Generating units
| Unit | Technology | Nameplate | Summer | Online | Status |
|---|---|---|---|---|---|
| AT1 | Natural Gas Fired Combined Cycle | 4.0 MW | 3.0 MW | 1985 | Operating |
| DPOX | Natural Gas Fired Combined Cycle | 0.7 MW | 0.7 MW | 1985 | Out of service and NOT expected to return to service in next calendar year |
Nameplate is the maximum rated output; summer capacity is what the unit can reliably deliver on a hot day, which is typically lower.

About this data
From EIA’s inventory of operable generators, May 2026 release. Capacity is nameplate — the maximum rated output of the equipment, not what the plant actually generates over a year, which depends on how often it runs. A 4.7 MW solar plant and a 4.7 MW nuclear plant have the same entry here and produce very different amounts of electricity.
“In service since” is the earliest in-service date among the units still listed, so a site rebuilt around newer equipment can read as younger than the site itself. All Illinois power plants · What Illinois actually generates
