Generating units
| Unit | Technology | Nameplate | Summer | Online | Status |
|---|---|---|---|---|---|
| GEN3 | Natural Gas Fired Combined Cycle | 112 MW | 112 MW | 1991 | Operating |
| GEN1 | Natural Gas Fired Combined Cycle | 97 MW | 78 MW | 1991 | Operating |
| GEN2 | Natural Gas Fired Combined Cycle | 97 MW | 78 MW | 1991 | 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 307 MW solar plant and a 307 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 Rhode Island power plants · What Rhode Island actually generates
