How to read the map.
Gridwatch is a US data center registry you navigate as a map. This page is the manual: what a pin is, how to find and filter, what a facility record holds — and, most of all, how to read the numbers without reading more into them than the data supports.
What you're looking at
Every pin is one facility, and every facility is a place verified in a county's own records. The pin sits on the parcel the building occupies — not on a geocoded address, which lands on a road rather than a lot. When you look at the map, you are looking at the registry itself: one point per verified site.
The map opens on the United States because that is what Gridwatch verifies today. What is here, and what isn't yet, is covered at the end of this page.
Reading a pin
A pin's color is its status — where the project sits on the path from rumor to running. Status is a claim we can source, and each word means a specific thing:
- Rumored — a sourced signal that something is coming, short of a filed plan.
- Proposed — announced or filed: a rezoning, a development application, a public plan.
- Permitted — a building permit has actually been issued at the address. A rezoning approval is not this.
- Under construction — permitted and being built.
- Operating — live.
- Cancelled — a real project, sourced to a real parcel, that died. It stays on the record.
The registry deliberately carries early-stage projects. A rumored or proposed pin is not a lesser fact — it is an accurately-labeled one. The status is the claim; the color only lets you see it at a glance. The filter panel is the key.
Finding what you want
Three tools narrow the full map to the facilities you care about.
- Search. The bar matches facility, operator, city, or state, and suggests as you type. Pick a result to fly straight to it.
- Filters. Narrow by status, by state, by a minimum capacity, and by operator type — hyperscaler, colocation, enterprise, or undisclosed. The map and the count update as you go.
- Map or list. The same filtered set, two ways: pins on the map, or a sortable table. Switch with the Map / List toggle.
Opening a facility
Select a pin — or a row — and the facility opens: its operator and type, its address and coordinates, the power and water it discloses, its timeline, and the sources behind each fact.
Where a field reads — or not disclosed, that is a blank — not a zero, and not a guess. A field is left empty rather than filled with a number that has no source. The empty field is telling you the truth about what is on the record.
Reading the capacity number
The header shows the number of facilities in view and, beside it, a gigawatt figure labeled disclosed. The facility count is solid. The gigawatt figure is not a total — it is a floor, summed across only the facilities that actually publish a capacity, which are the minority. Most facilities carry no public capacity figure at all, so their megawatts are simply not in that number.
Read it as “at least this much, from the sites that told us” — never as the total power of everything on the map. That is why the figure always says disclosed, and why hovering it shows how many of the visible facilities it is actually built from.
Compare and export
Add facilities to a comparison — up to three — to see them side by side. And with a Pro plan, the facilities on your watch list export to CSV once a week, so the set you are tracking leaves with you. Bulk access to the whole registry is a licensed Enterprise product — that is a sales conversation, not a self-serve download.
Alerts, and the Watch list
Alerts let a Pro account follow facilities and get email when a record changes.
The Watch list is a different thing, and worth understanding. A watch item is a sourced signal — a county moratorium moving, a site being marketed — that has no parcel yet. Because it has no parcel, it never appears as a pin on the map. And because it is not verified to a primary record, it is not part of a county's certification. It is a lead on the record: kept honest, and kept separate.
What's here, and what isn't yet
Gridwatch is US data center intelligence. It launches with Florida certified — all 67 counties, every county worked to a determination, whether that meant registering facilities or certifying that it has none. Other states follow, one at a time, to the same standard.
So read a thin state carefully: it may genuinely have little, or it may not yet have been worked. A missing pin means we have not verified one there — not that none exists. As certification rolls out, the map fills in.
When you need more than the map
If you need programmatic or bulk access, want a state or market prioritized, or want to license the registry itself, that is a conversation we're glad to have.
