Ah… ok, so I guess you only pay for transmission into the house and not out of the house. Thus there are two thresholds I need to take into account.
- What decides when to shut down your own export is the pure electricity price
- What decides when to shut down your own production, turn every possible heating/cooling device on and open all the windows
is the sum of the electricity price and the transmission cost.
would this be about right?
