Lazard's levelised cost of storage has utility scal Li at $250/MWh round trip to amortise it over it's life...fill it for free, and you need 25c/Kwh when you extract from it.

Utility scale storage has a long way to go.

Specifically, the Tesla battery is sitting there full(ish), and sniping at the frequency control market. They are paid not to cycle to arbitrage power.

edit...if it doesn't trigger your gag reflex at the flipflopping that this agency does in espousing the virtue of the battery...

It's hilarious how that article is worded to suggest that the battery is making money and not whoever owns it or runs it.

What would you expect from a website called reneweconomy? Of course they're going to be biased. They try to make it sound like the Tesla battery is powering the whole system, instead of providing seconds or minutes of energy to trim grid stability during transients.

No, that's not the case...all connected generators are to ride out a certain even for a certain period of time...e..g. under frequency of 47.5Hz (IIRC) for 5 minutes, then you have the right to trip to protect the machine.

These machines, the one in question and subject to the regulatory action did not stay in when they were required to...it wasn't that they were going to be destroyed, they had to ride through the system events for long enough that protection systems would have blacked out sections of the state...they didn't and took the state out with it.

The regulator has ascertained that they "abandoned ship" early, forcing a blackout when they should have (per their contract to the market) stayed safely in service unles the contracted system controls were inadequate.


Ah ok....begs the question as to what the shutdown standards were for the turbines, and if it matched the regulations. I'm sure they should have been the same, but gov't being what it is ...

Paging OVERKILL...please post the graph how Yallour lost a unit and before it had finished tripping the Tesla Battery stepped up to full capacity...

What, that little sliver of yellow at the bottom that was maybe 5 MW? Shouldn't it have ramped up to 100 MW in milliseconds?
