Veda2.0 Released!

I advised you to read the documentation, Part II, section 4.1 Combined heat and power. See Part II.

You have apparently been reading Part IV, which I have never read myself. It is a VEDA documentation, not TIMES. So, once again, please just read Part II, and everything should become clear.

Some comments to your remarks, which were apparently based on reading Part IV:

> Back pressure turbines [...] The CHPR attribute is then fixed (FX), so the production of electricity and heat is in a fixed proportion, but one could also use a (LO) CHPR for defining the back-pressure point, if so desired (to allow bypassing the turbine to produce more heat).

Correct, you should use CHPR(FX) for back pressure turbines, and CEH=0 or unspecified. The CHPR(LO) option (instead of FX) would allow the process to produce also purely heat, with the same overall efficiency. That might indeed be also reasonable in some systems.

> My questions are : Let´s say i want to model only Back pressure turbine process producing ELC and STEAM. Parameters i need to use are  electrical efficiency, CHPR FX (Fixed) or LO ?, load  utilization and CEH. 

No.  You should not use CEH for a back pressure turbine, as you can see by reading section 4.1 Combined heat and power, and especially subsection 4.1.2.1 Back-pressure turbine systems.

> I have only ELC efficiency= 0.1638 and HEAT efficiency= 0.7024 computed for year 2018, (Produced ELC / Total fuel input and Produced HEAT / Total fuel input)

I don't quite understand, have your numbers changed again?  In your Excel file, your expected HEAT efficiency was only 0.518777 (the total heat output was 12.0393 and total fuel input was 23.207, as calculated by you). But the ELC efficiency 0.1638 does match with your Excel.
