Wind Farms in Montana: FAQ
- How many wind farms are in Montana?
- 23, with 2 GW of nameplate capacity between them, spread over 13 counties. That is the EIA-860M operating count for 2026-07.
- Is there a map of Montana wind farms?
- Yes — the map above. Each dot is one wind farm, sized by nameplate capacity and placed at the coordinates EIA files for it.
- Which is the largest wind farm in Montana?
- Clearwater Wind I, at 366 MW. The table is sorted largest first, so the rest follow it.
- Is there a wind farm near me in Montana?
- 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 Montana's wind farms?
- No single ISO or RTO covers most of them. EIA files each plant against its own balancing authority, which in Montana 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. Onshore and offshore wind turbines. 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.
