Hi!

How should I enter data about CHP-s?
If i have data, that Electrical installed capacity is 390MW and Thermal installed capacity is 1465 MW, then should I enter this data under "exogenous capacity" - 390+1465=1855 MW?

If I have data, that Electrical Efficiency is 19%, Thermal Efficiency is 51% and Overall Efficiency is 70%, then does 51% goes under "Process efficiency" and 19% goes under "Coproduct efficiency"? (Electricity is co-product)

And also, if I have data about, how much Electricity and how much Heat CHP technology produced in current year, then can I use this data somewhere in LEAP? (I currently have'nt found, where I could enter this data)


Best,

Tanel

Hi Tanel,

Can you please review the following forum post which goes into detail about how to model CHP plants for electricity generation?

Please let me know if you have additional questions.

Hi Tory,

Thank you for your reply. Indeed, I got most of the information from the link you gave me.

But still I have one question: What about the capacities?
If i know Electrical capacity and thermal capacity, then should I add them and enter this value to "Exogenous capacity" ?

Hi Tanel,

The previously linked forum post describes two ways to model a CHP system, one where electricity is the main output and one where heat is the main output. If electricity is the main output, then electrical capacity should be used in the "exogenous capacity" variable.

Then both the "efficiency" variable (electrical efficiency) and "co-product" variable (heat efficiency) in addition to the amount the module runs will dictate how much heat is produced.

Best,

Tory
