Canadian energy company Enbridge Inc., whose gas transmission and midstream operations are based in Houston, has flipped the switch on its first solar power project in Texas.

The Orange Grove project, about 45 miles west of Corpus Christi, is now generating 130 megawatts of energy that feeds into the grid operated by the Electric Reliability Council of Texas (ERCOT). ERCOT supplies electricity to 90 percent of the state.

Orange Grove features 300,000 solar panels installed on more than 920 acres in Jim Wells County. Construction began in 2024.

Telecom giant AT&T has signed a long-term power purchase agreement with Enbridge to buy energy from Orange Grove at a fixed price. Rather than physically acquiring this power, though, AT&T will receive renewable energy certificates. One renewable energy certificate represents the consumption of one megawatt of grid power from renewable energy sources such as solar and wind.

“Orange Grove is a key part of our commitment to develop, construct, and operate onshore renewable projects across North America,” Matthew Akman, executive vice president of corporate strategy and president of renewable power at Enbridge, said in 2024.

Orange Grove isn’t Enbridge’s only Texas project. Enbridge owns the 110-megawatt Keechi wind farm in Jacksboro, about 60 miles northwest of Fort Worth, and the 249.1-megawatt Chapman Ranch wind farm near Corpus Christi, along with a majority stake in the 203.3-megatt Magic Valley I wind farm near Harlingen. The company’s 815-megawatt Sequoia solar project, east of Abilene, is scheduled to go online in early 2026. Enbridge has signed long-term power purchase agreements with AT&T and Toyota North America for energy produced by Sequoia.

During a recent earnings call, Enbridge President and CEO Greg Ebel said that given the “unprecedented demand for power generation across North America,” driven largely by explosive growth in the data center sector, the company expects to unveil more renewable energy projects.

“The policy landscape for renewables is dynamic,” Ebel said, “but we think we are well-positioned with our portfolio of late-stage (projects).”

Expert shares tips on ways to make solar panels more accessible to Houstonians

guest column

There’s no question that some homeowners feel a twinge of envy when they see solar panels appearing on homes in their neighborhood. The twin benefits of cutting utility costs and participating in renewable energy are alluring to many.

But as those homeowners consider going solar, many never take the plunge because of concerns about affordability, maintenance and uncertainties around qualifying for tax credits and other state and local rebates. For all its appeal, going solar can seem a bit daunting.

But there are more plentiful financing options available to many Texas homeowners that offer accommodating paths for acquiring solar. They also provide solutions to concerns around maintenance and affordability.

Two innovative strategies for switching to solar

Solar energy providers have been working diligently to deliver more convenient pathways for consumers to make the switch. Recently, two new strategies were introduced in Texas: direct, loan-based ownership, and third-party ownership.

Direct system ownership

With this option, homeowners take out a loan to cover the cost of their solar system and its installation. They can then repay that loan over timeframes ranging from five to twenty-five years.

There are varying rates and terms available to accommodate the preferences and goals of individual homeowners. And while manufacturer warranties and installer workmanship warranties have been available to homeowners, it is important to look for companies that offer guarantees for an extended period of time given that most systems can last several decades. For example, Freedom Forever offers a 25-year production guarantee that provides consumers with a measure of comfort around the long-term costs of owning these systems.

Third-party ownership

Another solar financing option involves third-party ownership using a Power Purchase Agreement (PPA) or lease. With a PPA option, a third-party owns the system, and homeowners either agree to buy power at a pre-defined rate per kWh or through a set monthly payment. Homeowners also have the option of leasing the panels for comparable pre-defined rates or monthly payments. (Maybe add one more sentence that explains the difference between PPAs vs lease).

With these two options, the third party insures and maintains the system. This alleviates some of the maintenance and up front cost concerns that have held some back from solar.

Issues to consider before making the switch

Even with the availability of these new options, solar power doesn’t always make sense for everyone. Your personal energy goals and preferences, as well as your tax situation, are important factors to consider when making this decision. Here are some questions folks should ask before making the switch:

  • Would I prefer owning the system outright or relying on a third-party to handle insurance and maintenance?
  • Am I looking for monthly savings now through a PPA or lease or would I prefer the quickest payback and return on investment?
  • Do I have a tax liability that enables me to get a Federal Tax Credit?

The answers to these questions will help you determine which option, if any, makes sense for you. It’s important to remember there is no “best solution for everyone” when considering your options; there’s only the question of what’s right for you.

Other important considerations

Keep in mind that not everyone will qualify for one of the solar options described above. Even in these cases, your state, local utility or a regional credit union may offer alternative financing options that can help you access solar.

Home equity lines of credit may also be a fitting option for some. Dsireusa.org is an excellent resource to help you investigate what incentives and programs are available in your area.

Final tips

As with any important financial decision, it’s a homeowner’s’ responsibility to practice due diligence in terms of assessing what they can afford and who they buy from. Here are some recommended best practices:

  1. Always get several quotes from various companies.
  2. Ask about production guarantees and warranties.
  3. Ask about the need of a service panel upgrade at the start.
  4. Verify that the company you choose offers products that will work with your home construction and roof.
  5. Prioritize solar providers with an extensive list of authorized dealers, such as Freedom Forever.
  6. Confirm that your prospective solar partner has purchasing options around loans and financing and can help you identify the option that best suits your needs.

The good news is that more homeowners than ever before can now feel more comfortable moving to solar. The new options described above for financing and maintenance can make that switch considerably less daunting than it seemed only a few years ago.

Houston geothermal company picks up power purchase agreement in California

heating up

Houston-based Fervo Energy, a provider of geothermal power, has signed up one of the country’s largest utilities as a new customer.

Under two 15-year deals, Southern California Edison has agreed to buy a total of 320 megawatts of geothermal power from Fervo. Financial terms weren’t disclosed. The power will be enough to deliver electricity to the equivalent of 350,000 homes.

Southern California Edison, based in Rosemead, California, serves about 15 million people throughout a 50,000-square-mile area in California.

The utility will purchase the power from Fervo’s 400-megawatt Cape Station plant, which is under construction in southwest Utah. The plant’s first phase, providing 70 megawatts of power, is expected to be online by 2026.

“This announcement is another milestone in California’s commitment to clean zero-carbon electricity,” David Hochschild, chair of the California Energy Commission, says in a news release.

“Enhanced geothermal systems complement our abundant wind and solar resources by providing critical base load when those sources are limited,” he adds. “This is key to ensuring reliability as we continue to transition away from fossil fuels.”

In June, Fervo announced it would supply 115 megawatts of geothermal power for Google’s two data centers in Nevada. Two years ago, Fervo signed a deal with energy aggregators in California to supply 53 megawatts of geothermal power from Cape Station.

“As electrification increases and climate change burdens already fragile infrastructure, geothermal will only play a bigger role in U.S. power markets,” says Dawn Owens, Fervo's head of development and commercial markets.

Rice research team's study keeps CO2-to-fuel devices running 50 times longer

new findings

In a new study published in the journal Science, a team of Rice University researchers shared findings on how acid bubbles can improve the stability of electrochemical devices that convert carbon dioxide into useful fuels and chemicals.

The team led by Rice associate professor Hoatian Wang addressed an issue in the performance and stability of CO2 reduction systems. The gas flow channels in the systems often clog due to salt buildup, reducing efficiency and causing the devices to fail prematurely after about 80 hours of operation.

“Salt precipitation blocks CO2 transport and floods the gas diffusion electrode, which leads to performance failure,” Wang said in a news release. “This typically happens within a few hundred hours, which is far from commercial viability.”

By using an acid-humidified CO2 technique, the team was able to extend the operational life of a CO2 reduction system more than 50-fold, demonstrating more than 4,500 hours of stable operation in a scaled-up reactor.

The Rice team made a simple swap with a significant impact. Instead of using water to humidify the CO2 gas input into the reactor, the team bubbled the gas through an acid solution such as hydrochloric, formic or acetic acid. This process made more soluble salt formations that did not crystallize or block the channels.

The process has major implications for an emerging green technology known as electrochemical CO2 reduction, or CO2RR, that transforms climate-warming CO2 into products like carbon monoxide, ethylene, or alcohols. The products can be further refined into fuels or feedstocks.

“Using the traditional method of water-humidified CO2 could lead to salt formation in the cathode gas flow channels,” Shaoyun Hao, postdoctoral research associate in chemical and biomolecular engineering at Rice and co-first author, explained in the news release. “We hypothesized — and confirmed — that acid vapor could dissolve the salt and convert the low solubility KHCO3 into salt with higher solubility, thus shifting the solubility balance just enough to avoid clogging without affecting catalyst performance.”

The Rice team believes the work can lead to more scalable CO2 electrolyzers, which is vital if the technology is to be deployed at industrial scales as part of carbon capture and utilization strategies. Since the approach itself is relatively simple, it could lead to a more cost-effective and efficient solution. It also worked well with multiple catalyst types, including zinc oxide, copper oxide and bismuth oxide, which are allo used to target different CO2RR products.

“Our method addresses a long-standing obstacle with a low-cost, easily implementable solution,” Ahmad Elgazzar, co-first author and graduate student in chemical and biomolecular engineering at Rice, added in the release. “It’s a step toward making carbon utilization technologies more commercially viable and more sustainable.”

A team led by Wang and in collaboration with researchers from the University of Houston also shared findings on salt precipitation buildup and CO2RR in a recent edition of the journal Nature Energy. Read more here.
