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 A campus can exist without appearing in a filing we read, and a filing can be out of date.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
17 data center campuses are on record in King County, 16 of them operating.
| Status | What it means | Campuses |
|---|---|---|
| Operating | Recorded as in service. | 16 |
| Permitted | A permit or approval is on record. Construction may not have started. | 1 |
Capacity
Megawatt figures come from two very different places and are never added together. No government record in this county states a capacity. A further 15 MW is claimed by commercial directories across 2 of 17, which we repeat with attribution and do not treat as measured.

A campus shown as county only has a record that names King 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 |
|---|---|---|---|
| Puget Sound Energy Inc | Investor Owned | 1,091,599 | 14.63 cents/kWh |
| City of Seattle - (WA) | Municipal | 459,964 | 14.09 cents/kWh |
| City of Tacoma - (WA) | Municipal | 180,357 | 10.81 cents/kWh |
| PUD No 1 of Chelan County | Political Subdivision | 42,120 | 3.67 cents/kWh |
| Bonneville Power Administration | Federal | not stated | not stated |
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 WA 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.
