Is it reasonable for large property users to double the power consumption?

Reasonable explanation, the loss of electricity fee must exist, but you didn't say what electricity price the property company charged you, civil electricity or commercial electricity?

40 times is the ratio under lossless conditions, but in fact, the current transformer itself has electrical loss, and the transmission line has electrical loss. Only the conductive material with a resistance of 0 has no electrical loss and basically does not exist.

In addition, your electricity meter has not been connected to the household. In this case, the electricity price charged by the power bureau to the property company is basically the commercial electricity price. If the property company charges according to the civil electricity price, then this 80 times is basically the electricity price ratio in addition to the current ratio. Commercial electricity is basically twice as much as civil electricity, and the extra points are for power loss, not more than 40 times. In fact, commercial electricity is graded, and 0.9 is the basic price. if

The basic electricity price is as follows, which may vary slightly from place to place. You can check your local electricity price.

The best way is for your merchants to unite and find the power bureau to add electricity meters to your home, and pay the electricity bill directly to the power bureau, so don't worry about the property company making the difference.
