What stands out in LaSalle County

By capacity, wind leads in LaSalle County with 707 MW across 5 projects, followed by solar (3 projects, 368 MW) and battery storage (3 projects, 150 MW). The largest is queue number AI2-180, a 191 MW wind request in the PJM queue, in study, filed Feb 2023, with a target in-service date of Feb 2023. Of the 11, 10 are still in study and 1 is under construction. All of them are in the PJM queue, which covers the ComEd side of the state. The requests were filed between Jan 2018 and Feb 2023. Target in-service dates for those not yet under construction span Feb 2023 to Mar 2025; 10 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the table: the queue number is the operator's ID for the request (MISO J-numbers, PJM AE/AF/AG-numbers); operators do not publish developer names in these files.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. 10 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.

Scroll the table sideways to see every column.

What can LaSalle County require of a project?

Illinois law sets the ceiling: LaSalle 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 10, 2025 the La Salle County Board passed a resolution, 21–5, asserting the county's right to control siting approval for wind and solar projects and urging the General Assembly to repeal Public Act 102-1123. In February 2025, 17 of 29 members abstained or voted present on a 76-acre Utica Township solar farm, which passed with eight yes votes. (Shaw Local (NewsTribune))
