Houston-based Fervo Energy collects $255M in additional funding

cha-ching

A Houston company that's responding to rising energy demand by harnessing geothermal energy through its technology has again secured millions in funding. The deal brings Fervo's total funding secured this year to around $600 million.

Fervo Energy announced that it has raised $255 million in new funding and capital availability. The $135 million corporate equity round was led by Capricorn’s Technology Impact Fund II with participating investors including Breakthrough Energy Ventures, CalSTRS, Congruent Ventures, CPP Investments, DCVC, Devon Energy, Galvanize Climate Solutions, Liberty Mutual Investments, Mercuria, and Sabanci Climate Ventures.

The funding will go toward supporting Fervo's ongoing and future geothermal projects.

“The demand for 24/7 carbon-free energy is at an all-time high, and Fervo is one of the only companies building large projects that will come online before the end of the decade,” Fervo CEO and Co-Founder Tim Latimer says in a news release. “Investors recognize that Fervo’s ability to get to scale quickly is vital in an evolving market that is seeing unprecedented energy demand from AI and other sources.”

Additionally, Fervo secured a $120 million letter of credit and term loan facility from Mercuria, an independent energy and commodity group that previously invested in the company.

“In surveying power markets across the U.S. today, the need for next-generation geothermal is undeniable,” Brian Falik, group chief investment officer of Mercuria, adds. “We believe in Fervo not just because their EGS approach is cost-effective, commercially viable, and already being deployed at scale, but because they set ambitious targets and consistently deliver.”

In February, Fervo secured $244 million in a financing round led by Devon Energy, and in September, the company received a $100 million bridge loan for the first phase of its ongoing project in Utah. This project, known as Project Cape, represents a 100x growth opportunity for Fervo, as Latimer explained to InnovationMap earlier this year. As of now, Project Cape is fully permitted up to 2 GW and will begin generating electricity in 2026, per the company.

Other wins for Fervo this year include moving into its new headquarters in downtown Houston, securing a power purchase agreement with California, growing its partnership with Google, and being named amongst the year's top inventions by Time magazine.

Texas developer closes $225M to supercharge US energy storage expansion

growth ahead

Austin-based developer and operator of utility-scale battery energy storage systems Jupiter Power has announced the successful closing of a $225 million corporate credit facility.

The transaction strengthens Jupiter Power’s U.S. portfolio, which includes one of the nation’s largest energy storage development pipelines, totaling over 12,000 megawatts. Jupiter Power, which also has offices in Houston, began commercial operations with the launch of its 400-megawatt-hour battery facility, Callisto I, in central Houston in August of 2024.

"Securing this corporate credit facility highlights the market's recognition of Jupiter Power as a leader in advancing large-scale energy storage solutions, as evidenced by our 2,575 megawatt hours of battery energy storage systems already in operation or construction," Jupiter Power CFO Jesse Campbell says in a news release. “This funding enhances our ability to advance projects across our pipeline in markets where energy storage is needed most. We greatly appreciate the support of our banking partners in this transaction.”

The $225 million in total revolving credit facilities will include up to $175 million in letters of credit and $50 million in revolving loans. Leading on the lender side includes Barclays Bank PLC, HSBC Bank USA, and Sumitomo Mitsui Banking Corp.

“HSBC is proud to support Jupiter Power with their credit facility as they continue to expand and accelerate the development of their energy storage projects across the United States,” Paul Snow, head of renewables - Americas at HSBC adds. “HSBC’s inaugural facility with Jupiter Power not only reinforces our commitment to financing premiere clean energy projects, but complements our ambition to deliver a net zero global economy.”

The Houston project is the first in the area, and Jupiter Power's ninth to deliver energy storage to ERCOT, which brings its total ERCOT fleet to 1,375-megawatt-hour capacity.

“It is an uncomfortable truth that highly pollutive energy sources are going to play an essential role in delivering an energy transition over the next several decades,” Charles Cherington, co-founder and managing partner of Ara, says in a news release. “We can ignore these staggering carbon emissions, or we can apply our proven methods and financing expertise to decarbonize the conventional energy value chain.”

The energy sector accounts for more than 75 percent of global greenhouse gas emissions.

“The world’s energy demands are increasing and complex, and renewable power needs time and support for it to fulfill rising global energy demand. Ara’s … skillset, portfolio network, and decarbonization management knowledge [are] perfectly positioned to attack the carbon-intensive energy sector,” Konar says.

Ara Partners closed its third private equity fund in December 2023 with over $2.8 billion in new commitments. As of June 30, 2024, Ara Partners had about $6.3 billion of assets under management.
