PowerHouse Hillwood Joliet data center campus
litigation FERC protest filed 14 August 2026; FERC order rejecting ComEd's notice of cancellation issued 22 September 2026 (ER26-3257-000); contract dispute pending in the U.S. District Court for the Northern District of Illinois
PowerHouse Hillwood Holding ComEd service territory (FERC dispute)
ComEd cancelled the project's transmission security agreement and retail service agreement over security deposit timing; the developer raised the dispute at FERC. On 22 September 2026 FERC issued an order in Docket ER26-3257-000 rejecting ComEd's notice of cancellation of the transmission security agreement for the 1.8 GW, $20 billion Joliet campus. PowerHouse Hillwood contends it met the agreement's initial credit requirement with a $1 posting. FERC declined to assert primary jurisdiction over the contract dispute, which is pending in the U.S. District Court for the Northern District of Illinois. Chairman Laura Swett and Commissioner Lindsay See filed a joint concurrence, and Commissioners David Rosner and David LaCerte also concurred; LaCerte called the $1 letter of credit an embarrassing legal fiction.

Policy context

What governs a data center in Illinois

Illinois (statewide)state
Statewide DCEO incentive suspension (Jul 2026); statewide HB 4172 failed. C.4 floors: 600 MW (CyrusOne Sangamon); $500M+; 4 named; 11 tracked actions.
Illinois tracks 11 actions including the DCEO incentive suspension, Bloomington and Normal (May 2026), Champaign County (Apr 2026), Carbondale (Jun 2026), Logan County (lifted May 2026), and a proposed Naperville measure (Jan 2026). ComEd reported on 16 September 2026 that it signed transmission security agreements with two more data center developers, for six active agreements backed by more than $1 billion in letters of credit, and that its large-load queue fell from about 39 GW to 25 GW.

The policy layer for Illinois lives in three companion references: the Illinois Data Center Moratorium Tracker for every state measure and local moratorium on record, the Water Tracker for the water rules that touch a site, and the Grid Operator Watchlist for the large-load rules of the RTO or utility that decides whether it can energize.
