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 Hawaii?

Kahe, at 610 MW. The table is sorted largest first, so the rest follow it.

Is there a oil-fired power plant near me in Hawaii?

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 Hawaii'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 Hawaii 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.
