Solar Farms in Illinois: FAQ

How many solar farms are in Illinois?
450, with 5 GW of nameplate capacity between them, spread over 80 counties. That is the EIA-860M operating count for 2026-07.
Is there a map of Illinois 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 Illinois?
Double Back Diamond, at 593 MW. The table is sorted largest first, so the rest follow it.
Is there a solar farm near me in Illinois?
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 Illinois's solar farms?
Most of them sit inside PJM, 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. 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.
