Live grid snapshots for every major US ISO and balancing authority — interconnection queue depth, current load, firm capacity, fuel mix, and the headroom that determines whether a 200 MW data center can land in this study cycle.
13 states + DC · largest US grid operator
Texas-only · 90% of state load
California + parts of NV · highest renewables share
15 states · Manitoba · largest geographic footprint
NY State · constrained zones drive premium pricing
6 New England states · winter-peaking gas exposure
14 states · highest wind penetration in US
Every data-center site-selection question eventually narrows to one ISO. The ISO sets the rules for interconnection studies, the queue you wait in, the capacity-payment regime you'll be exposed to, and — through fuel mix and headroom — the marginal cost of every megawatt-hour you consume. DC Hub ingests live operator data from all seven major US ISOs (PJM, ERCOT, CAISO, MISO, NYISO, ISO-NE, SPP) plus three international peers (AESO, Hydro-Québec, Nord Pool) and recomputes per-region capacity, queue depth, and headroom on a continuous cycle.
The per-ISO signals feed two derived surfaces: the Data Center Power Index (DCPI) — a 0–100 score that ranks 200+ US markets as BUILD, CAUTION, AVOID, or LOW_SIGNAL — and the grid intelligence dashboard, which exposes the underlying capacity-factor and queue-position data for direct download. For market-level analysis, every DC Hub market page links back to its serving ISO so the site-selection and energy-intelligence views stay coupled.
