I forgot to give an explicit answer to this question:
> NCAP_AFC(ACT,DAYNITE)= 0.625 - means that each hour the storage can be charged/discharged with 60 (MW) * 0.625 = 37.5 MW of heat? this also means that over a day (24 hr) up to 37.5 * 24 = 900 MWh can be charged or discharged? Am I understanding this correct?
NO, that is not correct at all. NCAP_AFC(ACT,DAYNITE) defines an availability factor for the activity (ACT). The activity represents the storage level, and so this parameter defines the maximum amount of energy that can be stored at any timeslice. It does NOT define a limit for the amount charged or discharged. The bounds for the amount charged or discharged are defined by the availability factors for the input / output flows (NCAP_AFC(NRG,DAYNITE)).
