Generating units
| Unit | Technology | Nameplate | Summer | Online | Status |
|---|---|---|---|---|---|
| GEN1 | Municipal Solid Waste | 64 MW | 58 MW | 1989 | Operating |
| GEN2 | Municipal Solid Waste | 34 MW | 28 MW | 2013 | Operating |
| PV1 | Solar Photovoltaic | 2.9 MW | 2.7 MW | 2020 | 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 100 MW solar plant and a 100 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
