2657 Views When I input data in value the field,I find it is impossible to change the original data.How can I change those datas? Thanks.

2656 Views Hi Serena,
I'm afraid I will need a little more information in order to understand what is going on. I see that you are using LEAP version 2011.0.0.14 and that you have a license.
Can you please please tell me what specific steps you are taking to input data (such as entering data explicitly in the expression field in the upper right pane of the screen, using the function wizard or using the expression builder).
Please also tell me which view you are in, which variable you are editing, and which scenario you are in. Please let me know if you are getting any error messages.
Best,
Tory

2646 Views Hi Serena,
I think what you are talking about is the situation where you are in the Reference scenario. In this case the expression fields will show you the value for the last historical year (in this case 2000 for Freedonia) and will be fixed. When you are in the Reference scenario the field that you edit is for years from the first scenario year to the end year (2001-2030 for Freedonia). To see what these years are for any area, go to General: Basic Parameters: Years tab.
To edit the historical years of data, you must change the scenario to "Current Accounts." To do this go to the drop down "Scenario:" menu immediately above the expression fields.
To try out many of the basic features in LEAP I recommend going through the LEAP training materials which you can find at the url below.

2631 Views Hi Tory,
I meet some trouble when I did excercises."A range of measures including new lighting standards and utility demand-side-management programs are expected to reduce the energy intensity of electric lighting in urban households by 1% per year (-1%/year), and to reduce the expected growth in electric lighting intensity in rural areas from 1% (reference scenario) to 0.3% per year (+0.3%/year)". How can I express in the ecpress fields.
Additionally,when I click the result boton accrording to the excercise,the error is like this,"Problem with endogenous capacity addition calculations.Check you have specified sufficient capacity. Branch:Transformation\Electricity Generation\Processes\Oil Combustion Turbines".
Lastly,what's the differrnces between endogenous capacity and exogenous capacity? And what's the meaning of capacity credit?Where can I input the electricity generation and capacity data?

Serena

Please note that these training materials were designed for LEAP2008, and therefore you may find a few discrepancies in the results and screen shots. We hope to have a new version of the training materials up on the website in about a week.
The lighting expressions for the DSM scenario (Section 1.6 in the training materials) calls for 2 separate expressions: one for urban households and one for rural.
Firstly, the DSM scenario expects a decrease in energy intensity of electric lighting of 1%/year in urban households. This can be represented by the following expression:
Growth(-1%)
Secondly, the DSM scenario also expects an increase of electric lighting intensity in rural households of 0.3% per year. This can be represented by the following expression:
Growth(0.3%)

For more information on the concept of capacity credit, I recommend reading Wikipedia's article for a simple definition or the Riso National Laboratory report for a more detailed definition.
