You should read about base load energy production to understand what's going on here.

Look, this is Texas. It's not about base load energy production. This is a system that--several times this past year--is running at demand around 100% of supply capacity. That shouldn't happen; it's just bad industrial engineering.

The cryptocurrency mines aren't adding base load here. It's adding more load on a system that's already taxed to its limits, and justifying it as a good thing because "oh, we can get paid to turn it off if there's too much demand." People should be yelling at ERCOT for being an incompetent regulator that's letting the grid get away with too little supply (and that's what this article is sort of doing, except its anger is directed towards cryptocurrency mines, not ERCOT, so it's somewhat misplaced).

And, for what it's worth, cryptocurrency is kind of bad at base load. It's not using any reactive power.

  • Reactive power is by definition unused.

    A constant stream of demand that does not fluctuate and can be turned off at a moment's notice without any dire consequences, that's bad at base load? How so?

    These heat waves and extreme cold events are purportedly unprecedented, due to climate change. Should we be surprised when electricity infrastructure designed for normal times gets strained? I've been in countries with rolling power outages, I wouldn't call the Texas grid badly engineered. Considering it's a standalone grid I'd say it's got to be fantastically engineered to have the uptime that it has, I don't think the UK even has such a resilient system.

      Tell that to someone from the UK, and they're likely to laugh in your face. The UK has never faced rolling power outages; Texas faced that just two years ago (although ERCOT appears to have had some issues with the "rolling" part). Furthermore, I don't think the UK has ever had to go voluntary load-shedding measures; Texas had to do that several times this past month, and last summer, etc.

      It's hard to say that the extreme cold event was uprecedented when the exact same thing happened in Texas but a decade prior, complete with learnings that would have prevented the breakdown of the grid (i.e., rolling blackouts) had they been implemented. And the extreme heat wave has been impacting, well, more or less the entire world, and most of the power systems haven't even had to suggest that customers use less power. This is stuff that is eminently predictable, and in most of the world, electricity capacity is planned under the basis of extreme demand scenarios, not normal demand scenarios. If Texas's grid is designed merely for normal demand, then that is a surprise that should have Texans up in arms about the incompetence of their electricity regulator.
