Result of Observation

• A few of Customer still not care about saving energy. The lamps and equipments still “on” although are not needed.

• Average switching design of the building still using centralize system.

• Many of the customer still using the old lamp that not save energy.

• The uncontrollable equipment still not use auto switching as timer switch to optimize consumption.

Who Responsible ??• PLN

• Customers

• Government

• Producer/manufacture

Saving Energy depends on:

• Habit or attitude

• Design

• Equipment

SAVING TO BURN FUEL

RP. 1 MILYAR/DAY

Easy Steps To Save Energy

• Make commitment to all employees and people you meet.

• Replace all the old lamps with new product by the energy saving lamp.

• Redesign of centralize switching system become partial system.

• Use “timer switching” of all equipment that is not controllable.

• Reduce and shift consumption on the peak load time (17.00 – 22.00 Wita)

Energy Saving Tips

• Turn off your lamps and equipments that are not needed.

• Adjust temperature degree in your freezer depends on capacity.

• Adjust AC temperature with room degree (25 C)• Make sure all of equipments at “off” position (not

stand by) when we do not use and don’t stop only by using remote control.

• Choose lamp and all equipments which can save energy.

• Avoid iron, rice cooker, water pump and other at peak load time (17.00-22.00)

Demand Side Management

Avoid using electricity when they are nor needed

Choose the saving energy lamp

Avoid using iron, rice cooker, water pump at 17.00 -22.00

Reduce only 50 watt 17.00 – 22.00

Operate Genset (Emergency Unit) at 17.00 – 22.00

Multiple effects of saving energy

• For internal, Saving energy means reducing cost and efficiency.

• Care and contribute to keep sustainable and continuity electricity supply.

• For Nation, it means helping “Load of Subsidy”.• It means helping Nation to keep “Devisa”,

because they do not import the Fuel • It means reducing to burn fuel which same as

reducing CO2 emission, so that, we care about global warming.

Advise

• Mr. Gde Prama said about “3-S Principle” that starts from Saya (Myself), Sekarang (Now) and Sederhana (Simple).

• The Earth is not the ancestors’ inheritance but deposit for descendants.

Conclusion

• Growth of electricity supply and electricity demand is not balance, go to crisis condition.

• The Energy Primer is limited and will finish

• PLN avoids to use fuel consumption and shift to renewable energy

• All customers must know about this crisis and save energy every time
