Across the US, most large loads are quoted three to seven years depending on the market and whether network upgrades are needed. 1 projects in Herkimer County have reached energization and 23 were withdrawn, so the withdrawal rate here is a better guide to risk than any single quoted timeline.
How much capacity is available in Herkimer County, NY?
450 MW is currently requested across 6 active interconnection requests, and 74 MW has actually been built.
