What energy projects are proposed in Saline County?
The MISO interconnection queue lists 8 proposed projects in Saline County (6 solar, 2 solar plus storage), about 1,135 MW in all. 4 have a signed interconnection agreement.
What stands out in Saline County
By capacity, solar leads in Saline County with 810 MW across 6 projects, followed by solar paired with storage (2 projects, 325 MW). The largest is queue number J2793, a 250 MW solar request in the MISO queue, in study (Phase 2), filed Sep 2022, with a target in-service date of Jun 2026. Of the 8, 4 are still in study, 3 have a signed agreement and 1 is under construction. All of them are in the MISO queue, which covers the Ameren Illinois side of the state. The requests were filed between Mar 2018 and Oct 2024. Target in-service dates for those not yet under construction span Dec 2022 to Sep 2030; 5 of them have already passed, which means those schedules slipped.
A listing means a developer asked the grid operator to study connecting a project; many are never built, and the status column says where each one stands.
Reading the table: the queue number is the operator's ID for the request (MISO J-numbers, PJM AE/AF/AG-numbers); operators do not publish developer names in these files. Connection is the transmission owner and, where listed, the substation or line; "Other_" is the operator's own placeholder. In study (Phase 1/2) are MISO's definitive-planning study phases; "moved to TC1" means a PJM request was carried into Transition Cycle 1; "CIR Increase" is a request to add capacity rights to an existing project; "LRTP" names a MISO long-range transmission project. For PJM rows, MW is the figure in the megawatt column of PJM's public queue export; PJM also tracks maximum facility output and capacity rights separately, so a project's study documents can show a different number. 5 target in-service dates below have already passed while the request is still open: operators keep the developer's last reported date until the developer changes it, so a past date means the schedule slipped, not that the project was built.

What can Saline County require of a project?
Illinois law sets the ceiling: Saline County must approve a commercial wind or solar project that meets the state standards, must finish its public hearing within 60 days, and may not ban them in agricultural or industrial zones (55 ILCS 5/5-12020); battery storage has had its own statewide standards since June 1, 2026 (55 ILCS 5/5-12024). Land inside a city or village falls under municipal zoning instead.
Local rules: as of October 17, 2026, we found no 2024–2026 county board action on solar, wind, or battery storage posted on Saline County's website or reported by local news. That does not mean the county has no ordinance: the state standards above apply everywhere, and the county zoning office can say whether a local ordinance or special use process exists.
