No additional capacities at trade processes (IRE)

[Raulm]

Hey All,

I have a model with 28 regions, with “ELC” trades between them (bi-lateral trade). The ELC exchange between regions is working exactly as it supposed. However, I’m afraid that the trade capacities cannot be increased by the model. There might be some issue that is undermining their expansion. 

I have a “trade links” file, which has all possible links between regions, declared under a matrix approach. Also, I have the “Trade_Parameters” file, which has some trade attributes as follows:

~TFM_INS

TimeSlice   LimType   Attribute      Year        AllRegions   Pset_ Set   Pset_ PN     Pset_CO   Cset_Set   Cset_CN
                                 INVCOST        2010            1500                                 TB*          ELC_HV
                                  VAROM         2010             0.45                                 TB*          ELC_HV
                                   LIFE                                 100                               TB*, TU*
                                COM_IE          2010             0.95                                   TB*          ELC_HV                     ELC_HV


The Parameters file is also used to declare the stock (by different matrices for every ten years until 2050, as the simplified one below, ), which presents the capacity stock (current existing capacity) that remains under operation until 2050.

~TRADE_Param:Stock~2010

           ELC_HV                    N1            N2
             N1                                       3140
             N2                        3140


The trade process capacities never grow for any scenario I am running. And, sometimes, Veda can only find a solution whether I set an infinite stock for some specifics trade processes, otherwise it wouldn’t find a solution. Therefore, if Veda were to increase these trades installed capacities (IRE capacity) it would be certainly enough to find a solution in those cases. 

Any suggestion? Should I somehow declare these trades processes through a Subres file?


Thanks!

I don't see anything here that would prohibit investment in these trade processes. Select only this Process in Browse - TIMES view, and see if it has picked up some unexpected attribute from some other scenario file.

Thanks for your response, Amit.

I'm not finding any other related scenarios that could hinder the trade expansion by browsing these processes. I set all INVCOST and VAROM to zero, but it remains. I will look at other aspects that might be impacting trade investments.

Possibly, VEDA has activated NCAP_BND(UP)=2 for Year=0 by default prohibiting new investment into the technology as you have specified stock. You can override that by specifying NCAP_BND~0=0 for the desired technologies.

Thanks, Partha, this is a good suggestion. 

I had re-imported all files from scratch and it worked! Now Veda is increasing trade capacities for specific scenarios, as supposed. But I have the feeling that your suggestion would work as well.
