Chevelon Butte Phase 2 is a 216 MW wind power plant located in Coconino County, Arizona. The facility began operating in 2024 and is owned and operated by AES Clean Energy, a subsidiary of AES. The plant utilizes one generator consisting of multiple onshore wind turbines. The wind turbines are manufactured by Vestas, model V150-4.5, with a rotor diameter of 150 meters and a hub height of 120 meters.
In its most recent year of operation, Chevelon Butte Phase 2 generated 525,472 MWh of electricity, resulting in a capacity factor of 27.8%. The plant is interconnected to the grid within the Arizona Public Service Company balancing authority, operating within the Western Electricity Coordinating Council (WECC) NERC region. Chevelon Butte Phase 2 is currently ranked as the third largest of four wind plants in Arizona, and 224th out of 734 wind plants nationally.

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.
