Hi,
first post on the forum. I have a few questions about different potential methods for simulating economies of scale for a technology.
1) Is it possible to assign a fixed cost to a technology (i.e. an absolute value $X million dollars) irrespective of capacity rather than a cost that is proportional to capacity ($X million per PJ capacity)?
2) Is there a way to set or enforce a minimum size for a certain process via user constraint? The goal is to either have the capacity of a technology be zero or greater than or equal to a minimum size. i.e. VAR_Cap = 0 or VAR_Cap >= MinSize
3) Is it possible to have a supply curve for a resource that starts off more expensive and decreases the more of the resource you use?
4) If these options are not possible, then I think I can probably accomplish something with lumpy investment, but I was hoping to accomplish this without resorting to lumpy investment, which I believe can up model run time significantly.
Any answers, suggestions, comments are greatly appreciated. Thank you.
Chris
