- The unit price includes the equivalent of consumption tax, etc.
- "Spring/Autumn" refers to the periods from March 1st to June 30th and October 1st to November 30th, and "Summer/Winter" refers to all other periods.
- The contracted power will be between 0.5kW and 50kW.
- The contract award method will be based on actual quantity.
- Bank transfer discount (55 yen discount per month) does not apply.
- This offer is for customers who use an EcoCute water heater, a storage battery, or an electric vehicle, and who can switch their electricity usage to "Sunshine Time" using the relevant equipment.
- Customers who own solar power generation systems may experience a decrease in electricity sales revenue due to the shift of load from "EcoCute," "storage batteries," and "electric vehicles" to "Ohisama Time." Therefore, depending on your contract details and electricity usage, your actual electricity bill may not be more advantageous even if the calculations suggest it would be.
- In addition to Base charge and Power usage charge, the electricity rate also includes a fuel cost adjustment and Renewable Energy Generation Promotion Surcharge. Because there is no upper limit to the fuel cost adjustment applied to the Ohisama Hirutoku Plan, in the event of a sharp rise in fuel prices, the fuel cost adjustment amount may be higher for the Ohisama Hirutoku Plan compared to Rate Plan that have an upper limit for fuel cost adjustment (such as Residential lighting B). Therefore, depending on the customer's contract status and electricity usage, etc., the actual electricity rate may not be more cost-effective if you subscribe to the Ohisama Hirutoku Plan, even if the estimated cost adjustment amount is not taken into account.
The contracted power is determined based on the actual power usage (maximum power usage) of the customer. The contracted power for each month is the greater of the maximum power usage for that month and the maximum power usage for the previous 11 months, as measured by the smart meter.
