Peak demand is calculated by first breaking up customer usage into 30-minute increments and then choosing the increment that has the highest value over a one-month period.
This value increases due to simultaneous electric facility usage.
For 500kW power contract customers, the power contract value will be the peak demand from the past year including the present month.
Therefore, contracted power will increase in concert with peak demand.
Basic charges are calculated based on the value of the power contract, so reducing the peak demand causes a reduction in demand charges.
The Demand Control System is a system whereby the inhibition of peak demand reduces the power contract based on the customer's own actions in setting the target value and controlling electric facility usage.
*The result is not ensured.
The Demand control system monitors the use of power and records and manages the demand value.
There are 2 types of controlling systems: one manual and one automatic.
- Manual-control Type (Alarm type)
-
When power usage becomes close to exceeding the target set in advance, the system will set off an alert alarm.
*Electric facilities (air conditioner / lighting) will be controlled by the customer manually
- Automatic-control Type
-
A system that automatically controls the electric facilities. Based on the preset prioritization of the electric facilities, the system will automatically control and issue out alarm alerts so that the designated target will not be exceeded.
