What stands out in Peoria County
By capacity, wind leads in Peoria County with 1,500 MW across 5 projects, followed by battery storage (2 projects, 600 MW). The largest is queue number J3860, a 500 MW wind request in the MISO queue, in study (Phase 1), filed Jan 2025, with a target in-service date of Apr 2030. Of the 7, 7 are still in study. All of them are in the MISO queue, which covers the Ameren Illinois side of the state. Ameren Transmission Company Of Illinois is the transmission owner named most often (5 of 7). The requests were filed between Mar 2022 and May 2025. Target in-service dates for those not yet under construction span Oct 2025 to Apr 2030; 1 of them has 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the table: the queue number is the operator's ID for the request (MISO J-numbers, PJM AE/AF/AG-numbers); operators do not publish developer names in these files.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. 1 target in-service date below has 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 Peoria County require of a project?
Illinois law sets the ceiling: Peoria 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.
Recent local action: On April 9, 2026 the Peoria County Board voted 15–0 to grant a special use permit to Chaberton Solar Seneca, LLC for a 5-megawatt solar energy generation facility on Dietrich Lane in Bartonville near Limestone High School. (WCBU (Peoria Public Radio))
