UPV prescribed builds

[ssattler]

We are trying to reflect some future utility-planned UPV projects in the model, and I revised the upv_prescribed_builds_reference_ba.csv, upv_prescribed_builds_open_ba.csv and upv_prescribed_builds_limited_ba.csv files in the inputs/capacity_exogenous folder to reflect these projects by MW, BA and year. We're not seeing the UPV builds we wanted to prescribe when we run the model. Where do you define UPV prescribed builds? Thanks.

Sandra - you should be able to update the plant database (ReEDS_generator_database_final_EIA-NEMS.csv) directly and see the prescribed builds show up from there. The database is used to create PV prescribed builds in writecapdat.py starting here.

We recognize this is confusing, and have work going on right now to clean this up, so hopefully this will be much more straightforward later this summer when we have that cleanup-up version finished.

Thanks Wesley. We're also running a scenario that looks into limiting the amount of wind the model can build in MISO-South. Are the wind_ons_exog_cap files similarly created, or could those be changed to add these build limits? Do you have a recommendation on where we can define year-by-year build limits for an RTO?

[wesleyjcole]

You should be able to change the exogenous build files to prescribe the buildout in a region. You can also use GSw_GrowthAbsCon with applies an absolute growth limit. It is applied to the full region you model, so if you model only a single RTO, it would apply the growth limit to that RTO. If you ran more than one RTO, then you would need to index the growth constraint by RTO which would require some development.

This is helpful, thanks. If we use GSw_GrowthAbsCon to model a single RTO, is there a way to define a growth limit by year?

[wesleyjcole]

Not out-of-the-box. growth_limit_absolute(tg) doesn't have a t index, so you would either need to add a 't' index to that parameter, or you would need to add some code that updates growth_limit_absolute(tg) after each solve year.
