June 29, 2023

TEPCO Energy Partner, Inc.

In response to today's announcement of the fuel prices from March 2023 to May 2023 (prices of crude oil, LNG, and coal according to trade statistics), the fuel cost adjustment unit prices and the fuel cost, etc. adjustment unit prices included in the electricity rates for August 2023 have been determined as follows.

1. For low-voltage supply customers: Fuel cost adjustment unit prices (including tax)

For low-voltage supply customers: Fuel cost adjustment unit prices (including tax)

Low-voltage electricity rates will be determined by taking into account the fuel cost adjustment price, which changes every month, the renewable energy power promotion surcharge, which is newly set each fiscal year, and the nationwide electricity rate mitigation measure (sharp fluctuation mitigation measure). For details, please refer to Attachment 3.

2. For high-voltage/extra high-voltage supply customers: Fuel cost, etc. adjustment unit prices and fuel cost adjustment unit prices (including tax)
The fuel cost, etc. adjustment unit prices took effect on April 1, 2023 for customers whose contracts expired during the period from December 31, 2022 to March 31, 2023.
In addition, these prices will apply to the subsequent contract period for customers whose contracts expire on or after April 1, 2023.

*1 Kanto Area: Tochigi Prefecture, Gunma Prefecture, Ibaraki Prefecture, Saitama Prefecture, Chiba Prefecture, Tokyo Metropolitan Area, Kanagawa Prefecture, Yamanashi Prefecture and Shizuoka Prefecture (east of Fujikawa)
*2 Rate plans before the full liberalization of the electricity market (excluding optional agreements) such as Meter-Rate Lighting, Low-Voltage Electricity, etc.
*3 Rate plans after the full liberalization of the electricity market such as Standard Plan, Premium Plan, Smart Life Plan, Power Plan, etc., and optional agreements such as Denka Jozu
*4 A consumption tax and other costs are included in the prices.
*5 August 2023 rates (July consumption. However, this correlates to August consumption for high-voltage supply contracts for which meters are read on the first day of each month) include unit price discounts (low-voltage supply: 7.00 yen/kWh, high-voltage supply: 3.50 yen/kWh) as a nationwide measure for mitigating sharp fluctuations in electricity rates. However, these measures do not apply to extra high-voltage supply contracts. For further details, please refer to the page on our website dedicated to this topic (in Japanese only). Please note that August 2023 rates correlate to consumption during the period from when the meter is read (or measurement date) in July 2023 to the day before the meter is read (or measurement date) in August 2023. However, for high-voltage supply contracts for which meters are read on the first day of each month, this correlates to consumption during the period from August 1, 2023 to the last day of August, 2023.
