Generating units
| Unit | Technology | Nameplate | Summer | Online | Status |
|---|---|---|---|---|---|
| 1 | Conventional Hydroelectric | 31 MW | 20 MW | 1978 | Standby/Backup: available for service but not normally used |
| 2 | Conventional Hydroelectric | 31 MW | 33 MW | 1978 | Out of service but expected to return to service in next calendar year |
| 3 | Conventional Hydroelectric | 31 MW | 34 MW | 1978 | 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 92 MW solar plant and a 92 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 Idaho power plants · What Idaho actually generates
