Equinor Battery Storage Texas: Largest Project Goes Live
September 3, 2026 — Equinor has launched its largest battery installation in the United States. The Citrus Flatts energy storage facility has a capacity of 100 MW and 200 MWh. It is located near Dallas, Texas. This milestone is important for Equinor’s battery storage portfolio in Texas. It also impacts the rapidly evolving renewable energy storage landscape in the Electric Reliability Council of Texas (ERCOT).
Citrus Flatts – Texas’ New 100 MW Battery Storage Facility
The Citrus Flatts site sits on 12 acres of former agricultural land in Ellis County, about 35 miles south‑west of Dallas. It delivers 100 MW of power and 200 MWh of energy, enough to supply roughly 30,000 homes for two hours. The plant is owned and operated by East Point Energy, an Equinor‑backed developer whose East Point Energy battery project focuses on merchant‑type assets.
“This project will generate millions in tax revenue to support local priorities. As energy demand surges across Texas, it will strengthen the electrical grid and help keep energy costs affordable for families and businesses,” said Andrew Foukal, CEO of East Point Energy.
The facility started commercial operations on the same day. It joins a growing list of ERCOT battery storage facilities. These facilities help maintain grid stability. They do this during peak demand and when renewable generation spikes.
Building a Portfolio – From Sunset Ridge to Five Operational Batteries
Equinor’s U.S. storage push started in 2020 with Sunset Ridge battery storage, a 20 MW/40 MWh project in Texas that entered service in early 2022. Since then, the company has added four more installations, bringing the total to five operational batteries across four years. The portfolio now includes:
- Sunset Ridge battery storage – 20 MW/40 MWh (operational 2022)
- Midland Energy storage – 30 MW/60 MWh (operational 2023)
- Laredo Power hub – 25 MW/50 MWh (operational 2024)
- Citrus Flatts energy storage – 100 MW/200 MWh (operational 2026)
- West Texas Grid Assist – 15 MW/30 MWh (operational 2025)
Together, these assets provide ~190 MW of capacity and ~380 MWh of energy, reinforcing Equinor’s commitment to US battery storage projects 2024 and beyond.
Impact on the ERCOT Market
Citrus Flatts and the earlier Sunrise‑Ridge sites now deliver clean, dispatchable power that can smooth the infamous “duck curve” in ERCOT. Combined, they can power roughly 30,000 homes for two hours, equivalent to a small city’s nightly load.
The projects operate on a fully merchant basis, selling power and ancillary services directly into the market. Equinor partnered with Danske Commodities. They manage the trading portfolio together. They use sophisticated algorithms. These algorithms help capture value from price spikes, frequency regulation, and capacity markets.
Benefits of Battery Storage for Texas Grid Stability
- Energy security – Batteries store excess wind and solar, releasing it when generation falls.
- Grid reliability – Fast response times mitigate frequency deviations and prevent outages.
- Cost affordability – By deferring expensive generation upgrades, storage reduces overall electricity rates.
Texas remains the nation’s leader in oil, gas, wind, and emerging solar capacity. Adding Texas renewable energy storage helps the state meet its clean‑energy targets without compromising the reliability of its diverse generation mix.
Future Expansion – Projects in Virginia’s PJM Market
Equinor is not stopping at Texas. The company announced an 80 MW/160 MWh Virginia PJM battery portfolio slated for commissioning in 2027. This new suite will sit within the PJM Interconnection, targeting the East Coast’s growing need for fast‑acting storage to support grid‑forming renewables.
The Virginia rollout complements the Texas strategy, creating a bi‑regional footprint that showcases Equinor’s integrated power strategy across distinct market designs.
Conclusion – Equinor’s Integrated Power Strategy
The launch of Citrus Flatts underscores a strategic shift from pure oil and gas development to a balanced integrated power strategy. By owning, operating, and trading battery assets, Equinor captures value across the entire power value chain, from generation to market participation.
As the company expands its Virginia PJM battery portfolio and continues to enhance Texas renewable energy storage, it positions itself as a leading independent power producer (IPP) in both energy‑rich and policy‑driven markets.
