Conflicts and open questions

  • Coordinates approximate, placed about 1 to 2 miles west of Ellendale as reported (Jamestown Sun 2023; Valley News Live 2026); not a parcel address.
  • ELN-01 hosting facility and the Polaris Forge 1 HPC buildings are treated as one campus because they are adjacent and reported as one site. The 2023 10-K said APLD ELN-01 owned 40 acres there; total campus acreage was not found.
  • Crypto-mining (bitcoin) hosting is part of this campus.
  • Ellendale's taxable value was $3.5 million at the end of 2025; the mayor expects about $1.4 million in city property tax revenue next year (ND Monitor; Valley News Live, Sept. 2026).
  • The annexation ordinance itself was not opened; annexation in early 2025 rests on North Dakota Monitor (Sept. 2026) and the Grand Forks Herald (June 2025).
  • Local concerns reported: truck traffic, worker influx, noise from the air-cooled mining facility (sound barriers built) and water hauled for initial cooling fill.

The full record

Status note
The first 100 MW HPC building began operating in October 2025 and the second (150 MW) was fully delivered Oct. 1, 2026; a third 150 MW building is under construction for 2027, and the 180 MW crypto-mining hosting facility on the same campus runs at full capacity.
Power note
400 MW is the critical IT load leased to CoreWeave across three HPC buildings (100 + 150 + 150 MW). The adjacent ELN-01 crypto-mining hosting facility adds 180 MW of utility load. The company says the campus is designed to grow to about 1 GW. The Grand Forks Herald (June 2025) cited 250 MW of IT plus 82 MW for cooling and other operations for the first two HPC buildings.
