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.

Lone Star Solar is a 132 MW hybrid power plant located in Calhoun County, South Carolina. The plant, which began operating in 2024, is owned and operated by Lone Star Solar. It utilizes both solar photovoltaic technology and battery storage. The facility has two generators and is considered the third-largest solar plant in South Carolina, and ranks 420th nationally. The plant connects to the Dominion Energy South Carolina balancing authority within the SERC NERC region.
The plant's battery energy storage system (BESS) has a capacity of 198 MWh, providing 3 hours of duration and utilizing lithium-ion battery chemistry (LIB). The solar array uses single-axis tracking. The latest annual generation data shows an output of 163,965 MWh, resulting in a capacity factor of 14.2%. Financial data is available for the plant, sourced from 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.
