Tokyo Electric Power Company Holdings plans to increase electricity rates for corporations starting April usage, due to soaring crude oil prices. The company will revise its calculation method to reflect the previous month's fuel prices. Household rates will not see the impact until June at the earliest.
Tokyo Electric Power Company Holdings, Inc. (TEPCO) is set to raise electricity rates for corporations effective April 2026 usage, in response to soaring crude oil prices. The utility plans to update the calculation method for corporate rates, shifting from a three-month average of fuel prices from three to five months prior to directly incorporating the previous month's fuel price.
Electricity prices are adjusted in line with fluctuations in fuel costs, such as crude oil and liquefied natural gas. This change ensures that the current surge in crude oil prices is promptly passed on to corporate customers. For household rates, however, the reflection timing remains unchanged, meaning the price increase will not appear in residential bills until at least June.
TEPCO's move addresses the rising fuel expenses, with corporate users facing the adjustment first.
