Texas’ electrical grid requires continuous improvement as technology and weather evolve



This op-ed is part of a series published by The Dallas Morning News Opinion section to explore ideas and policies for strengthening electric reliability. Find the full series here: Keeping the Lights On.

The winter power outage of 2021 cost lives, caused hardship and taxed Texas resources. Now we’re in a summer that has already produced record heat in the Pacific Northwest. Texans could face a summer power failure on the heels of the winter failure.

New laws have just been adopted to avoid failure again. But is the problem solved? Not yet.

With both the electric grid technology and the weather changing, today’s fixes are OK for today, but more will be needed.

The Legislature took a good first step. Lawmakers ignored pundits who filled the airwaves with theories about major flaws. They focused on the problem that occurred by mandating enhanced weatherization to reduce failure in extreme weather.

Now we need to shift our attention to the Public Utility Commission of Texas. We count on it to do the day-to-day parenting of the system.

The June scare about power shortages shows the importance of the commission. It can get to the root cause so the problem can be fixed.

We have to fix things ourselves because those who do not pay the bills can always suggest more spending. For example, the U.S. Energy Information Administration in June predicted the lowest summer electricity consumption nationally since 2009. Last summer, Texas had a cushion of electricity generation capability of 12.9% and no serious problems. This year, that cushion has increased to 15.3%. But the Energy Information Administration listed Texas at an elevated risk because the summer heat might be much worse than anticipated. But it did not suggest what a good cushion might be — it comments but doesn’t help.

Pundits are advocating for even greater changes. The most common include market restructuring and more electrical ties to neighboring states.

Years ago, the Texas Legislature established a market structure to implement the state’s regulatory goals. It worked. But the record cold highlighted some shortcomings. Consequently, continuous improvement is more appropriate than restructuring. The PUC should stimulate further analysis and propose additional incremental improvements.

To many, Texas’ independent grid implies vulnerability. The Texas grid has worked well because, first, Texas is the largest producer and user of energy in the U.S. Second, the combination of the top five Texas cities has a larger population than 35 states. So, the Texas geographical size, population and energy production make it the most likely state to succeed with its own grid.

Increasingly cost-effective small generators can power a house, a neighborhood or a critical load like a hospital or fire station. So, towns can decide whether it is more cost-effective to provide critical buildings with backup power than to strengthen the entire grid.

If all critical loads had their own backups during February’s winter storm, short-term rolling blackouts still could have occurred. But for those with backup, the short-term blackouts would have been insignificant.

As we electrify more vehicles, more of us will have convenient backup power in our driveways. These changes require the PUC to take a broad view of the changing technical environment, meaning the commission needs to develop computer-based planning models of the Texas grid to predict the pros and cons of the emerging technologies and use the results to tweak the market structure so Texas gets lower-cost reliable electricity.

Texas does not have to guess what will happen if it uses a well-designed model to avoid problems.

As voters, we need to continue parenting the political system. Our politically structured power system can adapt to the changing electric grid technology and weather. Success requires that access to affordable reliable energy remains a political priority. And that is up to us.
