You know the old adage: "If you don't like the weather here, wait five minutes." Texas weather is not just unpredictable; it can be downright bipolar. I don't need to remind you of the knockout punch Old Man Winter delivered last February, even to parts of the state where hard freezes are few and a "snow event" usually amounts to a dusting. It will be a long time before Texans forget spending a week without power in single-digit temperatures — huddled together in their homes under mountains of blankets — with no heat, no way to bathe or cook, and no escape.

The massive power outages of Valentine's Day week spurred public outrage and a full-throated demand that state leaders take decisive steps to make Texas' electric grid sustainable. The legislature was only a month into its 140-day regular session at the time, but still failed to do anything substantial to fix the grid before adjourning May 31.

Now — well ahead of the hottest days of summer — Texans are wondering why the Electric Reliability Council of Texas (ERCOT) is already asking them to set their thermostats at 78 degrees, turn off lights, avoid using their ovens or doing laundry in the evenings, and otherwise conserve energy. It was ERCOT's second such call since April. Some local energy companies have recommended setting thermostats even higher, and local rolling blackouts have continued in Dallas, Houston, and elsewhere in the state throughout the months of June and July. That may be fine for some people during Texas' scorching summer heat, but for others, it is untenable. For the elderly or infirmed, it could be deadly.

Experts have warned the grid is unreliable, the system is strained, and homeowners and businesses hover at near-constant risk for blackouts, unless the state does more to weatherize the grid, bring more generators back online, and provide more emergency backup power. Meanwhile, when temperatures hit triple digits and stay there for days, the blackout risks will skyrocket.

But there is one obvious solution to grid instability that will enable Texans to keep their homes and businesses comfortably cool during the hot summer months ahead, without setting their thermostats higher or timing their activities to government guidelines. Widespread distributed generation of solar energy, instead of the current emphasis on remotely located utility-scale solar, would provide a highly effective, long-term solution to decreasing strain on the ERCOT power grid.

That means dramatically increasing the number of solar installations on residential and commercial properties statewide. Consider the distance and infrastructure required to bring power from a West Texas solar farm to the state's big cities. That's not only a costly undertaking, it exposes the system to many vulnerabilities along the way. It makes more sense to install solar panels on-site, behind the meter, and pair them with storage for backup power.

The logic is simple: Increasing the number of homes and businesses with on-site solar power would decrease the burden on the grid and help insulate it against failure. Further, by installing home batteries such as the Tesla Powerwall for backup power, residents can control their own power supply and ensure its reliability, even during extreme weather events—summer or winter.

These technologies are cost-efficient and readily available today. A few months ago, Congress extended the 26 percent federal solar investment tax credit (ITC) — which also applies to batteries paired with solar — through 2021 (dropping to 22 percent in 2022), making the move to solar and backup power even more sensible.

State leaders have tried to lay the blame for last winter's power outages on renewable energy. But failures of natural gas power plants, not renewable generators, caused the grid failures that led to those deadly blackouts.

On July 6, months after declaring "everything that needed to be done was done to fix the power grid in Texas," Governor Abbott ordered the PUC to take steps to overhaul the state's electric system. But the solutions he's offering—like constructing new coal, gas, and nuclear power plants and building their transmission lines faster—are giveaways to the fossil fuel industry and will take a long time to complete. Texas needs reliable power NOW.

Meanwhile, state officials are increasingly emphasizing conserving power during extreme temperatures, which suggests they don't even believe their assurances that no more blackouts lie ahead. On-site solar power is the obvious solution, both today and for the long-term health of our rapidly growing state and rapidly warming planet.

Expert: Texas must grow its solar infrastructure to prevent more weather-related power outages

guest column

As Texans begin to recover from last month's once-in-a-century winter storm, many wonder how the state — an icon of the oil and gas industry and home to Houston, "the energy capital of the world" — was thrust into darkness for days on end.

When the Texas power grid began failing in communities statewide, many in positions of power quickly laid the blame at the feet of the renewables industry. But with solar and wind power accounting for only 28.6 percent of the state's energy supply, clearly, renewables were not the sole, or even primary, culprits responsible for the massive outages. The facts point to a much more complex set of circumstances — a series of extreme weather events, one after the other; a burgeoning population; and a grossly unprepared system — all of which combined to cause an increasingly strained, aging grid to fail spectacularly.

The events of last month were a not-so-subtle demonstration of the inadequacy of our current power structure, but what does that mean for the future of Texas energy? Obviously, Texas leaders and the Electric Reliability Council of Texas (ERCOT) must begin updating the state's grid with the resources necessary to sustain the rapidly increasing demand for reliable power. Undoubtedly, that will cause a hike in consumer energy costs, especially in deregulated markets like Houston, where profitability and demand drive prices.

Widespread distributed generation of solar energy—rather than the state's current emphasis on utility-scale solar generation — would provide a highly effective, long-term solution to minimizing strain on Texas' power grid. This means dramatically increasing the number of local solar installations on residential and commercial properties statewide. Think about it: The distance and infrastructure required to bring power from West Texas solar farms to the state's urban centers leaves too much room for vulnerabilities. Solar makes more sense on-site, behind the meter, and paired with storage for backup power.

Simply stated, the more businesses and residences who have solar power, the less burden on the grid and the more insulated the grid is against failure. Further, by installing batteries such as the Tesla Powerwall for backup power, solar customers control their own power supply and ensure its reliability, even during extreme weather events like the one we just experienced. These batteries are mass market-ready, reliable and cost-efficient today.

With the increasing volatility of the Texas energy market, home and business owners are finding solar is a more appealing investment than ever before.

The amount of solar power required to power a home or business depends on the amount of energy the owner seeks to offset. For example, a solar array geared toward reducing an energy bill will be significantly smaller than a system designed to take the customer off the grid entirely. Backup power solutions are similarly dependent, with options ranging from a single battery capable of powering small household appliances to a bank of several batteries or a generator able to power a whole household or commercial space. Either way, the combination of solar power and backup provides reliability many Texans wished they had during the record freeze we just endured.

The public outcry over the massive power outages has laid a mandate at the feet of state leaders: Do what is necessary to make the power grid sustainable. At the same time, utilities statewide are looking at what they can do to increase reliability in their own communities. Deregulated energy prices will only rise because of continuing population growth and the need to update grid infrastructure.

No matter how you look at it, enlarging the state's independent solar infrastructure is a reliable way to protect businesses and homeowners alike against surging energy costs and weather-related power outages.

Now is the time for Houstonians to invest in solar energy, says expert

Guest column

Largely due to the growing popularity and falling prices of solar energy in Texas, including incentives at the federal, state, and local level, the number of solar panel installations continues to trend upward throughout the state and especially in Houston.

For the third year in a row, Houston was named the top municipal user of green energy in the nation by the United States EPA, using more than 1 billion kilowatt hours (kWh) of solar and wind power. With 92 percent of the city of Houston's energy coming from green power, solar has solidified its place in the Houston energy market.

With solar panel system prices dropping 38 percent over the past five years, solar power is also growing in popularity among individual homeowners and business owners who want to take control of their energy costs and become more self-sufficient.

As the recent COVID-19 pandemic continues to shake industries across the nation, Freedom Solar is working tirelessly to keep our team safe, healthy, and employed. Solar installers provide critical electric generation infrastructure that helps us reduce the strain on the ERCOT grid, especially with higher electricity usage as people stay at home under local shelter in place orders and as we head into the warmer spring and summer months.

The health and safety of our customers and employees is our top priority, and as an essential business we are following strict operating protocols that are in line with the guidance provided by local, state, and federal authorities. Although these challenging times often result in a pause in investments, I argue that for customers who have been considering investing in solar, now is still the time to do so.

During these tumultuous times, for many home and business owners, investing in solar energy remains appealing as a smart and stable financial decision. A solar power system is an income-producing asset that will generate a stable return for 25 or more years. The ability to finance that investment without putting cash down upfront allows customers to get the financial benefits of solar now while keeping their money in the securities markets until they recover from the current economic downturn.

Due to the COVID-19 pandemic, overseas manufacturing has been disrupted for months, resulting in shortages in the global supply chain across many industries. These shortages could increase the price of solar panels, inverters and related equipment if US warehouses run low on inventory. For customers who have long been on the fence about investing in solar, I would urge them to reevaluate the numbers now in anticipation of potential price increases in the coming months in the wake of COVID-19.

Additional macro trends and current events continue to demonstrate the value of home solar power. According to a 2020 study by the financial institution Fundera, the number of regular telecommuting employees has grown by 115% since 2005. As more and more people are required to work remotely, especially during the current and indefinite "Stay in Place" orders, electricity usage and utilities have inevitably increased for many households.

Investing in solar for your home can help offset increased utility costs, especially while working remotely and in the rapidly approaching summer months. Current events may be accelerating the long-term trend, and even when the immediate crisis is over, the way many people work could be transformed.

As the energy industry continues to evolve, the reasons why Houston customers choose to invest in solar power evolve and grow. Going solar is no longer solely a testament to your sustainability practices but also a sound long-term investment. The federal solar tax credit — also known as the investment tax credit (ITC) — allows homeowners and businesses to deduct a significant percentage of the cost of installing solar from their federal income taxes.

The credit remains at 26 percent for the remainder of 2020 but will decrease to 22 percent in 2021 and then in 2022 will drop to 10 percent for businesses and will go away entirely for homeowners. With more than 90 percent of Houston's energy consumption deriving from green power, it is clear that solar is here to stay.

Houston climbs to top 10 spot on North American tech hubs index

tech report

Houston already is the Energy Capital of the World, and now it’s gaining ground as a tech hub.

On Site Selection magazine’s 2026 North American Tech Hub Index, Houston jumped to No. 10 from No. 16 last year. The index relies on data from Site Selection as well as data from CBRE, CompTIA and TeleGeography to rank the continent’s tech hotspots. The index incorporates factors such as internet connectivity, tech talent and facility projects for tech companies.

In 2023, the Greater Houston Partnership noted the region had “begun to receive its due as a prominent emerging tech hub, joining the likes of San Francisco and Austin as a major player in the sector, and as a center of activity for the next generation of innovators and entrepreneurs.”

The Houston-area tech sector employs more than 230,000 people, according to the partnership, and generates an economic impact of $21.2 billion.

Elsewhere in Texas, two other metros fared well on the Site Selection index:

  • Dallas-Fort Worth nabbed the No. 1 spot, up from No. 2 last year.
  • Austin rose from No. 8 last year to No. 7 this year.

San Antonio slid from No. 18 in 2025 to No. 22 in 2026, however.

Two economic development officials in DFW chimed in about the region’s No. 1 ranking on the index:

  • “This ranking affirms what we’ve long seen on the ground — Dallas-Fort Worth is a top-tier technology and innovation center,” said Duane Dankesreiter, senior vice president of research and innovation at the Dallas Regional Chamber. “Our region’s scale, talent base, and diverse strengths … continue to set DFW apart as a national leader.”
  • “Being recognized as the top North American tech hub underscores the strength of the entire Dallas-Fort Worth region as a center of innovation and next-generation technology,” said Robert Allen, president and CEO of the Fort Worth Economic Development Partnership.

While not directly addressing Austin’s Site Selection ranking, Thom Singer, CEO of the Austin Technology Council, recently pondered whether Silicon Hills will grow “into the kind of community that other cities study for the right reasons.”

“Austin tech is not a club. It is not a scene. It is not a hashtag, a happy hour, or any one place or person,” Singer wrote on the council’s blog. “Austin tech is an economic engine and a global brand, built by thousands of people who decided to take a risk, build something, hire others, and be part of a community that is still young enough to reinvent itself.”

South of Austin, Port San Antonio is driving much of that region’s tech activity. Occupied by more than 80 employers, the 1,900-acre tech and innovation campus was home to 18,400 workers in 2024 and created a local economic impact of $7.9 billion, according to a study by Zenith Economics.

“Port San Antonio is a prime example of how innovation and infrastructure come together to strengthen [Texas’] economy, support thousands of good jobs, and keep Texas competitive on the global stage,” said Kelly Hancock, the acting state comptroller.

NRG inks new virtual power plant partnership to meet surging energy demands

Powering Up

Houston-based NRG Energy recently announced a new long-term partnership with San Francisco-based Sunrun that aims to meet Texas’ surging energy demands and accelerate the adoption of home battery storage in Texas. The partnership also aligns with NRG’s goal of developing a 1-gigawatt virtual power plant by connecting thousands of decentralized energy sources by 2035.

Through the partnership, the companies will offer Texas residents home energy solutions that pair Sunrun’s solar-plus-storage systems with optimized rate plans and smart battery programming through Reliant, NRG’s retail electricity provider. As new customers enroll, their stored energy can be aggregated and dispatched to the ERCOT grid, according to a news release.

Additionally, Sunrun and NRG will work to create customer plans that aggregate and dispatch distributed power and provide electricity to Texas’ grid during peak periods.

“Texas is growing fast, and our electricity supply must keep pace,” Brad Bentley, executive vice president and president of NRG Consumer, said in the release. “By teaming up with Sunrun, we’re unlocking a new source of dispatchable, flexible energy while giving customers the opportunity to unlock value from their homes and contribute to a more resilient grid

Participating Reliant customers will be paid for sharing their stored solar energy through the partnership. Sunrun will be compensated for aggregating the stored capacity.

“This partnership demonstrates the scale and strength of Sunrun’s storage and solar distributed power plant assets,” Sunrun CEO Mary Powell added in the release. “We are delivering critical energy infrastructure that gives Texas families affordable, resilient power and builds a reliable, flexible power plant for the grid.”

In December, Reliant also teamed up with San Francisco tech company GoodLeap to bolster residential battery participation and accelerate the growth of NRG’s virtual power plant network in Texas.

In 2024, NRG partnered with California-based Renew Home to distribute hundreds of thousands of VPP-enabled smart thermostats by 2035 to help households manage and lower their energy costs. At the time, the company reported that its 1-gigawatt VPP would be able to provide energy to 200,000 homes during peak demand.
