TFM_UPD table
#17
AkramS> I thought the model would extrapolate the values for NCAP_COST in 2012 onwards, meaning that the model knows that NCAP_COST in 2050 and 2012 are equal.

Well yes, the "model" (actually TIMES) would extrapolate the values for NCAP_COST in 2012 onwards.  This happens when the TIMES code is executed.  The TIMES code is executed under GAMS, when any model instance is solved.  You are right, TIMES then knows that NCAP_COST in 2050 has the extrapolated value.

AkramS> With this, in the MIG table of the next scenario I could change the value by  using a multiplier. Wrong?

Yes, wrong.  VEDA is not executing the TIMES code, but GAMS. VEDA does not actually know which value NCAP_COST will have in 2050. In principle, VEDA perhaps could also extrapolate the values e.g. during TFM_MIG processing, but as far as I know, such is currently not possible. Instead, you can do it yourself, by specifying source years in the TFM_MIG table, an example below for process EXAMSTD2:
   

In the example above, the MIG table takes the original values defined for 2010 or 2012 as such (they remain unchanged).  And then, for defining the changed NCAP_COST value for 2050 using the values defined in MyScenario:

  ● if the last value defined is for 2010 or 2012, that value is multiplied by 1.5 to get a changed value for 2050,
  ● if the last value defined is for 2020, that value is multiplied by 1.4 to get a changed value for 2050,
  ● if the last value defined is for 2030, that value is multiplied by 1.3 to get a changed value for 2050,
  ● if the last value defined is for 2040, that value is multiplied by 1.2 to get a changed value for 2050.

I tested this, and it seemed to work well, as described above. Again, I am not a VEDA expert, but maybe @Amit could confirm that it is always the last value generated from the MIG table for 2050 that will survive.
