Research from the Federal Reserve Bank of Dallas shows that solar power and battery storage capacity helped stabilize Texas’ electric grid last summer.

Between June 1 and Aug. 31, solar power met nearly 25 percent of midday electricity demand within the Electric Reliability Council of Texas (ERCOT) power grid. Rising solar and battery output in ERCOT assisted Texans during a summer of triple-digit heat and record load demands, but the report fears that the state’s power load will be “pushed to its limits” soon.

The report examined how the grid performed during more demanding hours. At peak times, between 11 a.m. and 2 p.m. in the summer of 2024, solar output averaged nearly 17,000 megawatts compared with 12,000 megawatts during those hours in the previous year. Between 6 p.m. and 9 p.m., discharge from battery facilities averaged 714 megawatts in 2024 after averaging 238 megawatts for those hours in 2023. Solar and battery output have continued to grow since then, according to the report.

“Batteries made a meaningful contribution to what those shoulder periods look like and how much scarcity we get into during these peak events,” ERCOT CEO Pablo Vegas said at a board of directors conference call.

Increases in capacity from solar and battery-storage power in 2024 also eclipsed those of 2023. In 2023 ECOT added 4,570 megawatts of solar, compared to adding nearly 9,700 megawatts in 2024. Growth in battery storage capacity also increased from about 1,500 megawatts added in 2023 to more than 4,000 megawatts added in 2024. Natural gas capacity also saw increases while wind capacity dropped by about 50 percent.

Texas’ installation of utility-scale solar surpassed California’s in the spring of last year, and jumped from 1,900 megawatts in 2019 to over 20,000 megawatts in 2024 with solar meeting about 50 percent of Texas' peak power demand during some days.

While the numbers are encouraging, the report states that there could be future challenges, as more generating capacity will be required due to data center construction and broader electrification trends. The development of generating more capacity will rely on multiple factors like price signals and market conditions that invite more baseload and dispatchable generating capacity, which includes longer-duration batteries, and investment in power purchase agreements and other power arrangements by large-scale consumers, according to the report.

Additionally, peak demand during winter freezes presents challenges not seen in the summer. For example, in colder months, peak electricity demand often occurs in the early morning before solar energy is available, and it predicts that current battery storage may be insufficient to meet the demand. The analysis indicated a 50% chance of rolling outages during a cold snap similar to December 2022 and an 80% chance if conditions mirror the February 2021 deep freeze at the grid’s current state.

The report also claimed that ERCOT’s energy-only market design and new incentive structures, such as the Texas Energy Fund, do not appear to be enough to meet the predicted future magnitude and speed of load growth.

Houston clean energy storage facility goes online to power ERCOT grid

green light

A new battery energy storage facility in Houston is officially up and running to power the ERCOT grid with a supply of reliable, zero emissions power.

Jupiter Power announced the commercial operations launch of its 400-megawatt-hour battery facility, Callisto I, in central Houston on the site of the former HL&P H.O. Clarke fossil fuel power plant.

"Jupiter couldn't be prouder about bringing the Callisto I project online," Andy Bowman, CEO of Jupiter Power, says in a news release. "This project responds to lawmakers' calls to increase affordable and dispatchable new generation in an area where people need more power. Callisto I is the first energy storage project at this scale in the City of Houston and will help meet Houston's growing power needs while also increasing resiliency from extreme weather events."

The new project is Jupiter Power's ninth project to deliver energy storage to ERCOT — bringing its total ERCOT fleet to 1,375-megawatt-hour capacity — but its the first in the Houston area. The company is currently developing over 11,000 megawatts of projects across the country. Founded in 2017, Jupiter Power is headquartered in Austin and has offices in Houston and Chicago.

"The announcement of Jupiter Power's Callisto I Energy Storage project is significant and exciting for the region, as it's the first large-scale transmission-connected energy storage project in the City of Houston," Jane Stricker, senior vice president at the Greater Houston Partnership and executive director at the Houston Energy Transition Initiative, adds. "This critical project will help address peak power demand and is another great example of our region's leadership in scaling and deploying impactful solutions for an all the above energy future."

Among the company's financial backers is Houston-based EnCap Energy Transition, which invested in Jupiter Power via its Fund II.

Google to invest $1B in clean energy, data center tech in Texas

money moves

Google is making a big investment in Texas to the tune of $1 billion.

According to a news release from the company, the tech giant will spend more than $1 billion to support its cloud and data center infrastructure and expand its commitment to clean energy.

The $1 billion will be spent on data center campuses in Midlothian and Red Oak to help meet growing demand for Google Cloud, AI innovations, and other digital products and services such as Search, Maps, and Workspace.

In addition to its data center investment, Google has also forged long-term power purchase agreements with Houston-based Engie, as well as Madrid-based entities Elawan, Grupo Cobra, and X-ELIO for solar energy based in Texas. Together, these new agreements are expected to provide 375 MW of carbon-free energy capacity, which will help support Google’s operations in Texas.

These agreements were facilitated through LEAP (LevelTen Energy’s Accelerated Process), which was co-developed by Google and LevelTen Energy to make sourcing and executing clean energy PPAs more efficient, and contributes to the company’s ambitious 2030 goal to run on 24/7 carbon-free energy on every grid where it operates.

The company has contracted with energy partners to bring more than 2,800 megawatts (MW) of new wind and solar projects to the state. Google’s CFE percentage in the ERCOT grid region, which powers its Texas data centers, nearly doubled from 41 percent in 2022 to 79 percent in 2023.

The initiatives were announced at a conference in Midlothian on August 15, attended by business leaders and politicians including U.S. Congressman Jake Ellzey, Google Cloud VP Yolande Piazza, Ted Cruz, and Citi CIO Shadman Zafar.

The Dallas cloud region is part of Google Cloud's global network of 40 regions that delivers services to large enterprises, startups, and public sector organizations.

In a statement, Piazza said that "expanding our cloud and data center infrastructure in Midlothian and Red Oak reflects our confidence in the state's ability to lead in the digital economy."

Data centers are the engines behind the growing digital economy. Google has helped train more than 1 million residents in digital skills through partnerships with 590 local organizations, including public libraries, chambers of commerce, and community colleges.

In addition to its cloud region and Midlothian data center, Google has offices in Austin, Dallas, and Houston. The new Google’s total investment in Texas to more than $2.7 billion.

Op-Ed: To protect the Texas grid, help Texans protect themselves

guest column

On the evening of May 16, a devastating “derecho” storm howled through Houston. Nearly 800,000 customers lost power. Many were still without electricity days later, as a heat wave baked neighborhoods that couldn’t power air conditioners.

It was yet another unwelcome reminder about the precariousness of the power grid.

These outages followed repeated grid warnings, conservation calls, and near-misses last summer and the summer before, as well as the catastrophic Winter Storm Uri freeze in February 2021.

The outages also preceded the increasingly extreme weather Texas faces and staggering growth on the ERCOT grid: after growing about 1 percent a year for 20 years, the power grid covering most of Texas may need to be 78 percent bigger by 2030.

So, this latest incident is more than a sign that Houstonians must take control of their power. It also shows that more and more, the state needs you to act.

Like any other market, a power grid runs on supply and demand. The supply of Texas energy is growing, which is great. At the same time, the economy is booming, leaving Texas setting demand records almost constantly. Generators can’t always keep up, especially when power plants break down or don’t produce electricity — there’s about an 18 percent chance that Texas will face at least one grid emergency this summer.

With odds like that, it’s no wonder that more and more Texans are finding ways to live more powerfully. Many are investing in solar panels and energy storage devices like Tesla Powerwalls.

These systems let families and business owners generate electricity during the day, store it, and use it later when there’s an emergency or just when power is scarce. They protect people from high bills and blackouts; it’s no coincidence that just since last month's storm, we've seen a five-fold increase in leads, reflecting a huge growth in interest in solar power. Further, since the storm, 90 percent of new Houston-area solar customers have bought backup battery systems, compared to 50 percent in 2024 and less than 25 percent in 2023.

That pattern has repeated across the country after severe weather events.

Homeowners and business owners can also slash their bills by weatherizing houses and buildings, the way power plants did after Uri. Advanced devices that help people automatically, and voluntarily, reduce electricity use when the grid is stretched would also help.

These improvements and investments would help more than just homeowners and business owners — they’d help the entire power grid. Every kilowatt that someone doesn’t need or can generate themselves frees up power for other families and businesses across the grid. That helps Texas keep the lights on, especially if electricity demand is about to spike as dramatically as the state expects.

Texas already incentivizes conservation and generation at a large scale. For example, large users like manufacturers and crypto miners get paid by ERCOT for reducing electricity use when the grid is stretched. And just last year, the legislature passed a $10 billion program to help fund new gas power plants.

It’s past time to extend similar incentives to everyday Texans, especially when we’re increasingly called upon to help ERCOT keep the lights on.

If crypto companies get money for reducing electricity use when ERCOT asks them to, then residential and business customers deserve to get paid too. The state could help Texans invest in technologies and smart metering programs that cut bills andautomatically reward people for reducing use on the hottest afternoons and coldest mornings.

More than that, the state has got to do more to reward solar customers who generate electricity and return it to the grid when demand rises. These virtual power plants will increasingly provide vital power when the state badly needs it, and consumers need to be rewarded for it. (Fortunately, the state is looking at strategies to take better advantage of virtual power plants.)

Finally, if Texas is helping big generators build gas plants, it should figure out ways to help regular Texans install solar panels and battery storage units. Such systems obviously help protect Texans from power outages, but they also fortify the ERCOT grid by reducing the demand on it.

Last month’s derecho was exactly the sort of freak occurrence that will become more common as the weather grows more extreme. The best way to protect the grid from such catastrophes is to protect individual Texas customers as well.

Houston energy storage company forms $10M partnership to enhance storage in ERCOT region

teaming up

A Houston-based company that's developing long-duration energy storage solutions announced a $10 million investment and partnership with a Texas corporation.

Quidnet Energy has entered into a strategic partnership with Hunt Energy Network, an affiliate of Dallas-based Hunt Energy that develops and operates distributed energy resources. The two Texas companies will work on a build-transfer program for 300 MW of storage projects that uses Quidnet's Geomechanical Energy Storage technology in the Electric Reliability Council of Texas (ERCOT) grid operating region.

“Hunt Energy Network brings an extensive and proven track record across diverse energy businesses, making them an ideal partner to address the need for large-scale, long-duration energy storage in Texas,” Joe Zhou, CEO of Quidnet Energy, says in a news release. “We’re thrilled to have them as an investor, partner, and board member, and we look forward to jointly advancing the deployment of energy storage solutions, particularly in regions like ERCOT where the need is most pressing.”

Todd Benson, the chief innovation officer of Hunt Energy, will join Quidnet's board of directors as a part of the partnership.

“Quidnet Energy's GES technology presents a unique opportunity to revolutionize energy storage, and we’re excited to invest in a solution that purposefully transforms existing resources to expand access to long-duration storage,” adds Pat Wood, III, CEO of HEN. “ERCOT's growing supply of renewable energy makes this region ideal for the deployment of our technology, and we’re pleased to work with another Texas innovator to build a more resilient grid for all ERCOT customers.”

Quidnet’s technology, which can provide over 10 hours of storage, uses drilling and hydropower machinery to store renewable energy. Essentially, the company, founded in 2013, is using water storage to power carbon-free electric grid approach to energy.

One year ago, Quidnet secured $10 million from the U.S. Department of Energy Advanced Research Projects Agency-Energy, or ARPA-E. Just a few months after that, the company received an additional $2 million from the DOE for its project, entitled "Energy Storage Systems for Overpressure Environments," which is taking place in East Texas.

Baker Hughes launches major clean energy initiatives with U.S. military and more

clean team

Energy tech company Baker Hughes announced two major clean energy initiatives this month.

The Houston-based company has teamed up with Dallas-based Frontier Infrastructure to develop carbon capture and storage (CCS), power generation and data center operations in the U.S.

Baker Hughes will supply technology for Frontier’s nearly 100,000-acre CCS hub in Wyoming, which will provide open-access CO2 storage for manufacturers and ethanol producers, as well as future Frontier projects. Frontier has already begun drilling activities at the Wyoming site.

“Baker Hughes is committed to delivering innovative solutions that support increasing energy demand, in part driven by the rapid adoption of AI, while ensuring we continue to enable the decarbonization of the industry,” says Lorenzo Simonelli, chairman and CEO of Baker Hughes.

Additionally, Baker Hughes announced this week that it was selected by the U.S. Air Force and the Department of Defense’s Chief Digital and Artificial Intelligence Office (CDAO) to develop utility-scale geothermal power plants that would power global U.S. military bases.

Baker Hughes was granted an "awardable," or eligible, status through the CDAO's Tradewinds Solutions Marketplace, which aims to accelerate "mission-critical technologies," including AI, machine learning and resilient energy technologies. The potential geothermal plants would provide cost-effective electricity, even during a grid outage.

“The ability of geothermal to provide reliable, secure baseload power makes it an ideal addition to America’s energy mix,” Ajit Menon, vice president of geothermal, oilfield services and equipment at Baker Hughes, said in a news release. “Baker Hughes has been a pioneer in this field for more than 40 years and our unique subsurface-to-surface expertise and advanced technology across the geothermal value chain will help the U.S. military unlock this critical domestic energy source, while simultaneously driving economic growth and energy independence.”

Houston researcher dives into accessibility of public EV charging stations

EV equity

A Rice University professor wants to redraw the map for the placement of electric vehicle charging stations to level the playing field for access to EV power sources.

Xinwu Qian, assistant professor of civil and environmental engineering at Rice, is leading research to rethink where EV charging stations should be installed so that they’re convenient for all motorists going about their day-to-day activities.

“Charging an electric vehicle isn’t just about plugging it in and waiting — it takes 30 minutes to an hour even with the fastest charger — therefore, it’s an activity layered with social, economic, and practical implications,” Qian says on Rice’s website. “While we’ve made great strides in EV adoption, the invisible barriers to public charging access remain a significant challenge.”

According to Qian’s research, public charging stations are more commonly located near low-income households, as these residents are less likely to afford or enjoy access to at-home charging. However, these stations are often far from where they conduct everyday activities.

The Rice report explains that, in contrast, public charging stations are geographically farther from affluent suburban areas. However, they often fit more seamlessly into these residents' daily schedules. As a result, low-income communities face an opportunity gap, where public charging may exist in theory but is less practical in reality.

A 2024 study led by Qian analyzed data from over 28,000 public EV charging stations and 5.5 million points across 20 U.S. cities.

“The findings were stark: Income, rather than proximity, was the dominant factor in determining who benefits most from public EV infrastructure,” Qian says.

“Wealthier individuals were more likely to find a charging station at places they frequent, and they also had the flexibility to spend time at those places while charging their vehicles,” he adds. “Meanwhile, lower-income communities struggled to integrate public charging into their routines due to a compounded issue of shorter dwell times and less alignment with daily activities.”

To make matters worse, businesses often target high-income people when they install charging stations, Qian’s research revealed.

“It’s a sad reality,” Qian said. “If we don’t address these systemic issues now, we risk deepening the divide between those who can afford EVs and those who can’t.”

A grant from the National Science Foundation backs Qian’s further research into this subject. He says the public and private sectors must collaborate to address the inequity in access to public charging stations for EVs.
