish guidelines for future projects ◉ thecooldown.com · 1. Edgefield County's proposed limits target specific concerns: noise from cooling systems, water usage equivalent to 5 million gallons daily for large facilities, and electricity demands exceeding 400 megawatts—similar to Google's Berkeley County campus ◉ thecooldown.com · 1◉ yahoo.com · 2. These measures signal growing scrutiny of data centers' ecological footprints amid projections that they could consume 12% of U.S. electricity by 2028 ◉ thecooldown.com · 1.

Lexington County's approach remains intermediate, avoiding outright bans while exploring zoning adjustments and utility planning. The October 31, 2026, moratorium deadline will determine whether it adopts stricter controls or maintains its current framework, balancing potential economic gains against resource sustainability challenges ◉ thecooldown.com · 1.
