Mississippi data centers: what the public record shows.

These notes name selected records, say which kinds of public evidence were checked and show what remains missing. They do not add anything to the published counts.

• economic development incentives — Checked
  • MDA publishes no roster of enterprises certified under the Data Center Enterprises exemption, so certified recipients could not be enumerated.
  • No MDA project file, incentive agreement or Major Economic Impact Authority award document was reached.

  Selected records

  • Amazon Web Services plans to invest $10 billion, creating 1,000 jobs to establish data center complexes in Mississippi · Mississippi Development Authority

  • Compass Datacenters project generates $10 billion investment in Lauderdale County · Mississippi Development Authority
• utility commission large load — Partly checked
  • The PSC CTS document portal (ctsportal.psc.ms.gov) presents a connection error and could not be opened by the available access methods, so no docket filing text was read.
  • No 2026 monthly utility docket calendar was located at the psc.ms.gov file path pattern; only the October 2025 calendar was read, so 2026 dockets are unexamined.
  • The subject of the Cosmos Project filing was not established; it may or may not be a data center load.
  • Mississippi Power large-load tariffs and any Compass Datacenters service agreement were not searched.

  Selected records

  • Mississippi Public Service Commission Utility Docket for the regular meeting of October 16, 2025 · Mississippi Public Service Commission

  • No MDEQ permit number, agency interest number or permit document was obtained for any research lead in the current research record.

  Selected records

  • MDEQ enSearch Online (agency interest and permit search portal) · Mississippi Department of Environmental Quality
• municipal planning assessor gis — Partly checked
  • No Mississippi county or municipal planning, zoning, minutes or assessor record was opened, so no research lead in the current research record carries a verbatim parcel ID, plat number or case number.
  • Madison County, Rankin County, Lauderdale County, Warren County and Hinds County land-use files are entirely unexamined.
• tax abatement development agreements — Partly checked
  • The statutory text could not be read: the Mississippi Legislature's bill status host presents a connection error, and the Justia mirror could not be retrieved during review.
  • No executed certification, fee-in-lieu agreement or county development agreement was located for any Mississippi data center.

  Selected records

  • No colocation operator page was consulted for Mississippi.

  Selected records

  • Compass Project Generates $10B Investment in Lauderdale County · Compass Datacenters
• open datasets directories — Checked
  • No commercial directory was consulted, so Mississippi colocation and carrier facilities are not represented at all in the current research record.
  • The crypto-mining exclusions are recorded only in this finding, not as research leads, so the current published record does not include the Greenidge Columbus cancellation.

  Selected records

  • The Saxum withdrawal rests entirely on a search-result summary; nothing was read verbatim and no City of Jackson planning file was reached.
  • No sweep was performed for closed, demolished or renamed Mississippi data centers.
  • The cancelled Greenidge Columbus site is crypto mining and was excluded from scope rather than preserved as a research lead.
• news and other discovery — Partly checked
