Stationary battery systems now at $51/kWh!
30% lower than a year ago.
(This is the lowest price for a 4 hour battery system in a new large tender in China.)

The problem here is “4 hour battery system”. Yes it’s true batter backup typically can’t last longer than four hours. Remind me how long the wind can be absent and how many hours the sun don’t shine in Canada in winter.
A 4 hour battery means you can (dis)charge it in 4 hours. Not *faster*. But certainly slower. The hours say *nothing* (!) about the length of time without solar or wind you can bridge. Yes I'm sure.
Is that with PCS included? I can not understand how this can be economically sustainable. Dumping of inventory in the market?

extremely low price... I mean, you almost can't get battery cell at that point.
I don't get how anyone can be profitable with these prices.
This is the price a Chinese state owned construction entity bid into a Chinese state owned tender.
Writing that price demoninated in USD is meaningless.
This is where all the smart money is heading.
Grid-scale batteries answer most of the old tired complaints against solar as an energy source.
A 4 hour megapack equipment costs about $1MM for 4,000 kWh so $250/kwh. How are you getting $51/kwh?
Well, that is in China. Not in Europe.
Nuclear is also cheaper per kWh in China compared to Europe: $0.07/kWh.

Is a Noon Energy non-lithium (long duration) battery being piloted, w 2025 commercialization?
Tell me: 1) t development status of ti battery; & 2) its level of energy storage/cost?
What is t cost to protect a hospital in Puerto Rico from a 3-4 day grid outage!
This is the way we need to go, the only way to make this transition work. Battery storage is 
In germany we would need 30 Years to Produce that much Battery to holde a week in Winter and then how do we charge then again??

Question: say I want to get 50MWh batteries onboard a ship. What kind of mass are we talking about?
And yet residential battery prices have been stable for quite a few years.
When are they going to drop ?
Why is it just 4hour? Can you use it for 8 hours (if you double the capacity) ?
When do batteries go to $10?
Do they ever approach $1?
We need at least $10 or lower for TWh scale national multi-day storage
And this is just the beginning...

'The 373MW Cleve Hill solar farm in Kent has entered commercial operations, exporting more than four times as much power as the next largest UK solar project. Construction is also underway on a 150MW co-located battery energy storage system (BESS).

This price drop in batteries sparks hope for widespread clean energy! MENA's energy landscape can shift swiftly with such advancements, paving the way for sustainable growth. Exciting times ahead!

Nice! That would mean: Investment required 1800E9 $ to cover 30 days of #Dunkelflaute in Germany which is equal to 36 TWh storage capacity acording to this article. That is 2.5 times the amount Germany already did investin RE. With poor result.

Read this article, and comment considering.
1. Ind. Energy consptn density in D is high.
2. D is not CA (PV)
3. Overbuilt not an option in D
4. 36 TWh @ €100/KWh storage makes a poor CF for ca.30 days
5. D:500 bn € in RE: now ~400g/kWh. x.com/QvistStaffan/s
