Dear Team,

I am trying to build a model of gradle-to-grave LCA for transformer, and do not know how to model the use phase of a transformer. It is suggested that the main environmental impact at this stage comes from energy losses (load and non-load losses of transformer), I have data on the losses experessed in kW, but not sure what flows need to be included to represent energy loss, and should it go to Input or Output? Do I understand it correctly that I can use energy flows (as an Input or Output?), but first transform the known power value into energy metric?

You could certainly model energy losses as emitted heat if that's important to your system. I would expect though that the primary reason why this loss is important is because it requires inputs upstream when the loss is greater. That is, for your process you may have 1.1 units entering to produce 1 net unit. Because of that loss, creating that extra 10% will have 10% greater impacts upstream
