Historical Production

See also: Analysis View, Transformation Analysis

This variable specifies annual energy production (output) for a process,  You can set the scale and units used to measure the variable in each module.

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

  • Historical dispatch is used in each year before the first simulation year.  In these years, LEAP simply runs each process up 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 will display a diagnostic error message.  

  • Simulation: From the first simulation year onwards,  LEAP simulates dispatch using the Process Dispatch Rule specified for each process.

In earlier versions of LEAP you could only set historical production for the base year (in a variable called Base Year Output that has now been removed.  In the latest versions of LEAP you can specify historical production for any years before the first simulation year.  Moreover, this year can vary between processes.

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.
