AI could strain Texas power grid this summer


Texas is no stranger to power-grid anxiety. Between the heat that’s only getting hotter, an aging fleet of power plants, and the challenges of integrating renewable energy, the system is fragile.

Now, a boom in energy-hungry computer data centers is adding a new element of risk this summer.

“How many are coming? That’s still TBD, but we know that they are explosively growing,” ERCOT CEO Pablo Vegas, told lawmakers in one of two hearings this month at the state capitol.

Vegas said many of those centers mine crypto currency. But more and more of them are being built to support artificial intelligence systems. They are drawn to the state thanks to low energy costs, minimal regulation and a booming economy. But they use a lot of energy.

“If you do a google search and just look up ‘What is ERCOT?’ If you did that with a regular google system versus an AI google search, the amount of energy that it takes to run the AI search, is between 10 and 30 times the power requirement than to do a traditional google search,” Vegas said.

Many estimates you find online appear to be on the lower end of that spectrum. But it’s clear that Texas, in particular, could find that growing energy demand challenging.

Ever since a deadly blackout in 2021, state officials have worked to strengthen the power grid. They’ve started programs to subsidize new power plants and improve transmission lines.

But, those things take years to build. Data centers — some that use as much energy as small cities — can be built in just a matter of months. That is a serious challenge for grid operators, says Doug Lewin, who publishes the Texas Energy and Power Newsletter.

“How do we build enough infrastructure to accommodate a new city popping up in six months, with effectively no notice?” he asks.

The answer: maybe you don’t.

State officials have long declared Texas “open for business” and celebrated in new opportunities, including the construction of this Samsung semiconductor plant in Taylor.

‘The most worrisome thing’

State officials have long declared Texas “open for business.” Reveling in each victory as they lured things like Tesla’s new gigafactory and Samsung’s new microchip plant to the state.

But now, some wonder whether data centers are worth it.

Cryptomines and data centers “produce very few jobs compared to the incredible demands they place on our grid,” Lt. Governor Dan Patrick posted on X, formerly known as Twitter, after the hearings. “Texans will ultimately pay the price.”

State lawmakers, likewise, peppered this month’s hearings with questions about whether the state could put the brakes on data center growth, or compel the companies to pay for their increased energy transmission needs.

“That’s sort of wild to think about,” Lewin said. “That’s a huge, huge break from the way things have been done.”

Assuming that cryptomines and data centers are here to stay, grid operators say they would like new rules to allow them to better monitor the facilities’ energy use and potentially control it.

Despite recent legislation compelling cryptomines to register with ERCOT, Vegas told members of the House State Affairs Committee that about half of companies still have not.

“On legislation […] what would be more helpful for ERCOT is to have more visibility to what these large loads are doing,” he said. “And so a good place to start could be making sure we can track and even potentially control the [energy] loads of cryptos.”

At a recent ERCOT board of directors meeting, Dan Woodfin, the group’s vice president of system operations, said the inability to forecast energy use by crypto mines and similar big power consumers was “the most worrisome thing” going into this summer.

ERCOT puts the chance of rolling blackouts at around 12% in August.

Demand is outpacing supply

In the electricity business, what Vegas proposes — reducing energy use by certain users at certain times — is often called a “demand side” solution to grid challenges.

The idea is that you can strengthen the grid more cheaply and quickly by lowering energy consumption rather than increasing supply.

“We cannot build the grid fast enough to keep up with demand… Even before we had every damned crypto and data center … move to Texas,” Alison Silverstein, a consultant and former state and federal energy official, told KUT. 

Texas currently consumes more energy than any other state. Silverstein has long advocated for increasing energy efficiency standards in the state to help bolster the energy system.

A recent study from the American Council for an Energy Efficient Economy says improving efficiency standards in Texas would be a more economical way of reducing high energy demand in the summer and winter to strengthen the grid.

Silverstein says it would not only mean people need less power to cool their homes, run their appliances and do business, it would also go a long way toward keeping the lights on.

But lawmakers and regulators have traditionally balked at improving efficiency in Texas, a state known for producing energy not conserving it.

Silverstein says that may be changing, as the challenges of rapidly increasing energy demand become clearer to those in charge of the Texas power system.

At one recent hearing ERCOT’s Vegas referred to efficiency and demand response as an essential tool in keeping the Texas grid stable.

Silverstein says the question is whether that rhetoric will turn into state policy.

“That’s when we’ll know that they really mean it in terms of demand-side solutions, and it’s not just hand waving,” she says.

A total lunar eclipse will turn the moon blood red on Tuesday

A total lunar eclipse will turn the moon blood red on Tuesday


A blood-red moon will soon grace the skies for a total lunar eclipse — and there won’t be another until late 2028.

The spectacle will be visible Tuesday morning from North America, Central America and the western part of South America. Australia and eastern Asia can catch it Tuesday night. Partial stages of the eclipse with small bites taken out of the moon can be seen from Central Asia and much of South America. Africa and Europe will be shut out.

Solar and lunar eclipses happen due to a precise alignment of the sun, moon and Earth. There are between four and seven a year, according to NASA.

The eclipses tend to follow each other, taking advantage of the sweet spot in the celestial bodies’ orbits. Tuesday’s total eclipse of the moon comes two weeks after a ‘ring of fire’ solar eclipse that dazzled people and penguins in Antarctica.

During a total lunar eclipse, the Earth is between the sun and full moon, casting a shadow that covers the moon. The so-called blood moon looks red because of stray bits of sunlight filtering through Earth’s atmosphere.

The show unfolds over several hours, with totality lasting about an hour.

Compared to a solar eclipse, “the lunar eclipse is a little more of a relaxed pace,” said Catherine Miller at Middlebury College’s Mittelman Observatory.

For those in the path, there’s no need for any special equipment to observe — just a clear, cloudless view of the sky.

Use a forecasting app or any online celestial calendar to look up the exact timing for your area. Venture outside a few times to see Earth’s shadow darken the moon, eventually revealing the reddish-orange orb.

“You don’t have to be out there the whole time to see the shadows moving,” said astronomer Bennett Maruca with the University of Delaware.

There’s a partial lunar eclipse on the docket for August, visible across the Americas, Europe, Africa and west Asia.

While most people are looking forward to seeing the eclipse, throughout history — many people saw eclipses as omens of doom. Some superstitions and fears still exist. NBC 5 producer Sara Sanchez learned more from historians and eclipse experts.

Austin Animal Services Hosts Free Spay/Neuter Clinic


Austin Animal Services is hosting a free, high-quality, high-volume spay/neuter for cats and dogs now through March 2 in North Austin.

The five-day clinic, which is being held in partnership with Greater Good Charities, is taking place at 11580 Stonehollow Dr., Suite 160. Registration and drop-off begin on-site each day from 7:30-10 a.m. or until capacity is reached.

In addition to free spay/neuter surgeries, pets receiving surgery will also receive vaccinations, flea and tick prevention, and microchips, ensuring that they return home healthier and better protected.

Spaying and neutering is the most effective tool in preventing unplanned litters and reducing the number of stray and surrendered animals entering local shelters. Managing overpopulation helps individual owners and also strengthens community health by reducing roaming animals, easing shelter overcrowding, and decreasing long-term strain on animal welfare resources.

This is the seventh free clinic the city has hosted since 2024. The previous six clinics provided spay/neuter services to more than 6,000 pets. The upcoming clinic is expected to complete approximately 1,200 surgeries in just five days. It is a significant investment in prevention that helps reduce future shelter intake and supports responsible pet ownership across Austin.

High-volume, high-quality spay/neuter clinics offered at no cost are rare, and many pet owners face procedure costs ranging from $75 to several hundred dollars, along with wait times that can stretch for weeks or months. This clinic removes those barriers by providing same-day services at no charge.

“This clinic is about prevention,” said Austin Animal Services Director Monica Dangler. “When we provide accessible spay and neuter services, we’re helping families care for their pets while also reducing strain on shelters like ours and improving safety across our community.”

Why is Austin so warm in February?

Why is Austin so warm in February?


February is typically one of our cooler months in Austin, Texas.

In 2021, a series of ice storms and snow storms caused mass chaos and is a winter storm that Austinites will never forget. Now, instead of worrying about scraping ice off of our cars, we’re grabbing the swimsuits.

Austin is in the midst of one of the warmest February’s in the city’s history. This year’s January cold snap lingered around for Feb. 1, but since then, only two days have been slightly below average. Compare that with 20 days above average, with the rest of this month expected to have temps in the mid to upper 80s.

But how does this compare to our warmest February ever? We don’t have to go back too far to find the hottest February on record in 2017. The average high temp was 76.5 degrees with 12 out of the 28 days spent above 80 degrees.

Other years in the top 5 were 1999, 1976, and 1957 with each year having numerous days above 80 degrees. So far, 2026 has ten. Plus, I’m forecasting 2 more 80 degree days. Should we hold onto this weather pattern, this will be in the top five hottest February’s of all-time.

For some, this heat may be just another day to grab the swimsuit or head outside and work up a sweat, but this has meteorologists sweating for different reasons. We are in a serious drought now.

The latest drought monitor released on Feb. 26, 2026 has 9 of the 13 counties in the CBS Austin viewing area in an “extreme drought,” which is the second worst category of drought conditions.

In the past 190 days, two of those days have had rainfall over 1 inch. Our current streak of 123 days in a row with less than 1 inch in rainfall is one of the longest since 2000.

Combine the heat and the rainless days, and you get a flash drought. Opposite of a flash flood, hot temperatures rapidly dry out the soil and drought conditions can worsen quickly. With the dehydrated vegetation, dry air, and above average temperatures, you’re now looking at dangerous fire weather.

We’ve already had several fires reported across Central Texas in just the past week. The Nebo Mountain Fire in Gillespie County and the Cedar Gulch Fire in Burnet County. With this above average heat and below average precipitation, we are especially vulnerable.

But there is some good news.

The start of March looks to be starting off very warm, but our pattern looks to become a bit more active. Our long-term futurecasts look to be favoring more showers and storms possible for the first few weeks of March.

Remember that we are also getting closer to our severe weather season. So while we do need the rain, we must remain safe in case we get locally high rainfall amounts in these thunderstorms and be mindful of tornadoes and damaging winds.

Hopefully we can see an improvement in this drought and heat, but history is made in different ways every year nowadays. Maybe it’ll be for the right reasons this time around.
