How to Calculate Your Electricity Bill
Monthly electricity rates are the sum of the demand charge, energy charge, Renewable Energy Power Promotion Surcharge*1 and the Photovoltaic Power Promotion Surcharge ("PV surcharge")*2, etc. The demand charge will be determined by the contracted ampere or contracted power, while the energy charge will be calculated according to the amount of energy consumption.
The energy charge to be adjusted under the fuel cost adjustment system*3, however, it will be the sum plus or minus the fuel cost adjustment amount.

1*The "Renewable Energy Power Promotion Surcharge" is calculated based on the "unit price of Renewable Energy Power Promotion Surcharge" set every fiscal year according to provisions; such as the "Act on Purchase of Renewable Energy Sourced Electricity by Electric Utilities", and will be added to the customer's monthly electricity bill.
2* Under the Excess Electricity Purchasing Scheme for photovoltaic power, the total amount TEPCO pays to a residential renewable energy generator will be passed on to all electricity users as a "PV surcharge".
3* The fuel cost adjustment system is designed to meet changes in recent fuel costs, so that electricity rates will be adjusted automatically every month 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.

Information about Your Electricity Supply Service Contract
A residential customer contract will be classified as Meter-Rate Lighting B or C.

Press Release (Jan 14,2014)Notification of Changes to General Supply Provisions

Meter-Rate Lighting B
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 contacted ampere is represented by the color of the ampere breaker.

[ 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.

img08 Overdue Payment
If failure to pay your electricity bill exceeds your last payment day, we may apply overdue interest to the number of days following the due payment date to the date autual payment is made. The overdue interest shall be the sum determined by multiplying the net charge for payment covered by the calculation of such interest by 10% per annum (for calculation purposes, all years, including leap years, shall be treated as having 365 days).

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.
