Turning off state RPS/CES policies doesn't turn off state-level forced fossil retirements

[aschleif]

Summary

Setting GSw_StateRPS to 0 turns off state RPS and CES constraints so that these policies aren't enforced, but it doesn't turn off the forced retirements defined in \state_policies\forced_retirements.csv.

Update: It seems like this issue exists when GSw_Retire=0 but not otherwise.

The file forced_retirements.csv gets copied over to inputs_case and processed in WriteHintage.py to produce inputs_case\hintage_data.csv independently of any switches.

Potential Solutions

In b_inputs.gms, something like:

* Force retirements if state RPS/CES policies are turned on
if(Sw_StateRPS = 1,
  forced_retire(i,r,t)$[sum{st$r_st(r,st), (yeart(t)>=forced_retirements(i,st))$forced_retirements(i,st) }] = yes ;
* If the technology you would upgrade to is part of forced_retire, then include the
* upgrade tech in forced_retire
  forced_retire(i,r,t)$[upgrade(i)$(sum{ii$upgrade_to(i,ii), forced_retire(ii,r,t) })] = yes ;
) ;

And a similar if statement in WriteHintage.py.
