>I don't see an indication of how much storage they are talking about here
The final figure shows storage at various MW sizes for 4 hours, 8 hours, and 10 hours.
That said, we have almost no information about this bidding process, so we can't read too much into it.
But once you take into account that these are for projects that enter service in 2023, it makes a lot of sense. By then lithium ion batteries will be less than half the cost they are right now.
Vanadium prices have also been skyrocketing, so its likely that vanadium redox flow batteries may reach industrial scales by then, and could be as cheap or cheaper than lithium ion.
