esum function

General

I am wondering if it is possible to sum VOM costs over the entire network using the esum function, as one can with fuel costs.

For example, esum('ENET.FUELCOSTRATE.(%)') returns a float but esum('ENET.VOMCOSTRATE.(%)') returns an error message Invalid Input Argument!

Hi @emmacooper,

I’m sorry to hear of this challenge you experienced! The property name you want to use here is TOTVOMRATE, not VOMCOSTRATE. I’ll share your confusion about this slight syntax inconsistency with the team.

Happy modeling!
