William Hinkle, Eversource spokesman, said Eversource is obligated by law to respond to all developer proposals and has no role in determining whether projects are allowed to interconnect if they receive required approvals
Bow Data Center (350 MW)
An unnamed company asked Eversource to assess a potential 350 MW data center facility in Bow, and Bow is reported to be in talks to become the site of a new hyperscale data center. It is reported, as reported September 1, 2026.
How much water it would use and who would use it have not been disclosed.
How to read this page. Every fact links to the source it rests on; a number in brackets is its place in the source list. A figure no source gives reads Not disclosed, and nothing is estimated. Where sources give different figures, each is shown with who gave it, and another source's figure never stands in for the record's own. Entries are added and never overwritten; corrections are listed under What happened.

The developer's figure is what the company said; what a permit allows is the ceiling a permit sets; measured means observed. Water is in gallons a day or a year, whichever the source stated; a tax claim given as a range shows both ends, each linked to the source that gave it.
Still not public, and where it would show up
The record adds each the day a source gives it. Why these documents.
- Water useA state water right filing or a water supply agreement.
- Who would use itA lease announcement or a tenant named in a filing.
- Who is behind itA land record, a zoning application or a company's own announcement.
- Jobs and taxAn incentive agreement, a county's economic development filing or a fiscal note.
