Generating units
| Unit | Technology | Nameplate | Summer | Online | Status |
|---|---|---|---|---|---|
| 5 | Petroleum Liquids | 2.8 MW | 2.8 MW | 1975 | Standby/Backup: available for service but not normally used |
| 6 | Petroleum Liquids | 2.0 MW | 2.0 MW | 2006 | Standby/Backup: available for service but not normally used |
| 7 | Petroleum Liquids | 2.0 MW | 2.0 MW | 2006 | Standby/Backup: available for service but not normally used |
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 6.8 MW solar plant and a 6.8 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
