Thread: Constrain a variable capacity factor to be the same for several processes
Post: Constrain a variable capacity factor to be the sam...
| 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. |

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 ... |

Thread: Report only annual flow data for ENV commodities
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,... |

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 ... |
