*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 Calculated based on the average fuel price of 66,300 yen/kl because the average fuel price exceeded the maximum price (66,300 yen/kl)
*6 May 2023 rates (April consumption. However, this correlates to May 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 May 2023 rates correlate to consumption during the period from when the meter is read (or measurement date) in April 2023 to the day before the meter is read (or measurement date) in May 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 May1, 2023 to the last day of May, 2023.
