In light of changes in the supply and demand structure, in order for us to continue to provide a stable supply of electricity to our customers, we will be reviewing electricity rates for some low-voltage Rate Plan (former all-electric menus, etc.) from April 1, 2025. (Announced on November 28, 2024)
In order to achieve carbon neutrality, we have been working to proactively introduce renewable energy, including solar power generation. As a result, on the supply side, the proportion of electricity generated by renewable energy sources is increasing, especially during the daytime, while on the demand side, the way electricity is used throughout the day is changing significantly due to the expansion of Private consumption of solar power generation and the progress of energy conservation and electrification.
We have decided to review our electricity rates in order to respond to these changes in the supply and demand structure and continue to provide a stable supply of electricity to our customers.
- The total power demand over 24 hours is set to 100%, and the ratio for each time period is graphed.

Lighting by Season & Time-of- Use, Lighting by Time Slot, Lighting in Peak Shifts, High-Load Lighting Plan,
Low- Voltage Seasonal Power Plan, Late Night Power A, Late Night Power B, Secondary Late Night Power,
Low-voltage thermal storage adjustment contract
- We stopped accepting new applications for Lighting by Season & Time-of- Use, Lighting by Time Slot, Lighting in Peak Shifts, Late Night Power A, Late Night Power B, Secondary Late Night Power, and Low-voltage thermal storage adjustment contracts in April 2016, but customers who had contracts at that time will continue to be under their contracts.
- You can check your contract rate menu on your monthly meter reading slip or through our member service "My Kyuden."

In light of changes in the supply and demand structure, we will review the nighttime Power usage charge and heat storage rate for the applicable menus. In addition, for Lighting by Season & Time-of- Use, we will also review the daytime and Personal time Power usage charge rate. (Please see the rate unit prices before and after the review for the rate unit prices that will be applied from April 1, 2025.)
supply conditions and guidelines reflecting the revised content (to be implemented on April 1, 2025) can be viewed by downloading Terms and Conditions of Electricity Supply and Terms and Conditions of Supply and Demand Contract, etc.
If you would like to know the impact of the rate review or the optimal plan after the review, you can make estimates using the electricity rate simulator on our membership service "My Kyuden."
If, based on the results of the calculations, you would like to change your plan to the optimal menu, you can apply using the form below.
April 1, 2025
- Up to March 31, 2025 and after April 1, 2025, the calculation will be made on a pro rata basis based on Old rate.
If you have any questions about the fee review in April 2025, please refer to the "Frequently Asked Questions" section.
