    Hello!

    I have a question regarding the "Maximum Availability" parameter. When I input exogenous capacity and historical production data, LEAP generates maximum availability values (as shown in the attached image). However, when I run a base-case scenario—upon which the other mitigation scenarios will be based—there is no additional capacity added, yet the future production does not align with the historical production (as shown in another attached image).

    It seems there might be an issue with the maximum availability values, as the generation either increases or decreases even though the installed capacity remains the same. Could this discrepancy be related to an error in how we're inputting the historical production or exogenous capacity data instead?

    I would appreciate your insights on how the "Maximum Availability" parameter influences future production and whether it might be a data issue.

    Thanks!

    Hi Jessica -

    The column labeled "2023 Availability (%)" is provided only for your reference, based on exogenous capacity and historical production, as you point out. It looks to me like you've transcribed these values into the Maximum Availability variable, which limits the maximum energy production from a process, but it does not predetermine the energy production from a process, which depends on the module's requirements. For more information about how LEAP simulates energy production in scenarios, read the following (which are relevant if you are not conducting an optimized dispatch):

    Hi!
    Thank you. We are conducting an optimized dispatch.

    What also confuses us is that the production of certain processes decreases after the first simulation year, even though capacity is not retired. Do you know why this happens? Since production decreases so rapidly within just one year, LEAP has to add unreasonable amounts of new renewable capacity, which isn’t realistic


    Thanks again!
