Disclosed figures

2 MW power

Power, water, jobs and tax, summed only where a data center disclosed the figure; what each facility is for; how each is cooled. Nothing here is estimated.

Power, water, jobs and tax

Figure	Disclosed total	Disclosed	Without a figure	Basis
Power	2 MW	1	0	1 the developer's figure
Water, stated per day		0	1
Water, stated per year		0	1
Permanent jobs		0	1
Tax each year		0	1

A blank total means no record disclosed the figure; the count without one says how many.

Summed only where a record disclosed the figure; a record with no figure adds nothing and is counted as not disclosed. Water is summed per day and per year separately, as the sources stated it, and never converted. A tax claim given as a range is summed at both ends.

By what the facilities are for

Use	Records	Power	Water	Jobs	Tax each year
No stated use	1	2 MW

A blank cell means no record with that use disclosed the figure.

A record that lists several uses counts once under each. Each cell is the sum over the records with that use, disclosed rows only.

What the facilities are for

No source on file states what any of the 1 tracked facility in Washington County is for.

How the facilities are cooled

No source on file states how any of the 1 tracked facility in Washington County is cooled.
