Generating units
| Unit | Technology | Nameplate | Summer | Online | Status |
|---|---|---|---|---|---|
| KAH1 | Conventional Hydroelectric | 1.5 MW | 1.5 MW | 2025 | Out of service and NOT expected to return to service in next calendar year |
| KAH2 | Conventional Hydroelectric | 1.5 MW | 1.5 MW | 2025 | Out of service and NOT expected to return to service in next calendar year |
| KAH3 | Conventional Hydroelectric | 1.5 MW | 1.5 MW | 2025 | 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 4.5 MW solar plant and a 4.5 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 Hawaii power plants · What Hawaii actually generates
