Dear Blick, X-Air, and WeatherCat faithful,
Edouard, since you live out there, can you explain how cutting power to relatively limited areas helps lower fire risks?
. . . .
*Sigh* I wish there was a truly rational explanation. The real explanation is legal liability reduction. A number of wildfires have been caused (supposedly) by failures of PG&E equipment. In particular, the Camp fire which burned the town of Paradise was caused when a very high voltage wire supplying power to the entire region broke off the steel tower that supported it. This happened in a very rugged uninhabited area, but the fire spread quickly toward the towns that ultimately were burned.
The inconvenient truth for PG&E was the winds responsible for the failure where hardly extreme by electrical utility standards - no more than around 50 mph (If I recall correctly closer to 35 mph.) If utilities couldn't trust they power lines to withstand that sort of winds in tornado alley, there would be no electricity in those locations. It seems clear that PG&E had been deferring maintenance on these towers and the insulators that would have been able to withstand the winds - failed.
According to the utility, they have been working at a breakneck speed to inspect all their infrastructure and bring up to industry safety standards. However, there is blood in the water and lawyers will clearly pounce on PG&E should this ever happen again. So to avoid an event that would kill the company, they requested and got permission to cut the power off from those high voltage power towers that bring power into urban areas. This is the
"supposed" explanation. However, clearly this sort of thing is leaving everyone very unhappy. Yesterday I saw an amazing sight:
This truck was full of these crates that you can see in close-up on this photo:
These are automatic standby generators that are powered by natural gas and start automatically and immediately if the power it cut off. Here is the product listing for this company:
http://www.generac.com/all-products/generators/home-backup-generators This truck was delivering a generator to house about a mile from ours and it appeared that the company had gotten enough orders to dispatch a truck with these generators just a few days after the power was cut off.
It is a curious move because it really is only suitable for power outages. Bad weather is extremely rare in California and the other looming fear in California is earthquakes. Any earthquake strong enough to take out the bower grid will most likely take out the natural gas system at the same time - making this sort of generator useless. Considering they are expensive and require a complex installation by a professional electrician, this is a very large investment to respond to future potential power shutoffs alone.
Yet, I cannot blame my neighbors either. I have one more picture from yesterday:
This tree was spared last June and was to the right of all these trees cut back then:
Here we are in October and all of a sudden a tree that was "okay" in June now has to be removed. Does this look like an organization that has a coherent fire prevention strategy or more like a
"chicken with its head cut off?"Very sad times indeed here in California, . . . . . . .
Oh well, . . . . . Edouard
