Is there any method to constrain several processes so that the proportion of the total output from each technology is proportional to the relative capacity of each technology? For example, suppose ...

    Thread: Storage flows in user constraints
Post: Storage flows in user constraints

Is there any way to use storage input or output flows in user constraints? This could be useful for various reasons and feels like a gap in the model.

I've investigated further. It turns out that RPT_OPT wasn't doing anything in the case I was testing. Since I had defined emissions at the ANNUAL rather than DAYNITE level, they were aggregated when...

Hi Antti, Apologies for taking so long to follow this up - a new baby arrived between your two messages. I didn't know the process for contacting the Project Head to agree changes to the code, so ...

Thanks, Antti. I'll contact George about it. If anyone else has any suggestions or requests on this topic, then please share them here!

Post: Report only annual flow data for ENV commodities

I'm running a model with a substantial number of timeslices, which produces very large GDX files. TIMES has an option to aggregate commodity reporting to the ANNUAL level using RPT_FLOTS.  However,...

Thanks for the explanation, Antti.  I can now repeat the TIMES investment cost calculation.   This is an interesting philosophical question that I haven't considered before.   Perhaps it depends o...

Hi Antti,   The COST/LEVCOST labels issue was my misunderstanding – I didn’t realise the information was included only in TIME_NPV.   I think I understand the results output now.  2012 is defined ...

Thanks, Antti.  You're absolutely correct - I was using the OBLONG switch but not the ANNCOST switch, and this was the problem.  I had read the section in Part 3 of the documentation on the ANNCOST sw...

Thanks, Antti. Looking again, I think I must have made a mistake extracting the 2011 vintage coefficient from the objective equation - I also have the correct number from the model equations and I ...
