Part of the [North American Data Center Capital Atlas](https://savrn.com/data-center-capital-atlas), refreshed every Tuesday, Thursday and Saturday. Site commitments overlap reported capital expenditure and overlap one another, so this page shows each figure as its source states it and never adds them into a single deployment number. Informational, not investment advice. 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. Delay Watchlist Project-level slippage: named projects, jurisdictional actions, utility and federal dockets, SEC disclosures, and the interconnection queue. [Open the watchlist →](https://savrn.com/data-center-delay-tracker) Moratorium Tracker The policy layer: every state measure and local moratorium mapped and cited, with one page per state.

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. Open the watchlist → Permits and Power Development Data center and substation permits, large loads in the interconnection queues, and the power plants planned to serve them, refreshed hourly from public records.
