I am building a model to explore changes in the reserve margin given different scenarios. I have chosen to provide load shapes for each demand device (only considering electrical technologies). After I try to run the model I am getting an error message saying that the load shape values sum to 1300% (Figure attached). I have already checked the yearly shapes and made sure that they sum 100%, but for some reason I keep getting the same error. Furthermore, the error refers to a technology branch that runs on Gasoline, which is weird taking into account that I defined to only show load shapes for electric technologies. I am also attaching he area for your consideration. Any comment or suggestion is welcome. Thanks in advance for your time and patience.

Kind Regards,

Sorry about this, what you're seeing is a bug in LEAP that we'll be addressing in an upcoming version. Instead of selecting "Only show load shapes for electric technologies" under Basic Params: Calculations, you will need to ensure that the Load Shape variable is shown for all fuels. You will then need to create a load shape to assign to each of your non-electric technologies, and then assign it using the YearlyShape() function - just as you would for the electric technologies.

Since you may not know (or care) when these other fuels are being consumed across your time slices, consider creating a dedicated load shape that is "flat": one which has the same power requirements in each of your 13 time slices (note that the value entered into the yearly shape will depend on the duration of the time slice, so that you obtain equal power requirements in each slice), and which you may then assign throughout the demand-side of the model for non-electric technologies.

Hope this helps,

Taylor

Thank you very much for the answer Taylor, your suggestion solved the problem.

Cheers,
