Princeton (IL): FAQ
- Where is Princeton (IL)?
- In Bureau County, Illinois (IL). The map on this page is placed at the coordinates EIA files for the plant, which locate the site rather than any individual unit.
- How big is Princeton (IL)?
- 38 MW of nameplate capacity across 8 units, as of the EIA-860M release for 2026-07.
- Who owns Princeton (IL)?
- EIA-860M names City of Princeton - (IL) as the reporting entity. That is the operator of record on the survey, which is not always the ultimate owner.
- Is this the same as Princeton (IL) LLC?
- Probably, but EIA-860M does not say. The survey records a plant name and a reporting entity — City of Princeton - (IL) here — not the project company that holds the asset. Project companies are commonly registered as an LLC carrying the plant's name, so a search for "Princeton (IL) LLC" usually means this site. This page shows only what EIA files, and does not assert a corporate structure it cannot see.
- Is Princeton (IL) still running?
