Yes, when batteries are discharging at this scale, it’s arbitrage. Responding to frequency events needs batteries to be fast, but it doesn’t usually require a lot of energy.

Mostly because imports/exports can happen at the same time, so if we add those labels, it would be net imports/net exports. Net exports would overlap with actual fuel types, which makes the charts messier than necessary. Instead of adding net import/export labels, we include that data in the text.
