Drying Grid: How Expanding U.S. Drought Threatens Energy Supply — and Data Centers

Drought is no longer a regional anomaly — it is a structural risk to the U.S. energy system and the digital economy it powers.
The U.S. Drought Monitor shows significant portions of the country under moderate to severe drought. While agriculture often dominates the headlines, the implications for power generation — and high-density data infrastructure — are just as material.
Water is embedded across the energy value chain:
• Hydropower: Reduced snowpack and declining reservoir levels limit output in Western power markets.
• Thermal generation: Natural gas, coal, and nuclear plants depend on water for cooling. Low river levels and elevated intake temperatures can force derates or temporary shutdowns.
• Fuel transport: Shallow waterways can disrupt barge traffic, tightening fuel supply chains.
• Wildfire exposure: Drought-stressed vegetation increases fire risk near transmission corridors, threatening grid stability.
The ripple effects extend directly to data centers.
Large-scale facilities require substantial, reliable electricity — and many rely on water-intensive cooling systems. During drought, utilities may impose water-use restrictions, increasing operating costs or forcing a shift to less efficient cooling methods. At the same time, extreme heat tied to drought drives electricity demand higher, tightening regional capacity margins.
Data centers also face physical risks. Wildfire threats can endanger transmission lines serving hyperscale campuses, while smoke and particulate matter raise filtration and air-handling challenges. In water-stressed basins, permitting for new facilities may face increased scrutiny, affecting site selection and expansion timelines.
According to NOAA, drought forms when prolonged precipitation deficits combine with elevated temperatures and evaporation. Climate variability is intensifying these conditions, increasing the frequency of compound risks: heat, dry soils, wildfire, and peak power demand.
The National Drought Information System emphasizes integrated monitoring and early warning. For grid operators and data center developers, that means incorporating hydrological modeling, AI-driven load forecasting, wildfire risk analytics, and water-availability stress testing into planning frameworks.
As AI workloads expand and hyperscale campuses multiply, drought risk becomes a critical infrastructure variable. Energy security, water security, and digital resilience are now tightly linked.
Drought is no longer just a climate story — it is a power and data story.
