The Atlas power plant is a 600 MW hybrid facility located in La Paz County, Arizona. It combines solar photovoltaic generation with battery energy storage. The plant is owned by Hanwha, a South Korean company, and operated by its subsidiary, 174 Power Global Corp. The facility utilizes fixed-tilt solar tracking technology.
Atlas is interconnected to the Arizona Public Service Company balancing authority within the Western Electricity Coordinating Council (WECC) NERC region. It ranks as the 12th largest power plant in Arizona out of 47, and 40th nationally out of 514. The plant consists of 2 generators and its primary fuel source is listed as MWH.

This plant's balancing authority participates in CAISO's Western Energy Imbalance Market (WEIM). Direct nodal pricing data is not yet available.
No wholesale contracts disclosed in FERC EQR for this plant.
FERC EQR captures bilateral wholesale energy + capacity contracts ≥$1M/yr filed quarterly by jurisdictional sellers — covers renewable PPAs, thermal energy sales agreements, capacity contracts, and tolling agreements alike. Many plants don't appear: regulated-utility output flows to ratepayers via cost-of-service rather than bilateral contracts; small projects fall below the filing threshold; tax-equity-financed renewables route offtake to investors not utilities; merchant plants sell into ISO clearing markets without bilateral contracts. News-extracted buyer facts (below) may surface contracts disclosed only through announcements.
