>when it comes to stabilising the grid, those disadvantages are irrelevant.

Run that by me again? The stabilizing happens by charging/discharging those batteries. If you discharge the whole capacity of the battery, it will not stabilize anything. So how do you reckon that the capacity is irrelevant to grid stabilization?

Also to claim that cost is irrelevant to anything, ever, is just the dumbest thing. Cost is the ever present all important enabler. If the battery is not economically viable, it wont be there to stabilize the grid in the first place.

I am talking about voltage stabilization lol.

First off, you should have said so then. Second, why are you talking about Voltage stabilization when the frequency stability is the more pressing issue? Finally Voltage stability is tied to electricity demand/production just like frequency stability. The way you stabilize both the frequency nad Voltage on the gird level is by controlling the generation.

Unless you are talking about Voltage stability at local levels of end consumers. Which again, why would you do that? Then it is question of the actual wires.

Do you even know what you are talking about?

> KVARs

I am talking about it because OP was talking about KVARs.

Now next time read the whole thread if you are missing context.

VAR is a unit of reactive power as opposed to Apparent and Real power. You want to limit the reactive power as much as you can during transmission, to minimize natural loses.

How should I know that when you replied to somebody else who did not talk about reactive power. But alright, while this topic is not very important, you are still wrong on the price. Which is not a big deal, but just so its clear.

Jesus, time wasted because you couldnt provide simple information. You could have cleared this misunderstanding right away.

a) you inserted yourself into the conversation without knowing the context.

b) you need a much smaller battery for reactive power than powering the grid for hours on end.

Stop wasting your own time lol.
