2759 Views Hello,
I have inserted the activity levels of the different industrial sectors in my model as shares (%) of the total gross value added of the Industry sector.
The problem is that in the final energy intensity (in my model the final energy intensity is: total energy consumption/activity level) LEAP doesn't seem to recognise that the denominator is a percentage of the total value added.So, it doesn't calculate the real activity level of each industrial sector. For example if a share is equal to 20% of the total GVA, it simply sets as denominator the number 20.
(total energy consumption/20)
Do you have any idea how I could resolve this?
Thank you in advance.
Sincerely,
Argiro

2746 Views Hi Argiro,
When you use the "Activity Level" variable, LEAP will reference the value of activity level at the current branch. In your case this could be a percent.
What you want to use is the variable "Total Activity" - this will multiply activity levels up the tree to give a value in absolute units as defined at the top branch. So you want to change your final energy intensity equation to total energy consumption/total activity.

2744 Views Hello Tory,
Thank you for your quick response.
So, if I understand correctly, when I write total activity in the denominator, LEAP will automatically use the activity level of the particular sector.
Thank you!
Best Regards,

2740 Views Correct - assuming that is the way you have it set up.
For example, if your structure looks like this:
Demand (no data)
- Industry (Activity Level = Value Added [Absolute Units] = A)
-- Industry Subsector (Activity Level = % of value added [%] = B)
At the bottom branch (Industry Subsector):
Activity Level = B
Total Activity = A*B

2557 Views Hello,
I am doing a study of the electricity sector of West Java, Indonesia.
I have some questions concerning the activity level of the sectors' demand on electricity and particularly on what is the most consistent way to express the activity levels and the final energy intensities of the commercial and the industrial sector.
The Electricity Demand tree of my analysis has the following scheme:
Demand (as of data from year 2010)
1)Household [10.75 Million Households]
Electricity
Activity Level[%]=70 [electrification rate in West Java] percent saturation of Households
Final Energy intensity=1,64 MWh per household (divided final electricity consumption of household sector with the number of houses that consumed electricity)
2)Industry: I have data of used electricity per industry (23 industries in total) expressed in Million Rupiah, as well as the value of Gross value added per industry expressed in Million Rupiah and the final electricity consumption of the Industrial sector in general expressed in GWh.
3)Commercial : I have total surface area of commercial buildings land use expressed in Hectares and the final electricity consumption of the sector in general.
Can you please suggest a way to integrated the available data in LEAP? Would it be appropriate to conduct a useful energy analysis for the abovementioned sectors given the availability of data?
I would also be grateful to anyone having more detailed data (e.g tones of West Java industrial production, ) of the electricity demand of commercial and Industrial sectors in West Java forward to me.
Best,
Ioannis

If you have gone through the LEAP Training Materials, you saw an example of a data set which uses different activity levels for each sector and even uses different activity levels within a single sector when necessary.
There is no "right way" to set up the structure of your model. I would recommend setting up your tree structure in a way that lends itself to the data available and includes the ability to say something significant in scenarios. This typically means selecting Activity Levels for which you have projections into the future and which you think are good indicators of changes in energy intensity for that sector.

2543 Views Hi Tory,
I went through the GHG training exercise and realised that in my case (given the data availabilty) it makes more sense (simplify my model) to set the activity level of the Industrial, Commercial and Puplic sectors in to No Data and thus express the final electricity consumption to be equal to the final energy intensity of these sectors.
Thank you for your consideration.
Best,
Ioannis
