Thank you for the example Antti. We will now change the way of modelling electrolysis in a denser manner than previously. In this example NCAP_OLIFE = 10, and I assume this is the lifetime of a plan...

Dear Antti, LCOE works fine in a stochastic model now. I am not sure what was the issue earlier. I apologies for using your time.

Dear Antti, thank you for your investigation. This is good news. I also have a colleague that successfully reported LCOE in a stochastic run in another model. I will test reporting LCOE again ...

Post: Reporting LCOE in stochastic models

I have experienced that it is not possible to report LCOE/ Var_NcapR for stochastic model runs. Is this correct? If yes, will it be possible in the future? Pernille

It is the same issue with the life time of electrolysis and batteries. Personally, I address this in a simplified manner, by including several processes, of example PEMs, with different model input on...
