Essentials Issues for Saving Energy
Target Value Management
Managing objectives is a very important issue when practicing energy savings.
“Target value management” is the process of transforming actual conditions into ideal conditions, and thereby requires
understanding the actual situation and how much “unseen” waste there is. For this reason, target value management
involves performing detailed management of operations, moving from months to days and lines to equipment, and evolving
from “seeing” waste to “understanding” it.
Additionally, when using target value management, it is necessary to construct and put into practice an organization that
values “people who set objectives (manage),” “people who find things” and “people capable of thinking of improvements
and implementing them.”

Target Value Management

Monthly Daily

Specific consumption management

In lines where there is a large difference in production volume, it is difficult to save energy and improve productivity using
energy management alone.
By understanding specific consumption —energy consumed per product— waste in energy and production processes can
be clarified, and it becomes easier to implement countermeasures.
Rather than simply not using energy, it’s important to use energy efficiently when, where and how much needed.

Specific consumption management

EM (Energy loss Minimum) activities
• No-load power is consumed when there is no production.
Actual • Lights are on in areas where there are no people.
• There are no inverters, so an unnecessary amount of energy is being used.

This is Improvements Discover waste

specific consumption
management

Energy required for production:

• Necessary time (year, month, day, hour, minute, second...)
Ideal • Necessary place (all, building, department, production line, equipment)
• Necessary amount (technical standards, use/operation standards)

Improve productivity ( ➔ Save energy)

The ideal condition is efficient use of the necessary amount of energy, at the necessary place and necessary time.

Importance of Demand Monitoring

Energy Saving by visualizing demand
What is “Demand”....?
Demand is average electric power at a specified period. This period for demand differs for each country and the way of
management method.
Electric fee is basically determined based on the highest demand in one year(→contract demand).
The higher contract demand is, the more expensive the electric basic charge.
There are two types of basic demand management method as below.
(1) Fixed block demand management method (2) Rolling block demand management method
The demand period consists of only an interval. The demand period consists of interval and sub interval.
Interval is the period for caluclation of average electric.
Sub interval is the period for updata the calculation.
Fixed block demand management Rolling block demand management method
Ex) Interval：30min Ex) Interval：15min、Sub interval 5min

EcoWebServer# with demand monitoring function comply with the Fixed block
demand management method. Interval can be selected from 15min or 30min or 1hour.

Subtotal Volume
• Demand (power demand) is computed and calculated by taking
pulses from the multi-measuring meter
(transaction meter) for power demand.
* In the case fixed block demand
management.
Estimation
• The value at the end of the 30-minute time limit is estimated Reduce
from the measured demand (power demand).
demand
Warning
• Based on the results of the estimation, an alarm is output and a
notification sent when the objective demand has been exceeded.
• The alarm notification can be a buzzer, display lamp, etc., which
is sent through the contact output. Reduce

Load interruption
• Load interruption may be necessary depending on power use.
• A control output signal can be used to automatically interrupt
the load.
