Cycles/day is discharged energy vs. usable capacity (~209 MWh). Capacity factor is avg discharge vs. peak.
Observed ERCOT settlement prices at BR_ARROW_ALL over 365 days (2025-10-13 to 2026-10-12).
The TB2 figure is a price benchmark, not revenue: it values one perfect-foresight cycle per day between the 2 cheapest and 2 dearest hours of each day, gross of round-trip losses, and excludes ancillary services and any physical dispatch constraint. It describes what this node’s price shape was worth over the window — it is not this asset’s realized capture, and no dispatch is assumed or modelled.
Portfolio membership follows the latest EIA-860 reporting entity. It does not imply ultimate ownership.
Bright Arrow Solar, LLC submitted a Chapter 313 tax-incentive application to Sulphur Springs Independent School District for a proposed 300 MWac solar facility in Hopkins County, developed by RWE Renewables Americas, LLC.
Bright Arrow Solar, LLC registered as a power-generation company with the Texas Public Utility Commission for a 300 MW solar unit and a 100 MW energy-storage unit, both interconnected through Oncor and operating within ERCOT.
RWE announced that the Bright Arrow battery-storage system came online in December 2023, with the 100 MWac/200 MWh BESS participating in the ERCOT market.
RWE issued a press release completing three U.S. battery-storage projects including Bright Arrow (100 MW/200 MWh), noting the solar photovoltaic output is provided to an NRG Energy affiliate and the BESS participates in ERCOT.
EIA-860 lists generator BASS, generator BASS1 with this operating date.
