Warning: Houston could be in for an especially uncomfortable summer.

A new study from solar energy company Wolf River Electric puts Texas at No. 2 among the states most at risk for power outages this summer. Michigan tops the list.

Wolf River Electric analyzed the number of large-scale outages that left more than 5,000 utility customers, including homes, stores and schools, without summertime electricity from 2019 to 2023. During that period, Texas experienced 7,164 summertime power outages.

Despite Michigan being hit with more summertime outages, Texas led the list of states with the most hours of summertime power outages — an annual average of 35,440. That works out to 1,477 days. “This means power cuts in Texas tend to last longer, making summer especially tough for residents and businesses,” the study says.

The Electric Reliability Council of Texas (ERCOT), which operates the electric grid serving 90 percent of the state, predicts its system will set a monthly record for peak demand this August — 85,759 megawatts. That would exceed the current record of 85,508 megawatts, dating back to August 2023.

In 2025, natural gas will account for 37.7 percent of ERCOT’s summertime power-generating capacity, followed by wind (22.9 percent) and solar (19 percent), according to an ERCOT fact sheet.

This year, ERCOT expects four months to surpass peak demand of 80,000 megawatts:

  • June 2025 — 82,243 megawatts
  • July 2025 — 84,103 megawatts
  • August 2025 — 85,759 megawatts
  • September 2025 — 80,773 megawatts

One megawatt is enough power to serve about 250 residential customers amid peak demand, according to ERCOT. Using that figure, the projected peak of 85,759 megawatts in August would supply enough power to serve more than 21.4 million residential customers in Texas.

Data centers, artificial intelligence and population growth are driving up power demand in Texas, straining the ERCOT grid. In January, ERCOT laid out a nearly $33 billion plan to boost power transmission capabilities in its service area.

ERCOT announces plan to improve Texas power grid reliability

a better grid

Texas Gov. Greg Abbott recently demanded aggressive action from state utility regulators to shore up the power grid.

Now, the Electric Reliability Council of Texas, or ERCOT, is revealing its plan to address improvements.

On Tuesday, July 13, ERCOT released a 60-item roadmap it said will be updated regularly through the end of the year. The council says it includes both existing and new initiatives.

Here are a few of the items, according to ERCOT:

  • Taking a more aggressive approach by bringing more generation online sooner if it's needed to balance supply and demand. The grid operator is also purchasing more reserve power, especially on days when the weather forecast is uncertain.
  • Requiring CEO certifications. After a rule change, all market participants who own or operate generation resources and/or transmission/distribution power lines will be required to submit a letter signed by their CEO twice a year certifying their companies have completed their weatherization preparations to protect the electric grid for the summer and winter seasons.
  • Adding new requirements for generation owners. ERCOT is proposing a new market rule that requires generators to provide operational updates more frequently.
  • Assessing on-site fuel supplies. ERCOT is reviewing the need for on-site fuel supplies for some generators.
  • Performing unannounced testing of generation resources. ERCOT says this testing helps verify that generators have provided accurate information about their availability.
  • Addressing transmission constraints in Rio Grande Valley. ERCOT and the PUC (Public Utility Commission) are initiating a process to address RGV transmission limitations and provide increased market access for resources in the Valley. ERCOT says this will improve reliability for customers during normal conditions and high-risk weather events.


ERCOT and grid woes continue to be top of mind for Texans. At least 220 generators were offline the week of June 14 when council officials called for Texans to conserve power.

Axiom Space-tested cancer drug advances to clinical trials

mission critical

A cancer-fighting drug tested aboard several Axiom Space missions is moving forward to clinical trials.

Rebecsinib, which targets a cancer cloning and immune evasion gene, ADAR1, has received FDA approval to enter clinical trials under active Investigational New Drug (IND) status, according to a news release. The drug was tested aboard Axiom Mission 2 (Ax-2) and Axiom Mission 3 (Ax-3). It was developed by Aspera Biomedicine, led by Dr. Catriona Jamieson, director of the UC San Diego Sanford Stem Cell Institute (SSCI).

The San Diego-based Aspera team and Houston-based Axiom partnered to allow Rebecsinib to be tested in microgravity. Tumors have been shown to grow more rapidly in microgravity and even mimic how aggressive cancers can develop in patients.

“In terms of tumor growth, we see a doubling in growth of these little mini-tumors in just 10 days,” Jamieson explained in the release.

Rebecsinib took part in the patient-derived tumor organoid testing aboard the International Space Station. Similar testing is planned to continue on Axiom Station, the company's commercial space station that's currently under development.

Additionally, the drug will be tested aboard Ax-4 under its active IND status, which was targeted to launch June 25.

“We anticipate that this monumental mission will inform the expanded development of the first ADAR1 inhibitory cancer stem cell targeting drug for a broad array of cancers," Jamieson added.

According to Axiom, the milestone represents the potential for commercial space collaborations.

“We’re proud to work with Aspera Biomedicines and the UC San Diego Sanford Stem Cell Institute, as together we have achieved a historic milestone, and we’re even more excited for what’s to come,” Tejpaul Bhatia, the new CEO of Axiom Space, said in the release. “This is how we crack the code of the space economy – uniting public and private partners to turn microgravity into a launchpad for breakthroughs.”

Chevron enters the lithium market with major Texas land acquisition

to market

Chevron U.S.A., a subsidiary of Houston-based energy company Chevron, has taken its first big step toward establishing a commercial-scale lithium business.

Chevron acquired leaseholds totaling about 125,000 acres in Northeast Texas and southwest Arkansas from TerraVolta Resources and East Texas Natural Resources. The acreage contains a high amount of lithium, which Chevron plans to extract from brines produced from the subsurface.

Lithium-ion batteries are used in an array of technologies, such as smartwatches, e-bikes, pacemakers, and batteries for electric vehicles, according to Chevron. The International Energy Agency estimates lithium demand could grow more than 400 percent by 2040.

“This acquisition represents a strategic investment to support energy manufacturing and expand U.S.-based critical mineral supplies,” Jeff Gustavson, president of Chevron New Energies, said in a news release. “Establishing domestic and resilient lithium supply chains is essential not only to maintaining U.S. energy leadership but also to meeting the growing demand from customers.”

Rania Yacoub, corporate business development manager at Chevron New Energies, said that amid heightening demand, lithium is “one of the world’s most sought-after natural resources.”

“Chevron is looking to help meet that demand and drive U.S. energy competitiveness by sourcing lithium domestically,” Yacoub said.
