This is a compilation of public records, not a register. A campus can exist without appearing in a filing we read, and a filing can be out of date. Everything here is traceable: the sources section at the back lists the document behind every claim, with the date it carried.

A campus shown as county only has a record that names St. Lawrence County but no address or coordinate we can stand behind, so it is deliberately not placed on a map or given a distance. It is still counted.

3. Local rules on record

0 of these 1 records cite a government document with a date. The rest come from press reporting collected by a third party and are marked as reported, which means we have not read the ordinance ourselves.

Jurisdiction Recorded as Evidence Date
St. Lawrence County restriction Press report Jun 1, 2026

A reported restriction is a claim we are passing on with its source, not a finding. Check the jurisdiction's own minutes before relying on it.

4. Who sells the power

From the utilities' own EIA-861 filings for 2024. A residential rate is not what a data center pays, and it is here as the one published number that lets you compare one utility to another.

Utility Ownership Customers Residential rate
Niagara Mohawk Power Corp. Investor Owned 1,532,294 16.67 cents/kWh
Town of Massena - (NY) Municipal 8,156 6.19 cents/kWh

5. How to read this

What an empty row means

A blank is written "not stated" throughout, and it means no record we hold states a value. It does not mean zero. A campus with no capacity shown may well have one; no filing we read published it.

What "on record to" means

A name appears without qualification only where a document chain gets from the site to the company: a permit, a filing, a registration. Where a commercial directory asserts an owner and nothing corroborates it, the row says so. Roughly two thirds of all owner information available for US data centers is of that second kind, and treating it as established is the single most common error in this subject.

What this is not

Not a register, not an official list, not a prediction. Data Centers Near Me is an independent compilation of records that are already public. Coverage is deeper in some states than others, and NY is described on the methodology page.

6. Sources

Every numbered source cited in section 2, in the order it first appears. Dates are the date the document itself carries where it has one, and the date we retrieved it where it does not.
