Opposition and litigation at this site

Yes. Amazon Project Rainier in New Carlisle, St. Joseph County, Indiana is contested. Hearings, public comment, petitions, or organized opposition are on record, and no lawsuit has been filed so far. IDEM cited Amazon and its contractor for unauthorized wetland impacts and halted work in affected areas pending Section 401 water-quality recertification; a April 2025 public hearing drew 100+ residents opposing a pending wetland-fill permit near Bendix Woods County Park, with concerns over aquifer depletion and utility rates.

How the community has taken it

Reception is a sourced signal, not an editorial judgment: contested means active public debate is on record, with hearings, petitions, or organized opposition, without litigation.

Power and water

Served by Indiana Michigan Power, an AEP subsidiary. Amazon states it matches consumption with 100% renewable energy; local grid mix is largely nuclear and coal. AEP is acquiring a natural gas plant in Ohio to help serve the load via the grid.

Outside-air (free) cooling for roughly 98% of operating hours, running essentially chiller-free. 1.58 MGD is the Phase 1 permitted cooling-water discharge cap (average discharge ~0.8 MGD). As of July 2026, full-campus water use was not publicly disclosed by AWS; residents have raised aquifer-withdrawal concerns.

Notes on the record

No operational capacity is recorded because neither Amazon nor the utility has stated one. Measured AI estimated the first nine buildings at "an estimated 590 MW of IT capacity" (June 2026), and Epoch AI estimates 910 MW of IT power from satellite imagery (updated July 2026); both are outside estimates. No planned capacity is recorded either: the 2,200 MW is the full-site electricity draw reported at the October 2025 opening ("30 buildings drawing up to 2.2 gigawatts (GW) of electricity", Converge Digest), an upper limit on grid draw, not IT load; Measured AI later gives 32 buildings and 2.25 GW of grid draw at full build-out.

What the record does not establish, and the document that would

In every fight on our tracker the decisive fact came out of a public records request. These are the requests for this site.

Power capacity in megawatts

Which document closes each gap

Power capacity in megawatts: The utility's large load service agreement, the interconnection request in the grid operator's queue, or the electrical site plan in the permit file.

Distances are between recorded coordinates, many of which are a city or county centroid, so treat them as approximate. Cumulative load on one utility and one aquifer is the question a planning commission rarely asks.
