What does bind large loads in Mississippi
A moratorium is only one way a data center gets stopped. The grid operator decides whether it can connect at all, and on what terms. Mississippi sits in 2 footprints.
Entergy Mississippi (Jackson, central/west) in MISO; TVA serves northeast MS and Mississippi Power (Southern Co) serves the Gulf Coast, both non-RTO.

How to read this page
In force = a moratorium, siting restriction, or tax-incentive rollback that is currently enacted, by statute or executive order. Paused = a temporary hold on new incentives or applications. Proposed = introduced and still pending. Failed / vetoed = died in committee, was voted down, or was vetoed.
This page is generated from the same primary-sourced dataset as the national U.S. Data Center Moratorium Tracker and is re-checked on the same weekly cycle, whether or not anything changed. Legislative status changes quickly; it is informational, not legal advice. Spot something out of date in Mississippi? Tell us.

Why Mississippi is pushing back
The objections repeat from state to state: strain on the electric grid, water drawn for cooling, and the sense that a facility takes local resources without giving much back. SAVRN builds AI factories designed around those three objections: on-site power that does not lean on the public grid, direct-to-chip cooling that does not consume municipal water, and a training institute that puts local people to work inside the building.
