Customer Communication
Monthly electricity rates are the sum of demand charge and energy charge plus the consumption tax, etc. Demand charge will be determined by the contract ampere or contract power, while the energy charge will be calculated according to energy consumption.
The energy charge to be adjusted under the fuel cost adjustment system*, however, will be the sum plus or minus the fuel cost adjustment amount.
* The fuel cost adjustment system is designed to meet changes in recent fuel costs, so that electricity rates will be adjusted automatically every three months according to certain standards if the cost of fuels, such as crude oil, LNG (liquefied natural gas), or coal, rises or falls due to fluctuations in the foreign exchange rate and energy prices.
A residential customer's contract will be classified as Meter-Rate Lighting
B or C.
A contract ampere will be determined according to the size of an electric current (ampere) used by a customer. In this case, the ampere breaker will be installed in a customer's home so that the current will be cut off automatically if electricity is used beyond the contract ampere.
Your present contract ampere is distinguished by the color of the ampere breaker.
| Contract ampere | 10A | 15A | 20A | 30A | 40A | 50A | 60A |
|---|---|---|---|---|---|---|---|
| Demand charge | ¥273.00 | ¥409.50 | ¥546.00 | ¥819.00 | ¥1,092.00 | ¥1,365.00 | ¥1,638.00 |
[ How to change your contract ampere ]
To change or increase the present contract ampere, contact your nearest TEPCO
customer center and tell them your desired contract ampere. A TEPCO service
staff will visit your home on an appointed day and change the ampere breaker.
The ampere breaker can be replaced free of charge.
Meter-Rate Lighting C
A contract ampere will be determined according to the volt-ampere of a main
circuit breaker installed at a customer's home or the number of branch circuits.
Payment Term
You are requested to pay your electricity bill within 30 days from the day your
meter is read. If failure of payment exceeds 50 days, the electricity in your
home may be stopped as stated in a prior notice.
Overdue Payment
If the last payment day has passed and you fail to pay your electricity bill,
we may charge overdue interest on the days following the payment date to
the day on which you pay the bill. The overdue interest shall be a sum
determined by multiplying the net charge for payment covered by the calculation
of such interest by 10% per annum (for the purpose of such calculation, all
years, including leap years, shall be considered to have 365 days each).
Rate of Meter-Rate Lighting (Monthly)
Under Meter-Rate Lighting, the energy charge is divided into three blocks
so that a higher rate will apply as energy consumption increases.
