Arba Solar Energy Storage is a hybrid solar and battery energy storage system located in Greene County, North Carolina. The plant, which began operating in 2023, has a total capacity of 10.1 MW and is owned and operated by North Carolina El Member Corp. It consists of two generators utilizing both solar photovoltaic and battery technologies. The battery energy storage system (BESS) has a storage capacity of 10 MWh, a duration of 1.96 hours, and uses lithium-ion battery (LIB) chemistry. The solar component uses single-axis tracking.
The plant's latest annual generation was 5,994 MWh, resulting in a capacity factor of 6.8%. Arba Solar Energy Storage operates within the Duke Energy Progress East balancing authority and the SERC NERC region. It ranks as the 8th largest solar facility out of 36 in North Carolina, and 741st nationally out of 1205. Financial data is available for the plant via LBNL Solar.

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 the Southeast Energy Exchange Market (SEEM). SEEM is a bilateral exchange — no public nodal pricing.
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.
