There is no difference in the overwriting logic between MARKAL/TIMES; this is a GAMS feature. I see only the following logical possibilities:
- The UCs are not identical (for example, one if FX and the other is LO)
- Different years have been specified in the two cases (not controled with the "-0" declaration) and the timeseries are being merged
- The scenario file with BASE constraints is being read after the new one (depends upon the order on the Solve form)
For storage, send a screen shot with one particular technology behaving and misbehaving. Has your model changed since you sent it to me on May 18?
