More than a dozen Houston-based companies are sharing the spotlight in U.S. News and World Report's collection of the "Best Companies to Work For" in 2024-2025, including several of the Bayou City’s energy companies.

The annual report examines publicly-traded companies around the world to determine the best employers based on six metrics including work-life balance and flexibility; quality of pay and benefits; job and company stability; career opportunities and professional development; and more. The companies were not ranked, but included based on reader surveys and publicly available data about each workplace.

New for the 2024-2025 report, U.S. News analyzed 549 companies across 29 different lists, including the overall best companies list — which includes the best 300 companies across the U.S., the United Kingdom, Ireland, Switzerland, Luxembourg, and Bermuda — 24 industry-specific lists, and four regional lists.

There were 16 total companies based around Houston that made the lists, with the majority being based in the city, while one each were located in Spring and The Woodlands.

In addition to being included in the overall "Best Companies" list, Marathon Oil earned recognition in the industry-specific "Best in Energy" list and the "Best Companies in the South" list.

A second Houston-based energy company earning a spot among the top employers is Occidental (also known as Oxy). The petroleum corporation, which has been in operation since 1920, has nearly 12,600 employees and brings in $27,43 billion in revenue every year.

According to U.S. News, Occidental offers many financial, health and wellness, and workplace benefits including 401k matching, tuition assistance, an employee assistance program, flexible work arrangements, and much more. The company was also given a "Top Quality of Pay" designation.

Occidental appeared in U.S. News' "Best in Mining and Raw Materials," the overall "Best Companies," and "Best Companies in the South" lists.

Greentown Labs names first head of philanthropy

new hire

Greentown Labs has named its first-ever head of philanthropy in an "all hands on deck" move to advance philanthropic support for climatetech ventures.

Stacey Harris will join the clean energy incubator and brings more than 15 years of experience to the role, having led major partnerships at organizations like Make-A-Wish International, Movember, Net Impact and the Greater Phoenix Economic Council, according to a release from Greentown.

Harris will be based out of Greentown's Boston-area incubator but will support both its Texas and Massachusetts locations. Greentown maintains headquarters in Houston and Somerville, Massachusetts.

“Stacey brings national reach, local roots, and the entrepreneurial spirit we need,” Georgina Campbell Flatter, CEO of Greentown, said in the release. “She understands that philanthropy isn’t just about raising funds—it’s about building a movement, sustaining an ecosystem, and accelerating change together.”

In her new role, Harris will be tasked with designing and leading a philanthropic strategy that aligns with Greentown's corporate partnerships.

The incubator said in the release that Harris's hire is coming at a "pivotal moment," and the organization is "calling for all hands on deck" to support the clean energy space. "This includes inspiring states and local governments to lean in, individuals and family offices to step up, foundations to mobilize resources, and industry to invest boldly," the release states.

"Philanthropy has the unique power to accelerate innovation where it matters most—by backing the people and ideas that can change the world,” Harris added in the release. “At Greentown, I see an incredible opportunity to partner with local communities in Massachusetts and Texas, while also mobilizing catalytic funds that fuel entrepreneurs globally. I’m energized to work across donors, foundations, and industry to ensure these founders have what they need to go further, faster—together.”

Harris is the latest in a series of new hires for Greentown.

Lawson Gow, founder of The Cannon co-working space and former managing partner at Helium Capital, was named Greentown's Head of Houston in July. Flatter was also named as the organization's new CEO in February, after Naheed Malik was named its new CFO in January.

Houston companies team up on $700M floating solar projects in Texas

float on

Diamond Infrastructure Solutions has given Third Pillar Solar exclusive rights to access Diamond’s Texas reservoirs for the possible launch of utility-scale floating solar installations. Both companies are based in the Houston area.

The potential investment in the floating solar project exceeds $700 million, and the project is expected to generate up to 500 megawatts of solar energy.

“Our agreement with Third Pillar marks a bold step forward in how we think about infrastructure and sustainability. By transforming underutilized water surfaces into clean energy assets, Diamond is advancing its commitment to innovation while delivering long-term value,” Ed Noack, CEO of Diamond Infrastructure Solutions, said in the release.

Dow Chemical Co. and a fund directed by Macquarie Asset Management announced the formation of Diamond in 2024. Dow holds a majority stake in Diamond, which owns Gulf Coast infrastructure used by Dow and other industrial customers at five locations in Texas and Louisiana.

The solar installations are scheduled to be built and in operation by the end of the decade.

The agreement between Diamond and Three Pillar “demonstrates the growing appetite for utility-scale energy solutions and highlights how floating solar can enhance and transform the value of existing infrastructure, all while providing cost-competitive energy, preserving agricultural land, reducing evaporation losses, and existing out of public view,” Jaimeet Gulati, CEO of Third Pillar, added in the realease.

Founded in 2022 and majority-owned by renewable energy investor Glentra Capital, Third Pillar develops, owns and operates floating photovoltaic solar installations. The installations are designed to float in places such as wastewater lagoons, reclaimed sand and gravel pits and industrial reservoirs. Third Pillar’s development pipeline contains more than 60 projects.
