Appendix A RESULTS TIMES Attributes

Table 1 provides a list of TIMES results attributes produced by the gdx2veda GAMS utility from a TIMES run GDX file, according to the times2veda.vdd directives (see Appendix B) and the reporting options (see Part III, Section 3.10) invoked with the run. Not all attributes listed will appear in every Results database. Many attributes will not appear if the driving input attributes were not used in the model input. See Part II, Section 3.3.1 for more details on the TIMES reporting parameters.

Cost-benefit and ranging indicators for process (p) in period (t), where uc_n is the name of the indicator:

  • COST - the total unit costs of VAR_NCAP (in terms of an equivalent investment cost)
  • CGAP - competitiveness gap (in terms of investment costs), obtained directly from the VAR_NCAP marginals (and optional ranging information)
  • GGAP - competitiveness gap (in terms of investment costs), obtained by checking also the VAR_ACT, VAR_FLO and VAR_CAP marginals, in case VAR_NCAP is basic at zero
  • RATIO - benefit / cost ratio, based on CGAP
  • GRATIO - benefit / cost ratio, based on GGAP
  • RNGLO - ranging information (LO) for VAR_NCAP (if ranging is activated; in terms of investment costs)
  • RNGUP - ranging information (UP) for VAR_NCAP (if ranging is activated; in terms of investment costs)

* p = process, c= commodity, r = region, t = period, s = timeslice, and v = vintage

In addition, the r,t,s,v dimensions are involved for attributes involving processes, and the r,t,s dimensions for attributes involving commodities only.
