Greetings for everyone.

I'm Damar from Indonesia. I would like to us about how to input the damage cost for externality cost. I have checked the check box for cost in Basic Parameters and also the check box for externality cost in Costing Tab. But I couldn't found where I can put the variable of damage cost for each pollutants. Anybody could help me to did the damage cost analysis?

Thank you very much

Best regards,

Hi Damar,

Thank you for your question. Once you have enabled Costs and the Externality Cost checkbox (both in Basic Params), you must add pollutants under the category called "Effects" which appears in your tree, underneath Key Assumptions. You will then see the Externality Cost variable appear at these branches.

Additional information can be found at the following thread:

Hopefully this helps. Should you have any more questions, please let us know.

Thanks!

Hi Emily.

Thank you very much for your help and your very fast response Emily. Now I am able to put the damage cost in my LEAP.
Then, I have some following questions.
Actually, I would like to know the effect of some damage costs from multifarious power plants. I read the thesis of Mr. Muhammad Ery about Jamali (Java-Madura-Bali) Interconnection and found that damage cost of pollutants for each power plant is vary one to another.

Let say some examples of Damage Cost:
1. CO2 for Coal Fired Power Plant 2.45 Cent/kWh
2. CO2 for Oil Fired Steam Power Plant 1.96 Cent/kWh
3. CO2 for Natural Gas Fired Steam Power Plant 1.34 Cent/kWh
and so on..

How to put them in diversities damage cost like those? Because in Effect (mentioned by you before), damage cost is very universal, or in another words for CO2 in any transformation plants have been assumed to be same.

Second, in the result (Summaries). I see that the results only shown cumulatively from the base year result. Could you help me to make the results appeared in each year so we could track the increase of damage cost?

Thank you Emily.
Have a great day!

Best regards,

Hi Damar,

You're welcome! Glad it worked out.

To answer your first question, the "damage cost" (or the Externality Cost, in LEAP) can be specified per unit of pollutant mass (i.e. USD / tonne of CO2) or volume, not per kilowatt-hour generated. The separate emission factors and separate efficiencies that you have already provided for each power plant mean that you are effectively assigning different externality costs to your plants per unit of electricity production. If you wish, you could use LEAP to calculate the externality cost per kilowatt-hour, but this is an output, not data that you need to provide as input.

To your second question: it sounds like you're viewing cost results using LEAP's Summary view, which displays a cost-benefit summary for your area. This is one specific type of result, but you may generate more specific cost results using the Results view. In Results, select Costs: Social Costs, which will allow you to display results for each year by picking "All Years" on the chart's x-axis. You may configure the result in any way you wish - for example, using discounted or real costs, displaying by branches in your tree or by social cost category, etc.

Thanks!
