Located in Washington County, Arkansas, the Westside Wastewater Treatment Plant Hybrid is a hybrid power plant owned and operated by Today's Power, Inc. The plant began operating in 2019 and has a total capacity of 11 MW across two generators. The primary fuel source is listed as MWH, and the plant utilizes both solar photovoltaic technology with single-axis tracking and battery storage. The battery energy storage system (BESS) has a capacity of 13.1 MWh, a duration of 2.18 hours, and uses lithium-ion battery chemistry (LIB).
The plant operates within the Southwest Power Pool (SPP) balancing authority and the Midwest Reliability Organization (MRO) NERC region. In its latest year of reported generation, the plant produced 2,774 MWh, resulting in a capacity factor of 2.9%. The plant is ranked as the second largest of five hybrid plants in Arkansas and 733rd out of 1205 nationally. Financial data is available for the plant, sourced from Lawrence Berkeley National Laboratory (LBNL) solar data. There has been one news article published about the plant, categorized under hazards.

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.

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.
