The Hyder II Hybrid plant is a 28 MW hybrid facility located in Yuma County, Arizona. It began operating in 2013 and is owned by Pinnacle West Capital and operated by Arizona Public Service Co. The plant utilizes both solar photovoltaic and battery storage technologies. The battery energy storage system (BESS) has a capacity of 42 MWh, providing 3 hours of duration and using lithium-ion battery chemistry (LIB). The solar component uses single-axis tracking.
Hyder II Hybrid is interconnected to the Arizona Public Service Company balancing authority within the Western Electricity Coordinating Council (WECC) NERC region. In the most recent year of data, the plant generated 32,538 MWh, achieving a capacity factor of 13.2%. The installed cost of the plant was $3,700.85 per kW. The plant is ranked 63rd out of 68 plants in Arizona and 659th out of 1205 plants nationally.

Capacity Factor
Positive values indicate net discharge (generation exceeds station load). Negative values indicate net charging. Pure battery storage plants are typically net negative due to round-trip efficiency losses.

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.
