Hi
I have modeled the electricity demand for Pakistan from base year 2014 to 2040 they key assumptions I have used are population, household and GDP. On the basis of these key assumption have developed three scenarios of electricity demand low growth average growth and high growth. In current accounts the data are population=196 million, household=31.6 million while for the low average and high I use growth function having different growth values. For the base year electricity demand data of 10500 MWh i have put in the current account of total energy section (electrcity demand). when i run this model it show the uniform demand from base year to the end year no changing throughout the period. the screen shots of all these model step are attached. I think the model not attaching the key assumptions how it attached the key assumption data. thanks

Hi Abdullah,

Thank you for your question and for providing the screenshots. The number (105000 MWh) entered at Demand\electricity demand:Total Energy is inherited from Current Accounts directly into your scenarios. Until you change the expression under each of the new scenarios, it will give exactly the same result as its parent scenario. The expression is not related in any way to the Key Assumptions you have included in your model.

In the expression box, you can input a formula using LEAP's many built-in functions as well as reference values of other variables. For example, if you want the electricity demand to change at the same rate as your population key assumption, you could enter the following expression into the Total Energy variable for each scenario:

GrowthAs(Key\population)
