What energy projects are proposed in Perry County?
The MISO interconnection queue lists 10 proposed projects in Perry County (6 solar, 4 battery storage), about 2,050 MW in all. 3 have a signed interconnection agreement.
What stands out in Perry County
By capacity, solar leads in Perry County with 1,407 MW across 6 projects, followed by battery storage (4 projects, 643 MW). The largest is queue number J2171, a 500 MW solar request in the MISO queue, in study (Phase 2), filed Mar 2022, with a target in-service date of May 2024. Of the 10, 7 are still in study and 3 have a signed agreement. All of them are in the MISO queue, which covers the Ameren Illinois side of the state. Ameren Illinois is the transmission owner named most often (7 of 10). The requests were filed between Apr 2019 and Nov 2025. Target in-service dates for those not yet under construction span Dec 2021 to Sep 2028; 7 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the table: the queue number is the operator's ID for the request (MISO J-numbers, PJM AE/AF/AG-numbers); operators do not publish developer names in these files.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. 7 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 Perry County require of a project?
Illinois law sets the ceiling: Perry 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 Perry 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.
