This is a source-attributed discovery row. It can help you find a place and its citations; it is not a DataCenterData finding that the facility is distinct or currently operating.

Provider notes
Energy. At full buildout the campus could require up to 1,400 MW: roughly 1,000 MW from a co-located natural-gas turbine plant on site, plus up to 400 MW imported from the grid at peak. The generation plant is tracked separately as alterra-marshall-technology-energy-center-gas-mi.
Water. Developer describes a closed-loop liquid cooling system intended to minimize water use; the Marshall mayor put daily use at about 2,000 gallons a day.
Community. City of Marshall reworking noise ordinances ahead of the project; public concern over noise, emissions, and impact on Stuart Lake and an adjacent city-owned nature preserve.
What the source record says
Proposed data center (Marshall Technology & Energy Center, MTEC) plus a co-located natural-gas electric generation facility within Brooks Industrial Park, Marshall. WWMT (2026-04) resolves the load split that earlier reporting left open: up to 1,400 MW required at full buildout, around 1,000 MW of that from on-site gas turbines and up to 400 MW imported from the grid at peak — so capacityMw.planned is the campus power requirement and the 1 GW plant is carried both in energy.onSiteGenerationMw and as its own power_generation record. ~270 acres (112 buildable), roughly half wetlands. Alterra (Toronto-based) estimates 300-500 direct high-skill jobs. Mayor Wolfersberger (2026-01) called it "just a concept" with "no site plans or utility agreements yet"; due diligence runs into Q3 2026, then construction is "probably 18 months to two years away" if approved. Land is already zoned heavy industrial, so no public referendum is required (unlike Augusta Township). Planned closed-loop liquid cooling. Coordinates are an approximate Marshall-area estimate, not parcel-geocoded; the LDFA purchase price ($1.12M) is for land only, not a project investment figure. capacityMw and jobs deliberately left unfilled rather than normalized: the source gives a ceiling ('up to 1,400 megawatts') and a range ('300 to 500 skilled jobs') that does not distinguish construction from permanent. The $1.12M is the land purchase price, not project investment. Figures recorded here for a maintainer to promote if the hedged forms are acceptable.
Any MW value is reproduced as source-reported context. Its measurement boundary is not established consistently enough for comparison. Unknown is not zero.

Compute Atlas 1.34.1 with retained prior rows and publication holds. This is a DataCenterData composite, not an unmodified publisher edition. This row uses the captured source from 1.34.1, source as of 2026-10-14T20:40:52.293Z.
That does not mean the row is wrong, and it does not mean no reviewed record exists for the same place. A link is added only when an identifier or source establishes the match.
