Texas stands out among other states when it comes to energy production.

Even after mass rolling blackouts during Winter Storm Uri in 2021, the Lone Star State produced more electricity than any other state in 2022. However, it also exemplifies how challenging it can be to ensure grid reliability. The following summer, the state’s grid manager, the Electrical Reliability Council of Texas (ERCOT), experienced ten occasions of record-breaking demand.

A bigger storm is brewing

Electric demand is poised to increase exponentially over the next few years. Grid planners nationwide are doubling their five-year load forecast. Texas predicts it will need to provide nearly double the amount of power within six years. These projections anticipate increasing demand from buildings, transportation, manufacturing, data centers, AI and electrification, underscoring the daunting challenges utilities face in maintaining grid reliability and managing rising demand.

However, Texas can accelerate its journey to becoming a grid reliability success story by taking two impactful steps. First, it could do more to encourage the adoption of distributed energy resources (DERs) like residential solar and battery storage to better balance the prodigious amounts of remote grid-scale renewables that have been deployed over the past decade. More DERs mean more local energy resources that can support the grid, especially local distribution circuits that are prone to storm-related outages. Second, by combining DERs with modern demand-side management programs and technology, utilities can access and leverage these additional resources to help them manage peak demand in real time and avoid blackout scenarios.

Near-term strategies and long-term priorities

Increasing electrical capacity with utility-scale renewable energy and storage projects and making necessary electrical infrastructure updates are critical to meet projected demand. However, these projects are complex, resource-intensive and take years to complete. The need for robust demand-side management is more urgent than ever.

Texas needs rapidly deployable solutions now. That’s where demand-side management comes in. This strategy enables grid operators to keep the lights on by lowering peak demand rather than burning more fossil fuels to meet it or, worse, shutting everything off.

Demand response, a demand-side management program, is vital in balancing the grid by lowering electricity demand through load control devices to ensure grid stability. Programs typically involve residential energy consumers volunteering to let the grid operator reduce their energy consumption at a planned time or when the grid is under peak load, typically in exchange for a credit on their energy bill. ERCOT, for example, implements demand response and rate structure programs to reduce strain on the grid and plans to increase these strategies in the future, especially during the months when extreme weather events are more likely and demand is highest.

The primary solution for meeting peak demand and preventing blackouts is for the utility to turn on expensive, highly polluting, gas-powered “peaker” plants. Unfortunately, there’s a push to add more of these plants to the grid in anticipation of increasing demand. Instead of desperately burning fossil fuels, we should get more out of our existing infrastructure through demand-side management.

Optimizing existing infrastructure

The effectiveness of demand response programs depends in part on energy customers' participation. Despite the financial incentive, customers may be reluctant to participate because they don’t want to relinquish control over their AC. Grid operators also need timely energy usage data from responsive load control technology to plan and react to demand fluctuations. Traditional load control switches don’t provide these benefits.

However, intelligent residential load management technology like smart panels can modernize demand response programs and maximize their effectiveness with real-time data and unprecedented responsiveness. They can encourage customer participation with a less intrusive approach – unlocking the ability for the customer to choose from multiple appliances to enroll. They can also provide notifications for upcoming demand response events, allowing the customer to plan for the event or even opt-out by appliance. In addition to their demand response benefits, smart panels empower homeowners to optimize their home energy and unlock extended runtime for home batteries during a blackout.

Utilities and government should also encourage the adoption of distributed energy resources like rooftop solar and home batteries. These resources can be combined with residential load management technology to drastically increase the effectiveness of demand response programs, granting utilities more grid-stabilizing resources to prevent blackouts.

Solar and storage play a key role

During the ten demand records in the summer of 2023, batteries discharging in the evening helped avoid blackouts, while solar and wind generation covered more than a third of ERCOT's daytime load demand, preventing power price spikes.

Rooftop solar panels generate electricity that can be stored in battery backup systems, providing reliable energy during outages or peak demand. Smart panels extend the runtime of these batteries through automated energy optimization, ensuring critical loads are prioritized and managed efficiently.

Load management technology, like smart panels, enhances the effectiveness of DERs. In rolling blackouts, homeowners with battery storage can rely on smart panels to manage energy use, keeping essential appliances operational and extending stored energy usability. Smart panels allow utilities to effectively manage peak demand, enabling load flexibility and preventing grid overburdening. These technologies and an effective demand response strategy can help Texans optimize the existing energy capacity and infrastructure.

A more resilient energy future

Texas can turn its energy challenges into opportunities by embracing advanced energy management technologies and robust demand-side strategies. Smart panels and distributed energy resources like solar and battery storage offer a promising path to a resilient and efficient grid. As Texans navigate increasing electricity demands and extreme weather events, these innovations provide hope for a future where reliable energy is accessible to all, ensuring grid stability and enhancing the quality of life across the state.

Hobby debuts solar canopy as airport system reaches new sustainability milestone

solar solutions

Houston's William P. Hobby Airport is generating its own clean energy.

Houston Aiports announced that Hobby's red garage is now home to a "solar canopy" that is producing energy at 100 percent capacity to power daily operations. The photovoltaic (PV) solar system generated more than 1.1 gigawatt-hours of electricity in testing, and is expected to produce up to 1 megawatt-hour now that it's operating at full power.

“This project is proof that sustainability can be practical, visible and directly tied to the passenger experience,” Jim Szczesniak, director of aviation for Houston Airports, said in a news release. “Passengers now park under a structure that shields their cars from the Texas sun while generating clean energy that keeps airport operations running efficiently, lowering overall peak demand electrical costs during the day and our carbon footprint. It’s a win for travelers, the city and the planet.”

The project was completed by Texas A&M Engineering Experiment Station (TEES) and CenterPoint Energy. It's part of Houston Airport's efforts to reduce carbon emissions by 40 percent over its 2019 baseline.

In a separate announcement, the airport system also shared that it recently reached Level 3 in the Airports Council International (ACI) Airport Carbon Accreditation program after reducing emissions by 19 percent in three years. This includes reductions at George Bush Intercontinental Airport (IAH), Hobby and Ellington Airport/Houston Spaceport.

The reductions have come from initiatives such as adding electric vehicles to airport fleets, upgrading airfield lighting with LED bulbs, adding smarter power systems to terminals, and improving IAH's central utility plant with more efficient equipment. Additionally, the expansion to Hobby's West Concourse and renovations at IAH Terminal B incorporate cleaner equipment and technology.

According to Houston Airports, from 2019 to 2023:

IAH reduced emissions by 17 percent
Hobby reduced emissions by 32 percent
Ellington Airport reduced emissions by 4 percent

"I see firsthand how vital it is to link infrastructure with sustainability,” Houston City Council Member Twila Carter, chair of the council’s Resilience Committee, said in the release. “Reducing carbon emissions at our airports isn’t just about cleaner travel — it’s about smarter planning, safer communities and building a Houston that can thrive for generations to come.”

Houston Methodist leader on the push for sustainable health care and new local event

Q&A

Every industry can play a role in the energy transition, and Houston Methodist is leading the charge in the health care sector.

Culminating at this week’s inaugural Green ICU Conference, part of Houston Energy and Climate Startup Week, the health care system has spent the last three years taking a closer look at its environmental footprint—and showing other hospital systems and medical organizations how they too can make simple changes to reduce emissions.

The event, held tomorrow, Sept. 17, at TMC Helix Park, will bring together health care professionals, industry leaders, policymakers and innovators to explore solutions for building a more sustainable healthcare system.

In an interview with EnergyCapital, Dr. Faisal N. Masud, medical director of critical care at Houston Methodist and a champion for sustainability efforts across the system, shares the inspiration behind the event and what attendees can expect to take away.

Tell us about how the Green ICU Conference came to be.

Houston Methodist’s inaugural Green ICU conference is about three years in the making. It originated because Houston Methodist recognized the significant impact health care has on sustainability and the lack of similar initiatives in the U.S.

The Center for Critical Care at Houston Methodist launched a sustainability-focused ICU initiative, published a roadmap and became involved in international efforts to develop guidelines that many other organizations now use. Our work led to the creation of the first Green ICU Collaborative in the country, and the Green ICU Conference was established to share best practices and address the global impact of critical care on the environment.

What were some of the biggest takeaways from the collaborative, and how are they represented in this new event?

Through the Green ICU Collaborative, we’ve seen that health care professionals can make a significant impact on sustainability through simple, practical changes, and many solutions can be implemented without major costs or compromising patient care. Additionally, there’s a strong link between environmental stewardship and patient safety and quality. These lessons will be represented in the new Green ICU Conference by showcasing easy-to-adopt best practices, emphasizing the importance of sustainability in daily health care operations, and fostering a sense of shared responsibility among attendees to improve both patient outcomes and environmental impact.

Why are ICUs considered to be such carbon hot spots?

ICUs are considered carbon hot spots because they care for the sickest patients, requiring intensive therapies, numerous medications and a large amount of equipment, such as ventilators and pumps. This makes them the most resource- and energy-intensive areas in a hospital. A single day in the ICU can have a greenhouse gas impact equivalent to driving a car 1,000 kilometers.

The U.S. health care sector is responsible for approximately 8.5 percent of greenhouse gas emissions, and hospitals are the second-most energy-intensive commercial buildings in the country. With the Texas Medical Center being in the heart of Houston, it’s critical that health care organizations play a role in this area.

That’s why the Center for Critical Care launched a system-wide Green ICU Initiative with the Houston Methodist Office of Sustainability to help reduce our carbon impact and waste while continuing to provide unparalleled patient care. Innovation is part of our culture, and that extends into our sustainability efforts. Houston Methodist’s Green ICU initiative is the first-of-its-kind in the U.S.

What efforts has Houston Methodist taken to cut emissions?

The first step to cutting emissions is measuring an organization’s carbon footprint to determine the best path forward. Houston Methodist’s Office of Sustainability has aggregated two years of baseline emissions data pending third-party validation. The hospital has taken several steps to cut emissions, including implementing composting programs, installing solar panels, improving energy utilization and participating in global plastic recycling initiatives. These efforts are part of a broader commitment led by our Office of Sustainability to reduce the hospital’s environmental footprint.

Tell us a little more about the event. Who should attend? What do you expect to be some of the highlights?

The Green ICU Conference, taking place during Houston Energy and Climate Week, is focused on health care sustainability, bringing together health care professionals, engineers, experts and anyone interested in reducing health care’s environmental impact. With participants and speakers from six countries, the conference brings together leading experts who aim to raise awareness, share best practices and offer practical, easy-to-adopt solutions for making health care more sustainable.

Highlights include perspectives from leading voices in health care sustainability, real-world examples of successful sustainability initiatives and opportunities for networking and collaboration. Anyone interested in health care, sustainability,or making a positive impact in their community should consider attending.

And, because of increasing interest, we’ve opened up the opportunity for attendees to join virtually at no cost or in person.

What do you hope attendees take away? What are your major goals for the event?

The main goals of hosting the Green ICU Conference for the first time are to raise awareness about the environmental impact of health care; engage and empower attendees to implement easy, practical sustainability solutions; and foster a sense of shared community and responsibility.

I hope attendees leave the event feeling motivated and equipped to make meaningful changes in their own practices, whether that’s improving patient care, supporting their colleagues, or leaving their organization and environment in a better place for future generations.

Texas House Democrats urge Trump administration to restore $250M solar grant

solar grants

Eight Democratic members of the U.S. House from Texas, including two from Houston, are calling on the Trump administration to restore a nearly $250 million solar energy grant for Texas that’s being slashed by the U.S. Environmental Protection Agency (EPA).

In a letter to Lee Zeldin, head of the EPA, and Russell Vought, director of the federal Office of Management and Budget (OMB), the House members urged the two officials to reinstate the nearly $250 million grant, which was awarded to Texas under the $7 billion Biden-era Solar for All program. The Texas grant was designed to assist 28,000 low-income households in installing solar panels, aiming to reduce their energy bills.

“This administration has improperly withheld billions in congressionally appropriated funding that was intended to benefit everyday Americans,” the letter stated.

The letter claimed that numerous court rulings have determined the EPA cannot repeal already allocated funding.

“Congress made a commitment to families, small businesses, and communities across this country to lower their utility bills and reduce harmful pollution through investments in clean energy. The Solar for All program was part of that commitment, and the EPA’s actions to rescind this funding effectively undermine that congressional intent,” the House members wrote.

The six House members who signed the letter are:

U.S. Rep. Sylvia Garcia of Houston
U.S. Rep. Al Green of Houston
U.S. Rep. Greg Casar of Austin
U.S. Rep. Jasmine Crockett of Dallas
U.S. Rep. Lloyd Doggett of Austin
U.S. Rep. Julie Johnson of Dallas
U.S. Rep. Marc Veasey of Fort Worth

The nearly $250 million grant was awarded last year to the Harris County-led Texas Solar for All Coalition.

In a post on the X social media platform, Zeldin said the recently passed “One Big Beautiful Bill” killed the Greenhouse Gas Reduction Fund, which would have financed the $7 billion Solar for All program.

“The bottom line is this: EPA no longer has the statutory authority to administer the program or the appropriated funds to keep this boondoggle alive,” Zeldin said.
