Houston hosted the inaugural Energy + Climate Startup Week in September, which brought together leading energy and climate venture capital investors, industry leaders and startups from around the world to showcase the most innovative companies and technologies that are transforming the energy industry while driving a sustainable, low-carbon energy future.

Repsol was one of the inaugural sponsors for the weeks kick off event that hosted several leading startups. This year marked 25 years of energy innovation for Repsol in the United States. As the energy landscape evolves, Repsol has committed to significant growth in renewable capacity, with an impressive 720 MW of solar and storage capacity already operational and 1.5 GW under construction.

Caton Fenz, CEO for Repsol’s Renewables North America shares more about Repsol’s approach to expanding its renewable footprint, integrating green energy into its core business and leveraging Houston’s unique role as a leader in the energy transition. Here’s an inside look at Repsol’s milestones and future goals in the journey toward decarbonization and a sustainable energy future.

Can you tell us more about Repsol’s strategy for expanding its renewables business?

This year Repsol is celebrating 25 years of energy development in the United States. Across the US, we have a team of more than 800 employees, with more than 130 employees working in the renewables business specifically.

Repsol’s growth ambition in the US renewable energy market is significant. Since launching our renewables activity in the US three years ago, we have installed more than 720 MW of solar generation and energy storage capacity. Today we have more than 1.5 GW of additional solar and energy storage capacity under construction, and more than 20 GW of solar, wind and energy storage in development across 13 states.

How does Repsol plan to integrate renewable energy sources into its broader business model?

Repsol Renewables operates in accordance with Repsol’s values and strategies. Renewable energy generation is one of the pillars of Repsol’s decarbonization strategy. Repsol will invest between €3 and 4 billion to organically develop its global project portfolio and aims to reach between 9,000 MW and 10,000 MW of installed capacity by 2027. Of this, 30% will be in the United States.

With these objectives in mind, we have been able to accelerate the development of wind, solar, and energy storage across the US market and the globe. By expanding our renewable energy business, we can further meet record demand growth for renewable energy.

What are the key projects or milestones that have been achieved within Repsol’s renewables portfolio so far?

Earlier this year, we announced the commercial operation of Frye Solar, our largest solar project worldwide. This project, located in Swisher County, Texas, has a total capacity of 637 MW. And as noted above, we have an additional 1.4 GW of projects under construction currently. These major energy infrastructure projects are indicative of the scale of our operations in the US.

Why does Repsol believe being located in Houston is critical for its business, particularly in the energy transition?

Repsol is proudly committed to Houston’s role in developing and delivering energy and value for the world. Houston is known as the Energy Capital of the World and over the next 10 years, we’ll see it be known as the Energy Transition Capital of the World. With Repsol’s Renewables North America business located in downtown Houston, we have access to talent and partnerships in a booming city filled with energy experts.

Why does Repsol see value in participating in Houston Energy + Climate Startup Week?

At Houston Energy + Climate Startup Week, Repsol Renewables is honored to support and learn from leaders and investors in the energy and climate industry. We believe it is important to continuously invest in talent, ideas, and collaboration across the energy value chain as we pursue our net zero by 2050 goal.

Repsol to acquire Houston-based renewable energy platform

M&A Move

Spanish energy giant Repsol is breaking into the U.S. market for onshore wind power with its $768 million deal to purchase Houston-based renewable energy startup ConnectGen.

Repsol is buying ConnectGen from Quantum Capital Group, a Houston-based private equity firm that focuses on energy investments, according to a September 8 news release. Quantum’s renewable energy arm, 547 Energy, owns ConnectGen.

ConnectGen, founded in 2018, operates 278 megawatts of solar energy projects in Arizona, California, and Nevada. Its nationwide development pipeline features more than 20,000 megawatts of wind power, solar power, and energy storage projects.

“All of us at Quantum and 547 Energy are looking forward to watching Repsol convert these development projects into operating assets that will help power the American economy with clean renewable electricity over the next decade,” says Wil VanLoh, founder, chairman, and CEO of Quantum.

Quantum and its affiliates have managed more than $22 billion in equity investments since the firm was founded in 1998.

Once the deal tentatively closes by the end of 2023, current ConnectGen employees, including senior executives, are expected to join Repsol’s renewable energy team. Caton Fenz has been CEO of ConnectGen since 2019. He previously was the startup’s chief development officer.

“The addition of ConnectGen accelerates our commitment to renewable generation in one of the markets with the greatest potential for future growth. In that sense, bringing on board its valuable team of experts is key to [ensuring] our successful future growth with robust profitability in the market,” says Josu Jon Imaz, CEO of Repsol.

Repsol has targeted 20,000 megawatts of installed global capacity for renewable energy by 2030. The company owns 245 megawatts of renewable energy assets in the U.S. and 2,000 megawatts worldwide.

ConnectGen’s capabilities build on Repsol’s 2021 purchase of a 40 percent stake in Chicago-based Hecate Energy, which develops solar power generation and energy storage projects.

Repsol aims to operate 2,000 megawatts of installed renewable energy capacity in the U.S. by 2025 and more than 8,000 megawatts by 2030. Aside from the U.S., Repsol owns renewable energy assets in Chile, Italy, Portugal, and Spain.

In the U.S., Repsol, ConnectGen, and other companies are capitalizing on tax credits contained in the federal Inflation Reduction Act of 2022 that are designed to spark development of clean energy projects. The law earmarks nearly $400 billion in federal funding for clean energy initiatives.

A new study funded by the BlueGreen Alliance, a group backed by labor unions and environmental organizations, indicates the law could add more than 1.5 million jobs in the solar and wind power sectors by 2035. Tens of thousands of these jobs will undoubtedly be created in Texas.

The White House estimates the Inflation Reduction Act will spur $66.5 billion in Texas investments in large-scale clean power generation and storage projects between now and 2030.

“Strengthening our energy security advances two goals: It lowers costs for all Americans by ensuring a resilient and affordable supply of clean energy, and it fosters American innovation in difficult-to-decarbonize sectors,” Lily Batchelder, assistant secretary for tax policy at the U.S. Treasury Department, said in a recent update about the law.

Here's how Houston's energy and innovation sectors fared in the 2025 Texas legislative session

bills, bills, bills

The Greater Houston Partnership is touting a number of victories during the recently concluded Texas legislative session that will or could benefit the Houston area. They range from millions of dollars for energy projects to billions of dollars for dementia research.

“These wins were only possible through deep collaboration, among our coalition partners, elected officials, business and community leaders, and the engaged members of the Partnership,” according to a partnership blog post. “Together, we’ve demonstrated how a united voice for Houston helps drive results that benefit all Texans.”

In terms of business innovation, legislators carved out $715 million for nuclear, semiconductor, and other economic development projects, and a potential $1 billion pool of tax incentives through 2029 to support research-and-development projects. The partnership said these investments “position Houston and Texas for long-term growth.”

"Nuclear power renaissance"

House Bill 14 (HB 14), for instance, aims to lead a “nuclear power renaissance in the United States,” according to Texas Gov. Greg Abbott’s office. HB 14 establishes the Texas Advanced Nuclear Energy Office, and allocates $350 million for nuclear development and deployment. Two nuclear power plants currently operate in Texas, generating 10 percent of the energy that feeds the Electric Reliability Council Texas (ERCOT) power grid.

“This initiative will also strengthen Texas’ nuclear manufacturing capacity, rebuild a domestic fuel cycle supply chain, and train the future nuclear workforce,” Abbott said in a news release earlier this year.

One of the beneficiaries of Texas’ nuclear push could be Washington, D.C.-based Last Energy, which plans to build 30 micro-nuclear reactors near Abilene to serve power-gobbling data centers across the state. Houston-based Pelican Energy Partners also might be able to take advantage of the legislation after raising a $450 million fund to invest in companies that supply nuclear energy services and equipment.

Reed Clay, president of the Texas Nuclear Alliance, called this legislation “the most important nuclear development program of any state.”

“It is a giant leap forward for Texas and the United States, whose nuclear program was all but dead for decades,” said Clay. “With the passage of HB 14 and associated legislation, Texas is now positioned to lead a nuclear renaissance that is rightly seen as imperative for the energy security and national security of the United States.”

Infrastructure

In the infrastructure arena, state lawmakers:

Approved $265 million for Houston-area water and flood mitigation projects, including $100 million for the Lynchburg Pump Station.
Created the Lake Houston Dredging and Maintenance District.
Established a fund for the Gulf Coast Protection District to supply $550 million for projects to make the coastline and ship channel more resilient.

Dementia institute

One of the biggest legislative wins cited by the Greater Houston Partnership was passage of legislation sponsored by Sen. Joan Huffman, a Houston Republican, to provide $3 billion in funding over 10 years for the Dementia Prevention and Research Institute of Texas. Voters will be asked in November to vote on a ballot initiative that would set aside $3 billion for the new institute.

The dementia institute would be structured much like the Cancer Prevention and Research Institute of Texas (CPRIT), a state agency that provides funding for cancer research in the Lone Star State. Since its founding in 2008, CPRIT has awarded nearly $3.9 billion in research grants.

“By establishing the Dementia Prevention and Research Institute of Texas, we are positioning our state to lead the charge against one of the most devastating health challenges of our time,” Huffman said. “With $3 billion in funding over the next decade, we will drive critical research, develop new strategies for prevention and treatment, and support our healthcare community. Now, it’s up to voters to ensure this initiative moves forward.”

More than 500,000 Texans suffer from some form of dementia, including Alzheimer’s disease, according to Lt. Gov. Dan Patrick.

“With a steadfast commitment, Texas has the potential to become a world leader in combating [dementia] through the search for effective treatments and, ultimately, a cure,” Patrick said.

Funding for education

In the K-12 sector, lawmakers earmarked an extra $195 million for Houston ISD, $126.7 million for Cypress-Fairbanks ISD, $103.1 million for Katy ISD, $80.6 million for Fort Bend ISD, and $61 million for Aldine ISD, the partnership said.

In higher education, legislators allocated:

$1.17 billion for the University of Houston College of Medicine, University of Texas Health Science Center at Houston, UT MD Anderson Cancer Center, and Baylor College of Medicine.
$922 million for the University of Houston System.
$167 million for Texas Southern University.
$10 million for the Center for Biotechnology at San Jacinto College.

Houston-area company leads Texas businesses on Time's most sustainable list

Spring-based IT company Hewlett Packard Enterprise leads the list of eight Texas businesses that appear in Time magazine’s and data provider Statista’s World’s Most Sustainable Companies list for 2025.

HPE landed at No. 68, earning a score of 74.36 out of 100.

Time and Statista said the ranking highlights corporate responsibility and promotes sustainable practices.

“In an era marked by significant environmental challenges and social inequalities, it is crucial to recognize and reward companies prioritizing sustainability,” according to an article on Time’s website. “By featuring these leading entities, the ranking sets a benchmark for other businesses, fostering transparency and accountability and encouraging the integration of sustainability into core corporate strategies.”

Time and Statista’s ranking process started with a list of more than 5,000 of the world’s largest, most influential companies based on factors such as revenue and public prominence. They identified the top 500 companies based on more than 20 data points.

The process weeded out non-sustainable businesses, such as those involved in producing fossil fuels, and zeroed in on:

External sustainability ratings
Availability and quality of sustainability reports
Performance regarding environmental and social responsibility measures

HPE is targeting net-zero status across its supply chain by 2040. Working toward that goal, the company predicts its carbon emissions will decrease by 33 percent from 2020 to 2028.

“The climate transition demands collective action across our entire value chain, and I am resolute in my commitment to ensure that HPE plays a central role in showcasing the attainability of net-zero emissions through our technologies and actions,” said Antonio Neri, HPE’s president and CEO.

Among the ways HPE is reducing carbon emissions are:

Shipping certain products in bigger bundles
Incorporating environmentally responsible design
Using more renewable energy
Improving energy efficiency in buildings
Eventually shifting to an all-electric automotive fleet

Here’s a rundown of the eight Texas-based companies that made the sustainability list, including their global rankings and scores.

No. 68 Spring-based Hewlett Packard Enterprise. Score: 74.36
No. 81 Dallas-based CBRE. Score: 73.49
No. 142 Dallas-based AMN Healthcare Services. Score: 69.8
