Owner data does not fully agree across sources.
EIA typically reports the operating utility, while GEM resolves to the financial owner or parent corporation. Both can be correct.

The SR McNeal facility is a 40 MW hybrid power plant located in Cochise County, Arizona. Operated by SR McNeal, LLC, the plant began commercial operation in 2023 and utilizes both solar photovoltaic and battery storage technologies. The facility consists of two generators and is fueled primarily by energy from solar, stored in lithium-ion batteries. The solar array uses single-axis tracking to maximize energy capture.
SR McNeal has a battery energy storage system (BESS) with a capacity of 20 MWh and a duration of 1 hour. In its first year of operation, the plant generated 52,776 MWh, achieving a capacity factor of 15.1%. The plant operates within the Tucson Electric Power Company balancing authority and the Western Electricity Coordinating Council (WECC) NERC region. SR McNeal ranks as the 56th largest power plant in Arizona out of 68, and 632nd nationally out of 1205. Financial data indicates a power purchase agreement (PPA) price of $23.86 per MWh, according to data from Lawrence Berkeley National Laboratory (LBNL).

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.
