How many solar farms are in Idaho?

14, with 827 MW of nameplate capacity between them, spread over 5 counties. That is the EIA-860M operating count for 2026-07.

Is there a map of Idaho solar farms?

Yes — the map above. Each dot is one solar farm, sized by nameplate capacity and placed at the coordinates EIA files for it.

Which is the largest solar farm in Idaho?

Matrix Pleasant Valley, at 200 MW. The table is sorted largest first, so the rest follow it.

Is there a solar farm near me in Idaho?

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 Idaho's solar farms?

No single ISO or RTO covers most of them. EIA files each plant against its own balancing authority, which in Idaho 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. Solar photovoltaic and solar thermal, with and without storage. Utility-scale only: EIA-860M starts at 1 MW, so rooftop solar is not here. 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.
