Common questions about power in Westchester County
How long does it take to get power for a data center in Westchester County, NY?
We do not yet have a median wait for Westchester County. Across the US, most large loads are quoted three to seven years depending on the market and whether network upgrades are needed. 4 projects in Westchester County have reached energization and 19 were withdrawn, so the withdrawal rate here is a better guide to risk than any single quoted timeline.
How much capacity is available in Westchester County, NY?
0 MW is currently requested across 0 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.
Is Westchester County, NY 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 New York policy page.
Where does the data on this page come from?
The interconnection queue published by the transmission providers serving Westchester County — the utilities in this area — parsed and normalised by Watt Street. Every figure carries the date it was true. Data as of 14 October 2026.
