Shortfall and Surplus Calculations

See also: Transformation Calculations

Once LEAP has calculated the outputs from each process in a module, it uses the settings you specify on the Output Fuel Properties screen to simulate how LEAP deals with situations of shortfalls and surpluses in the production of each output fuel.

• Under shortfall conditions requirements unmet by production can either be met with additional "gap-filling" imports, or they can remain unmet. Notice that this latter case does not necessarily imply that a requirement is unmet in the system as a whole. An upstream module that is simulated later on may produce the same output fuel.

• Under surplus conditions additional production can either be exported or wasted.
