Watchtower
Screening tells you where to look.
Watchtower tells you when things change.
A datacenter deal lives or dies on signals that move while you're not looking — a regulatory gate trips, a constraint starts binding, a hyperscaler breaks ground nearby. Pin any of GridCensus's 147,272 scored sites (or any address you're vetting) and we re-scan its siting signals on a schedule, then email you only when something changed.
How it works
- 1 · Pin
Hit Watch on any site profile, /find result, or vet-a-site read. Free accounts watch one location; Pro watches 25.
- 2 · Scan
We re-assemble the full signal set on a schedule — nightly on Pro, weekly on free — and diff it against the last snapshot.
- 3 · Hear only signal
A digest lands when something changed. High-severity changes (score drops, regulatory flips) alert immediately.
What gets watched
The 0–100 score and its sub-scores. A rescore that moves your site ±5 points is a high-severity alert.
Favorable / Moderate / Restrictive at your target build size. A new moratorium or a tariff gate tripping at your MW emails you immediately.
Shifts in the top transmission bottlenecks from priced SCED constraint data. Statewide today; per-site as crosswalks land.
New frontier AI campuses announced within 75 miles of your site — owner, off-taker, and power where public.
New operating datacenters and hyperscaler presence appearing near your location.
New local headlines on datacenters, large loads, substations, and interconnection for your site's area.
Every signal is built from public, independently checkable data — the same sources shown in our methodology. We don't claim to know private utility negotiations, and we say so rather than fake precision. Watch snapshots also accumulate a per-site history — readiness over time — that no point-in-time screen can give you.
Free watches one. Pro watches your pipeline.
Every account gets 1 watched location with a weekly scan and Monday digest — free forever, like all of GridCensus's screening. Pro ($249/mo) watches up to 25 locations with nightly scans, daily digests, immediate high-severity alerts, full event history, and the rest of the Pro catalog. Enterprise adds team seats, webhooks, and unlimited watches.
