Conflicts and open questions

  • Under 50 MW (no MW reported; 5-acre site, eight modular units). Kept because it is contested and confirmed.
  • KY3 (Sept. 2026) reports that the developer suing Benton County over its moratorium (NSI6 LLC) is also behind the Rifle Range Road site, and that the same company is suing Springfield over its moratorium for a site at 2900 S. National Ave.
