On average DC Readiness, the top five states are Georgia (57.1), South Carolina (57.1), Tennessee (57.0), Delaware (56.9), Connecticut (56.7), against a national average of 53.2. 29 of 51 states beat that average. Indiana has the most candidate sites (8,629), followed by California (8,490). The shortest average interconnection-queue wait is in Montana (1.1 yrs); the national average is 4.2 years and the longest is in California (7.6 yrs).
How are candidate sites split across grid regions and land types?
By grid operator, PJM holds 31,769 (22%), MISO holds 31,047 (21%), WECC holds 24,461 (17%), SERC holds 21,546 (15%), SPP holds 16,814 (11%), CAISO holds 7,921 (5%), ISO-NE holds 5,817 (4%), ERCOT holds 4,035 (3%), NYISO holds 2,860 (2%) of the 147,272 sites. By land type, Substation-Adjacent 38,820, Industrial 35,788, Former Mine 26,205, Greenfield 18,112, Federal Excess 17,528, Manufacturing 7,657, Shovel-Ready 2,365, Brownfield 771, Military BRAC 26. Substation-Adjacent sites have the highest average readiness score (57.5); federal excess sites the lowest (47.5).
What infrastructure data sits behind the scores?
Every candidate site is scored against the infrastructure around it. The catalog of 2,442 existing datacenters is most concentrated in Virginia (379), Texas (268), Oregon (168); Ashburn, Virginia alone has 66. The 1,388 internet-exchange and colocation facilities from PeeringDB have a median of 2 connected networks each. Of 75,328 HIFLD substation points, 16,654 carry a station name; the rest are unnamed points, line taps, risers and dead-ends. Retired power plants and EPA-listed brownfields (2,085) are listed separately as reuse candidates.

How scoring works
DC Readiness is a 0–100 weighted blend of fourteen factors — power (20%), speed-to-power (20%, scored on market interconnection speed; Texas scores high, though ERCOT has paused energizing new datacenter loads of 75 MW or more since August 2026), fiber (12%), energy cost (10%), and smaller weights for water, hazard, buildability, labor, existing-datacenter ecosystem, land, construction cost, gas pipeline, tax, and climate. Scores are screening estimates from public data sources; catalogued capacity is a theoretical aggregate, not deliverable power. Read the full methodology →
Frequently asked questions
What is GridCensus?
GridCensus is a datacenter site-selection screening tool. It scores 147,272 candidate locations across the United States on power, speed-to-power, fiber, water, and hazard, using public infrastructure data.
How many datacenter sites are scored?
147,272 candidate sites across all 50 states and DC, spanning nine site types and nine ISO/RTO regions.
What is 'speed-to-power'?
Speed-to-power is how quickly a site can be energized — driven by proximity to existing transmission, substation adjacency, and interconnection-queue dynamics.
Are the scores official capacity figures?
No. Scores are screening estimates from public data, and catalogued candidate capacity is a theoretical aggregate of per-site estimates — not deliverable power. See the methodology page.
Which state scores highest for datacenter development?
Georgia has the highest average DC Readiness score (57.1 of 100) across its candidate sites, followed by South Carolina (57.1). The national average is 53.2.
How many existing datacenters does GridCensus track?
2,442 operating US datacenter facilities, one record per facility. Virginia has 379, Texas has 268, Oregon has 168 — the three largest state counts.
Where does the internet-exchange and substation data come from?
Internet-exchange and colocation facilities (1,388) come from PeeringDB; substations (16,654 with a station name) come from HIFLD electric substation and transmission-line data; retired power plants and brownfields (2,085) come from EIA-860 and EPA records.
