The Oroville Dam is the highest in the nation.
I just thought it was amusing that the barges in the photo at #1450
said “Poseidon” on the sides...
I hadn't noticed that. LOL
“... Of the six units, three can pump water or generate power...”
-
What do you suppose that means?
I thought that there were only 3 units. Regardless, if they can pump or generate, it means that at night when demand is low, they can theoretically run electric pumps to pump water back up into the reservoir. That provides more stored energy for daytime peaks, and evens out the nighttime load as well..
Look up pumped storage plants. We have one nearby called Raccoon Mountain. There are several around the country.
It was announced when this whole episode started,....the generating hall is under water.
Yes, I understand pumped storage, there is a huge one near here.
If that is what they are trying to say, then
the description they give in the caption is poorly written.
Yes, odd use of wording. As if they were trying to impress the masses without actually saying anything.
I’m going to study on that generating facility a bit.

The National Weather Service has issued a flood warning for the area beginning Sunday evening. The general warning covers many counties throughout Northern California and is expected to continue through Thursday.
“Interior Northern California will experience another significant uptick in flooding problems starting late Sunday night and continuing through Monday night as an intense atmospheric river type storm arrives,” the NWS said.
Winds are predicted to be 22-25 mph during the day, with gusts up to 38 mph, easing slightly during the night. Monday is more rain, and heavy at times.
Because the soil is already saturated, and snow will melt, “additional stress will be placed on levees, rivers, creeks, and streams.”
Revisiting the power plant, there are, in fact 6 generating units there, 3 of which are also able to pump water back up to the reservoir. The 3 generator-only units are 132 MW each, while the 3 generator/pumps are capable of generating at 141 MW. I’m not sure of the electrical load they present when pumping, but based on other pumped storage units, it’s probably similar to their generating capacity.
The plant, as a whole, can pass almost 17,000 cfs when all units are generating, and in pumping mode, can pump about 5600 cfs total between the 3 pumps.
I was surprised to see this facility having pumping capability.

About one of the guys who got fired for posting on social media. Pic of the main spillway at link.
yesterday at the bottom of the spillway
notice the big black rocks are now brown to the right where it was splitting....might explain the brown water

This is what the #OrovilleDam spillway looks like on Sunday. Water output has been decreased and the damage & erosion is more visible. pic.twitter.com/LBXzSC7HGs

Here’s a video of the #OrovilleDam. Water output reduced to 55,000 cfs. Most of the water is not flowing down the #OrovilleSpillway.
