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 →](https://savrn.com/data-center-capital-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. Open the water tracker → 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.
