Setup for Calculation of Electricity Charges(as of September 2008)

Each month your meter is read to determine the amount of electricity you have used, and your electricity charges are calculated accordingly.

Note: Where customers have a Flat-Rate Residential Lighting contract, no meter is installed and therefore no meter reading takes place.

Reading of Meters

Each month on the meter inspection day, the reading of your meter is taken in order to determine the amount of electricity you have used.

Meter inspection day

This is the day in each month on which the meters are read to determine the amount of electricity used. Customers are informed of this day in advance.

Note: The inspection day for the following month is given in each month's Notification of Amount of Electricity Used.

Calculation of amount of electricity used

The amount of electricity that you have used is calculated by subtracting the previous month's meter reading from the present month's reading.

Notification of Amount of Electricity Used

Notification of Amount of Electricity Used

Notification of Amount of Electricity Used is delivered to you each month on the meter inspection day.

  • Contract number

    This is your electricity contract number with us.

  • Contract type

    This gives the type of your electricity contract.

  • Following month's meter inspection day

    This gives the day next month when we will come to your residence to read your meter.

  • Prompt and delayed payment rates

    The prompt payment period extends up to the 21st day following and including the meter inspection day. When electricity bills are paid within such period, the prompt payment rate applies.
    · For payments made after the end of such period, a delayed payment rate that is 3% higher than the prompt payment rate applies.
    This is charged by adding the difference between the prompt and delayed payment rates for the present month to the following month's bill.

  • Scheduled automatic transfer date

    The date on which the automatic transfer is to be made.

  • Amount used

    This gives the amount of electricity that you have used in the month.

  • Sum to be billed

    This gives the sum of money that you are scheduled to be billed for the month.
    * This sum includes money for consumption tax, etc.
    Note: For certain reasons there are times when this item cannot be indicated.

  • Renewable energy power generation promotion surcharge

    This gives charges of renewable energy power generation promotion surcharge, which is included in “Sum to be billed” for current month.
    * The "Renewable energy power generation promotion surcharge, etc." includes money for consumption tax, etc.
    Note: For certain reasons there are times when this item cannot be indicated.

  • This month's and last month's reading

    This gives the readings of your meter on this month's meter inspection day and the previous month's.

  • charge breakdown bar code
    You can see a breakdown of "Sum to be billed" in your mobile phone, etc.
    It is necessary for application in advance to display such bar code.
    When you apply for this service, we would appreciate it if you could contact us: phone number in other affairs, which is below one displayed two phone numbers in “Notification of Amount of Electricity Used”

    Note: There are times when this item cannot be indicated under some contract.
    (e.g. a contract for high voltage, a contract with customers who are delivered payment slip at our checking electric meter, and stuff )

  • Fuel cost adjustment charge

    Where fuel cost adjustment is implemented, this gives the applicable fuel cost adjustment charges for the current month.
    * Fuel cost adjustment charges includes money for consumption tax, etc.

  • Sum received (notified to customers paying by automatic transfer)

    The right-hand section of the Notification slip is a receipt for customers who pay their electricity charges by automatic transfer from a bank or postal account. This item states the previous month's electricity charge received from the customer's account and gives a breakdown of that charge.
    (In some cases this item may not be shown because e.g. the date of the automatic transfer does not permit it. In such cases a receipt is mailed to the customer on a postcard.)
    * The "Sum received" includes money for consumption tax, etc.

  • Service Office

    This gives the Chugoku Electric Power Service Office for the area in which you are using our electricity.

Calculation of Charges

We calculate your charges according to the amount of electricity we determine you have used.

Period covered by the calculation

For the purpose of the calculation, the period from the previous month's meter inspection day to the day before the current month's inspection day counts as one(1) month. This is the period that the calculation covers.

For example if the previous month's inspection day was August 16 and the present month's inspection day is September 17, then the charge for "September" will be the charge covering the period from August 16 up until September 16, thus:

Electricity charge for "September"

Where fuel cost adjustment is implemented:

Where fuel cost adjustment is implemented, a fuel cost adjustment amount is either added to or subtracted from the electricity charge as appropriate.

If you change address in the middle of a monthly period, your charge will be calculated on a day basis

If you terminate or start use of our electricity on a day other than a meter inspection day due to address change or other circumstance, we will calculate a charge for the number of days that you used our electricity during the monthly period in question.

If you start use in the middle of a monthly period:

We will calculate the charge for the period from the date when you start use up until the day before the next meter inspection day, thus:

Charge for period beginning from the day you start use

If you terminate use in the middle of a monthly period:

We will come and read your meter on the day you terminate use, then we will calculate the charge for the period from the previous meter inspection day up until the day before the date of termination, thus:

Charge for period up until the day you terminate use

Charge Calculation Method (for Meter-Rate Lighting A contracts)

Model calculation for when the amount of electricity used in one(1) month is 310 kWh
Note: This example is for the case where a discount is made for automatic transfer.

Calculation formula

Example calculation of charge for use of 310 kWh in one(1) month under Meter-Rate Lighting A contract

Category Calculation method    
Minimum charge
(covering initial 15 kWh)
330 yen 26 sen (1)  
Electricity energy charge Consumption past 15 kWh up to 120 kWh 20 yen 34 sen × 105 kWh = 2,135 yen 70 sen    
Consumption past 120 kWh up to 300 kWh 26 yen 90 sen × 180 kWh = 4,842 yen 00 sen    
Consumption past 300 kWh 28 yen 98 sen × 10 kWh = 289 yen 80 sen    
Total 7,267 yen 50 sen (2)  
Fuel cost adjustment amount △△△ yen △△ sen + △△ sen × (310 kWh - 15 kWh) = △△△ yen △△ sen (3)  
Renewable energy power generation promotion surcharge □□ yen □□ sen + ■■ sen (310 kWh - 15 kWh) = ◇◇◇ yen (4)  
Automatic transfer discount 54 yen 00 sen (5)  
Prompt payment (1) + (2) + (3) + (4) + (5) = ○,○○○ yen (6) Rounded down to nearest yen
Prompt payment above includes:
Money for consumption tax, etc.
(7) × 8/108 = ●●● yen   Rounded down to nearest yen

The bill amount in the above calculation example is for prompt payment and when fuel cost adjustment is not implemented. (Where fuel cost adjustment is implemented the fuel cost adjustment amount will be added or subtracted.)
