Common questions about power in Lee County
How long does it take to get power for a data center in Lee County, AR?
The median wait for a project still in the interconnection queue in Lee County is 2.5 years. Across the US, most large loads are quoted three to seven years depending on the market and whether network upgrades are needed. 6 projects in Lee County have reached energization and 8 were withdrawn, so the withdrawal rate here is a better guide to risk than any single quoted timeline.
How much capacity is available in Lee County, AR?
515 MW is currently requested across 2 active interconnection requests, and 985 MW has actually been built. A queued megawatt is a request, not deliverable capacity — most queued projects are never built. For deliverable offtake capacity at a specific substation you need a utility study, not a queue.
Is Lee County, AR a good site for a data center?
This page gives you the power half of that answer: what is queued, what has been energized, how long the wait runs, and which large load interconnection requests are already recorded nearby. The other half — the state policy position, moratoriums and large load tariffs — is on our Arkansas policy page.
Where does the data on this page come from?
The interconnection queue published by the transmission providers serving Lee County — MISO — parsed and normalised by Watt Street. Every figure carries the date it was true. Data as of 14 October 2026.
