Dear LEAP SEI . Hello, I'm Noval, a student of electrical engineering. My last project talked about energy planning in the transportation sector. and I have a problem with the result. Why is the value of the result of my data so high? What the problem?. The data are the number of flights on Lombok International Airport and domestic airport on west Nusa Tenggara. Activity level for this number of flights is operational hours. and I got data from Asumsion. final intensity form survey. I calculated and compared the result from Excel; the difference is very far. How do I fix this problem? the equation i use in excel is E= A*I (A is operational hours Flight)

Hello Ahmad,
Hard to tell from this information why you are not getting the result you expect. I'd recommend looking carefully at scaling factors and units. Make sure all the data you entered is in the right units and make sure the result units are those you need.
Good luck!
Charlie

I have a question: What variables are used in the final energy demand equation in leap?
Charlie Heaps 3/4/2025
That depends on which method you choose, but if you are using the default method then energy demand (E) is simply the product of activity level (AL) and final energy intensity (EI).
That is E = AL x EI
Bear in mind the Activity level is itself the product of the individual activity levels you specify at each level in the tree down through a complete branch path. So for example if you have a tree with 4 levels of depth below the demand branch, then AL = AL1 x AL2 x AL3 x AL4.
Hope this helps!
