Which grid operator runs Wyoming's coal 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. Conventional steam coal and integrated gasification combined cycle. 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.
