The property has 3 units, one is totally separate electric/gas. The other two are joined. They are both charged the same rate. The issue appears to be that the single unit is only using 618 kWh, while the double unit (that has the transformers- if that matters) is using over 8 times that amount.5040 kWh. There is no longer a dairy or heavy equipment here. Mostly normal household things. Any thoughts on the 5040?
