The market exhibits a structural power imbalance: the excess-power score of 35/100 signals oversupply relative to demand absorption, while the constraint score of 57/100 indicates meaningful infrastructure friction. This combination reflects a market where supply capacity outpaces tenant demand and grid infrastructure poses operational challenges to new or expanded deployments.\n\n**Rochelle:** Rochelle presents a structurally constrained market ill-suited for capital deployment. Four tracked facilities operate across a fragmented operator base: ALLSTATE DATA CENTER (1 site), Meta (1 site), and Rochelle Municipal Utilities (1 site) each hold single assets, with one additional facility unattributed. The DCPI assessment registers a constraint score of 51/100 paired with excess-power of 35/100\u2014a combination that signals fundamental infrastructure misalignment rather than cyclical underperformance.\n\n**Westmont:** Westmont's data center market remains deeply constrained and inactive. Six tracked facilities operate in the region, with Equinix controlling a dominant position across four of these sites (three under \"Equinix\" branding and one under \"EQUINIX LLC\"), alongside a single facility operated by UChicago Argonne LLC. The market has recorded zero recent deal activity, signaling a freeze in transaction momentum that extends across both acquisition and lease markets.","rationale":"Aggregated from per-market deep-dive narratives.","verdict":"AVOID","word_count":211},"paywall":{"blurb":"ISO Breakdown, Transmission Build-Out, State Policy / Tax Incentives, Top Operators, and M&A activity are unlocked with the DC Hub plan with every tool, all states.","checkout_url":"/pricing?utm_source=state_brief","required_tier":"PRO"},"policy":null,"redirect_to":null,"requested":"illinois","state":"illinois","state_code":"IL","state_name":"Illinois","tier":"FREE","top_markets":[{"brief_url":"/markets/elk-grove/brief","computed_at":"2026-10-27T12:37:12.320847+00:00","constraint_score":57.1,"excess_power":35.3,"iso":"PJM","name":"Elk Grove","slug":"elk-grove","state":"IL","verdict":"AVOID"},{"brief_url":"/markets/rochelle/brief","computed_at":"2026-10-27T12:37:23.143865+00:00","constraint_score":51.8,"excess_power":35.2,"iso":"PJM","name":"Rochelle","slug":"rochelle","state":"IL","verdict":"AVOID"},{"brief_url":"/markets/westmont/brief","computed_at":"2026-10-27T11:20:23.570306+00:00","constraint_score":57.5,"excess_power":35.2,"iso":"PJM","name":"Westmont","slug":"westmont","state":"IL","verdict":"AVOID"},{"brief_url":"/markets/wood-dale/brief","computed_at":"2026-10-27T12:37:17.402547+00:00","constraint_score":57.3,"excess_power":35.2,"iso":"PJM","name":"Wood Dale","slug":"wood-dale","state":"IL","verdict":"AVOID"},{"brief_url":"/markets/franklin-park/brief","computed_at":"2026-10-27T12:33:58.763218+00:00","constraint_score":57.6,"excess_power":35.1,"iso":"PJM","name":"Franklin Park","slug":"franklin-park","state":"IL","verdict":"AVOID"},{"brief_url":"/markets/mount-prospect/brief","computed_at":"2026-10-27T12:37:14.310990+00:00","constraint_score":57.6,"excess_power":35.1,"iso":"PJM","name":"Mount Prospect","slug":"mount-prospect","state":"IL","verdict":"AVOID"},{"brief_url":"/markets/chicago/brief","computed_at":"2026-10-27T12:31:29.326170+00:00","constraint_score":56.0,"excess_power":35.0,"iso":"PJM","name":"Chicago","slug":"chicago","state":"IL","verdict":"AVOID"},{"brief_url":"/markets/itasca/brief","computed_at":"2026-10-27T12:33:34.183818+00:00","constraint_score":57.8,"excess_power":35.0,"iso":"PJM","name":"Itasca","slug":"itasca","state":"IL","verdict":"AVOID"},{"brief_url":"/markets/oak-brook/brief","computed_at":"2026-10-27T12:34:27.424581+00:00","constraint_score":57.8,"excess_power":35.0,"iso":"PJM","name":"Oak Brook","slug":"oak-brook","state":"IL","verdict":"AVOID"},{"brief_url":"/markets/northlake/brief","computed_at":"2026-10-27T12:33:37.593535+00:00","constraint_score":58.7,"excess_power":34.6,"iso":"PJM","name":"Northlake","slug":"northlake","state":"IL","verdict":"AVOID"},{"brief_url":"/markets/aurora/brief","computed_at":"2026-10-27T12:32:23.964114+00:00","constraint_score":59.5,"excess_power":34.3,"iso":"PJM","name":"Aurora","slug":"aurora","state":"IL","verdict":"AVOID"},{"brief_url":"/markets/elk-grove-village/brief","computed_at":"2026-10-27T12:32:05.249886+00:00","constraint_score":59.8,"excess_power":34.1,"iso":"PJM","name":"Elk Grove Village","slug":"elk-grove-village","state":"IL","verdict":"AVOID"}],"transmission":null}
