EQ_COMBAL.M (Commodity Balance- Marginal) vsaini Vinay Saini Posts: 67 Threads: 24 Joined: Jan 2016 27-12-2017, 11:29 AM Dear Dr. Antti, Greetings of the day. Dr. Antti, I am using the value of EQ_COMBAL.M (Commodity Balance- Marginal) in M USD per PJ to calculate the commodity marginal price at hourly level. I would like to know whether the value of EQ_COMBAL.M shown at various model result years (such as 2020, 2025, 2030, etc) in the model are discounted to model base year (base year is 2012 in my model) or undiscounted values of the result period?

The EQ_COMBAL.M values reported by TIMES are undiscounted yearly values. The undiscounting factors UNDISC(r,t) for each region r and period t are: UNDISC(r,t) = ∑(periodyr(t,y), obj_disc(r,y)) where periodyr(t,y) is the set containing the individual years y in each period t, and obj_disc(r,y) is the parameter for the discounting factors for each region r and year y. EQ_COMBAL.M(r,t,c,s)(reported) = EQ_COMBAL.M(r,t,c,s)(solver) / UNDISC(r,t) vsaini Vinay Saini Posts: 67 Threads: 24 Joined: Jan 2016 27-12-2017, 05:24 PM Thanks for the prompt reply Dr Antti.

I could see only a small description in the documentation II. I am using this as my cost of electricity.

If you mean interpretation, see https://iea-etsap.org/docs/times_interpetation_dual.pdf.
