Grand Tower Energy Center: 347 MW of Grid Headroom + Up to 640 MW of Gas Generation Potential

347 MW of grid headroom at the existing Ameren 138 kV bus, plus up to 640 MW of on-site gas generation potential. Air permitting is required for new generation, and the seller will support the process. Acreage and power figures are per the seller's offering memorandum; buyer to verify.

46 acres are conveyed for two brand-new utility substations (345 / 138 / 69 kV). Ameren: under construction, targeting 2027/28 in-service.

±305 contiguous acres for the core site, plus 160 additional acres available for expansion, on the Mississippi River in Grand Tower, Jackson County, Illinois.

Yes. Gas at the fence: NGPL Gulf Coast transmission (16″–30″) serves the site.

Mississippi River frontage with existing intake infrastructure and barge access. Clearwave fiber backbone at the site perimeter. Jackson County is in NAAQS attainment and has no data center moratorium.

Price on request; offers by LOI. All offers are subject to ownership approval.

The full data room (title, ALTA survey, flood, air, environmental, easements, PVcase study) is available under NDA. Contact Carson Jones at eXp Commercial for details.

Texas still leads on data center count and incentives, but the path to power has slowed. On August 3, 2026, Gov. Greg Abbott directed the Public Utility Commission of Texas and ERCOT to audit data centers seeking to connect to the ERCOT grid, and projects that fail the audit are to be denied a connection. No deadline was set, and lawmakers are also questioning the state's data center sales tax exemption, which now costs more than $1 billion a year. For a user that needs certainty on power, a site with grid headroom already identified outside ERCOT is worth a look: Grand Tower Energy Center has 347 MW of grid headroom at Ameren's existing 138 kV bus in MISO.

Power availability is still the deciding factor, so the best alternatives are places that can deliver megawatts on a known timeline. Markets drawing attention include Pennsylvania, the Carolinas, Central Washington, Louisiana, Mississippi, Oklahoma and the TVA region. Southern Illinois belongs on that list: Grand Tower Energy Center pairs 347 MW of grid headroom with up to 640 MW of on-site gas generation potential (air permits required), NGPL gas at the fence, Mississippi River water and ±305 contiguous acres.

Moratoriums and local limits on data centers spread through 2026, so the community and county matter as much as the state. Jackson County, Illinois, home of Grand Tower Energy Center, has no data center moratorium and is in NAAQS attainment for air quality, which matters when permitting new gas generation. Buyers should confirm local requirements in diligence.

Ask the utility three things: how much offtake capacity is available at the nearest substation, how much of it is already claimed by projects ahead of you in the queue, and which rate class or large-load tariff will apply. At least three dozen states have adopted or proposed large-load tariffs, so the answer affects cost as well as timing. At Grand Tower, the seller's offering memorandum shows 347 MW of grid headroom at the existing Ameren 138 kV bus, and Ameren is building two new 345 / 138 / 69 kV substations on 46 conveyed acres, targeting 2027/28 in-service. Buyer to verify with the utility.
