Source-reported capacity; not metered consumption. Review underlying documents and notes. Planned capacity may include future phases and is not added to operational capacity here. The source may use facility, grid-feed or IT capacity definitions; consult the linked documents.
Coordinate precision is a source label, not an independent parcel survey. A marker does not confirm utility territory or establish an effect on residential bills.

Source notes
5319 Enterprise Dr, Lockport, NY. Built by Yahoo in 2010 (opened at 155,000 sq ft, expanded since); campus totals 409,200 sq ft / 43 acres shared with the separate H5 Buffalo II building (~0.25 mi away — see that record). H5 Data Centers acquired both Lockport buildings from Yahoo in a sale-leaseback deal that closed Dec 30, 2024 ($49M reported); Yahoo signed a 5-year leaseback and remains a tenant on-site (140 staff retained, 15 transferred to H5). Now multi-tenant Tier III colocation, though no tenants beyond Yahoo are independently confirmed. Critical power was 16 MW as of 2014; as of July 2026, the current total post-expansion had not been independently disclosed, so no capacity is recorded rather than guessed. Coordinates fall within the building footprint mapped at 5319 Enterprise Drive in OpenStreetMap, inside the area it labels 'Yahoo! Lockport Datacenter'.
Built by Yahoo on a New York Power Authority low-cost hydropower allocation of 15 MW at the outset of construction, with an additional 1 MW approved by NYPA in April 2011 for the second phase.
