Data centers on record in Napa County, CA

Every campus this county has a public record for, with its status, who it is on record to, and the document each claim rests on. Compiled Sep 17, 2026.

On record

Operating

Withdrawn or rejected

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 A campus can exist without appearing in a filing we read, and a filing can be out of date.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.

1. What is on record

2 data center campuses are on record in Napa County, none of them recorded as operating.

Status	What it means	Campuses
Permitted	A permit or approval is on record. Construction may not have started.	2

Capacity

Megawatt figures come from two very different places and are never added together. No government record in this county states a capacity. No directory claims a capacity here either.

2. Every campus in Napa County

Campus	Status	On record to	Where	Capacity	Sources
Kaiser Permanente	Permitted	Owner not independently traced Listed as Prime Data Centers by DataCentersExposed. We have not verified that against a filing.	2600 NAPA VALLY CRPRT DR	not stated	1, 2, 3
Regulus	Permitted	Owner not resolved	860 Latour Court	not stated	4

A campus shown as county only has a record that names Napa 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. 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
Pacific Gas & Electric Co.	Investor Owned	5,047,461	31.70 cents/kWh

4. 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 CA is described on the methodology page.

5. 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.
