V. Calculation of Energy Saving

1. Energy saving of each bill
   Energy saving of each bill = (average daily electricity usage in the same bill period of last year-average daily electricity usage in the current bill period) × days in the current bill period. Negative values are not adopted. The values are rounded up to the nearest decimal place (Unconditional Carry)

2. Average daily electricity usage in the same bill period of last year
   Average daily electricity usage in the same period last year = total electricity usage in the same bill period of last year ÷days in the same bill period of last year

3. Average daily electricity usage in the current bill period
   Average daily electricity usage in the current bill period = total electricity usage in the current period ÷days in the current period

4. The average daily electricity usage is calculated to the fourth decimal place.
