Can the Texas grid handle extreme weather conditions across regions?

From raging wildfires to dangerous dust storms and fierce tornadoes, Texans are facing extreme weather conditions at every turn across the state. Recently, thousands in the Texas Panhandle-South Plains lost power as strong winds ranging from 35 to 45 mph with gusts upwards of 65 mph blew through. Meanwhile, many North Texas communities are still reeling from tornadoes, thunderstorms, and damaging winds that occurred earlier this month.

A report from the National Oceanic and Atmospheric Administration found that Texas led the nation with the most billion-dollar weather and climate disasters in 2023, while a report from Texas A&M University researchers indicates Texas will experience twice as many 100-degree days, 30-50% more urban flooding and more intense droughts 15 years from now if present climate trends persist.

With the extreme weather conditions increasing in Texas and nationally, recovering from these disasters will only become harder and costlier. When it comes to examining the grid’s capacity to withstand these volatile changes, we’re past due. As of now, the grid likely isn’t resilient enough to make do, but there is hope.

Where does the grid stand now?

Investment from utility companies have resulted in significant improvements, but ongoing challenges remain, especially as extreme weather events become more frequent. While the immediate fixes have helped improve reliability for the time being, it won't be enough to withstand continuous extreme weather events. Grid resiliency will require ongoing efforts over one-time bandaid approaches.

What can be done?

Transmission and distribution infrastructure improvements must vary geographically because each region of Texas faces a different set of hazards. This makes a one-size-fits-all solution impossible. We’re already seeing planning and investment in various regions, but sweeping action needs to happen responsibly and quickly to protect our power needs.

After investigators determined that the 2024 Smokehouse Creek fire (the largest wildfire in Texas history) was caused by a decayed utility pole breaking, it raised the question of whether the Panhandle should invest more in wrapping poles with fire retardant material or covering wires so they are less likely to spark.

In response, Xcel Energy (the Panhandle’s version of CenterPoint) filed its initial System Resiliency Plan with the Public Utility Commission of Texas, with proposed investments to upgrade and strengthen the electric grid and ensure electricity for about 280,000 homes and businesses in Texas. Tailored to the needs of the Texas Panhandle and South Plains, the $539 million resiliency plan will upgrade equipment’s fire resistance to better stand up to extreme weather and wildfires.

Oncor, whose territories include Dallas-Fort Worth and Midland-Odessa, analyzed more than two decades of weather damage data and the impact on customers to identify the priorities and investments needed across its service area. In response, it proposed investing nearly $3 billion to harden poles, replace old cables, install underground wires, and expand the company's vegetation management program.

What about Houston?

While installing underground wires in a city like Dallas makes for a good investment in grid resiliency, this is not a practical option in the more flood-prone areas of Southeast Texas like Houston. Burying power lines is incredibly expensive, and extended exposure to water from flood surges can still cause damage. Flood surges are also likely to seriously damage substations and transformers. When those components fail, there’s no power to run through the lines, buried or otherwise.

As part of its resiliency plan for the Houston metro area, CenterPoint Energy plans to invest $5.75 billion to strengthen the power grid against extreme weather. It represents the largest single grid resiliency investment in CenterPoint’s history and is currently the most expensive resiliency plan filed by a Texas electric utility. The proposal calls for wooden transmission structures to be replaced with steel or concrete. It aims to replace or strengthen 5,000 wooden distribution poles per year until 2027.

While some of our neighboring regions focus on fire resistance, others must invest heavily in strengthening power lines and replacing wooden poles. These solutions aim to address the same critical and urgent goal: creating a resilient grid that is capable of withstanding the increasingly frequent and severe weather events that Texans are facing.

The immediate problem at hand? These solutions take time, meaning we’re likely to encounter further grid instability in the near future.

Three Houston-based companies—Fervo Energy, Quaise Energy and XGS Energy—have been selected by the U.S. Department of Energy to advance geothermal technologies and field tests.

Combined, the companies will receive more than $45 million in funding from the DOE's Next-Generation Geothermal Field Tests and Geothermal Resource Characterization and Confirmation initiative. The projects were among 21 selected from around the country to receive a total of $99 million.

Fervo was selected to conduct two projects under the initiative for approximately $20 million in funding. For the first project, the geothermal unicorn, which achieved first power at its flagship geothermal plant last week, will drill and complete enhanced geothermal systems (EGS) wells in Elmore County, Idaho, and will deploy high-temperature seismic monitoring technology at record-high temperatures at or above 200°C.

For the second project, the company will conduct an appraisal drilling campaign at a "high-priority" site in Humboldt County, Nevada, to confirm if the reservoir is suitable for EGS development.

“We are grateful to the Department of Energy for funding these grants. We believe this is a clear indication from the federal government that expanding geothermal energy to new states is a national priority,” Jack Norbeck, CTO and co-founder of Fervo Energy, said in a news release. “We expect this funding to accelerate Fervo’s pipeline and advance the cutting edge of geothermal technologies.”

Fresh off a $180 million Series B, Quaise Energy also received $25 million in DOE funding through the initiative to support its Project Obsidian super hot geothermal plant in Central Oregon. The funding will go toward the analysis of the drilling, stimulation and flow results of the first two wells at the Project Obsidian site, which will help the company optimize its third well on site.

“This DOE support is a recognition of what we are building at Quaise and the progress we are making in the field, including the confirmation well currently being drilled at Project Obsidian,” Carlos Araque, CEO and president of Quaise, said in a release. “Our ambition has always been to make superhot geothermal a commercial reality, and Project Obsidian is where we first deliver on that promise.”

XGS Energy, which recently relocated its headquarters from Palo Alto, California, to Houston, was also selected for an exploration drilling project. The company will drill a deep vertical appraisal well in Socorro County, New Mexico, to determine if the site is a viable source of geothermal energy. XGS had not disclosed a funding estimate at press time.

The full value of the proposed DOE funding is subject to completion of award negotiations, according to Quaise.

Data from these projects will be shared through DOE’s Geothermal Data Repository (GDR), providing valuable information to researchers and stakeholders in the geothermal sector.

“This is an excellent example of how public and private entities can partner together to scale critical energy technologies,” Tim Latimer, CEO and co-founder of Fervo, added in a release. “With this funding, the Department of Energy is making important investments to help Americans across the country gain access to clean, affordable geothermal energy.”

Other geothermal companies and institutions from around the country will complete the 17 remaining projects. They include:

  • Denver-based 400C Energy Inc.
  • Salt Lake City-based AlterG Resources
  • Denver-based DAVINCI EP LLC
  • Anchorage-based GeoAlaska LLC
  • Oklahoma City-based GreenFire Energy Inc.
  • Virginia-based Hexagon Energy LLC
  • Virginia-based INTEK Inc.
  • Chicago-based Invenergy Geothermal Development LLC
  • Massachusetts-based LiPower Geothermal LLC
  • Fort Worth-based Oriah Geothermal LLC
  • Reno-based Raser Power Systems LLC
  • Santa Fe-based San Ildefonso Services LLC
  • Salt Lake City-based The University of Utah
  • Reno-based TLS Geothermics Corp.
  • Salt Lake City-based Zanskar Geothermal and Minerals
