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.

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.

Sage Geosystems brings South Texas geothermal plant online

powering up

Houston-based Sage Geosystems, a provider of geothermal power, has begun full operations at its South Texas facility for the San Miguel Electric Cooperative.

Sage says the plant was recently “placed in service,” according to a news release. This means it’s fully built and tested, and ready to generate and supply electricity to the grid.

Since selling its first electricity in Q2 of this year, the facility has been operating for more than four months to evaluate aspects like efficiency and water management. Sage relied on its GeoTwin modeling tool to carry out some of the testing.

The testing demonstrates Sage’s proprietary approach to geothermal power “overcomes one of the industry’s most persistent challenges, high water losses in engineered reservoirs, while delivering the consistent performance required to scale next-generation geothermal,” co-founder and CEO Cindy Taff said in the release.

Sage says the South Texas facility will serve as a model for future projects, including one in Nevada. The Nevada facility will use Sage’s proprietary technology to extract geothermal heat from hot dry rock, creating a reliable, affordable source of carbon-free power.

During the testing period, water losses amounted to less than 10 percent. This low rate indicates most water remains in the system, enabling Sage to capture more usable energy, boost power production and improve the project’s finances, the company says.

“Commercial geothermal isn’t just about creating a reservoir. It’s about creating one whose performance can be engineered, predicted, and consistent,” Lev Ring, the company’s co-founder, president and chief technology officer, said in the release.

Since being founded in 2020, Sage has raised $159 million in outside funding. This includes a more than $97 million Series B round co-led by Ormat Technologies and Carbon Direct Capital.

Two years ago, Sage announced a deal with Meta Platforms, the parent company of Facebook and Instagram, to supply up to 150 megawatts of geothermal power to Meta data centers.

Halliburton Labs adds 3 energy, materials startups to Houston incubator

green team

Three new companies have joined Halliburton Labs, the incubator for early-stage energy and hardtech startups run by Houston energy giant Halliburton.

Halliburton Labs provides the emerging companies with mentorship, industry connections, laboratory access and other resources as they work toward commercialization. The latest companies to join the incubator focus on battery materials, resource recovery and gas separation solutions to address some of the "key bottlenecks in the energy and industrial landscape," according to a news release.

The new members include:

  • Electroflow, a California-based company that produces lithium iron phosphate (LFP) cathode material from lithium brines through its proprietary process. LFPs are critical components in batteries used in electric vehicles, grid storage systems and industrial electrification, according to Halliburton Labs.
  • Osmoses, a Cambridge, Massachusetts-based company that has developed a membrane platform to reduce the energy use, cost and emissions associated with gas separations used in natural gas, hydrogen, helium and other industrial applications
  • SiTration Inc., another Cambridge, Massachusetts-based company that has developed electro-extraction and filtration technologies to recover critical metals like copper directly from mining waste streams more quickly and affordably. Its process has completed successful pilot projects with Tier 1 mining companies in three continents.

"Affordable and reliable molecules are essential building blocks of the energy future. Each company brings a bold, technical solution to a complex industrial challenge. We look forward to helping them scale and deploy their technologies," Andres Cabada, Halliburton Labs managing director, added in the news release.

Halliburton Labs previously added four new members from around the world —Nandina REM, Noon Energy, Proof Energy and Tidal Metals—this spring. Alumni from the incubator include Houston-based companies like NanoTech Materials, which is developing insulation and fireproofing to reduce heat transfer in buildings and outdoor infrastructure; and SolvCor, which develops water additives to improve cooling for data centers and thermal storage.

With the addition of the three new members, the incubator currently supports nine early-stage companies.

Houston companies advance 200MW green ammonia plant in South Texas

coming soon

Two global companies with a major presence in Houston are teaming up on a green ammonia plant in Port of Victoria, Texas.

Topsoe, a Danish company with operations in Houston and Bayport, Texas, has been tapped to provide ammonia synthesis technology for the project being developed by First Ammonia, a New York-based company with offices in Houston and Denmark.

The flagship 200-megawatt plant will use renewable electricity to produce green hydrogen through electrolysis, which will then be combined with nitrogen from a nearby Air Liquide pipeline to make green ammonia, according to First Ammonia. It is expected to serve both U.S. and global markets.

According to First Ammonia, every 100,000 tons of electric ammonia produced avoids approximately 240,000 tons of CO2 emissions compared to fossil ammonia

The Topsoe technology used on site is designed to be able to increase production from 10 percent to 100 percent within 30 minutes, and decrease production at a similar rate, allowing the plant to respond to fluctuations from solar- or wind-based energy sources.

“Topsoe is the world leader in ammonia synthesis, and First Ammonia is delighted to continue our partnership with them in establishing a green ammonia industry in the US and around the world,” Joel Moser, CEO of First Ammonia, said in a news release.

Topsoe has previously signed on to supply its 100-megawatt solid oxide electrolyser (SOEC) to the First Ammonia project. However, the company announced in March that it did not extend the contract after multiple delays.

The First Ammonia project was originally expected to come online by 2027 and to produce 1.1 million tonnes of green ammonia. The project is now expected to reach financial before the end of 2026, with construction slated to begin in 2027 and commercial operations launching by 2029.

“As green ammonia projects move from ambition to execution, operational flexibility becomes increasingly important,” Yassir Ghiyati, chief commercial officer at Topsoe, added in a news release. “We’re proud to support First Ammonia with technology designed to enable efficient and reliable green ammonia production. We look forward to continuing to work with the First Ammonia team to help bring this important U.S project to life.”
