I'm trying to simulate the optimal least-cost energy mix and the following (see image) optimized new capacity variable is calculated.

Any thoughts about this problem.

Thank you in advance.

Can you explain why these results are a problem? What type of result were you expecting to see?

Based on the screenshot, it looks like LEAP is functioning correctly. But we won't be able to provide much assistance without understanding more about your model, and specifically what issue you are experiencing.

Thank you for your prompt response. For instance, small hydro plants cannot have this production (Capacity Factor higher than 100%) with so small capacity (compared with wind and PVs).

Any idea for this issue or where should I focus on regarding my inputs.

Thank you once again.

The warning message that you see (dispatch exceeded plant's rated availability) occurs in your model's historical period - in other words, before LEAP begins to perform its own dispatch calculations, which for optimized scenarios begin in the model's first scenario year.

So the diagnostic message is a result of the total capacity, together with the Maximum Availability and Historical Production variables. You could fix this (perhaps by increasing the Maximum Availability variable in 2011, 2013 and 2017, or reducing Historical Production), but it isn't vital. During the scenario period when LEAP performs its dispatch calculations, it will ensure that the plants' availabilities are not exceeded.

Best,

Taylor

In the Diagnostics I get this message.

A potential solution to this problem would be the increase in the maximum capacity addition?

Thanks once again.

That could be one solution. If left completely unconstrained, LEAP should have no difficulty meeting it's capacity needs. So, if you relax that (or another) constraint, this could address the diagnostic message.

Best,

Taylor
