Hello, I am modelling new electricity generation capacities to meet CO2 cap limits but this strange capacity growth occurs in the first years and then goes down. Also, LEAP displays zero costs from generation despite having introduced fixed, capital and variable costs. Could someone help me understand what could be going wrong?
Thank you very much

Hi Humberto,
LEAP adds capacity to meet energy demands, reserve requirements and replace retiring plants. If the existing capacity is insufficient to meet these conditions, you will often see a jump in the first year the simulation is run. This most likely occurs due to a mistake or inconsistency between energy demand and supply. I recommend checking the values, scale and units of the Energy Demand results as well as the Exogenous Capacity, Efficiency and Availability variables to ensure that they make sense. If anything stands out, make the necessary changes in Analysis View.
As for the cost issue, can you send a screenshot of the cost results that you are seeing (Investment Costs and Social Costs)?
Thanks,
Emily
