Power & your bill

150 MW of new demand — roughly a city of 120,000 homes.

Large new loads can raise transmission and capacity costs that land on every ratepayer. Residential power in NY is 29.4¢/kWh, up 14.6% year-over-year. (MW→homes is a rough ~800/MW planning figure.)

Process

Demand a full, public review — not a rubber stamp.

Ask for an independent noise study, a water-and-power impact assessment, enforceable conditions (setbacks, hours, cooling type), and that the record stays open for written comment. Procedural shortcuts have voided approvals elsewhere.

Municipal water

No service area

self-supplied or unmapped

The closest existing grid infrastructure and the municipal water system this location sits in — the same constraints the buildout model screens on (it won't site a campus more than ~2 km from a substation or ~5 km from municipal water). Distances are straight-line to public HIFLD/EPA features, not a metered connection.

Tax breaks & subsidies

source: Good Jobs First / GASB 77

No per-deal tax break is linked to this site yet. No state discloses the recipient of a data-center abatement at the facility level, so per-site deals are rare in the public record. If you have a development agreement or board resolution for this site, send it to us.

Water use

No public record of this facility's water use. We check state withdrawal reporting for self-supplied sites; municipally supplied sites only become visible through a public-records request to the local water utility — a per-facility request tool is coming. If you have a utility document for this site, send it to us.

EPA permits & violations

source: EPA ECHO

No reported violations as of last sync.

Nearest school

source: HIFLD / NCES

The nearest public school, Trumansburg Elementary School in Trumansburg, is 4.6 mi from this site (389 students).

Schools are sensitive receptors for the noise, backup-generator exhaust, and traffic a large data center brings. Straight-line distance to the nearest public school (HIFLD/NCES, US public schools only).
