Clean energy and transmission infrastructure company Pattern Energy completed the acquisition of Canadian independent power producer Cordelio Power this month.

Pattern Energy, which is headquartered in San Francisco and has major operations in Houston, will now own one of the largest independent clean energy infrastructure platforms in North America, according to a release.

Pattern Energy will add approximately 1,550 megawatts of operating and in-construction assets, including 16 wind, solar and energy storage projects across the United States and Canada, as part of the deal. In addition, they have also acquired the majority of Cordelio’s development pipeline in key U.S. markets and members of Cordelio’s team.

“Closing this transaction marks a significant milestone for Pattern Energy as we continue to scale our platform to meet North America’s growing energy needs,” Hunter Armistead, CEO of Pattern Energy, said in the release. “Cordelio brings a highly complementary portfolio of quality assets and a talented team. Together, we are even better positioned to power the future.”

Currently, Pattern Energy’s portfolio includes wind, solar and energy storage projects in over 40 facilities in North America. Pattern Energy had 12,000 megawatts of operating and in-construction capacity before the deal.

The acquisition was first announced Jan. 6, 2025.

“Pattern and Cordelio share a commitment to responsible development and the communities in which we work,” Chris Hind, CEO of Cordelio Power, said in a news release. “We look forward to joining with Pattern Energy to deliver high-quality projects with expanded product offerings to support customers across more markets.”

Pattern Energy doubled down on its Houston commercial space in 2023, moving the company's development, meteorological, transmission and energy trading teams to a new office in the Montrose Collective. The company's Operations Control Center is also based in Houston.

Its Houston-based development team was assigned to work on Pattern's SunZia Transmission and Wind project in New Mexico and Arizona, expected to be one of the largest clean energy infrastructure projects in U.S. The project is targeting commercial operations this year, according to Pattern Energy's website.

Panel: Houston's access to talent, strong network drives it as a city for scaling energy transition business

thought leadership

Time is of the essence when it comes to scaling energy transition businesses in Houston — at least that's what a group of panelists agreed on at a recent event from the Greater Houston Partnership.

The GHP's Future of Global Energy event, which took place on October 9, featured a panel entitled, "Epicenter of Energy Innovation for Scale" and was moderated by Barbara Burger, former president of Chevron Technology Ventures and current startup adviser and mentor. Joining Burger was Kristina Lund, president of Pattern Energy; Brooke Vandygriff, COO of HIF Global: and Bud Vos, CEO of MetOx International. All three companies have and plan to continue scaling in Houston.

The conversation covered some of the unique achievements each of the panelists' companies have reached recently, including HIF Global's millions raised to create e-fuels, MetOx's $25 million series B extension, and Pattern Energy's Southern Spirit project scoring $360 million from the Department of Energy to connect Texas's ERCOT to other states.

After covering the momentum each company has right now, Burger asked each of the panelists why Houston makes sense as a place for scaling their energy transition business.

"The U.S. has a great regulatory environment, ERCOT specifically. Texas is in the business of permitting projects," Vandygriff says. "If you take the right steps, you can get your permits. They are very responsive to attracting and recruiting businesses here."

Also attractive is Houston's existing energy workforce. Even when it comes to technology roles, Houston delivers.

"There is great tech talent here," Vos says, pointing out that Bill Gates called Houston the "Silicon Valley of energy" when he was here for CERAWeek. "I think there's an element of that that's very true. There's a lot innovation, there's a lot of creative thinking, and being able to come out of these businesses with huge momentum then go into startups and innovate is a culture change that I think Houston is going through."

The panelists, most of whom are not Houston natives, agreed in a welcoming culture within the business sector.

"I really think that Houston offers great hospitality, and the energy networks here are so strong," Lund says. "You feel the energy of the city."

$360M DOE grant to fund project that will connect ERCOT to US power grid

powering on

Thanks to recently announced funding, the power grid for the territory served by the Electric Reliability Council of Texas (ERCOT) will be connected to grids in other states.

Officials hope building a 320-mile transmission line that connects the ERCOT electric grid to electric grids in the Southeast will prevent power outages like the massive blackout that occurred in 2022 when a winter storm blasted Texas.

San Francisco-based Pattern Energy says its Southern Spirit project will cost more than $2.6 billion. Full-scale construction is supposed to get underway in 2028, and the project is set to go online in 2031.

The U.S. Department of Energy recently approved up to $360 million for the transmission project. The transmission line will stretch from Texas’ border with Louisiana to Mississippi. It’ll supply about 3,000 megawatts of electricity in either direction. That’s enough power for about 750,000 residential customers during ERCOT’s peak hours.

ERCOT’s more than 54,100 miles of transmission lines supply power to about 90 percent of Texans.

“The U.S. transmission network is the backbone of our nation’s electricity system. Though our grid has served U.S. energy needs for more than a century, our country’s needs are changing,” David Turk, under secretary at the Department of Energy, says in a news release.

“DOE’s approach to deploying near-term solutions and developing long-term planning tools will ensure our electric grid is more interconnected and resilient than ever before,” Turk adds, “while also supporting greater electricity demand.”

The other three projects that recently received funding from the DOE include:

Aroostook Renewable Project, which will construct a new substation in Haynesville, Maine, and a 111-mile transmission line connecting to a substation in Pittsfield, Maine.
Cimarron Link, a 400-mile HVDC transmission line from Texas County, Oklahoma to Tulsa, Oklahoma
Southline, which will construct a 108-mile transmission line between Hidalgo County, New Mexico, and Las Cruces, New Mexico. The DOE previously supported a 175-mile line from Hidalgo County, New Mexico, to Pima County, Arizona, in Southline Phase 1 on the first round of the Transmission Facilitation Program.

This month's funding completes the $2.5 billion in awards from the Transmission Facilitation Program which is administered through the Building a Better Grid Initiative that launched in January 2022. Its mission has been to develop nationally significant transmission lines, increase resilience by connecting regions of the country and improve access to clean energy sources, according to the DOE.

Earlier this year, ERCOT, which manages 90 percent of Texas’ power supply, forecasted a major spike in demand for electricity over the next five to seven years

GE business to fill order for turbines to power Western Hemisphere's largest wind project

winds in the west

A business to be spun off by General Electric will build hundreds of turbines for what will be the largest wind project in the Western Hemisphere, part of a massive equipment order and long-term service agreement with the global renewable-energy giant Pattern Energy.

GE Vernova, which recently became a high-level partner of Boston and Houston-based Greentown Labs, announced the agreement Tuesday, saying it is the largest onshore wind turbine order received by the company, both in quantity and in the amount of electricity that the 674 turbines will eventually generate when the SunZia Wind Project comes online in 2026.

GE Vernova will tap its factory in Pensacola, Florida, for the large order, as well as tower manufacturing operations in New Mexico, Colorado, and Texas. Overall, 15 suppliers are on board for providing the necessary parts to make each turbine.

Construction already is underway on the SunZia wind farm and an associated multibillion-dollar transmission line that will funnel power to populated markets in the western United States. Pattern Energy, which has a Houston office, just weeks ago announced that it had closed on $11 billion in financing for the projects.

Backers see SunZia — described as an energy infrastructure undertaking larger than that of the Hoover Dam — as a pivotal project. The venture has attracted significant financial capital and stands to boost the percentage of the nation's electricity that comes from renewable sources amid escalating state and federal energy mandates.

Still, some Native American tribes and environmentalists worry about the location of a 50-mile (80-kilometer) segment of the transmission line where it will pass through Arizona's San Pedro Valley. The federal government already had approved the siting, but tribal leaders said there should have been more consultation.

In December, the U.S. Energy Department reported that the private sector over the past three years has announced investments of more than $180 billion in new or expanded clean energy manufacturing projects across the nation, including spending on development of larger, higher capacity wind turbines. GE has been among the companies to take advantage of tax credits included in the federal Inflation Reduction Act.

However, after years of record growth, the industry group American Clean Power expects less land-based wind to be added in the U.S. by year’s end — about enough to power 2.7 million to 3 million homes.

While companies are taking advantage of government incentives now, it can take years to bring projects online, the industry group said.

The SunZia Wind Project will span three counties in rural New Mexico. Crews already are constructing the concrete platforms that will support the turbines, and developers expect the first turbines to rise this autumn.

Pattern Energy CEO Hunter Armistead said the project will serve as a backbone for a cleaner, more reliable grid for customers across the western U.S. The company already has signed long-term power purchase agreements with Shell Energy North America and the University of California for a portion of the electricity that will be generated.

“Construction is in full swing on SunZia, using American-made turbine components and creating thousands of good-paying new jobs — a big win for the growing clean energy economy,” Armistead said in a statement.

Vic Abate, president and CEO of the company's wind business, called the venture historic.

“This project demonstrates GE Vernova’s ability to deliver on our workhorse strategy in onshore wind — producing fewer variants in large quantities at scale to drive quality and reliability across the fleet for our customers," he said in a statement.

In all, the company has more than 55,000 turbines installed worldwide.

The company has been working with Pattern Energy for the past 18 months on site layouts that are designed to maximize the performance of the turbines in central New Mexico and to ensure the supply chain can keep up with manufacturing demands.

GE Vernova consultants also have been working on interconnection with the transmission line, and the company's financial arm provided a tax equity loan commitment that helped to solidify financing for the project.

Houston energy and innovation leaders come together at Argonne National Laboratory

The view from heti

Nearly 20 companies from Houston, ranging from global multinationals to innovative startups, joined the team at Argonne National Laboratory in Lemont, Illinois, for a full day of meetings, discussions, and networking focused on advancing innovation, commercialization, and industry collaboration.

The fly-in organized by the Houston Energy Transition Initiative, provided a unique opportunity for companies to engage directly with Argonne researchers, technical experts, and leadership while gaining a deeper understanding of the laboratory’s world-class capabilities. Participants explored how national laboratories can help bridge the gap between breakthrough research and commercial deployment, particularly in areas critical to U.S. competitiveness and economic growth.

The significance of this engagement extends beyond a single visit. While the U.S. Department of Energy operates 17 national laboratories, none is located along the Gulf Coast, a region uniquely home to industry, infrastructure, and energy systems at commercial scale. HETI’s continued work with the national laboratories helps bridge that geographic and operational gap by connecting world-class scientific research with companies that understand how to scale and deploy technologies. The Argonne fly-in also created space to address practical barriers to collaboration, including complex agreements and lengthy contracting timelines, and to explore ways to establish partnership frameworks more efficiently.

Explore HETI’s key takeaways from the fly-in:

1. Scaling Technologies for Commercial Use

A central theme was the importance of scale-up infrastructure and the role Argonne plays in helping companies reduce technical and manufacturing risks. Participants learned how facilities such as the Materials Engineering Research Facility (MERF) support the transition from laboratory discoveries to pilot-scale production and ultimately commercial manufacturing. These capabilities are especially valuable for companies working to move promising technologies from concept to market.

The discussions also highlighted Argonne’s extensive work in critical materials, battery recycling, advanced manufacturing, and supply chain resilience. Attendees learned about initiatives including the ReCell Center, AI-enabled materials discovery, and advanced modeling tools that can help businesses understand supply chain vulnerabilities and evaluate mitigation strategies. These capabilities have applications across energy, chemicals, manufacturing, semiconductors, defense, and emerging technologies.

2. Creating Pathways for Collaboration

Another key takeaway was the importance of engaging early. Companies do not need to arrive with a fully developed project or solution. Argonne offers multiple pathways for collaboration, including sponsored research, user facility access, technology licensing, pilot-scale testing, and Cooperative Research and Development Agreements (CRADAs). These partnerships help companies access specialized expertise, facilities, and analytical tools that can accelerate innovation and commercialization

3. Building Connections Across Industry and Research

The fly-in reinforced the value of relationship building. Bringing together nearly 20 organizations in one place created meaningful opportunities for collaboration, knowledge sharing, and identifying future projects.

The conversations throughout the day demonstrated a shared commitment to strengthening domestic innovation, developing resilient supply chains, and creating pathways to bring new technologies to market.

Fervo produces first geothermal power at flagship Utah project

energy milestone

Fervo Energy’s flagship project in Utah just generated its first geothermal power.

The electricity is now flowing to the power grid from one of Cape Station’s three generation units, Houston-based Fervo said in a news release. This represents an early but important milestone for the project, as the unit isn’t scheduled to deliver contracted power until Oct. 1.

The achievement, coming four months after Fervo’s roughly $2.2 billion IPO, demonstrates the viability of enhanced geothermal systems (EGS).

“This is a gamechanger for the geothermal industry. It establishes EGS as the defining new power generation technology of our time, and we believe it shows that the commercial and technical maturity of EGS is ready to meet the urgent need for reliable, clean power,” Tim Latimer, co-founder and CEO of Fervo, said in the release.

The plant’s two other units are scheduled to launch commercial operations on Jan. 1.

The three units make up the project’s 99-megawatt first phase. The next phase, which will add 400 megawatts of capacity, is under construction. The second phase is set to go online in 2028.

Altogether, Cape Station will provide more than 4 gigawatts of capacity, with 900 megawatts already spoken for. The 900 megawatts of contracted electricity would be enough to power nearly 1 million U.S. homes per year.

“Cape Station works because we treated the subsurface like an engineering challenge,” Jack Norbeck, co-founder and chief technology officer of Fervo, added in the release. “Years of drilling, completion design, subsurface modeling, and flow testing led to this moment, and this is the validation that matters most.”

Enhanced geothermal continuously draws on heat that’s deep underground, producing electricity around the clock regardless of weather or time of day. That makes it one of the only carbon-free resources capable of constant power delivery, which is critical for data centers and AI infrastructure.
