2589 Views Hello,
I have a question concerning the reporting of the final energy consumption results (energy demand final units).
One of the energy policy targets in EE, is to achieve a certain percentage of RES use in final energy consumption.
In my model, I have entered consumption data in each end use in the demand sector (e.g. electricity for heating, solar for warm water etc.). Is it possible to see in the results how much is the RES use in the final energy consumption?
Or LEAP displays the consumption data only in the way they were entered?
Thank you in advance.
Sincerely,
Argiro

The results view in LEAP allows you to view energy demand results by branch (i.e. the way data was entered into the tree), by fuels (which can be grouped into user-defined groups - e.g. renewables), scenarios and years.
Does this answer your question?

2584 Views Hello Tory,
You can't actually see the use of RES in the final energy consumption, when electricity is the fuel.I was wondering if I was missing something about the way LEAP displays results.
But if it doesn't take into account transformation data, I guess it is not possible.

2583 Views I think I do not fully understand your question. Can you be more specific about what you are trying to model and what results you are trying to see?

2581 Views Ι am trying to model the national energy system and one of the things I want to see is the % of RES in the energy mix.

I'm still not entirely clear on what you result you are trying to see.
Take a look at the screen shots below to see if they capture what you are looking to model.

2569 Views Allocating primary energy and transformation back to demands seems like a good idea but when I tick "allocate primary energy and Transformation emissions back to demands" an error occurs.
I have sent it to leap@sei-us.org.

2568 Views Thanks, Argiro. This does seem to be a bug in 2011.0.0.16. We will take a look and let you know when it is fixed.

I still can't allocate primary energy and emissions from transformation back to demand. I have sent the error report in leap@sei-us.org.

2550 Views Hi Argiro,
The error report that you sent was from LEAP version 2011.0.0.12. Please update to the latest version using the Help: Check for updates menu. in order to be able to use the allocate to demand feature.

2547 Views Hello Tory,
I have allocated primary energy and emissions from transformation back to demand. However, the results are not how I expected them to be. For example, I assume that by doing that, there would an electricity "breakdown", but in the primary energy demand lignite is very low, and this is not right because our electricity system is based on lignite mainly.
I should also note that I have two electricity production branches, the interconnected and a smaller one for the islands.I have placed the islands system higher than the interconnected as you have suggested. The islands system uses residual fuel oil and lignite is only used in the interconnected.
Could this have something to do with the fact that lignite seems so low in the primary energy demand?
Thank you in advance.

2537 Views Hi Argiro,
The allocate to demands methodology will not work well with more than one electricity generation module. It will mainly use the first (i.e. higher) module and will not be able to correctly model any subsequent electricity generation modules, which is what you are seeing.
If you want to keep the complexity of the model you have created (with more than one electricity generation module), I recommend that you do not use the allocate to demands methodology and instead process your results in Excel to create the results you are interested in.
Best,
Tory
