Even a much more modest goal of provisioning a single day of storage would entail 11.5TWh of storage. Dozens of 100 MWh facilities is still in the single digit GWh range. That's six orders of magnitude. And this isn't even taking into account handling heating, industrial use, and all the other forms of tapping into fossil fuel energy besides electricity.

10TWh / 1 GWh = 10^4

Where on earth is six orders of magnitude coming from? You’re off by a factor of a hundred.

Global daily electricity consumption is 60TWh per day. And that's only Electricity consumption. Total energy consumption is more than 100TWh per day. The duration of storage to fulfill 100% of this demand with renewables varies depending on energy mix, long distance transmission, and more but is usually in the range of at least one day's worth of storage.

The point is that dozens of 100MWh stations is basically nothing. You'd need millions of these sites to make renewables a feasible primary source of energy. Our current technology is not sufficient to make energy storage available to make grid storage viable.

Yes a dozen 100GWh facilities is 1.2 GWh, and that's an order of magnitude less in difference, I don't doubt your ability to multiple by factors of ten.
