It means you charge the batteries when you have extra power (like a sunny day), and you use that charge to handle the times you don't.

Hm, so that seems to kind of obscure how that power actually got generated. Maybe it was all coal, although that seems unlikely. It seems like battery usage is important to measure. But calling it generation seems to obscure something, unless they're double-counting the generation. That's misleading in another way though.

It's not coal.

Here's the chart with everything but battery+solar turned off.

Makes the scenario quite clear. No double counting.
