notes: >-
  Located northeast of Sioux Falls, being annexed into the city (Minnehaha
  County, SD); locality set to Sioux Falls given the annexation. Status set to
  permitted on the basis of the Oct 2025 city approval to annex ~160 acres;
  this is a land/annexation approval rather than a construction permit, so the
  classification is provisional pending confirmation of build permits.
  Developer is "Gemini Data Center SD LLC" (a likely special-purpose entity)
  with no operators.yml entry — developer field omitted; Gemini Data Center SD
  LLC needs an operators.yml entry (may be an alias of an as-yet-unidentified
  hyperscaler). capacity_mw 500 and land_acres 160 are reported as approximate.
  Single-source support throughout, hence medium confidence.
