Dear All

I am facing a problem in the electricity generation sub module under Transformation module. I have given my present demand and also the future demand for the model. But when i run the results, in the Transformation Module,in Electricity Generation- it doesnt calculate the electricity according to varying demand in future. The electricity generated in results is same in future years as the current year.

Please let me know where the problem lies here

Hi Isha,

There are a few reasons that this could happen. My first guess would be to check if you've allowed LEAP to build additional capacity as demand increases (via the endogenous capacity tab, in your scenarios), if you have only specified enough exogenous capacity to meet electricity demand in the base year. You can also ensure that these additional demands are being 'seen' by your electricity generation module, by viewing Results, and checking Transformation:Requirements for this module. This will tell you if additional demands are actually being placed on the module itself.

Through it's Results view, LEAP allows you to conduct careful debugging of your model by checking intermediate steps. I think you'll find it very useful to explore several different results, and look for inconsistencies with what you expect.

Let me know if you're still stumped after a good look through.

Good luck,

Taylor

Dear Taylor

Thanks a lot for solving the query. I added the endogenous capacity and in electricity generation module it reflected the generation capacity. But I think the electricity generation module is building capacity only by taking into account of endogenous capacity added. Because in my scenario the demand is actually decreasing in future years, so electricity generation module should take this point and electricity generated should correspond to decreasing demand, which is not the case in actual results.

Can you please clear that why is this case happening? How can i check that electricity generation module is taking the demand for its calculations?

Thanks much

Hi Isha,

Have a look here to better understand LEAP's endogenous capacity calculations:

http://www.energycommunity.org/WebHelpPro/Transformation/Endogenous_Capacityu_Expansion_Calculations.htm

A few things to check will be the reserve margin that you've set for your module (the amount of additional capacity required, beyond that which is required to satisfy demand, and from which endogenous capacity additions are determined), as well as the Dispatch Rule that you've set for all of the processes within your module.

Again, have a careful look through the Results views Transformation: Requirements, Outputs, Capacity and Capacity Added, as well as Demand: Energy Demand Final Units to give you a clearer picture of what's going on in your area. If you think that your results are being incorrectly calculated, you can send you model to leap@sei-us.org and I'll have a quick look.

Best,

Taylor

Dear Taylor

Thanks much for your quick reply. I look into the points and areas you mentioned and verify my model calculations. If i do not find the problem, then will send you the model.

It will be a great help if you could have a look into it and let me know the lying problem.

Thanks much
Best Regards
Isha
