US Battery Storage Boom Accelerates as Grid Adds About 52 GW of Capacity, EIA Says

By

The US power sector is rapidly expanding its battery storage fleet as utilities and independent power producers turn to large-scale batteries to balance rising renewable energy generation and capture higher electricity prices, Energy Information Administration strategists said in a note Sunday.

The EIA analysts said battery storage capacity in the US grew at an average annual rate of 70% over the past three years, reaching 43.6 gigawatts of operational capacity by the end of 2025.

The growth continued into 2026, with operators adding 8.3 GW of battery storage capacity in the first six months of the year, bringing total installed nameplate capacity to about 52 GW.

The EIA said that developers are expected to add another 54 GW of battery storage capacity over the next two and a half years. Planned additions include 14 GW in H2 2026, 26 GW in 2027 and a further 14 GW in 2028, the agency said.

Battery storage paired with solar projects is emerging as a key driver of the expansion. Solar-plus-storage facilities allow power producers to store electricity when wholesale prices are low and release it during periods of higher demand, improving project economics while helping grid operators manage fluctuations in renewable generation.

The EIA said that the largest battery storage projects in the US are increasingly being built alongside photovoltaic facilities.

The Bellefield Solar and Energy Storage Farm in California, which began operations in December 2025, combines 500 megawatts of solar generation with 500 MW of battery storage capacity serving the California Independent System Operator market.

The project's developers plan to double both solar and storage capacity, with the additional capacity expected to come online by November 2026. The EIA said that if completed, the expanded facility would become the largest battery storage project in the US.

Florida's Manatee Solar Energy Center, operated since 2021, currently ranks among the country's largest storage installations, with 409 MW of battery capacity paired with 75 MW of solar generation.

Nevada's Gemini Solar Hybrid project, which began operations in 2024, combines 690 MW of photovoltaic capacity with 380 MW of battery storage, underscoring the growing trend of integrating large-scale batteries directly with renewable power plants.

The surge in battery installations comes as utilities and independent power producers look to address the challenges posed by intermittent renewable generation. Storage systems can help smooth fluctuations in solar output, provide electricity during peak demand periods and reduce reliance on more expensive generation sources.

US Natural Gas Update: Futures Fall on Larger-than-Expected Inventory Build

US natural gas futures fell on Thursday, with front-month prices dropping to their lowest level in more than three months after government data showed a larger-than-expected increase in storage, reinforcing the perception of an amply supplied market.The front-month Henry Hub contract and the continuous contract both fell 2.05% to settle at $2.633 per million British thermal units.The US Energy Information Administration reported that working gas in storage increased by 33 billion cubic feet in the week ended July 31. The build exceeded market expectations for a 30 Bcf injection and was well above the five-year average increase of 23 Bcf for the period, underscoring a comfortable supply backdrop.But losses were tempered by forecasts calling for warmer near-term weather across key US demand regions, which could lift natural gas consumption from power generators as air-conditioning use increases. Commodity Weather Group said forecast models shifted warmer on Thursday, with above-average temperatures expected across the Northeast and western US through Aug. 10.Total lower-48 gas consumption was estimated at 83.2 Bcf/d on Thursday, up 7.5% from a year earlier. Celsius Energy said powerburn on Aug. 4 hit 45.8 Bcf, a 2.2 Bcf rise over the same day last year.The market is also looking ahead to additional supply growth next month. Energy Transfer's Hugh Brinson Pipeline is expected to reach its full 1.5 Bcf/d capacity by Sept. 1, increasing the flow of Permian Basin natural gas to the Henry Hub pricing point in Erath, Louisiana.Current production remains robust. Lower-48 dry gas output was estimated at 111.2 Bcf/d on Thursday, up 1.8% from a year earlier, Barchart, citing BNEF data, said. Separately, Trading Economics said Lower-48 production averaged a record 110.7 Bcf/d in July.Meanwhile, net feedgas flows to US LNG export terminals were estimated at 18.5 Bcf/d on Thursday, remaining below full capacity because of scheduled maintenance at liquefaction facilities on the US Gulf Coast. However, LNG feedgas volumes were up 3.3% from the previous week.

Northern Oil and Gas Reports Record Q2 Natural Gas Production, Maintains 2026 Output Outlook

Northern Oil and Gas (NOG) reported Q2 earnings Thursday, showing total production of 145,659 barrels of oil equivalent per day, up from 134,094 boe/d a year earlier.Total net production increased to 13.256 million boe for the quarter ended June 30, up from 12.203 million boe a year earlier.Oil production totaled 6.213 million barrels for the quarter, down from 7.002 million barrels a year earlier, while average daily oil production declined to 68,275 barrels per day from 76,944 b/d.Natural gas production increased to a record 42.254 billion cubic feet in the quarter from 31.204 Bcf a year earlier, while average daily production climbed to 464.3 million cubic feet per day, up from 342.9 MMcf/d in the year-ago quarter.Oil volumes reflected about 7,000 boe/d of temporary well shut-ins and three deferred turn-in lines in certain Permian assets, NOG said.The company added 12.7 net wells to production during the quarter, compared with 13.5 net wells a year earlier, excluding major acquisitions.Appalachian production reached a record during the quarter as the West Virginia joint development program concluded and the Utica joint development contributed a full quarter of production.NOG completed its Duvernay Light Oil joint development on June 1 for total consideration of $262.1 million and closed 30 ground game transactions that added more than 2,300 net acres and 6.2 net wells for $44.7 million, including associated development costs.Northern Oil and Gas maintained its full-year 2026 production guidance at 143,000 boe/d to 148,000 boe/d and annual oil production guidance at 71,500 b/d to 73,500 b/d.The company also reaffirmed total budgeted capital expenditures of $850 million to $900 million and expects to turn 74 to 76 net wells in line this year.

US Reportedly Weighs Delay to New Solar Import Tariffs as Industry Braces for Higher Costs

The US is considering delaying the collection of planned tariffs on imported solar products made with polysilicon by up to four months, a move that could trigger a surge in imports before the duties take effect, multiple news outlets reported on Thursday.US officials are reportedly weighing a 90- to 120-day phase-in period for the tariffs, which US President Donald Trump could announce as early as Thursday. The proposal remains under discussion and could change.The new measures would impose minimum import prices and tariffs of at least 15% on polysilicon, as well as solar wafers, cells and panels made from the material. Polysilicon is a key ingredient in most solar panels.A temporary delay would give renewable energy developers an opportunity to import lower-cost equipment before the tariffs raise prices. However, US manufacturers argue that postponing the levies would allow a wave of cheap imports to enter the market, undermining the administration's efforts to rebuild domestic production.The proposed tariffs are part of a broader strategy to expand US production of polysilicon and other solar manufacturing components after China became the world's dominant supplier over the past decade. The administration is also expected to introduce incentives aimed at encouraging companies to build or expand factories in the US.The White House did not immediately respond to a request for comment from.
