Copia Power Belmont Energy Center (Harquahala Valley solar + data center campus)

Copia Power Belmont Energy Center (Harquahala Valley solar + data center campus) is a planned data center in Maricopa County, AZ. Salt Lake City-based Copia Power filed with Maricopa County to rezone ~3,100 acres near Tonopah for the Belmont Energy Center: ~2,860 acres of utility-scale solar plus ~320 acres for gas generation, battery storage and data centers, within a larger 30,000-acre digital-infrastructure campus in Harquahala Valley owned by Copia and investor partners. Rezoning was pending as of Aug 2026; no tenant or MW disclosed. Distinct from Copia's Griffin Energy Project in Pinal County that feeds the W Holdings campus near Maricopa.
