Oil-Fired Power Plants in Wyoming: FAQ

How many oil-fired power plants are in Wyoming?
2, with 5 MW of nameplate capacity between them, spread over 1 county. That is the EIA-860M operating count for 2026-07.
Is there a map of Wyoming oil-fired power plants?
Yes — the map above. Each dot is one oil-fired power plant, sized by nameplate capacity and placed at the coordinates EIA files for it.
Which is the largest oil-fired power plant in Wyoming?
Lake (WY), at 3 MW. The table is sorted largest first, so the rest follow it.
Is there a oil-fired power plant near me in Wyoming?
The county roll-up below groups every plant by county, which is the quickest way to find the one closest to a given town.
Which grid operator runs Wyoming's oil-fired power plants?
No single ISO or RTO covers most of them. EIA files each plant against its own balancing authority, which in Wyoming is largely a vertically integrated utility rather than an organised market.
How current is this, and what is left out?
EIA-860M for 2026-07. Petroleum liquids and petroleum coke. Many are peakers or standby units. Plants below 1 MW are not surveyed by EIA and so are absent; retirements and additions after 2026-07 arrive with the next monthly release.
