Equinor's 100 MW Texas Battery Project Goes Online in ERCOT

Equinor's 100 MW Texas Battery Project Goes Online in ERCOT

Equinor’s 100-megawatt/200-megawatt-hour Citrus Flatts battery energy storage facility in Harlingen, Texas is now online, Rigzone reports, citing an Equinor press release.

Market Impact

Citrus Flatts is the second operational project from East Point Energy, Equinor’s grid-scale storage subsidiary. Combined with the 10-MW/20-MWh Sunset Ridge project that started service last year, the two facilities can supply enough electricity to power around 30,000 Texas homes for up to two hours within the ERCOT market, according to Equinor.

Both projects operate on a fully merchant basis in ERCOT, with Equinor’s trading arm, Danske Commodities, supporting asset management and portfolio optimization. “These projects represent a key step in building a competitive, scalable position in onshore power for Equinor,” the company said, adding that they mark East Point’s shift “from developer to independent power producer.” With Citrus Flatts online, Equinor has now commissioned five battery storage projects in four years. The company is also building four battery projects totaling 80 MW/160 MWh in the PJM market in Virginia, on track for commercial operation next year, and recently agreed to acquire a majority stake in the 1,483-MW Lackawanna Energy Center gas plant in Pennsylvania.

Equinor’s power segment generated $1.58 billion in H1 2026 revenue, up 43% year-on-year, though it posted an adjusted operating loss of $31 million, a 76% improvement from the same period last year. The company plans to direct 10% of its $11-13 billion annual capital budget for 2028-30 to its electricity business and aims to quadruple power generation to more than 20 terawatt hours by 2030.

What It Means for Subcontractors

• Electrical subs in South Texas should track ERCOT interconnection queues for follow-on battery storage projects, since East Point Energy has now completed two facilities in the region (Citrus Flatts at 100 MW/200 MWh in Harlingen and Sunset Ridge at 10 MW/20 MWh) and is expanding its merchant storage portfolio.
• Civil and site-prep contractors in the Rio Grande Valley area should note that Harlingen now has an operational grid-scale battery site, a marker for where transmission capacity and substation access already exist, useful data when bidding future storage or solar-plus-storage builds nearby.
• Firms with PJM market experience, particularly in Virginia and Pennsylvania, should watch for subcontract packages tied to Equinor’s four battery projects (80 MW/160 MWh combined) slated for commercial operation in 2027, as well as any upgrade work at the newly acquired 1,483-MW Lackawanna Energy Center gas plant.
• Companies serving Equinor’s Appalachian Basin gas operations, which deliver more than 1.7 billion cubic feet per day into the northeastern U.S., may see incremental work tied to the Lackawanna acquisition given its proximity to that gas position.
• Given Equinor’s stated plan to quadruple power generation to over 20 TWh by 2030 and commit 10% of its $11-13 billion annual 2028-30 capex to electricity, subcontractors in Texas and PJM territories should position now for repeat bid cycles as East Point Energy moves from single-project development to a broader buildout.
