A new battery energy storage facility in Houston is officially up and running to power the ERCOT grid with a supply of reliable, zero emissions power.

Jupiter Power announced the commercial operations launch of its 400-megawatt-hour battery facility, Callisto I, in central Houston on the site of the former HL&P H.O. Clarke fossil fuel power plant.

"Jupiter couldn't be prouder about bringing the Callisto I project online," Andy Bowman, CEO of Jupiter Power, says in a news release. "This project responds to lawmakers' calls to increase affordable and dispatchable new generation in an area where people need more power. Callisto I is the first energy storage project at this scale in the City of Houston and will help meet Houston's growing power needs while also increasing resiliency from extreme weather events."

The new project is Jupiter Power's ninth project to deliver energy storage to ERCOT — bringing its total ERCOT fleet to 1,375-megawatt-hour capacity — but its the first in the Houston area. The company is currently developing over 11,000 megawatts of projects across the country. Founded in 2017, Jupiter Power is headquartered in Austin and has offices in Houston and Chicago.

"The announcement of Jupiter Power's Callisto I Energy Storage project is significant and exciting for the region, as it's the first large-scale transmission-connected energy storage project in the City of Houston," Jane Stricker, senior vice president at the Greater Houston Partnership and executive director at the Houston Energy Transition Initiative, adds. "This critical project will help address peak power demand and is another great example of our region's leadership in scaling and deploying impactful solutions for an all the above energy future."

Among the company's financial backers is Houston-based EnCap Energy Transition, which invested in Jupiter Power via its Fund II.

Houston firm's portfolio co. goes online with solar, energy storage facility in Nevada

powering on

A portfolio company of Quinbrook Infrastructure Partners, an energy-focused investment manager with U.S. offices in Houston and New York, has flipped the switch on its solar power and battery energy storage system in Nevada’s Mojave Desert.

The portfolio company, Oakland, California-based Primergy Solar, says its Gemini Solar + Storage project near Las Vegas is now fully operational.

Gemini’s 1.8 million solar panels can generate up to 690 megawatts of power, enough to meet 10 percent of Nevada’s peak power demand. The panels are paired with 380 megawatts of four-hour battery storage.

“Gemini creates a blueprint for holistic and innovative clean energy development at mega scale, and we are proud to have brought this milestone project to life and to have delivered so many positive impacts across job creation, environmental stewardship, and local community engagement,” David Scaysbrook, co-founder and managing partner of Quinbrook, says in a news release.

Primergy says Gemini is the biggest solar-and-storage duo in the U.S.

“Achieving full commercial operations marks a significant technical and financial milestone for our team. We successfully navigated challenging supply chain and inflation issues through proactive planning and collaboration to bring this project online,” Primergy CEO Ty Daul says.

Primergy develops, owns, and operates utility-scale solar power and battery storage projects across the U.S. It manages projects in several U.S. energy markets, including the one served by the Electric Reliability Council of Texas (ERCOT).

As Gemini was taking shape, Primergy and Quinbrook closed on $1.9 billion in debt and tax equity financing for construction and development.

In October 2022, APG, the largest pension asset manager in the Netherlands, acquired a 49 percent ownership stake in Gemini on behalf of pension fund client ABP.

In April 2024, the remaining 51 percent share of the project was acquired by the $600 million Quinbrook Valley of Fire Fund. Funds associated with Blackstone Strategic Partners and Ares Management Infrastructure Secondaries were the lead investors.

power move

Houston-based clean energy company Intersect Power has wrapped up $837 million in financing for the construction and operation of three standalone battery energy storage systems in Texas.

The money came in the form of debt financing, construction debt, and tax equity. The projects qualify for tax credits under the federal Inflation Reduction Act. Backers of the financing include Deutsche Bank, Morgan Stanley, and affiliates of HPS Investment Partners.

All three storage systems — Lumina I, Lumina II, and Radian — are expected to be online this year. Each system will be capable of storing 320 megawatts of solar power with a two-hour duration.

“Batteries will be a vital part of the energy transition and are the perfect complement to the billions of dollars of solar generation that we are building in California and Texas,” Sheldon Kimber, founder and CEO of Intersect, says in a news release.

Kimber says the storage systems will help Intersect Power triple the size of its portfolio over the next three years.

Intersect’s portfolio features 2.2 gigawatts of solar projects that are already operating, and 2.4 gigawatt hours of storage being operated or built. The company was founded in 2016.

Intersect recently signed a deal with Tesla Energy for 15.2 gigawatt hours of Megapack battery energy storage systems. The contract, which will deliver systems for Intersect projects in Texas and California, ends in 2030.

Houston energy transition growth capital firm closes $1.5B fund

A Houston-based energy transition-focused growth capital firm announced the close of its second fund to the tune of $1.5 billion.

EnCap Energy Transition's Fund II, or EETF II, was created to invest in solutions to decarbonize the power industry, and invest in low carbon fuels and carbon management.This second energy transition fund follows EnCap Energy Transition Fund I, a $1.2 billion fund that deployed capital to seven material portfolio company investments and four fund realizations with Broad Reach Power, Jupiter Power, Triple Oak, and Paloma Solar & Wind.

Previously, the company made investment commitments to five portfolio companies through EETF II, including Bildmore Renewables, Linea Energy, Parliament Solar, Power Transitions, and Arbor Renewable Gas. With the Bildmore arm, the EnCap fund aims to fuel development of renewable energy projects that can’t attract traditional tax equity financing.

EnCap expects to have 8-10 portfolio companies in EETF II in total.

"The EnCap Energy Transition team is proud to have raised a sizeable pool of capital to continue to invest in the opportunity created by the shift to a lower-carbon energy system,” EnCap Energy Transition Managing Partner Jim Hughes says in a news release.

“We greatly appreciate the strong support from our existing investor base and are pleased to have added a number of new, high-quality investors, both domestically and internationally," he continues. "Since our inception in 2019, we now manage approximately $2.7 billion of capital commitments to invest in decarbonization and are excited for the opportunities ahead of us."

Recently,EnCap was part of a deal in the battery energy storage business carrying an equity value of more than $1 billion. Engie purchased the majority of a startup . Broad Reach’s battery storage business from EnCap Energy Transition Fund I. Broad Reach launched in 2019 with backing from EnCap.

“We continue to believe all sources of energy are needed to support the world’s growing energy needs and that our Energy Transition Team will build off the significant success achieved to date,” said EnCap Managing Partner Jason DeLorenzo in a news release.

French company to acquire Houston-based battery storage startup in $1B deal

M&A Moves

A French utility company is buying the bulk of Houston-based Broad Reach Power’s battery energy storage business in a deal carrying an equity value of more than $1 billion.

Engie, has agreed to purchase the majority of the startup’s battery storage business from EnCap Energy Transition Fund I and three investment partners — New York City-based Yorktown Partners, Switzerland-based Mercuria Energy, and New York City-based Apollo Infrastructure Funds.

“This acquisition is fully in line with Engie’s strategy: It will contribute to the development of a low-carbon, affordable, and resilient energy system where flexible assets will play a critical role alongside renewables,” says Catherine MacGregor, the utility’s CEO.

Broad Reach launched in 2019 with backing from EnCap Energy Transition, an arm of Houston-based private equity firm EnCap Investments. Apollo Global Management, an asset manager that controls Apollo Infrastructure Funds, bought a 50 percent stake in Broad Reach in 2021.

The deal includes 350 megawatts of grid-scale battery assets that already are operating and 880 megawatts of assets under construction, primarily in the territory served by the Electric Reliability Council of Texas (ERCOT). It also includes a 1.7-gigawatt pipeline of battery storage projects that are in the advanced stage of development and a significant pipeline of early-stage projects.

In July, Broad Reach said it had lined up $435 million in credit facilities to support the 880 megawatts’ worth of systems under construction in Texas and California.

The Broad Reach acquisition does not include the company’s 1.8-gigawatt portfolio of solar and wind power projects, or its four gigawatt-hours’ worth of battery storage in the Mountain West.

The deal is expected to close in the fourth quarter of this year. The purchase price wasn’t disclosed, but the Bloomberg news service reports the deal will cause Engie to “take a $1.6 billion hit” to it net debt.

Shawn Cumberland, managing partner of EnCap and chairman of Broad Reach, calls Broad Reach “the top battery storage player in the U.S. market.” And Corinne Still, an infrastructure partner at Apollo, refers to Broad Reach as “the leading and most innovative” battery energy storage operator in North America.

“It has been a terrific honor and pleasure to be part of the rapid growth of the U.S. energy storage sector from the very beginning and see our company grow into one of the top developers,” says Doug Moorehead, founder and COO of Broad Reach.

Japanese agency invests $36M into Houston e-fuels company's portfolio

coming in hot

Houston-based electrofuel company HIF Global has secured a $36 million investment from the Japan Organization for Metals and Energy Security, a government agency.

The investment, made through an e-fuel subsidiary of Japanese energy company Idemitsu Kosan, is earmarked for HIF’s e-fuel projects in the U.S., Australia, Chile, and Uruguay.

Earlier this year, Idemitsu led a $164 million investment round in HIF. Of that amount, Idemitsu chipped in $114 million. Other investors included Houston-based Baker Hughes along with AME, EIG, Gemstone Investments, and Porsche.

In total, HIF has raised $200 million this year.

“Japan set a priority for the commercial introduction of e-fuels into its fuel supply to support their mandate for 46 percent [greenhouse gas] emissions reduction by 2030. We have already proven e-fuels are a real solution with over 18 months of e-fuels production from our Haru Oni facility in southern Chile,” says Cesar Norton, president and CEO of HIF.

In 2023, Idemitsu agreed to buy e-methanol from HIF’s $6 billion plant in Matagorda County. HIF says the plant will be the world’s first large-scale e-fuel facility. The plant is expected to produce about 1.4 million metric tons per year of e-methanol and about 300,000 metric tons of green hydrogen per year by 2027.

HIF, founded in 2016, aims to produce 150,000 barrels per day of e-fuel and recycle 25 million metric tons per year of carbon dioxide by 2035. E-fuels, which are synthetic alternatives to fossil fuels, include e-gasoline, e-diesel, and e-sustainable aviation fuel converted from e-methanol.

Using electrolyzers powered by renewable energy, HIF begins the e-fuel process by separating hydrogen from oxygen in water. The company then couples the resulting green hydrogen with recycled carbon dioxide to create carbon-neutral e-fuels.

California geothermal co. grows C-suite, grows presence in Houston

making moves

A geothermal company with its headquarters in Palo Alto, California, has named new members of its C-suite and, at the same time, has expanded its operational footprint in Houston.

XGS Energy promoted Axel-Pierre Bois to CTO and Lucy Darago to chief commercial officer. Darago is based in Austin, and Bois, from France, lists his role as based in Houston on LinkedIn. Both have worked at XGS since February of last year.

“Axel and Lucy’s proven operational excellence and technical knowledge has helped propel XGS forward as we enter our next phase of growth,” Josh Prueher, CEO of XGS Energy, says in a news release. “I’m thrilled to have them both join XGS’ C-suite and have their support as we continue to grow our team, further advance our next-generation geothermal technology, and invest in our multi-gigawatt project pipeline.”

The news coincides with XGS's recent lease of over 10,000 square feet of office space in Memorial City. The company reports it plans to continue growth in the Houston region, "leveraging the region’s leading engineering and operational workforce and intensifying energy transition activity," reads the statement.

Bois was promoted from senior vice president of technology and has over 30 years of experience in geomechanics, wellbore integrity, completions design, and cement and rock testing. He previously founded and served as CEO of CURISTEC, a technical advisory firm providing services in oil and gas, geothermal, and geologic storage industries.

“We have developed a unique and proprietary approach to boosting the heat-harvesting potential of geothermal wells that is ready for commercial deployment in a range of environments today. I am excited to continue to grow our incredible team of scientists and engineers working on this important technology,” Bois says in the release. “We’re at the beginning of what this technology can unlock when it comes to supplying reliable, clean, and affordable geothermal energy globally.”

In her previous role as vice president of strategy, Darago led XGS’s financing strategy, which included a $20 million Series A expansion announced earlier this year. As CCO, she will oversee XGS’ global project development and will maintain a leading role in corporate affairs.

“It’s an exciting time to bring XGS’ technology to market. Demand for carbon-free baseload energy is at a record high, and the XGS system’s ability to unlock geothermal in more places, in a predictable and bankable way, is tailor-made for this moment,” Darago adds. “I am honored by our team and Board’s trust and look forward to helping drive the next stage of growth for XGS.”
