Equinor brings 100 MW/200 MWh Citrus Flatts online
Estimated reading time: 4 minutes · Last updated:
Equinor’s East Point Energy has started commercial operation at Citrus Flatts, a 100 MW/200 MWh energy storage facility in Harlingen, Texas. The site joins East Point’s 10 MW/20 MWh Sunset Ridge and, together, the two assets can supply enough electricity to power around 30,000 homes for up to two hours inside ERCOT. Equinor says Citrus Flatts is part of a push from developer to independent power producer (IPP), and the battery will run on a fully merchant basis in ERCOT supported by trading and optimisation work with Danske Commodities. The primary technical function is threefold: time-shift surplus generation, provide grid flexibility at peaks, and support local reliability.
The start-up of these facilities underscores Equinor’s ambition to grow its integrated power business, delivering flexible and reliable energy solutions in attractive power markets,

Key takeaways
- East Point Energy, owned by Equinor, has started commercial operations at Citrus Flatts, a 100 MW/200 MWh energy storage facility in Harlingen, Texas.
- Equinor has brought five battery storage facilities into commercial production in four years; Citrus Flatts is East Point’s second operational project after the 10 MW/20 MWh Sunset Ridge deployment last year.
- Citrus Flatts and Sunset Ridge together can supply enough electricity to power around 30,000 homes for up to two hours within the ERCOT market.

What Citrus Flatts adds to Equinor’s US portfolio
Citrus Flatts is a 100 MW/200 MWh battery installation operated by East Point Energy, a wholly owned Equinor company. The project is presented as East Point’s move from developer to independent power producer, a strategic shift that keeps assets under Equinor’s commercial control rather than selling them immediately after construction. That change matters because East Point will run Citrus Flatts on a fully merchant basis inside ERCOT, exposing the plant to real‑time and ancillary markets rather than to long‑term contracted revenue.
The announcement links operational performance to Equinor’s trading capabilities: Danske Commodities will work on asset management and portfolio optimisation. The company frames this as an integrated, portfolio‑driven approach that aims to maximise value across power markets. The key technical capacity is the plant’s 200 MWh energy reservoir, which enables multi‑hour discharge for peak events and system support.
How the two Texas sites work in ERCOT and local impacts
Combined with Sunset Ridge, Citrus Flatts increases East Point’s operating capacity to a level Equinor says can address short-duration peaks: the two facilities together provide enough energy to power around 30,000 homes for up to two hours in the ERCOT market. Operationally, that means charging when wind or solar generation is high or prices are low, and discharging at times of peak demand or during scarcity events to capture merchant value.
The company highlighted local economic benefits in its statement. Andrew Foukal, CEO of East Point Energy, said, "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." That tax‑revenue claim is in the announcement; Equinor did not provide a specific dollar figure in the release.
Virginia portfolio and the next operational milestones
Beyond Texas, Equinor says construction is underway on a Virginia portfolio intended for PJM: four projects totalling 80 MW/160 MWh. The announcement states those projects are on track to reach commercial operation in early 2027. If delivered, the Virginia batch will extend East Point’s merchant‑market footprint from ERCOT into PJM, where pricing drivers and ancillary service opportunities differ.
The Virginia projects are presented as a near‑term scale‑up: smaller unit sizes aggregated across the region and managed alongside Equinor’s trading desk. Early 2027 is the company’s target for commercial operation; the statement does not include detailed commissioning schedules, interconnection milestones or revenue projections for the PJM assets.
| Project | Location | Power (MW) | Energy (MWh) | Status |
|---|---|---|---|---|
| Citrus Flatts | Harlingen, Cameron County, Texas | 100 | 200 | Commercial operation started |
| Sunset Ridge | Texas | 10 | 20 | Operational (started last year) |
| Virginia portfolio (4 projects) | Virginia (PJM) | 80 | 160 | Under construction; on track early 2027 |
Case for and against the merchant storage push
The case for
- Equinor’s use of Danske Commodities for asset management could raise merchant revenues by optimising charge/discharge across markets and short‑term products.
- Scaling from development to IPP keeps operational upside inside Equinor, allowing the company to capture price spikes and ancillary service payments rather than selling projects outright.
The case against
- Operating on a fully merchant basis exposes these assets to ERCOT price volatility and extreme-event risk, where revenue can be concentrated in short windows.
- Delivery and interconnection risks for the Virginia projects could delay commercial operation or add costs; the announcement gives an early‑2027 target but no detailed timetable.
What to be careful about
- Merchant revenue volatility in ERCOT could reduce expected income if scarcity events are fewer or prices compress.
- Construction or interconnection delays in Virginia would push back the early‑2027 commercial target and compress near‑term returns.
- Reliance on trading optimisation concentrates value in Equinor’s commercial processes; underperformance in optimisation would lower project economics.
The bottom line
Citrus Flatts is Equinor’s latest step in scaling merchant battery operations in the US, adding a 100 MW/200 MWh installation to an existing 10 MW/20 MWh asset. The move reflects a deliberate transition from project development to an IPP model that relies on trading and optimisation to extract value. The company’s stated next milestone is a four‑project, 80 MW/160 MWh portfolio in Virginia scheduled for early 2027; how those assets perform in PJM and how merchant revenues develop in ERCOT will determine whether the approach delivers the value Equinor forecasts.
What to watch
- Watch for the four Virginia projects totalling 80 MW/160 MWh to reach commercial operation in early 2027.
- Watch for Equinor or East Point Energy updates on merchant performance, optimisation outcomes with Danske Commodities, and any detailed tax‑revenue figures; no date has been set.
