6. Streamlining of conversion of electricity into power, heat, etc.

6-1 Electrical facilities and electric heating facilities, etc.
(1) Management of electrical facilities and electric heating facilities, etc.
1. For electromotive power application facilities, management standards shall be implemented accounting for relationship with initial power to minimize electrical loss due to idle operation of motors, and operation shall be suspended when not required.
2. For multiple motors, management standards shall be implemented to maintain the demand factor of each motor appropriately, and the number of units in operation and load shall be allocated appropriately.
3. For fluid-associated machinery such as pumps, fans, blowers, and compressors, management standards shall be implemented, and delivery feed and pressure shall be adjusted appropriately and motor load minimized through control of number of units, change of speed, change of piping, impeller reduction, and control of speed based on revisions in pressure and discharge on the side of use.
4. Management standards shall be implemented for the electric heating facilities of induction furnaces, arc furnaces, resistance furnaces, etc., to maximize thermal efficiency by improving heated object loading, reducing electrical loss due to no-load operation, using heat insulation and recovered waste heat (confined to facilities exhausting gas).
5. Electrodes of appropriate shape and features shall be used for electrolysis facilities, and items including the distance between electrodes, electrolyte concentration and contact resistance of the conductor shall be appropriately managed by implementing management standards to improve electrolytic efficiency.
6. Use of electric power shall be managed based on management standards implemented for voltage, current, etc., required for reducing electrical loss for each electrical facility, such as electrical facilities and electric heating facilities, etc.

(2) Measurement and recording of matters for electrical facilities and electrical heating facilities, etc.
- For facilities such as electrical facilities and electrical heating facilities, management standards shall be implemented for measuring and recording voltage, current etc., required for reducing electrical loss, and such matters shall be regularly measured and results recorded based on standards.

(3) Maintenance and inspection of electrical facilities and electrical heating facilities, etc.
1. For electrical facilities, management standards shall be implemented for maintenance and inspection to minimize the mechanical loss of load machinery, defined as machinery comprising the load of electrical motors, drive train parts and electrical motors, and regular maintenance and inspection shall be conducted based on standards.
2. For pumps, fans, blowers, compressors, and other fluid-associated machinery, management standards shall be implemented for maintenance and inspection to prevent leakage of fluid-associated and minimize the resistance of pipes transporting fluid-associated, and regular maintenance and inspection shall be conducted based on standards.
3. For electrical heating facilities and electrolysis facilities, management standards shall be implemented for maintenance and inspection to minimize the resistance loss of parts such as wiring connections and switch connections, and regular maintenance and inspection shall be conducted based on standards.

(4) Measures for new installation of electrical facilities
- For installing new electrical facilities expected to be used under during constant large load fluctuation, facilities shall be configured to enable operation to be easily adjusted based on load fluctuations.
