Hi, The results of our model shows fast changes in investments in new technologies over the model's time period. We wonder if there is a method to slow down these changes. Could we use the "Decayr" attribute. If yes, how could this attribute be used? Best regards, AkramS
There is no "Decayr" attribute in the ETSAP TIMES model generator.  Are you referring to some other modelling system? If using TIMES, you could use the technology-specific dynamic constraints for bounding the increase/decrease in capacity/activity, and with the general TIMES user constraints you can formulate almost any kinds of constraints for any sets of technologies, including dynamic constraints limiting the increase/decrease in activities, capacities, flows, and investment costs between periods. Please see the documentation: Part II: Comprehensive Reference Manual   – Section 6.3.39 for technology-specific dynamic bounds on growth/decay   – Section 6.4  for general User Constraints
