re: So the mayor of Lake Charles wasn't warned Entergy was about to shut down its power

Does anyone think that SWB or Cantrell wouldn't be given a warning about losing their power grid?
Even if they were given a warning, they'd find a way to frick it up.

I don’t know if many people realize how terrible municipalities are ran in Louisiana.

My mil called us around 8 last night and said there was an announcement that our power may go off but should be restored around midnight. Not sure where she got that news from because I didn’t get any kind of Nola alert message.
That being said, my white bread neighborhood never lost power. It was cold last night, I feel bad for anyone in a raised home that lost electricity.

You would think the city would have enough pumping capacity to refill the water towers - otherwise the water pressure would have been falling all along.
I guess it could just be a question of how long it takes them to refill. I do imagine that all of those dripping faucets add up to a considerable usage increase. Although if they don’t have electricity, they probably aren’t taking showers...
Are they still on generator power? Could also be that they have less pumping capacity on generator power for whatever reason - for example, if they have backup pumps that are driven directly by diesel engines.

well they started this with basically 0 water and are now operating at double peak demand

Did you read anything?
The city was not notified that power was going down so they didn't have personal on site to start the generators. This was an issue with entergy, not the city.

Why are we bending over to blame politicians when this seems to be Entergy's failure to communicate. Also, the power went off in NOLA last night with no advanced notice and it appeared that energy didn't tell anyone until right before it happened.

Hunter said issues with water began after a citywide blackout Tuesday with no advance warning from Entergy that required water plants to switch over to generator power.
It seems like common sense that you would keep the hospital grids up

When we got rolling blackouts in Thibodaux, they sent us messages 2-3hrs after cutting power.

It was almost an hour in some places but it was going to last until 12am. The point was this was an issue with Entergy not communicating.

Ah, I misread your OP.

FWIW, there’s a difference between an emergency load shed and a planned rolling blackout - you can potentially have both in a short period.
Example: A unit at a power plant goes down and the utility has to immediately shed load (cut off some number of customers’ power) because there isn’t enough capacity. Then, they come up with a plan to continue operating at reduced capacity via rolling blackouts. If you were one of the customers who got hit by the initial load shed, this announcement could happen hours after you lost your power.

So I think there is a misconception about how these systems are designed.
Most of the time it's based off the metered usage of the average between 7-9 am and 7-9 pm and then multiplied by a factor. Its not designed to have 100% of population at home with faucets open running.
Same with electrical grid.

And? How often do they know ahead of time that power is going out? Why weren’t the generators setup to automatically swap over? Why weren’t all of the towers/storage kept completely full around the clock during this event to give plenty of time to handle an emergency?
Most of these systems are underfunded and poorly ran and are just a mistake or two from a disaster.

Your water pressure is maintained by the water towers. The pumps just refill the towers. So your water will continue to flow without the pumps being online, but the pressure will drop as the water towers drain (eventually stopping completely if the towers go dry).
It’s normal for the level in water towers to fall during peak demand and rise during low demand. Having to refill empty towers during continuous high demand, possibly with backup pumps, is not normal.

Yeah, that kind of sucks. Waiting for Entergy's response to that.
Just a hunch, but Suddenlink is probably thrilled they aren't being blamed for any of this shite this time.

I don't think that they're automatic and the issue was the time between the power shut off and generators coming on line. If we had been warned, I'm sure that a lot of the prep could have been done so the time lag wouldn't have been nearly as bad. I don't believe that you just turn on generators of this size. All the water drained out of the system in that time lag, and they can't rebuild pressure b/c everyone still has their faucets open (like I said earlier, it's a Tragedy of the Commons situation in real time).
Most times when there are generators in play involving an automatic transfer upon commercial failure, there will be a tertiary source of power involved to cover the transfer period, most often batteries. So say commercial power fails, generator fires up, and it takes 10-20 seconds for the generator to carry the load...there would be a string of batteries in place to carry the load during that 10-20 second transfer.
I find it hard to believe that anytime LC water experiences a commercial power failure, the water system just dies and loses pressure. They must've had a tertiary component that failed.

Yeah, I realize how the systems work. I think the part I’m having difficulty imagining is exactly how much added consumption there is from those dripping faucets. Whenever I drip a faucet during cold weather, I literally turn it down to a drip. The point is to give the water somewhere to go if there’s an expanding ice plug. But the more I think about it, I’m sure there are people that literally turn the faucet on at like 50% and leave it.
