Located in Hawaii County, Hawaii, the Mauna Loa Macadamia Nut power plant is a 1.3 MW hybrid facility consisting of solar photovoltaic generation paired with battery energy storage. The plant, owned and operated by Macadamia Nut Road Solar Project 2019, began operating in 2021 and utilizes single-axis tracking for its solar panels. The facility is connected to the Hawaiian Electric Co Inc balancing authority. It ranks 20th out of 20 power plants in the state and 1179th out of 1205 nationally.
The plant's battery energy storage system (BESS) has a capacity of 1.3 MWh and a duration of 2.6 hours, utilizing lithium-ion battery chemistry (LIB). In its most recent year of operation, the plant generated 1350 MWh of electricity, achieving a capacity factor of 11.8%. The plant has two generators and is fueled by MWH. There has been one news article about the plant, categorized under hazards.

This plant is in a bilateral market territory without organized wholesale pricing. Nodal pricing data is not 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.
