Estonian Solar Project
Enel Green Power Estonian Solar Project, LLCDelta County
Estonian Solar Project, LLC is a utility-scale solar-plus-storage hybrid facility located in Delta County, Texas, within the ERCOT balancing area. The project comprises a 204.5 MW solar photovoltaic generation unit with single-axis tracking and bifacial modules, paired with a 100 MW lithium-ion battery energy storage system, for 304.5 MW combined nameplate capacity. Enel North America, through its renewable-energy subsidiary Enel Green Power North America, developed, built, and operates the facility. The facility began operations in February 2025 with staggered unit commissioning. The project is supported by power purchase agreements with BXP, Inc. for 21 MW and with Capri Holdings Limited. Expected annual generation is approximately 499 GWh.

Cycles/day is discharged energy vs. usable capacity (~168 MWh). Capacity factor is avg discharge vs. peak.
Observed ERCOT settlement prices at ESTONIAN_ALL over 365 days (2025-10-12 to 2026-10-11).
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.
