Generating units
| Unit | Technology | Nameplate | Summer | Online | Status |
|---|---|---|---|---|---|
| 3 | Natural Gas Fired Combined Cycle | 111 MW | 101 MW | 2006 | Operating |
| 1 | Natural Gas Fired Combined Cycle | 95 MW | 84 MW | 2006 | Operating |
| 2 | Natural Gas Fired Combined Cycle | 95 MW | 84 MW | 2006 | 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 301 MW solar plant and a 301 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 California power plants · What California actually generates
