Why is there a battery category? That does not seem to fit with electricity GENERATION but I may be missing something.
Generation in this instance means power generation to meet consumption demand. Typically withdrawals from storage are counted as a source of supply to meet that demand regardless of the original source of the power in storage.
So either the solar, wind, etc. datapoints are not being stored or they are double counting. It seems very unlikely all these solar, wind, etc. generators are not storing energy.
