Common questions about power in Hinds County
How long does it take to get power for a data center in Hinds County, MS?
The median wait for a project still in the interconnection queue in Hinds County is 1.1 years. Across the US, most large loads are quoted three to seven years depending on the market and whether network upgrades are needed. 2 projects in Hinds County have reached energization and 13 were withdrawn, so the withdrawal rate here is a better guide to risk than any single quoted timeline.
How much capacity is available in Hinds County, MS?
150 MW is currently requested across 1 active interconnection requests, and 546 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.
