SQL File: why are some parameters not present in ComponentSizes

I've got a fully autosized model and I'm looking at the outputs.

For a pump, ComponentSizes has Rated Flow Rate (m3/s) and Rated Power Consumption (W) which makes a ton of sense to me.

For a fan, either one of Fan:ConstantVolume, Fan:VariableVolume or Fan:OnOff, there's only Design Size Maximum Flow Rate (m3/s). Why isn't the Rated Power not present in the ComponentSizes table? Am I missing something or some logic?

Note that this data (and more) is present in the TabularDataWithStrings for ReportName = 'Equipment Summary' (that ends up in the HTML output), but I'd rather avoid grepping values from multiple locations and I don't understand the logic behind it.
