Scorching Texas Heat Shows Up in Electricity Consumption

It is not secret that this has been a brutally hot summer and that the ERCOT (Texas) electric grid has been challenged to provide electricity at peak times of day.

What is most shocking though is the huge month-to-month increase in consumption.

Data from the U.S. Energy Information Administration data for ERCOT showed a huge 18% increase between the month of August 2022 and the same month in 2023.?

ERCOT had the highest August electricity consumption in its history, 18% higher than August of 2022. Data from Energy Information Administration.

The largest possible reason for this is air conditioning load. Not only is the air conditioning working longer, but it is operating less efficiently at higher temperatures.

The National Oceanic and Atmospheric Administration released its August statistics for Texas on September 11. The Cooling Degree Days (CDD is a benchmark measurement for weather-related heat and discomfort), increased 23% from August of 2022. Since 1895, the only other August that rivaled this was during the blistering Texas drought of 2011. Even then, it was a negligible 2 CDD days higher.

The state's population increased only 1.6% between 2022 and 2023. However, population skyrocketed 17% between 2011 and 2022.

Austin (Travis County), where I live, actually had the highest August CDD in its history this year. It increased 20% between August of 2022 and August of 2023. Its CDD slightly exceeded the former record set in 2011.

This bodes ill for electric bills.? Austin Energy's recent cost increases plus record consumption in ERCOT could mean Austinites will see record-high electric bills (in nominal dollars).

While I do understand the point of this post, one thing that information above should be defined as "in recorded history" as for much of the Earth's geological record, the AVERAGE surface temperature was 6-10C higher than even the "hottest summer on record" of the current Holocene Epoch (past 100K years). Interestingly, the entire Holocene Epoch has been a period of the lowest temperatures in the Earth's entire 4B year history. Looking at the entire Mesozoic Era and the entire Tertiary Period, temperatures and the number of CDD days were very much lower. In fact, it's possible that during the entire Mesozoic period, there were many years that had ZERO CDD days. It is a very good likelihood, that the Earth is simply returning to its average climate (75% of its existence without ice caps). In addition, prior to the 1960s, including many very hot years past 150 years temperature record, humans lived without air conditioning without any issues. I go to Mexico all the time with areas as hot or hotter than Austin, and in most places that I stay there is not air conditioning. Obviously, folks in Texas don't want to live without AC, but a very fundamental conversation about perhaps being comfortable in 80-85F is warranted.

The increase in consumption doesn't shock me at all, Paul. Everything I've heard from Austinites and other Texas residents all summer is how very hot and DRY it's been. Without meaningful and FAST action to counter current trends in climate change -- and scientists now say "the window is closing" for such change -- it's just gonna get worse as our species faces self-inflicted extinction. Very few human efforts to alter the environment, "control" the weather, or adopt artificial methods of survival in harsh climates have done any good for the environment. We've shaped the current crisis with choices we continue to make on s daily basis.

Excellent use of graphs, and do they ever tell the story! Thanks for a terrific article. We had additional insulation added to the attic of our 12-year-old house, and it kept our bills at the same level as they were before, but not everyone has an energy-efficient home in the first place, much less the ability to add to it. I don’t know how Texans can cope with this without major government help.

The citizens of Texas need to find common ground to stop this insanity. It is especially difficult when it is too hot to breathe! I know that the Yahoo majority at the Texas Legislature this past session was complaining about renewables; but if not for renewables, ERCOT's goose would have been even more cooked.
