According to the article I read it is something that happens every 8-10 years. It's been a known issue for almost 30 years. With the increasing frequency of the polar vortex, it will probably be occurring more often. It may be worse with the increasing dependence on electricity from the grid.

I don't think they would spend the money for a once in 50 years storm vs. just shutting them down for a week. Maintenance would be a pita to keep clear.

Probably a huge balance issue too. I would think they would have a deice sprayer on the tower or some such thing. If they can deice an aircraft prior to departure I would thing they could make a weeping wing type of thing on the blade.I used to fly a C-210 that was certified for flight in known ice. We had heated prop and windshield as well as a glycol system the bled it onto the wings, prop and windshield. Back up alternator too. Still, I didn’t ever use it that much. I always avoided those colored areas on the nextrad.

Just like aircraft wings, iced up blades don't provide lift and, if they do, it can be turbulent, going in and out of stalled conditions, which can break the blades, bearings, etc. So shut down until above freezing conditions shed the ice.

so, are the turbines actually frozen, like iced over and cant break loose, or is the lubricant frozen? I dont understand how something with that much mechanical force can be frozen. Here i think the cutoff is 20-25mph in winds IIRC, is it too windy for them to run?On Tue, Feb 16, 2021 at 10:28 AM Bill Prince <part15...@gmail.com> wrote:
--Some of the explanation. Gas and coal plants have never been updated to handle periods of cold, so until they are updated, this will continue to happen.

That'll show the major transmission lines and how they do or don't interconnect.
The EIA also has an interactive map that lets you zoom in.
It also seems like Texas may need more than two nuclear plants.

Subject: [AFMUG] Power outages
El Paso Electric which serves our area and Southern New Mexico is not part of the other Texas utilities experiencing rolling power outages. Back in 2011 we had power outages and water pipe damage. Both utilities took steps to prove systems with anti-freeze technology and all types of sensors.We installed several sensors and links for many of these projects years ago.As of 6:00pm today only 3,000 customers lost power for five minutes.Hope you guys are safe.
