What energy projects are proposed in Tazewell County?
The MISO and PJM interconnection queues list 13 proposed projects in Tazewell County (3 solar, 1 solar plus storage, 4 wind, 5 battery storage), about 2,164 MW in all. 2 have a signed interconnection agreement.
What stands out in Tazewell County
By capacity, battery storage leads in Tazewell County with 918 MW across 5 projects, followed by solar (3 projects, 650 MW) and wind (4 projects, 575 MW). The largest is queue number J3946, a 300 MW battery storage request in the MISO queue, in study (Phase 1), filed Mar 2025, with a target in-service date of Jun 2030. Of the 13, 11 are still in study and 2 have a signed agreement. 10 are in the MISO queue (Ameren territory) and 3 in PJM (ComEd territory), so Tazewell County straddles both grids. Ameren Illinois is the transmission owner named most often (10 of 13). The requests were filed between Jun 2020 and Mar 2025. Target in-service dates for those not yet under construction span Sep 2023 to Jun 2030; 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the table: the queue number is the operator's ID for the request (MISO J-numbers, PJM AE/AF/AG-numbers); operators do not publish developer names in these files.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 Tazewell County require of a project?
Illinois law sets the ceiling: Tazewell 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 July 29, 2026, the county board voted 17–2 to deny a 5 MW community solar permit and adopted a renewable energy ordinance with tighter wind and solar rules. (WCBU)
