Roadrunner, LLC
Enel Green PowerUpton County
Roadrunner is a solar-and-battery hybrid in Upton County, Texas. EIA's May 2026 inventory reports two photovoltaic generators totaling 400 MW AC and 497 MW DC plus a 63.3 MW / 108.6 MWh battery; operating net summer capability is 450 MW. Enel describes the solar project as 497 MW across a 252 MW first phase and 245 MW second phase, with 1.2 million bifacial panels, and describes the storage project as 57 MW / 85.7 MWh. The EIA and Enel figures use different AC, DC, seasonal, and developer scopes and are not interchangeable.

Cycles/day is discharged energy vs. usable capacity (~81 MWh). Capacity factor is avg discharge vs. peak.
Observed ERCOT settlement prices at QUEEN_BA_RN over 365 days (2025-10-27 to 2026-10-26).
The TB1 figure is a price benchmark, not revenue: it values one perfect-foresight cycle per day between the cheapest and dearest hour 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.
