- Is there a map of Wisconsin 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 Wisconsin?
- Port Washington Generating Station, at 1 GW. The table is sorted largest first, so the rest follow it.
- Is there a natural gas power plant near me in Wisconsin?
- 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 Wisconsin's natural gas power plants?
- Most of them sit inside MISO, according to the balancing-authority code EIA files against each plant. Live conditions for that market are on this site.
- 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.
