For most of her career, Ana Amicarella has been the only person in the room who looks like her. But as CEO of Houston-based EthosEnergy, she's changing that.

"The energy sector for sure is highly dominated by men, but I think it's such an exciting environment," Amicarella says on the Houston Innovators Podcast. "What I try to do at every job that I go to is I try to increase representation — diverse representation and females in the company. And I measure that when I started and when I end. I want to be able to make a difference."

Amicarella joined EthosEnergy — which provides rotating equipment services and solutions to the power, oil and gas, and industrial markets — as CEO in 2019 a few years after it was in 2014 as a joint venture between John Wood Group PLC and Siemens Energy AG. Prior to her current role, she served in leadership roles at Aggreko an GE Oil and Gas.

Recently, EthosEnergy announced it's being acquired by New York private equity firm, One Equity Partners, which Amicarella says is very interested in investing into EthosEnergy and its ability to contribute to the energy transition.

"What One Equity Partners will bring is tremendous decisiveness. They won't delay in deciding what is good for the company — I've already seen examples," Amicarella says, adding that the deal hasn't get been finalized. "They are going to make decisions and trust the management team, I think our pace of change will be enormous compared to what it used to be."

While EthosEnergy has customers from traditional oil and gas, she says she leads the company with the energy transition at the top of her mind, and that means being able to grow and evolve.

"One of the behaviors we look to have at EthosEnergy is an ability to be nimble," Amicarella says, "because we know market conditions change. Think of all the things we've had to go through in the last five years."

Houston-based energy equipment service provider EthosEnergy has been acquired by a New York private equity firm.

One Equity Partners announced the acquisition of EthosEnergy, which focuses on rotating equipment services for power generation, energy, industrial, and aerospace and defense industry. The terms of the deal were not disclosed.

Formed in 2014 as a joint venture between John Wood Group and Siemens Energy AG, EthosEnergy, which has 3,600 employees across 23 global sites, provides aftermarket maintenance, repair, and overhaul, or MRO, services as well as outsourced operations and maintenance for power generation and industrial customers operating industrial gas turbines and other similar equipment.

“As we seek to enhance and grow our operations, we are pleased to have OEP backing us as a partner,” EthosEnergy CEO Ana Amicarella says in a news release. “OEP’s longstanding and deep industrial sector expertise will support EthosEnergy as we serve growing needs in a critical industry.”

A middle market PE firm, OEP focuses on the industrial, healthcare, and technology sectors in North America and Europe. The firm was founded in 2001 and spun out of JP Morgan in 2015. It has offices in New York, Chicago, Frankfurt, and Amsterdam.

“EthosEnergy is uniquely positioned to meet the growing maintenance needs of an aging turbine fleet," Ante Kusurin, partner at One Equity Partners, adds. "As energy demand rises, these turbines are being pushed beyond their initial design parameters, creating significant opportunities for EthosEnergy’s flexible, cost-effective services.”

Last year, Amicarella joined EnergyCapital for an interview where she discussed the company's commitment to the energy transition.

"Our focus on sustainability is the right thing to do for our employees, for our customers, and for our communities," she said in the interview.

Houston energy leader on why the industry needs to implement circular economy, other sustainable initiatives

Q&A

When Ana Amicarella took the helm of EthosEnergy in 2019, she had no idea of the challenges that awaited her company, the industry, and the world.

But Amicarella, a former synchronized swimmer from Venezuela who competed in the 1984 Summer Olympics who has three decades of leadership experience at energy companies, has what it took to steer the ship in the choppy waters that was the pandemic, the ongoing energy transition, and more.

In a discussion with EnergyCapital, she shares how she navigated that difficult time and how important she feels it is that energy companies are committed to reducing their carbon footprints — especially through tapping into the circular economy.

EnergyCapital: How have you led EthosEnergy through the past few difficult years? What were the company’s biggest challenges and how did you address them?

Ana Amicarella: Growing EthosEnergy into a global powerhouse with hundreds of millions in turnover within nine years was a formidable task. Since our inception in 2014, we've expanded to 94 locations with 4,000 employees, becoming a leading provider of rotating equipment services in the power, oil, and gas sectors. However, when I assumed the role of CEO in December 2019, the company had evolved into a complex, unwieldy structure with missed opportunities and unsustainable overheads, exacerbated by the COVID-19 pandemic.

Despite the pandemic, we were already on the path to transformation. COVID-19 accelerated our OneEthos strategy, focused on simplifying our business, fostering a new culture, and strengthening client relationships. Extensive listening exercises were held with staff and customers in March 2020 that led to a restructuring plan that was swiftly approved by the board. On July 1, 2020, we launched the new structure, emphasizing that this transformation went beyond organizational changes. Our simplified OneEthos plan focuses on core strengths, eliminating unprofitable activities, embracing cultural principles, and maintaining an unwavering commitment to quality and consistency for our customers. We've also shifted our perspective on capital expenditures, aligning them with energy transition goals to become the preferred partner for critical rotating equipment, offering assistance with end-of-life equipment and carbon footprint reduction as our key value proposition.

EC: How is EthosEnergy future-proofing its business amid the energy transition?

AA: We believe we have a moral responsibility to take a leading role in shaping a better future for us and for generations to come – essentially, we are trying to "Turn on Tomorrow." Our focus on sustainability is the right thing to do for our employees, for our customers, and for our communities. I like to say that behind our company’s name is a team of people. Behind our customers’ names are teams of people. Together we all share common communities, a common environment, and a common reliance on transparent, ethical practices.

A few years ago, we introduced a framework to help us build growth, financial sustainability and deliver long-term value. Our aim is to create value and improve our economic, social, and environmental impact by focusing in the following six areas: Policies and Procedures, Diversity Equity and Inclusion, Environmental Footprint, Engineering Solutions, Alliances and Partnerships, and Third-Party Suppliers. As an example, for Environmental Footprint we are implementing programs to install LED lighting in our facilities, implement more robust environmental recycling and waste reduction plans, and identify other energy efficiency programs around the company. From a third-party supplier’s perspective, we are focused on increasing our spend with minority, women, and veteran-owned businesses. In the last two years, we’ve increased spend in those categories by 35 percent in the US alone. And, we are working towards issuing our first sustainability report in the near future.

EC: How does EthosEnergy help customers shrink their carbon footprint and why is that important to you as a business?

AA: Concerns about climate change have started to exert pressure on conventional business models that follow a linear approach of "take, make, dispose" – a system where we acquire new items, use them, and then discard them when they are no longer needed.

A circular economy approach, on the other hand, disconnects economic activities from excessive material and energy consumption by establishing closed-loop systems where waste and carbon-footprint is minimized, and resources are repeatedly used. Even industries traditionally adhering to linear models, like oil and gas and utilities, can incorporate elements of circularity into their operations. EthosEnergy explores the possibilities that circularity offers to companies in the power generation, oil and gas, and industrial sectors, aiming to revitalize and extend the lifespan of existing assets.

To transition from a linear economy to a circular one, we must focus on three key aspects: optimizing product usage, giving priority to renewable inputs, and effectively recovering by-products and waste.

EC: What sort of technology are you tapping into to help achieve these goals?

AA: The adoption of reusing equipment in the energy industry has room for improvement. There's significant potential for reusing rather than disposing of equipment when it nears decommissioning. Our mission is to offer solutions that are economically, socially, and environmentally beneficial, aimed at prolonging the lifespan of existing equipment. EthosEnergy has already developed a range of solutions for life extension and emissions compliance to help existing assets meet critical targets. This has a noteworthy impact on reducing CO2 emissions in two key ways: first, by avoiding the production of new equipment and thus preventing emissions during manufacturing, and second, by deferring or even eliminating the recycling of older assets.

Additionally, there's an opportunity to enhance the environmental performance of existing assets by increasing their efficiency through regeneration and enabling them to operate with lower-carbon alternative fuels like hydrogen. We've actively collaborated with a university in Italy, Politecnico di Torino, on this front, recognizing that partnerships between universities and industries will play a pivotal role in shaping our future.

We firmly believe that greater collaboration and alignment between business, social, and environmental factors are essential for achieving success in these endeavors.

EC: What’s your leadership style and how do you navigate the challenges that come with being a female CEO in a male-dominated industry?

AA: I would best describe my leadership style as inclusive and engaging. I firmly believe in the power of teamwork and fostering a culture where diverse voices are not only heard but valued. My leadership approach is rooted in transparency, open communication, and a commitment to empowering individuals within the organization to contribute their unique perspectives and talents.

In a male-dominated industry, being relentless is a necessity. I approach challenges with unwavering determination and persistence. I use adversity as motivation to push forward and break down barriers. My relentless pursuit of excellence sets an example for my team and reinforces the idea that gender should never limit one's aspirations.

SLB partners with renewables company to develop next-gen geothermal systems

geothermal partnership

Houston-based energy technology company SLB and renewable energy company Ormat Technologies have teamed up to fast-track the development and commercialization of advanced geothermal technology.

Their initiative focuses on enhanced geothermal systems (EGS). These systems represent “the next generation of geothermal technology, meant to unlock geothermal energy in regions beyond where conventional geothermal resources exist,” the companies said in a news release.

After co-developing EGS technology, the companies will test it at an existing Ormat facility. Following the pilot project, SLB and Nevada-based Ormat will pursue large-scale EGS commercialization for utilities, data center operators and other customers. Ormat owns, operates, designs, makes and sells geothermal and recovered energy generation (REG) power plants.

“There is an urgent need to meet the growing demand for energy driven by AI and other factors. This requires accelerating the path to clean and reliable energy,” Gavin Rennick, president of new energy at SLB, said in a news release.

Traditional geothermal systems rely on natural hot water or steam reservoirs underground, limiting the use of geothermal technology. EGS projects are designed to create thermal reservoirs in naturally hot rock through which water can circulate, transferring the energy back to the surface for power generation and enabling broader availability of geothermal energy.

The U.S. Department of Energy estimates next-generation geothermal, such as EGS, could provide 90 gigawatts of electricity by 2050.

Baker Hughes to provide equipment for massive low-carbon ammonia plant

coming soon

Houston-based energy technology company Baker Hughes has been tapped to supply equipment for what will be the world’s largest low-carbon ammonia plant.

French technology and engineering company Technip Energies will buy a steam turbine generator and compression equipment from Baker Hughes for Blue Point Number One, a $4 billion low-carbon ammonia plant being developed in Louisiana by a joint venture comprising CF Industries, JERA and Mitsui & Co. Technip was awarded a contract worth at least $1.1 billion to provide services for the Blue Point project.

CF, a producer of ammonia and nitrogen, owns a 40 percent stake in the joint venture, with JERA, Japan’s largest power generator, at 35 percent and Mitsui, a Japanese industrial conglomerate, at 25 percent.

The Blue Point Number One project, to be located at CF’s Blue Point ammonia production facility, will be capable of producing about 1.4 million metric tons of low-carbon ammonia per year and permanently storing up to 2.3 million metric tons of carbon dioxide.

Construction of the ammonia-making facility is expected to start in 2026, with production of low-carbon ammonia set to get underway in 2029.

“Ammonia, as a lower-carbon energy source, is poised to play a pivotal role in enabling and accelerating global sustainable energy development,” Alessandro Bresciani, senior vice president of energy equipment at Baker Hughes, said in a news release.

Earlier this year, British engineering and industrial gas company Linde signed a long-term contract to supply industrial gases for Blue Point Number One. Linde Engineering Americas is based in Houston.

Houston expert asks: Is the Texas grid ready for the future?

Guets Column

Texas has spent the past five years racing to strengthen its electric grid after Winter Storm Uri exposed just how vulnerable it was. Billions have gone into new transmission lines, grid hardening, and a surge of renewables and batteries. Those moves have made a difference, we haven’t seen another systemwide blackout like Uri, but the question now isn’t what’s been done, it’s whether Texas can keep up with what’s coming.

Massive data centers, electric vehicles, and industrial projects are driving electricity demand to unprecedented levels. NERC recently boosted its 10-year load forecast for Texas by more than 60%. McKinsey projects that U.S. electricity demand will rise roughly 40% by 2030 and double by 2050, with data centers alone accounting for as much as 11-12% of total U.S. electricity demand by 2030, up from about 4% today. Texas, already the top destination for new data centers, will feel that surge at a greater scale.

While the challenges ahead are massive and there will undoubtedly be bumps in the road (some probably big), we have an engaged Texas legislature, capable regulatory bodies, active non-profits, pragmatic industry groups, and the best energy minds in the world working together to make a market-based system work. I am optimistic Texas will find a way.

Why Texas Faces a Unique Grid Challenge

About 90% of Texas is served by a single, independent grid operated by ERCOT, rather than being connected to the two large interstate grids that cover the rest of the country. This structure allows ERCOT to avoid federal oversight of its market design, although it still must comply with FERC reliability standards. The trade-off is limited access to power from neighboring states during emergencies, leaving Texas to rely almost entirely on in-state generation and reserves when extreme weather hits.

ERCOT’s market design is also different. It’s an “energy-only” market, meaning generators are paid for electricity sold, not for keeping capacity available. While that lowers prices in normal times, it also makes it harder to finance backup, dispatchable generation like natural gas and batteries needed when the wind isn’t blowing or the sun isn’t shining.

The Risks Mounting

In Texas, solar and wind power supply a significant percentage of electricity to the grid. As Julie Cohn, a nonresident scholar at the Baker Institute, explains, these inverter‑based resources “connect through power electronics, which means they don’t provide the same physical signals to the grid that traditional generators do.” The Odessa incidents, where solar farms tripped offline during minor grid disturbances, showed how fragile parts of this evolving grid can be. “Fortunately, it didn’t result in customer outages, and it was a clear signal that Texas has the opportunity to lead in solving this challenge.”

Extreme weather adds more pressure while the grid is trying to adapt to a surge in use. CES research manager Miaomiao Rimmer notes: “Hurricane frequencies haven't increased, but infrastructure and population in their paths have expanded dramatically. The same hurricane that hit 70 years ago would cause far more damage today because there’s simply more in harm’s way.”

Medlock: “Texas has made significant strides in the last 5 years, but there’s more work to be done.”

Ken Medlock, Senior Director of the Center for Energy Studies at Rice University’s Baker Institute, argues that Texas’s problem isn’t a lack of solutions; it’s how quickly those solutions are implemented. He stresses that during the January 2024 cold snap, natural gas kept the grid stable, proving that “any system configuration with sufficient, dispatchable generation capacity would have kept the lights on.” Yet ERCOT load has exceeded dispatchable capacity with growing frequency since 2018, raising the stakes for future reliability.

Ken notes: “ERCOT has a substantial portfolio of options, including investment in dispatchable generation, storage near industrial users, transmission expansion, and siting generation closer to load centers. But allowing structural risks to reliability that can be avoided at a reasonable cost is unacceptable. Appropriate market design and sufficient regulatory oversight are critical.” He emphasizes that reliability must be explicitly priced into ERCOT’s market so backup resources can be built and maintained profitably. These resources, whether natural gas, nuclear, or batteries, cannot remain afterthoughts if Texas wants a stable grid.

Building a More Reliable Grid

For Texas to keep pace with rising demand and withstand severe weather, it must act decisively on multiple fronts, strengthening its grid while building for long-term growth.

  • Coordinated Planning: Align regulators, utilities, and market players to plan decades ahead, not just for next summer.
  • Balancing Clean and Reliable Power: Match renewable growth with flexible, dispatchable generation that can deliver power on demand.
  • Fixing Local Weak Spots: Harden distribution networks, where most outages occur, rather than focusing only on large-scale generation.
  • Market Reform and Technology Investment: Price reliability fairly and support R&D to make renewables strengthen, not destabilize, the grid.

In Conclusion

While Texas has undeniably improved its grid since Winter Storm Uri, surging electricity demand and intensifying weather mean the work is far from over. Unlike other states, ERCOT can’t rely on its neighbors for backup power, and its market structure makes new dispatchable resources harder to build. Decisive leadership, investment, and reforms will be needed to ensure Texas can keep the lights on.

It probably won’t be a smooth journey, but my sense is that Texas will solve these problems and do something spectacular. It will deliver more power with fewer emissions, faster than skeptics believe, and surprise us all.
