    Topic: Why is it that when I schedule future electricity generation, it does not show up exactly in the results?Subscribe | Previous | Next
  • Lucía Galán Cano 3/25/2024

    hello to all,
    I am modelling a model city in LEAP and, if I estimate that, by 2030, a total of 483.2 GWh will be generated (as can be seen in the first picture), the results show that a higher amount is generated.

    This amount practically coincides with the energy demand in this scenario. Why is this the case, and should any adjustments be made?
    I would be interested in the total amount programmed, because, in the Sankey diagram, I need the total amount of imported electricity (electricity demanded minus electricity produced) to be shown.

    Thanks in advance

    Hi Lucia,

    Please note that what you specify in the "Historical Production" variable, only applies to those years before the First Simulation Year (which you specify in a separate variable). This variable is generally used to specify historical generation, so, given that you are specifying values for future years (i.e. 2030), this won't be taken into account by LEAP if your First Simulation Year is set to the Base Year, or the First Scenario Year. Instead, LEAP estimates the total required generation in future years based on the final electricity demand, other "intermediate" demands created by transformation modules above the electricity generation (e.g. transmission and distribution losses), and any other import/export targets specified at the module level.

    If the generation amount you are getting, matches the electricity requirements (demand and losses), but you were expecting a lower number due to imports, it may mean that you haven't specified those. If you have any specific import targets for future years, you can include them in the "Import Target" variable under output fuel branch in your electricity generation module. On the other hand, i you want to limit the amount of generation in future years, you can also do it in different ways, depending on the modeling methods you are using. For example, you could use constraints on the Maximum Capacity, or the Maximum Availability of existing power plants.

    The amount of imported electricity can also be visualized under the Transformation results: imports into module, the module energy balance, or through the Sankey Diagram.

    Hope this helps!
