The Houston area will soon be home to what's being lauded as the first fully sustainable 1-gigawatt data center on a 600-acres site east of Houston.

Data center-as-a-service company ECL, headquartered in Mountain View, California, announced its plans to build the ECL TerraSite-TX1. Hardware and cloud service company Lambda will serve as its first tenant. Lambda and other AI leaders will get access to necessary space and power for the next wave zero emission innovations.

Phase 1 of TerraSite-TX1 will be complete by summer of 2025 with a cost of approximately $450 million. The 50 megawatt of data center capacity will be utilized by data center cloud and AI cloud operators. The 1-gigawatt site will be constructed at a cost of approximately $8 billion. The funding will come from ECL and financial partners.

ECL Terrasite-TX1 comes at a needed time for Texas with The Electric Reliability Council of Texas stating on June 12 that the state’s power grid needs will grow approximately double by 2030. This is due in part to the growth of data centers and AI. The ECL Terrasite-TX1 is built to help eliminate the stress on the state’s power grid and help facilitate “state-level economic development and growth of the AI industry,” according to a news release.

ECL data centers are built to be modular, which allows for expansion in 1-megawatt increments. They are “ built to suit” and delivered in less than 12 months, which is shorter than the industry standard of 36 to 48.

“While others talk about delivering off-grid, hydrogen-powered data centers in five, ten, or 20 years, only ECL is giving the AI industry the space, power, and peace of mind they and their customers need, now,” Yuval Bachar, co-founder and CEO of ECL, says in a news release. “The level of innovation that we have introduced to the market is unprecedented and will serve not only us and our customers but the entire data center industry for decades to come.”

ECL’s ECL-MV1 is the world’s first off-grid, hydrogen-powered modular data center that operates 24/7 with zero emissions, less noise, and a negative water footprint that replenishes water to the community. ECL-MV1 offers a 10x increase in “energy efficiency with a power usage effectiveness of 1.05 and a 7-times improvement in data density per rack, which is ideal for AI high-density demand” according to the release.

“The data center technology committed to by ECL is truly transformative in the industry,” Lambda's Vice President for Data Center Infrastructure Ken Patchett adds. “We believe ECL’s technology could unlock a powerful and eco-conscious foundation for AI advancement. This new infrastructure could give researchers and developers essential computational resources while drastically reducing the environmental impact of AI operations.”

Solar manufacturer expands Houston footprint with new 4 GW factory

coming soon

Houston-based SEG Solar plans to open a new 4-gigawatt solar module manufacturing facility in Cypress.

The facility represents more than a $200 million investment and will raise SEG's total annual U.S. module production capacity to approximately 6 gigawatts, according to a new release. The expansion is part of SEG’s long-term goal of becoming one of the largest 100 percent U.S.-owned module manufacturers.

The new 500,000-square-foot facility will be located on Telge Road and is expected to create 800 new jobs, according to reports.

“This new facility marks an important milestone for SEG,” Timothy Johnson, VP of operations, said in the release. “It will further strengthen our U.S. manufacturing capabilities while supporting ongoing technology innovation. The plant is designed with the flexibility to integrate next-generation technologies, including (heterojunction solar technology) as the industry evolves.”

Commercial operations at the new facility are expected to commence in Q3 2026.

SEG is also developing a 5-gigawatt ingot and wafer manufacturing facility in Indonesia. Construction on the facility is expected to begin in Q2 2026.

In 2024, SEG Solar opened a new $60 million, 250,000-square-foot facility in Houston to house its production workshops, raw material warehouses, administrative offices, finished goods warehouses and supporting infrastructure. Read more here.

Fervo Energy bumps up IPO target to $1.82B

IPO update

Houston-based geothermal power company Fervo Energy is now eyeing an IPO that would raise $1.75 billion to $1.82 billion, up from the previous target of $1.33 billion.

In paperwork filed Monday, May 11 with the U.S. Securities and Exchange Commission, Fervo says it plans to sell 70 million shares of Class A common stock at $25 to $26 per share.

In addition, Fervo expects to grant underwriters 30-day options to buy up to 8.33 million additional shares of Class A common stock. This could raise nearly $200 million.

When it announced the IPO on May 4, Fervo aimed to sell 55.56 million shares at $21 to $24 per share, which would have raised $1.17 billion to $1.33 billion. The initial valuation target was $6.5 billion.

A date for the IPO hasn’t been scheduled. Fervo’s stock will be listed on Nasdaq under the ticker symbol FRVO.

Fervo, founded in 2017, has attracted about $1.5 billion in funding from investors such as Bill Gates-founded Breakthrough Energy Ventures, Google, Mitsubishi Heavy Industries, Devon Energy (which is moving its headquarters to Houston), Tesla co-founder JB Straubel, CalSTRS, Liberty Mutual Investments, AllianceBernstein, JPMorgan, Bank of America and Sumitomo Mitsui Trust Bank.

Fervo’s marquee project is Cape Station in Beaver County, Utah, the world’s largest EGS (enhanced geothermal system) project. The first phase will deliver 100 megawatts of baseload clean power, with the second phase adding another 400 megawatts. The site can accommodate 2 gigawatts of geothermal energy. Fervo holds more than 595,000 leased acres for potential expansion.

Cape Station has secured power purchase agreements for the entire 500-megawatt capacity. Customers include Houston-based Shell Energy North America and Southern California Edison.

Modular nuclear reactor company opens office in Houston

new to hou

The nuclear energy renaissance continues in Texas with an announcement by NuScale Power. The Oregon-based provider of proprietary and innovative advanced small modular reactor (SMR) nuclear technology announced in April it would be opening office space in Houston’s CityCentre.

“Opening this space in Houston underscores our commitment to meeting rising energy demand with safe, scalable nuclear technology,” John Hopkins, NuScale president and CEO, said in a news release. “This move expands our presence in a key market for partners, prospective customers, and stakeholders in addition to positioning us for the future as we focus on the near-term deployment of our industry-leading technology. Texas is leading the way in embracing advanced nuclear for grid resilience and industrial decarbonization, and we’re proud to expand our footprint and capabilities in this important region.”

Interest in nuclear power has been growing in recent years thanks to tensions with oil-rich nations, concerns about man-made climate change from fossil fuels, and the rapidly increasing power needs of data centers. Both Dow and Texas A&M University have announced expanded nuclear power projects in the last year, with an eye of changing the face of Texas’s energy industry through smaller, safer fission reactors.

Enter NuScale, founded in 2007 from technology developed at the University of Oregon. Their modular SMR technology generates 77 megawatts and is one of the only small modular reactors (SMR) to receive design approval from the U.S. Nuclear Regulatory Commission (NRC). These advances have led to runaway success for NuScale, whose stock has risen by more than 1,670 percent since the start of 2024.

The new operations campus in CityCentre is expected to facilitate the movement, installation and coordination of NuScale technology into the various energy systems. Typically, SMRs are used for off-grid installations, desalination operations, mining facilities and similar areas that lack infrastructure. However, the modularity means that they can be easily deployed to a variety of areas.

It comes none too soon. ERCOT projects that Texas data centers alone will require 77,965 megawatts by 2030.
