Houston energy co. secures $118.5M for battery energy storage project in south Texas

Tokyo Gas America has scored over $100 million in investment tax credits for project in Brazoria County that will supply power to Houstonians.

Houston-based Tokyo Gas America has received $118.5 million in investment tax credits for its battery energy storage system in Brazoria County. The system will supply power for the Houston-area territory served by the Electric Reliability Council of Texas (ERCOT).

San Francisco-based institutional fund sponsor Foss & Co. provided the tax equity for the Longbow BESS project, being developed by New York City-based Clean Capital Partners. Construction on the 174-megawatt battery energy storage system began earlier this year, and the project is expected to come online this summer.

“Longbow BESS represents a significant step forward in our commitment to providing clean and reliable energy solutions,” Ken Kiriishi, senior vice president of Tokyo Gas America, a wholly owned subsidiary of Tokyo Gas Co., says in a news release.

Earlier this year, Tokyo Gas America completed its $216 million purchase of Longbow BESS from Clean Capital Partners.

With the goal of owning and operating more than five gigawatts of renewable generation projects by 2030, Tokyo Gas America entered the U.S. renewables market in 2020 through its acquisition of the Aktina Solar Project. Tokyo Gas America bought the project from Chicago-based Hecate Energy, which develops, owns, and operates renewable energy projects in the U.S.

Aktina is the largest solar project in Texas, encompassing 1.4 million solar modules across 4,000 acres in Wharton County. The project, capable of generating as much as 500 megawatts of renewable energy, can power as many as 100,000 homes.

Aktina, which came online in 2021, supplies power to the ERCOT wholesale market. Construction of the roughly $3.2 million project recently wrapped up.

In February, Tokyo Gas America announced it had set up two subsidiaries to promote it gas marketing and trading operations in North America. As part of this venture, Tokyo Gas bought a 49 percent stake in ARM Energy Trading. Houston-based ARM Energy Holdings is the majority owner of ARM Energy Trading.

The accolades keep rolling in for Houston-based Fervo Energy, a producer of geothermal power.

Fervo lands at No. 6 on Time magazine and Statista’s new list of America’s Top GreenTech Companies of 2025. The ranking recognizes sustainability-focused companies based on factors such as impact, financial strength, and innovation.

Time notes that Fervo broke ground in 2023 in Utah on what the company claims will be the world’s largest geothermal plant. The plant is scheduled to start supplying carbon-free electricity to the grid next year and to reach its 400-megawatt capacity in three years.

“Technologies like this only make a difference if we deploy them at large-scale in a way that can reduce carbon emissions and increase the reliability of the grid,” Fervo CEO Tim Latimer told Time in 2023.

The startup was named North American Company of the Year by research and consulting firm Cleantech Group for 2025. Fervo topped the Global Cleantech 100, Cleantech Group’s annual list of the world’s most innovative and promising cleantech companies.

Last year, Fervo also made Time’s list of the 200 Best Inventions of 2024. Fervo was recognized in the green energy category for its FervoFlex geothermal power system.

Founded in 2017, Fervo is now a unicorn, meaning its valuation as a private company exceeds $1 billion. The startup’s valuation is estimated at $1.4 billion. According to PitchBook data, the company raised $634 million in the fourth quarter of 2024.

In all, eight Houston-area companies appear among the top 250 greentech companies ranked by Time and Statista. Other than Fervo, they are:

  • No. 43 Lancium Technologies, an energy storage and distribution company
  • No. 50 Solugen, a producer of sustainable chemicals.
  • No. 56 Quaise Energy, which specializes in terawatt-scale geothermal power.
  • No. 129 Plus Power, a developer, owner and operator of battery storage projects.
  • No. 218 Dream Harvest, which promotes sustainable vertical farming.
  • No. 225 Cemvita, which uses synthetic biology to convert carbon emissions into bio-based chemicals.
  • No. 226 Syzygy Plasmonics, which decarbonizes chemical production.
Vermont-based BETA Technologies claimed the No. 1 spot. The company manufactures electric aircraft.
