Common questions about power in Duval County
How long does it take to get power for a data center in Duval County, TX?

How much capacity is available in Duval County, TX?
3.8 GW is currently requested across 16 active interconnection requests, and 0 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.
