Fuel Consumption + 1,4 Million Liter / day Electricity Power Supply for Bali: PLTD Pesanggaran 152 MW PLTG Gilimanuk 130 MW HSD PLTGU Pemaron 80 MW Transfer from Java via cable 200 MW 65% electricity in Bali use Fuel (HSD) Electricity Consumption in Bali is 6.452 MWh per day (Data th 2007) By Assumption 1 Liter HSD = 3 kWh, so each day we use and burn HSD almost : 65% x 6.452.000 kWh = 1.398.000 Liter 3 + 1,4 Million Liter / day If the price of HSD for Industries Rp. 9.000,-/Liter, it means each day same as Rp. 12,6 Billion.

Budgeting Cost of Production Cost of generate = Rp. 3.322 / kWh Cost of distribution = Rp. 304 / kWh Cost of Services = Rp. 45 / kWh COP (Cost of Production) = Rp. 3.671 / kWh Average Sales price (Subsidy) = Rp. 600 / kWh Defisit HSD/Solar price = Rp. 9.000 / Ltr Cost of transport = Rp. 665 / Ltr Total price for fuel = Rp. 9.665 / Ltr SFC = 0,3 Liter/KWH → = 0,3 x Rp. 9.665 = Rp. 3.322 / KWH (excluded cost of operator, maintenance and oil engine)

Portion of Consumption

Comparison of Consumption & Customers

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

REDUCE ONLY 50 WATT EVERY TIME 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 1 Avoid using electricity when they are nor needed 2 Choose the saving energy lamp 3 Avoid using iron, rice cooker, water pump at 17.00 -22.00 4 Reduce only 50 watt 17.00 – 22.00 Operate Genset (Emergency Unit) at 17.00 – 22.00 5

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
