Interpretation of Marginals

[Tanzeel]

I am bit confused to interpret the output from 'Marginals-Demand Sectors' table. This is output result from the Pakistan-Integrated Energy Model of residential commodities.

It would be great help for me to support me to grasp the subject of marginals.

Hi Tanzeel,

Good to see you using the VEDA Forum!

The marginals on the Demands indicates what it would add to the Objective function is the demand was 1 unit higher. Often the 1st period or two one needs to ignore the marginals as the model is over constrained. But after that it gives you a good indication of the relative pressure on the system to meet each demand. So for your residential analysis it will show you where perhaps more technology/fuel options may be helpful, or truly which demands are the most difficult to meet.

Hope this helps some.
