What type of storage is going to offsett a 800 GW peak demand for 2-4 hrs ?billvon said:

No, Solar is not the reason for the pm peak !... There has always been a "late afternoon" peak ...4-8pm , .Punx0r said:
Solar has simply made it more apparent by reducing the daytime demand on the grid.
.. But either way,..you still have to supply that pm demand...and solar cannot do it !
Typical time / demand "curve ..CA.

My pleasure....
...now, would you like to answer the question ?

Hillhater said:25 real GW per year of solar doesnt look to impressive compared to the 90 GW (780 TWh) of increase in electricity demand in 2017 !
..and you just know what is generating the other 65GW ??..... mostly fossils
Unfortunately Despite our best efforts, Solar and Wind build out is not even keeping up with growth. And this is just considering total electricity. Which is only a small fraction of world total primary energy consumption. On a chart of total energy, solar and wind is barely visible at 3%. We still get twice as much energy from burning sticks for heat and cooking. The real solution is to figure out how we can enter a de-growth economy that is content with much lower energy demands.

"The kingdom is considering building 17.6 gigawatts (GW) of nuclear capacity by 2032, the equivalent of about 17 reactors, making it one of the biggest projects globally.
According to Reuters news agency, Saudi Arabia is aiming to reduce the amount of crude it burns at home to generate electricity to allow it to sell more of it overseas.
If the kingdom proceeds with the plan, it would become the second Gulf Arab state to launch a nuclear power project after the United Arab Emirates, which is building four South Korea-designed reactors"

It will be interesting to see which reactor design they choose. It could save the AP1000 if they choose to go that way. They will have a lot of challenges in terms of dissipating all that heat, unless they build close to the ocean.sendler2112 said:

Confirming the fact that the "peak" is still 4-6+ pm, ...cricketo said:
But why do you suggest 1999 gives a better picture of CA electricity use ?.
What we really need to see is the picture for 2029+

So, a virtual private battery?
Battry storage in general are not economical for a grid, unless there is over-generation. But if there is, then growth of PV is less of an issue with these babies

And dramaticaly changed its demand curve !cricketo said:Hillhater said:
You have an Internet equivalent of what's called "selective hearing."
Btw, California added another 6-7 million people since 1999.
...so why bother refering to it ?

Slow progress from Moltex.

London, 13th July 2018
Just weeks after its success in being selected as a winner in the UK government’s Advanced Modular Reactors competition, Moltex is delighted to announce that it has also been selected by New Brunswick Energy Solutions Corporation and New Brunswick Power to progress development of its SSR-W (Stable Salt Reactor - Wasteburner) technology in New Brunswick, with the aim of deploying its first SSR-W at the Point Lepreau nuclear reactor site before 2030.

DOE awards $400,000 for R&D with Argonne
ThorCon US has been awarded $400,000 for cost-shared research and development for advanced nuclear technologies, U.S. Secretary of Energy Rick Perry announced.
ThorCon US is developing a thermal thorium/uranium molten salt fueled ThorConIsle fission power plant. The approach uses shipyard production to build a complete 500 MWe power plant which is towed to a site and ballasted to the sea bottom. The plant will generate electric power cheaper than coal, after completing testing which begins in 2023.

Unfortunately water cooled reactor cores and pumped cooling ponds need to be superceded with something that is indefinitely passive and walk away safe. There is not enough social investment yet in these new molten salt cooled reactors. The Moltex design shows that you can still have a trackable fuel rod type core along with a passive emergency cooling/ low core pressure, salt coolant. Using a simplified reprocessing of high level waste for fuel economically.
There are several LWR designs that are passively safe; decay heat is taken care of by natural convection with no intervention. The AP1000 comes close. The passive cooling system starts automatically without operator intervention. After that the one task is to keep refilling the (exterior) water pond.sendler2112 said:
The APR1400 is a more conventional design, and requires pumps to be powered for months after the core is shut down.

My October utility bill just arrived, and I cracked 5 digits in credits, 10,273 KWH's in the bank. November is typically when my production falls behind my consumption. So all winter I will use up part of my credits, and part of this will be coal fired Wyoming coal, as my utilities hydro output also drops off a bit. I don't lose any sleep how this pencils out, the partial winter time coal versus the other 9 months of wind, PV and micro hydro, all I know is it works for me. I do know I don't dread the utilities bill when it arrives in the mail, instead, I look forward to it.

How does micro hydro work out at your place ? I was looking into it in Oregon, the amount of red tape is ridiculous - I can build a 600W high head system for just about $500, but to get the permit there is $500 initial filing, then $500 upon approval. Then also annual fees based on theoretical HPs, but 10HP min (600W = 0.8HP).
