4 years ago Hi Freddy, thanks, I can confirm it's failing on this setting (take default case with Germany, tick box for dispatchable 1 and for co2 constraints).
It's a bit weird, because it was working before.
@FabianHofmann It seems to be a problem with the emissions in nomopyomo constraint, see error message. I'll try to get a minimum example where it fails.

Hey PyPSA Team,
thanks for this nice tool. We are using it in our lecture to make and discuss rough capacity estimates for wind and solar in different countries. If both options CO2 constrain (Limit on CO2 emissions) and Dispatchable technology 1 are selected, the solver gives an error and indicates that the job could not be executed.
Thanks for your work Best Freddy
