First Simulation Year

See also: Analysis View, Transformation Analysis

When dispatching processes to try and meet the energy and power requirements for each module, LEAP can operate in two different calculation modes as follows:

1. Historical dispatch is used in each year before the First Simulation Year.  In these years, LEAP runs each process up to the amount specified in the Historical Production tab.  If the amount specified in the Historical Production tab would cause the process to exceed its maximum available capacity, LEAP displays a diagnostic error message.  

2. Simulation: From the First Simulation Year onwards, LEAP simulates dispatch using the Dispatch Rule specified for each process.

Tips

1. If you want dispatch to be simulated in ALL years (i.e. you want LEAP to never use Historical Production values) then set the First Simulation Year to a year before the base year.  

2. Conversely, if you want LEAP to always use historical production values set the First Simulation Year to a year after the study end year.

3. This variable is set by default to the expression FirstScenarioYear.  In other words, simulation starts in the first scenario year.  The First Scenario Year is set on the Years tab of the General: Settings screen.
