still that's forums for you.
The internet is a magnet for the improperly socialized. Then we have the Ingsoc Sheep Herders as well. So many pros and cons. Would be a beautiful thing with more manners and a modicum of privacy.

There is the angle that they are driven to lash out at things they feel threatened by. I get the same thing in trying to discuss Christianity: deranged people of several stripes will jump into the conversation to rail against things they cannot comprehend.

I (and many others) have tried to set up sub forums where preppers and Christians could discuss our lifestyles, and fellowship in relative peace, but it is difficult to get something like that running. I may try again some day.

A forum I'm on created a rule against non religous people from posting on their religious sub forum.

There is a forum dedicated to religion. This forum is not.

Right now the entire South Western portion of the WECC is under the most brutal heat wave the grid has seen in 20 years.
Electrical demand is so high, power stations have postpones planed off-line down times. However, with demand at record high levels there are no reports of system triggers. That means with the exception of isolated power outages in small service blocks, the grid itself is alive and healthy.

With the exception of anticipated storm damages from Cindy, and again the sporadic service block outages, even the eastern interconnect is operating normally.

The Texas interconnect can't be calculated in as they are partially dependent on mexico for a portion of their electricity and that mexico can pull the plug if the wrong tweet gets them mad.
This is a 4 year old post, but the issue of strengthening the connection between the Western, Texas, and Eastern Interconnects seems to loom even more important with the increased popularity of EVs.

The East and the West interconnects have a total of about 950 gigawatts of power-generating capacity together. And they can share a little over one gigawatt of electricity at present. If you could interconnect the three big power systems in North America, they could support each other.

The original reason, I believe, for having three separate grids is phase shift. If you make the runs long enough, you can't keep the ends synchronized. I took a look, recently, and those three grids are more melded than they were 25 years ago, when I first started studying this.

Still, the million dollar question is when should one subnet help a neighbor subnet, and when should they let it fail, to self protect. Hackers could mess that up, so no one knows how much power is flowing into our out of an area, and a CME could induce currents that go beyond the systems ability to compensate. Especially, if they induce ELF currents below 1 HZ, leaving the transformers no choice but to shut down or fry. And I don't know if the transformers have the autonomous (not Net controlled) ability to force a disconnect.
