Refrigerators really don't like to be shut off and I personally leave a light on and several boat dehumidifier heaters on when we leave for extended periods of time.Every apartment building basement has a designated area for electricity and gas meters that are labeled by apartment number with easy access by the company's meter readers. Water usage isn't metered yet, but AySA already has that in the plans soon.
There is an easy way to guarantee your usage stays at zero when you're gone for an extended stay. Flip the main electrical switch in your apartment. Locate the power box inside the wall and move the main switch to the opposite position. That way no power is used in your absence.
