The SAVRN reference set

Seven references, one system

Capital, delay, policy, water, grid, permits and scarcity are one system seen from seven sides. Each reference is primary-sourced, refreshed on a schedule, and links into the others, so a project can be followed from the money committed to the docket that stopped it.

Capital Atlas
Who is funding AI data centers: capital providers, named sites, financing transactions, and the blocked-and-delayed record, state by state and company by company.
Open the atlas →
Delay Watchlist
Project-level slippage: named projects, jurisdictional actions, utility and federal dockets, SEC disclosures, and the interconnection queue.
Open the watchlist →
Moratorium Tracker
The policy layer: every state measure and local moratorium mapped and cited, with one page per state.
Open the tracker →
Water Tracker
Every federal, state, local and interstate water measure that touches a data center, plus a fifty-state water ledger.

Grid Operator Watchlist
ERCOT, PJM, MISO, CAISO, SPP, NYISO, ISO-NE and FERC: the large-load rules, filings and queue positions that decide whether a site can energize.

SAVRN Scarcity Tracker
Eleven primary-sourced indicators of AI infrastructure scarcity, one composite index, read against the token index, SAVRN's own cost basis and the frontier ceiling.
