Frozen locally, and shrinking: Marshall has a moratorium that blocks approval of any data center until at least August 2027. The developer has since dropped the on-site gas plant that would have carried a gigawatt, cutting the projected power demand by about 60 percent.
Water
Closed-loop liquid cooling proposed to minimize water use; developer said it would not draw from Stuart Lake (reported, Dec 2025). No gpd figure sourced.

Grid import (peak), 0.40 GW grid interconnect, Announced. Up to ~400 MW grid import at peak; MISO region, supplying utility unconfirmed.

On-site natural gas turbine plant, 1 GW gas, Announced. ~1,000 MW behind-the-meter gas; air permit not yet filed.

Marshall Technology & Energy Center on-site gas plant, 1 GW gas, Cancelled. ~1,000 MW on-site natural-gas turbines originally proposed; Alterra later reportedly decided not to build the gas plant (mayor's statement, Aug 2026), cutting project energy use ~60%.

County water status: No drought in Calhoun County, week of 2026-09-22 (US Drought Monitor). Data centers are large water users for cooling; this is the neutral local water picture.
