    1. TECHNICAL WORKING GROUP III : Energy Efficiency Master Plan Hotel Grand Candi, 10-11 July 2011

    2. Background Energy has a very important role and become a basic necessity in national sustainable development. Therefore, energy should be used sparingly, rational, and wisely so that the energy needs in the present and the future can be met.

    3. Background If the policy to conserve energy, encourage use of renewable energy and carbon emission reduction is adopted, the energy requirement would be reduced by 12-16 percent.

    4. Background Presidential Instruction No. 9 of 1982 . The steps of energy conservation through: a) The energy-saving campaignb) Training of conservationc) Demonstration and examples of energy-efficient appliancesd) conservation technology R & De) Development of energy audit, identify potential efficiency improvements f) Standardization

    5. HOUSEHOLD CURENT SITUATION OF ENERGY CENTRAL JAVA PROVINCE BUSINESS SECTOR FOR EFFICIENCY INDUSTRY

    6. Comparison of Number of Subscribers Household Sector, Business and Industry

    7. Electricity price comparison of Household Electrical Sector, Business and Industry

    8. Comparison of the time blazing Household Sector, Business and Industry

    9. PLAN TARGET OF ENERGY EFFICIENCY The details and profile of energy use in the household sector, industrial, and commercial buildings in Central Java. 1 Identification of energy waste and potential savings in the household sector, industrial and commercial buildings. 2 Recommendations of energy saving measures. 3 4 The priority or order of application of energy conservation based on the technical, financial and environmental. The feasibility study recommended Energy Conservation Projects which require a fee (medium / high cost). 5

    10. ENERGY CONSERVATION NATIONAL POLICY Presiden Instruction No. 9 Year 1982 in Energy Conservation 1982 Presidential Decree No. 43 Year 1991 in Energy Conservation 1991 Master Plan in National Energy Conservation Year 1995 (Ministrial Decree No. 100/48/M.PE/1995) and revised in year 2005 1995 ENERGY CONSERVATION POLICY Law No. 28 Year 2002 in buildings 2002 Presiden Instruction No. 10 Year 2005 in Energy Eficiency and MESDM regulation No. 0031 Year 2005 in Energy Efficiency Procedure. 2005 Presiden Regulation No. 5 Year 2006 in National Energy Policy 2006 2007 Law No. 30 Year 2007 Energy Presiden Instruction No. 2 Year 2008 in Energy and Water Efficiency 2008 2009 Government Regulation No.70 Year 2009 Energy Conservation

    11. L E G A L B A S IS Regional Regulation and Policy Efficiency Local Government / State 1 2 3 4 5 Develop plans based electrical energy needs of efficiency. (Distric) Provide energy conservation information dissemination, such as campaigns, training, seminars workshops, and pilot. Provide incentives related to energy conservation activities, such as providing investment incentives and awards for energy conservation. Impose energy conservation standards, such as SNI Energy Conservation in buildings in the law and licensing. Make regulations requiring the implementation of energy conservation to companies or industries, such as legislation, regulations regarding licensing in all sectors. Efficient and Saving in Energy Usage

    12. Action Plan for Energy Efficiency Low cost or no cost by immediate action with a payback 1 year ACTION PLAN FOR TECHNICAL Investment plan for the medium-term measures with a payback period of 1-5 years. Long-term strategy (eg. awareness campaign).

    13. Step Implementation of Energy Efficiency Awareness and Education Campaign Training Education Pilot Project Dialog Forum Multi Sector Controlling Energy Audit Energy Management Standardization Procurement Inisiative Insentif Fiscal Insentive Subsidy diversion Appreciation Market transformation Partnership Procurement Initiative

    14. HOUSEHOLD SECTOR No Cost. By turning off 2 bulbs in specific time (ex: 5pm – 10pm). Bulb has 60 Watts, every house can saves 600 watts.

    15. in one month, every house can save : = Rp. 15.435,- Everymonth saving Rp. 15.435,- x 6002195 = Rp. 92.643.879.830 It saves up to 108 GW

    16. HOUSEHOLD SECTOR (investment plan) We are targeting people who want to change the light bulbs into energy saving lamps is 20%. Active time ± 5 hours.

    17. Total Household Customer

    18. For three classes (450, 900, 1300 VA) Save: 20,7 kWh For the one month: With the light bulb uses = 27 kWh With energy saver bulbs = 6,3 kWh 450 VA = 20,7 x 790 x 495 x 3.980.991 = 13.020.229.164,60 900 VA = 5.539.794.609,60 1300VA = 704.892.794,40 Total saving cost = Rp. 19.264.916.568,60

    19. For three category (450, 900, 1300 VA) For the second month and so on we just need to accumulate of the total saving cost per month. With investment for three category is Rp. 35.000,- x total household customer x 20% = 41.232.317.000,00 / month So NPV can be found as shown in the graphic:

    20. For three classes (450, 900, 1300 VA) We can see that the payback will be got after almost only two-half months.

    21. Replacement the refrigerator For general, the old refrigerator: 0,15 kW the new ones: 0,07 kW (single door) Using time is 24 hours and discount rate 12% / year. BEFORE : acc. Energy/month = 0,15 x 24 x 30 days = 108 acc. Energy cost = 108 x Rp 495,- = Rp. 53.460,- With IRR= 0,99 << , DR = 0,01 Monthly cost = (IRR x DR x acc. Energy cost) = Rp. 52.930,69 AFTER : Rp. 22.936,63

    22. Replacement the refrigerator

    23. Replacement the refrigerator Energy cost saving = Rp. 29.994,06 PER MONTH With the investment to buy new refrigerator is Rp. 1.000.000,- The payback is after 60 month or five year.

    24. PLN’s benefit

    25. Business Sector • Increasing the awareness of costumer’s electrical usage • Replacing the conventional tools with the energy saving one

    26. TIME MANAGING According to survey in a hotel in Central Java, because of time managing, this hotel can save the price up to Rp 62,927.44 a day. It mean, in 1 month, that hotel can save up to Rp.188,782.32. If all hotel in Central Java (106 star hotels) organize a usage of its electrical tools, hotel business in Central Java can save money up to Rp 20 million/month. Just imagine, there’s 1090 not starred hotels in Central Java.

    27. Replacing conventional bulbs to energy saving bulbs With the same calculation with the household, for replacing 20 lamps, we get chart as below:

    28. Replacing solar-fuel boiler with heat exchanger Comparison solar-fuel boiler with heat exchanger

    29. Replacing solar-fuel boiler with heat exchanger From the data above, it can be concluded that the boiler using additional cost per month as a fuel, while the heat exchanger is not. From the data above obtained calculation results that by replacing the heat exchanger obtained BEP (Break Event Point) in the next 11 months from the time of initial purchase.

    30. Industrial Sector The main factors of energy optimization are as follows: • Settings "on time", just as long as needed only. • Modifications at the time, detector occupancy, building automation systems, and so on. • Optimal speed settings.

    31. Case Study InPT PANCAMANUNGGAL WIRADINAMIKA SEMARANG. 70%

    32. 18,5 kW 15 kW 11 kW ENERGY SAVINGOVER-SIZE DESIGN = 12,5 kW ACTUAL = 12,5 kW x SAFETY FACTOR = 12,5 kW x 1,3 = 16,25 kW OPTIONAL = 18,5 kW

    33. ENERGY SAVINGOVER-SIZE SAVING : - REPLACEMENT MOTOR = 18,5 kW - 15 kW = 3,5 kW - INSTALLATION VARIABLE SPEED DRIVE = 18,5 kW - 12,5 kW = 6 kW VARIABLE SPEED DRIVE WILL USE ENERGY ACCORDING TO THE LOAD CAPACITY NEEDS.

    34. ENERGY SAVINGOVER-SIZE

    35. ENERGY SAVINGOVER-SIZE

    36. ENERGY SAVINGOVER-SIZE The savings on motor done with the installation of temperature sensors and the installation of variable speed drives. Variable speed drives will use energy according to the capacity needs of the load by regulating the speed of the fan motor.

    37. ENERGY SAVINGSPEED vs ENERGY

    38. APPLYING THE PRINCIPLES: SPEED ≈ FLOW ≈ (PRESSURE)2 ≈ (ENERGY)3 0,9 SPEED ≈ 0,9 FLOW ≈ (0,9)2 ≈ 0.81 PRESSURE ≈ (0,9)3 ≈ 0,729 ENERGY • REDUCTION OF SPEED 10 % • SAVE ENERGY 27,1 %
