Hi,
I am sorry but I may have a simple question:
Does VAR_FOut represent an annual value or the total over a period (e.g., 2033–2037, if 2035 is the milestone year)? I assume it reflects the cumulative amount over that period—am I correct? I'm asking because some attributes, like Cost_INV, are defined on an annual basis, while others are not. Just wanted to confirm this point for clarity.

All flows and activities are reported on an ANNUAL basis for each period (i.e. for one year, the Milestone year), regardless of the timeslice. So, if the timeslice is ANNUAL, it represents the flow in the full Milestone year, and if the timeslice is, for example, an hourly timeslice for a single representative day in June, it is the flow in 30 hours' time (one hour in each day of June of the Milestone year). Summing the flows over timeslices thus gives the aggregated flow over the full year.
I think this is also what users would want, to easily get energy balances like in annual statistics. I am quite surprised that you have expected cumulative amounts over periods to be reported.
This holds for storage activities as well, i.e. VAR_ACT reported for any hour of a single representative day in June would be the sum of the storage level in that hour over 30 days.

Hi Antti,
Thank you. That aligns with my understanding as before. But for the dismantling material out (defined by using NCAP_OCOM; for example, a facility can be decomposed into different material and these are also reported as VAR_Fout). I found these VAR_Fout align with cumulative material mass balance rather than annual material mass balance. For the energy flows defined as ANNUAL then aligning with Annual level balance. I am very confused here.
Best,
Xiao

I just tested with NCAP_OCOM, and I am not able to confirm your findings. I can see VAR_FOut being reported according to the ANNUAL amount of the commodity released during dismantling. So, I am very confused about your statement. Could you produce some evidence supporting it? Maybe a small test model demonstrating your findings?
