How many natural gas power plants are in Oregon?

12, with 4 GW of nameplate capacity between them, spread over 6 counties. That is the EIA-860M operating count for 2026-07.

Is there a map of Oregon natural gas power plants?

Yes — the map above. Each dot is one natural gas power plant, sized by nameplate capacity and placed at the coordinates EIA files for it.

Which is the largest natural gas power plant in Oregon?

Hermiston Power Partnership, at 689 MW. The table is sorted largest first, so the rest follow it.

Is there a natural gas power plant near me in Oregon?

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 Oregon's natural gas power plants?

No single ISO or RTO covers most of them. EIA files each plant against its own balancing authority, which in Oregon 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. Combined cycle, combustion turbine, steam turbine, internal combustion and other gas-fired 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.
