This is not correct. Because the Texas grid is isolated, the frequency is not synced with the two other major grids and cannot import electricity at any meaningful capacity. (See http://fnetpublic.utk.edu/frequencymap.html ) Frequency conversion is a costly and difficult to scale problem. If Texas was part of the Western grid they could be drawing excess hydroelectric power from the pacific northwest right now for ex…

Nothing I said in my comment is incorrect. Texas has 5 different connections with the other grids and can import/export through them. But they are irrelevant right now because the other grids do not have enough spare capacity to send to Texas. >If Texas was part of the Western grid they could be drawing excess hydroelectric power from the pacific northwest right now for example. Texas also could have contributed to h…

You do still need generation closer to Texas that works, but as a whole the grid can balance the generation and output a bit depending on the gradient between the sources.

Imagine a 'bouncy castle' with several input fans. Texas is like an entry ramp that isn't hooked up to either of two big banks of fans and sinks next to it. If it were just ganged in with one of those other two groups even though Texas is having a bad time the other blowers could compensate in aggregate.

Did the utility companies ask for voluntary reduction in power consumption ahead of time? We had a situation here where extreme weather and a natural gas pumping station that exploded caused real problems in our natural gas supply. The utility asked everyone to lower their consumption by turning their heat down to 65. Luckily, that was the extent of the rationing.

My companies office volunteered to power off so we got to all work from our homes. That was only good for those of us still with power, though.

I'm just surprised every time I hear of someone working in an office!

Afaik, the way abnormal situations like these are handled in northern Europe is that the grid suppliers have agreements with the very large industrial consumers (think aluminium smelters) who agree to shut down immediately when the grid frequency goes below a certain trigger level. The way I understand it, this is useful both in time-critical emergencies (like keeping the grid at 50 Hz when a nuclear plant suddenly g…

Isn't it immensely difficult to restart an aluminum smelter? Also, my vague memory of these is that in North America most of them are in areas with abundant hydro power.

Maybe having more nuclear power plants instead of wind would have helped? It sounds unrealistic for the energy generators to sell electricity at a loss over a 10 year period. It would be nice to see some of the data that the professor is referring to.

The article clearly states that many natural gas plants were knocked out due to the cold. So why aren't you asking "maybe having more nuclear instead of natural gas would have helped?" Since nuclear uses water, which freezes, the reason why the gas plants were knocked out, maybe the problem isn't the power source itself but the lack of weatherization?!

> Since nuclear uses water, which freezes

I suspect that the water involved in the steam generation (heavy water or otherwise) wouldn't freeze since it's inside/near the core, and constantly temperature regulated.

The water used for cooling would go through heat exchanging and would also not freeze, especially if it's underground, or deep in a lake somewhere.

> If your house is 25f, put on a couple sweaters and a coat and have a beer. It’s not the end of the world. Houses were designed very differently 150 years ago. Lower roofs, fewer windows, huge thick drapes or tapestries on the walls, animal skins or carpets on the floors. 9 ft windows (double pane or not) on all walls is going to leak out a lot of heat. Most importantly, fireplaces. Houses had fireplaces, and rooms…

You clearly haven't been in many 150 year old West Texas houses. Good lord... The spread of AC in the 1930s resulted in everything in Texas being insulated out the wazoo. Your typical suburban home in Texas -- with no electricity -- is perfectly habitable without power. Its an inconvenience, to be sure. But, all this handwringing over a freak -- and fun -- event is laughable. Want to fret? Fret about floods, tornadoe…

You obviously don’t live anywhere near texas. No houses have insulation for this kind of weather.

It’s like if I went to Canada and started shitting on people unable to deal with 110f weather without electricity .

Not much discussion here of the fundamental problem: why is Texas so energy intensive? In the last decade ERCOT energy generation has expanded 20%, which is much faster than the population of Texas has grown. Why? Just gigantic, detached houses for everybody? I think this is why people say the California housing crisis is such a calamity for the environment. A person in Texas consumes 150% more energy.

Wow, that surprised me. Current demand is 45GW in Texas vs. 24GW in California. Over double per capita.

A social political decline is what happened and continues to happen. When California encountered power issues, it was easier for Texas politicians (and many of their followers) to espouse malicious soundbites about Commifornia than to empathize, offer support and self reflect on what lessons can be learned and applied locally. Now that Texas is reaping its own fruits of decades of anti-"other side" politics and polit…

What can we, private citizens with entrepreneurial skill and talent, do to combat this partisan schadenfreude?

Get rid of party primaries and move to ranked choice, approval, or straight ranked voting, like Alaska did.

Increased A/C adoption? I mean, presumably the same thing is happening in other areas of the Southwest (nobody's ripping out their air conditioners and throwing them away, and some are installing new ones). The reductions in per-capita electricity consumption in CA must be made up by great efficiency increases, since no doubt A/C usage is going up at the same time. OTOH, if power was as cheap at is in Texas, perhaps investing in efficiency wouldn't be worth it.

Also, it sounds like Texas' population has increased by 3.8 million to 29 million from 2010 to 2020. That sounds like pretty darn close to 20%.
