Limit_Shadow Column
Units = $/MMBtu
The value of the constraint (in currency per heat-rate heat content, typically $/mmBtu) when using the Fuel Optimization logic. For instance, if the fuel limit is increased by one unit (1 mmBtu), this value represents the reduction in total system production cost (in $). The higher the shadow price, the more binding the constraint. As expected, when the Usage < Input_Limit, then the Shadow Price = 0.
