Currently in the definition, only capacity variables are included for CHPs
Added activity variables (secondary energy) for heat and electricity production by CHP type.

This variable structure is not in line with the variables for power generation Secondary Energy|Electricity|{Source}. Is there any centralized heat from combustion that is not from a combined heat-and-power generation plant?

CHPs are currently not member of the |Electricity|{Source} or {Heat Source} category because they produce both heat and electricity. I examined that existing variable list has capacity variables for CHPs (e.g., 'Capacity|Combined Heat and Power|Biomass') (heat_and_power.yaml) and proposed activity variables for electricity and heat for the same. Do you propose to create a CHP category similar |Electricity|{Source} which can be referred to create CHP related variables? For centralized heat (e.g., district heating) not coming from CHPs variable used are similar to this 'Secondary Energy|Heat|Biomass'.
