Generating units
| Unit | Technology | Nameplate | Summer | Online | Status |
|---|---|---|---|---|---|
| 2 | Petroleum Liquids | 1.1 MW | 1.1 MW | 1968 | Operating |
| 4 | Petroleum Liquids | 1.1 MW | 1.0 MW | 1964 | Operating |
| 1 | Petroleum Liquids | 0.6 MW | 0.6 MW | 1956 | Operating |
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 2.8 MW solar plant and a 2.8 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 Iowa power plants · What Iowa actually generates
