Chevron gets green light on $53 billion Hess acquisition

Mega Deal

Chevron has scored a critical ruling in Paris that has given it the go-ahead for a $53 billion acquisition of Hess and access to one of the biggest oil finds of the decade.

Chevron said Friday that it completed its acquisition of Hess shortly after the ruling from the International Chamber of Commerce in Paris. Exxon had challenged Chevron’s bid for Hess, one of three companies with access to the massive Stabroek Block oil field off the coast of Guyana.

“We disagree with the ICC panel’s interpretation but respect the arbitration and dispute resolution process,” Exxon Mobil said in a statement on Friday.

Guyana is a country of 791,000 people that is poised to become the world’s fourth-largest offshore oil producer, placing it ahead of Qatar, the United States, Mexico and Norway. It has become a major producer in recent years.

Oil giants Exxon Mobil, China’s CNOOC, and Hess squared off in a heated competition for highly lucrative oil fields in northern South America.

With Chevron getting the green light on Friday, it is now one of the major players in the Stabroek.

“We are proud of everyone at Hess for building one of the industry’s best growth portfolios including Guyana, the world’s largest oil discovery in the last 10 years, and the Bakken shale, where we are a leading oil and gas producer,” former Hess CEO John Hess said in a statement. “The strategic combination of Chevron and Hess creates a premier energy company positioned for the future.”

Chevron also said that on Thursday the Federal Trade Commission lifted its earlier restriction, clearing the way for John Hess to join its board of directors, subject to board approval.

Chevron announced its deal for Hess in October 2023, less than two weeks after Exxon Mobil said that it would acquire Pioneer Natural Resources for about $60 billion.

Chevron said at the time that the acquisition of Hess would add a major oil field in Guyana as well as shale properties in the Bakken Formation in North Dakota.

“Given the significant value we’ve created in the development of the Guyana resource, we believed we had a clear duty to our investors to consider our preemption rights to protect the value we created through our innovation and hard work at a time when no one knew just how successful this venture would become,” Exxon Mobil said Friday. “We welcome Chevron to the venture and look forward to continued industry-leading performance and value creation in Guyana for all parties involved.”

Chevron's stock rose more than 3% before the market open, while shares of Hess surged more than 7%. Exxon's stock climbed slightly.

Investment giant to acquire TXNM Energy for $11.5 billion

m&a moves

Blackstone Infrastructure, an investment giant with $600 million in assets under management, has agreed to buy publicly traded TXNM Energy in a debt-and-stock deal valued at $11.5 billion.

TXNM Energy is the parent company of Lewisville-based Texas New Mexico Power (TNMP), which supplies electricity to more than 270,000 homes and businesses throughout Texas. Its Houston-area service territory includes Alvin, Angleton, Brazoria, Dickinson, Friendswood, La Marque, League City, Sweeny, Texas City and West Columbia.

Once Blackstone Infrastructure wraps up the deal in the second half of 2026, Albuquerque, New Mexico-based TXNM will no longer be a public company. But TNMP’s headquarters will remain in Texas and its rates will continue to be set by the Public Utility Commission of Texas. TNMP was founded in 1934.

Blackstone Infrastructure is affiliated with investment powerhouse Blackstone Inc., which has $1.2 trillion in assets under management and is the world’s largest investment manager.

“TNMP has done an excellent job of meeting its customers’ growing demand for electricity and supporting the communities it serves,” Sean Klimczak, Blackstone’s global head of infrastructure, said in a news release. “We look forward to utilizing our long-term investment commitments to support TNMP as they continue on this path of high-demand growth across Texas.”

During TXNM’s fourth-quarter earnings call in February, Chairwoman and CEO Patricia Vincent-Collawn said the company’s five-year Texas capital investment plan had grown by more than $1 billion.

“Our future is so bright with these increased investment levels that we are now targeting earnings growth of 7 percent to 9 percent through 2029,” Vincent-Collawn said.

“Our financial expectations are driven by the continued expansion of grid infrastructure supporting growth and reliability in our Texas service territory,” she added.

In 2024, TXNM reported revenue of $1.96 billion, up 1.7 percent from the previous year.

Houston-based Calpine Corp. to be acquired in clean energy megadeal

big deal

Baltimore-based nuclear power company Constellation Energy Corp. and Houston-based Calpine Corp. have entered into an agreement where Constellation will acquire Calpine in a cash and stock transaction with an overall net purchase price of $26.6 billion.

The companies say the agreement has the potential to create America’s “largest clean energy provider,” with what is reported to be the largest fleet of U.S. power stations servicing about 2.5 million customers.

“This is an incredible opportunity to bring together top tier generation fleets, leading retail customer businesses and the best people in our industry to help drive a stronger American economy for a cleaner, healthier and more sustainable future,” Andrew Novotny, president and CEO of Calpine, said in a news release.

Calpine is the largest U.S. producer of energy from low-emission natural gas generation and oversees the largest geothermal generation operation in the U.S. Last year it announced plans to build the Baytown Carbon Capture and Storage Project (Baytown CCS Project), a first-of-its-kind carbon capture demonstration facility, as part of a cost-sharing agreement with the U.S. Department of Energy.

Constellation is considered the top clean energy producer in the U.S., which provides 10 percent of the country’s emissions-free energy. The deal will add to Constellation’s already diverse portfolio of zero- and low-emission sources, including nuclear, natural gas, geothermal, hydro, wind, solar, cogeneration and battery storage.

“Both companies have been at the forefront of America’s transition to cleaner, more reliable and secure energy, and those shared values will guide us as we pursue investments in new and existing clean technologies to meet rising demand,” Joe Dominguez, president and CEO of Constellation, said the release. “What makes this combination even more special is it brings together two world-class teams, with the most talented women and men in the industry, who share a noble passion for safety, sustainability, operational excellence and helping America’s families, businesses and communities thrive and grow. We look forward to welcoming the Calpine team upon closing of this transaction.”

Constellation also announced that it will invest in adding more zero-emission energy to the grid to create “the most reliable generation portfolio in the U.S.” It plans to explore new advanced nuclear projects, invest in renewables and increase the output of existing nuclear plants.

“Together, we will be better positioned to bring accelerated investment in everything from zero-emission nuclear energy to battery storage that will power our economy in a way that puts people and our environment first,” Novotny said in a news release. “It’s a win for every American family and business in our newly combined footprint that wants clean and reliable energy. ECP’s commitment to these goals over the last seven years was critical to the progress we have made as a company and to laying a foundation for future growth.”

Houston-based co. closes acquisition of 50 percent stake in Texas cogeneration facility

M&A Moves

Fengate Asset Management announced the financial close on the acquisition of a 50 percent interest in Freeport Power Limited, which owns a 440-megawatt cogeneration facility in Freeport, Texas.

FPL is located near the Freeport Energy Center, which is a 260-megawatt cogeneration facility that is currently owned and managed by Fengate. The two facilities work to provide cost-effective power and steam to Dow’s Freeport site, which is the largest integrated chemical manufacturing complex in the Western Hemisphere.

“We are thrilled to have closed this acquisition, which aligns with our strategy of acquiring behind-the-meter cogeneration projects with strong industrial partners like Dow,” Greg Calhoun, managing director of Infrastructure Investments at Fengate, says in a news release.

Fengate was able to acquire interest in FPL under a strategic operating partnership with asset manager Ironclad Energy. The partnership with Ironclad was established in 2022 to acquire and operate cogeneration, district energy and other power generation projects throughout North America.

“This is our second acquisition with Fengate, and we look forward to continuing our partnership to optimize and expand the portfolio,” Christopher Fanella, president and CFO of Ironclad Energy, says in the release.

Fengate opened its first U.S. office in 2017 in Houston.

“Combined heat and power projects like FPL will continue to play an important role in the U.S. power industry – especially for hard-to-abate industrial sectors – to ensure reliability, efficiency and affordability,” adds in the release.

Reliant partners to expand Texas virtual power plant and home battery use

energy incentives

Houston’s Reliant and San Francisco tech company GoodLeap are teaming up to bolster residential battery participation and accelerate the growth of NRG’s virtual power plant (VPP) network in Texas.

Through the new partnership, eligible Reliant customers can either lease a battery or enter into a power purchase agreement with GoodLeap through its GoodGrid program, which incentivises users by offering monthly performance-based rewards for contributing stored power to the grid. Through the Reliant GoodLeap VPP Battery Program, customers will start earning $40 per month in rewards from GoodLeap.

“These incentives highlight our commitment to making homeowner battery adoption more accessible, effectively offsetting the cost of the battery and making the upgrade a no-cost addition to their homes,” Dan Lotano, COO at GoodLeap, said in a news release.“We’re proud to work with NRG to unlock the next frontier in distributed energy in Texas. This marks an important step in GoodLeap reaching our nationwide goal of 1.5 GW of managed distributed energy over the next five years.”

Other features of the program include power outage plans, with battery reserves set aside for outage events. The plan also intelligently manages the battery without homeowner interaction.

The partnership comes as Reliant’s parent company, NRG, continues to scale its VPP program. Last year, NRG partnered with California-based Renew Home to distribute hundreds of thousands of VPP-enabled smart thermostats by 2035 in an effort to help households manage and lower their energy costs.

“We started building our VPP with smart thermostats across Texas, and now this partnership with GoodLeap brings home battery storage into our platform,” Mark Parsons, senior vice president and head of Texas energy at NRG, said in a the release. “Each time we add new devices, we’re enabling Texans to unlock new value from their homes, earn rewards and help build a more resilient grid for everyone. This is about giving customers the opportunity to actively participate in the energy transition and receive tangible benefits for themselves and their communities.

How Corrolytics is tackling industrial corrosion and cutting emissions

now streaming

Corrosion is not something most people think about, but for Houston's industrial backbone pipelines, refineries, chemical plants, and water infrastructure, it is a silent and costly threat. Replacing damaged steel and overusing chemicals adds hundreds of millions of tons of carbon emissions every year. Despite the scale of the problem, corrosion detection has barely changed in decades.

In a recent episode of the Energy Tech Startups Podcast, Anwar Sadek, founder and CEO of Corrolytics, explained why the traditional approach is not working and how his team is delivering real-time visibility into one of the most overlooked challenges in the energy transition.

From Lab Insight to Industrial Breakthrough

Anwar began as a researcher studying how metals degrade and how microbes accelerate corrosion. He quickly noticed a major gap. Companies could detect the presence of microorganisms, but they could not tell whether those microbes were actually causing corrosion or how quickly the damage was happening. Most tests required shipping samples to a lab and waiting months for results, long after conditions inside the asset had changed.

That gap inspired Corrolytics' breakthrough. The company developed a portable, real-time electrochemical test that measures microbial corrosion activity directly from fluid samples. No invasive probes. No complex lab work. Just the immediate data operators can act on.

“It is like switching from film to digital photography,” Anwar says. “What used to take months now takes a couple of hours.”

Why Corrosion Matters in Houston's Energy Transition

Houston's energy transition is a blend of innovation and practicality. While the world builds new low-carbon systems, the region still depends on existing industrial infrastructure. Keeping those assets safe, efficient, and emission-conscious is essential.

This is where Corrolytics fits in. Every leak prevented, every pipeline protected, and every unnecessary gallon of biocide avoided reduces emissions and improves operational safety. The company is already seeing interest across oil and gas, petrochemicals, water and wastewater treatment, HVAC, industrial cooling, and biofuels. If fluids move through metal, microbial corrosion can occur, and Corrolytics can detect it.

Because microbes evolve quickly, slow testing methods simply cannot keep up. “By the time a company gets lab results, the environment has changed completely,” Anwar explains. “You cannot manage what you cannot measure.”

A Scientist Steps Into the CEO Role

Anwar did not plan to become a CEO. But through the National Science Foundation's ICorps program, he interviewed more than 300 industry stakeholders. Over 95 percent cited microbial corrosion as a major issue with no effective tool to address it. That validation pushed him to transform his research into a product.

Since then, Corrolytics has moved from prototype to real-world pilots in Brazil and Houston, with early partners already using the technology and some preparing to invest. Along the way, Anwar learned to lead teams, speak the language of industry, and guide the company through challenges. “When things go wrong, and they do, it is the CEO's job to steady the team,” he says.

Why Houston

Relocating to Houston accelerated everything. Customers, partners, advisors, and manufacturing talent are all here. For industrial and energy tech startups, Houston offers an ecosystem built for scale.

What's Next

Corrolytics is preparing for broader pilots, commercial partnerships, and team growth as it continues its fundraising efforts. For anyone focused on asset integrity, emissions reduction, or industrial innovation, this is a company to watch.
