    Hi,

    I am checking my LEAP results about the energy input (consumption) per technology in the base year.

    The issue is that LEAP results about energy inputs(consumption) of coal, LNG power technology are quite different from the national statistics (based on high heating values).

    Of course, electricity generations and efficiencies parameters are similar to national statistics because I calibrated them in the base year.

    I looked at the fuel table and adjusted Net energy contents, low/high heating value ratio to be same as the national statistics.

    But coal, LNG inputs are about 30% larger in LEAP. I wonder why this happens? I want to calibrate energy inputs results to the same level of national statistics, but I don't know how to do it.

    Thanks for your help in advance.


    Best,

    I'm not sure exactly which results are incorrect in your model, but I'd suggest working your way backward from demand to transformation, and checking each sector in turn to see where your model differs from the results you are trying to calibrate against.

    For example in my model, coal power generation is 183.5TWh, efficiency is 39%. One can simply guess total coal energy inputs by 183.5TWh/39% = 470.5TWh. When converted to toe, it becomes 40,456 (1000toe). This is the number I expect from LEAP and it is similar to the national statistics 39,539 (1000toe).

    But LEAP shows 57,700(1000toe) (in results view of transformation-input, resource imports ) . This is 45% larger than I expected.

    I adjusted the fuel table of "Coal Bituminous" in terms of "Net energy Content" to be same as national fuel statistics.

    I wonder what other factors may affect the result views of fuel energy consumption in LEAP.
