Describe the workflow you want to enable
Currently, the transmission line investment cost input to Switch is a single value for the entire country.
Big picture: we want to develop a workflow that can modify any or every investment cost value for each transmission line around the country.
This is step 1 of that process: allowing for an override process while also ensuring that each transmission line has an investment cost value.
Describe your proposed implementation
Unlike issue #98, this feature request appears to be (a little) more involved. There currently is no function like build_gen_build_costs for transmission lines and thus likely needs to be added.
Similar to Issue #98, we also likely want an optional parameter input to grid_to_switch.py that could be a Series, Dictionary, or DataFrame to set trans_capital_cost_per_mw_km for each branch.
This will need an additional column in the branch data sent to Switch
This parameter has
Index branch_id
If it is a single column, it is assumed to apply to all investment years.
If it has multiple columns, then each column is assumed to map to a particular investment year
Describe alternatives you've considered, if relevant
None at this time.
Additional context
There is an open question of how to handle hypothetical branches that don't correspond to original branched: similar to issue #69 for plants
