Generating units
| Unit | Technology | Nameplate | Summer | Online | Status |
|---|---|---|---|---|---|
| MAIN3 | Solar Photovoltaic | 4.1 MW | 4.1 MW | 2020 | Operating |
| MAIN2 | Solar Photovoltaic | 3.9 MW | 3.9 MW | 2020 | Operating |
| MAIN1 | Solar Photovoltaic | 2.6 MW | 2.6 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 11 MW solar plant and a 11 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
