Which batteries are these ?

We don't have any grid sized batteries specifically designed to support the grid directly. You are talking rubbish.

We have a handful of small batteries spread around that aren't there for bulk grid support.

That would be like expecting a 1 GW coal fired power station to support the east coast grid by itself.

You are making a fool of yourself with your lack of knowledge.
