Across the 48 US states the index ranks, Arizona leads NexPhase's DC Site Intelligence ranking at 9.6/10, followed by Texas and Nevada. The ranking combines interconnection queue activity at each state's substations with retail load growth.

Not ranked: Alaska and Hawaii (not enough queue data).
What it measures. The index ranks 48 states on three inputs, from measured public data only. Queue activity: the average interconnection queue activity at the state's substations where generation has filed to connect (megawatts requested, number of requests, share still active and voltage), a proxy for developer interest in the grid there. Queue depth: how many substations show strong or moderate queue activity. Load growth: how fast retail electricity sales have grown (historical).
What it does not measure. It does not measure transmission capacity or load-serving capacity. Queue activity shows where generation developers want to connect, not spare room on the grid; a heavily queued substation can have the least room left. Whether a utility can serve a new large load at a given site takes a utility service availability study.
How to use it. Use it to pre-screen markets before utility outreach, not as a siting recommendation. For any state, confirm large-load service timelines with the utility.
How it is scored. Each state gets a score from 1 to 10. A state with no retail sales data is scored on the other measures, so missing sales data never counts against it. A state with no interconnection queue data is not ranked (not enough queue data): Alaska and Hawaii. Scores are recomputed when the queue data is refreshed, weekly.
From public interconnection queues, utility filings and federal energy data.
