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.

Alabama-based renewable fuels company to move HQ to Houston

welcome to houston

An Alabama-based clean tech company is moving its headquarters to Houston.

Alléo Energy announced that it will move its headquarters from Bay Minette, Alabama, to Houston's Ion District. The company develops carbon-negative fuels and renewable commodities through its conversion technology that turns wood waste and cellulosic feedstocks into high-energy, high-yield syngas.

The news comes after Alléo announced the appointment of Benjamin Cowart as its new CEO. Cowart will succeed Alléo founder Simeon Chow, who will serve as president.

“Ben doesn’t need to be sold on carbon-negative fuels; he’s already building in this exact space, and he’s thrived through some of the hardest conditions the industry has faced,” Chow said in a news release. “He knows how to scale and he knows the capital markets that finance them; he turns the hurdles that stall other companies into momentum. Bringing a leader of his caliber in as CEO is a defining, energizing moment.”

Cowart previously founded Houston-based renewables Vertex Energy Inc. The company went public on the Nasdaq exchange in 2009 through a reverse merger. He served as chairman and CEO of the company, which was later taken private by a consortium led by BlackRock.

Cowart also founded EVH Corp., a venture platform focused on building in hydrogen, methanol, sustainable aviation fuel (SAF), and low-carbon marine fuels.

“I’ve spent my career turning advanced process technology into high-performing enterprises that deliver both economic and environmental returns in an industry defined by headwinds,” Cowart added in the release. “The winners in energy transition aren’t the ones with the best headline; they’re the ones that keep their economics intact when subsidies move, feedstock prices swing, and capital gets expensive. Alléo is well-built for that. I’ve rarely seen a technology company this well positioned for what the market is demanding. The science is proven; now it’s about disciplined execution, financing, and building more plants. This is the work I love most.”

Alléo plans to scale its proprietary conversion technology. The company commissioned the first phase of its Alabama facility in 2023, which produced renewable diesel made entirely from wood waste, which could be converted to SAF.

The company says that it has $50 million invested in initial research and development, and that additional facilities are in the planning stages.

J.J. Watt takes a run at energy sector with Base Power investment

power play

Since retiring from the NFL three years ago, Houston Texans legend J.J. Watt has been exploring a new field—investing.

In 2023, the former defensive end and current CBS Sports football analyst bought a stake in English soccer team Burnley FC. A year later, he invested in the PopUp Bagels chain.

This summer, Watt made what may be his highest-profile investment yet. He contributed to a $1 billion Series D round for Austin-based energy startup Base Power, which has an office in Houston. It’s Watts’ first investment in the energy sector.

“I like companies that solve real problems, and Base is lowering power bills, protecting families, and building the whole thing themselves right here in Texas,” Watt said in a company news release.

“What impressed me wasn’t just how fast they’ve grown,” he adds. “It’s that they’ve already saved Texans millions on their power bills and kept thousands of homes running when the lights went out. That’s why I invested.”

Base Power is building a distributed network of residential batteries that’s designed to strengthen the grid and lower electrical bills. The startup now powers more than 30,000 homes in Texas, including the Houston area, and recently expanded to Illinois.

Base Power’s $1 billion round lifted its valuation to $13 billion. Since being founded in 2023, the startup has raised more than $2.5 billion.

“JJ is a legend in this state, and he earned that as much for how he shows up off the field as for what he did on it,” says Zach Dell, co-founder and CEO of Base Power. "He spent a full day with us asking every hard question he could think of, and then he switched to Base himself. We’re glad to have him partnering with us.”

Zach Dell is the only son of Austin billionaire Michael Dell, chairman and CEO of Round Rock-based Dell Technologies. Michael Dell grew up in Bellaire.

Leading energy companies power Houston's presence on Fortune Global 500

world class

Nine Houston companies landed on the 2026 Fortune Global 500 list, which ranks the world's largest corporations by revenue for the 2025 fiscal year.

Houston's showing on the list was led by energy companies, with Spring’s ExxonMobil claiming the top local spot. Here’s what Houston-area companies made the list, and where they ranked:

  • No. 15 ExxonMobil
  • No. 36 Chevron
  • No. 61 Phillip 66
  • No. 159 Sysco
  • No. 243 ConocoPhillips
  • No. 292 Enterprise Products Partners
  • No. 343 Plains GP Holdings
  • No. 460 SLB
  • No. 481 Hewlett Packard Enterprise

After 12 years as No.1, Arkansas-based Walmart was replaced this year by Seattle-based Amazon in the top spot for 2026. Amazon achieved this by bringing in $700 billion in revenue in 2025, representing a 12 percent increase from the previous year.

"Across global business, we see again and again that the leaders who are winning are those who embrace change,” Alyson Shontell, Fortune's editor in chief and chief content officer, said in a news release. "Amazon has topped the Fortune Global 500, knocking Walmart off its pedestal. The company has continually reinvented itself across new businesses and bold bets—including a $200 billion capital commitment, largely to building its capacity for AI and cloud computing, in this year alone."

The U.S. has 141 companies on the 2026 Fortune Global 500 list, which is the most of any country. Companies in America generated $15.5 trillion in aggregate revenues, a 6 percent increase from the previous year.

The number of women CEOs at Fortune Global 500 companies reached a record of 34 top leaders, who represented 6.8 percent of CEOs of companies on the list.

Technology was the standout growth industry on this year’s list, with 38 companies earning revenues that grew 20 percent to about $4 trillion in 2025, with profits climbing 36 percent to $835 billion. The financial sector accounted for the largest share of companies on the list again, with 123 companies in that sector. The energy sector claimed the No. 2 industry spot with 77 companies making the list.

In June, the Fortune 500 list was released, and Texas led the United States with 57 Fortune 500 companies headquartered in the state, generating $2.8 trillion in combined revenue.
