Generating units
| Unit | Technology | Nameplate | Summer | Online | Status |
|---|---|---|---|---|---|
| 1 | Petroleum Liquids | 1.5 MW | 0.5 MW | 2002 | Standby/Backup: available for service but not normally used |
| 2 | Petroleum Liquids | 1.5 MW | 0.5 MW | 2002 | Standby/Backup: available for service but not normally used |
| 3 | Petroleum Liquids | 1.5 MW | 0.5 MW | 2004 | Standby/Backup: available for service but not normally used |
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 South Dakota power plants · What South Dakota actually generates
