1 EET432 ELECTRICAL ENERGY UTILIZATION CHAPTER 5: SUSTAINABLE ENERGY MANAGEMENT SYSTEM By TUNKU MUHAMMAD NIZAR BIN TUNKU MANSUR P.ENG. (BEM), REEM (ST), CEM (AEMAS)

2 ENERGY MANAGEMENT (EM) Process of managing energy consumption in the organization to assure the energy is been efficiently used. Covers all aspects of energy consumption in the organization, technical and non-technical. Not only machines and equipments but also best practice from the operator. 2

3 PRINCIPLE OF EM Comply with organization goals and objectives. Able to raise staff awareness and get involvement from them. Develop organization and staff knowledge. Support continuous improvement process. Able to integrate with standard operating procedures and other quality systems in the organization. 3

4 BENEFIT OF IMPLEMENTING EM Setting up systematic energy cost management to achieve energy saving. Reducing operation and maintenance costs. Increasing staff awareness for energy conservation and waste minimization. Developing staff knowledge and organization on energy management. Setting up an energy target and plan. Comply with regulation. Recognition and award. 4

5 ENERGY COST CYCLE Without SEMS, the organization will not be able to control and maintain the saving. Once the focus is moved, energy cost will go up again. A SEMS will help the organization to control the energy reduction and maintain the resultant saving. 5

6 AEMAS ENERGY MANAGEMENT GOLD STANDARD (EMGS) AEMAS is the world s first regional certification system for energy managers and energy end-users and is adopted by the Malaysian Green Technology Corporation (MGTC) under Ministry of Energy, Green Technology and Water (KeTTHA). It is funded by the European Union under the Switch-Asia Programme, it is currently being implemented by the ASEAN Centre for Energy in eight (8) ASEAN Member States (Cambodia, Indonesia, Laos, Malaysia, Myanmar, Philippines, Thailand and Vietnam) The Energy Management Gold Standard (EMGS) is the brand of excellence for sustainable energy management system awarded to companies/organizations as certified by AEMAS. It has 3 level of certification, namely: 1 star, 2 star and 3 star. 6

20 ENERGY MANAGEMENT COMMITTEE Key player / working team to implement the energy management action plans agreed by the whole organization. Some of the duties: Assess energy management performance Analyze organization s strength and weakness Prepare energy policy for the organization Organize the preparation of the working procedures, working manuals and tools. Prepare energy target and plan Monitor the implementation of the energy management system Review and adjust the energy, target and plan for continuous improvement. 20

21 ENERGY MANAGEMENT COMMITTEE Energy Management Committee should have both technical and management representatives. Have enough technical knowledge within the group to either understand the technology used by the organization, or be trainable in that technology. Have a knowledge of potential new technology that may be applicable to the program. Understand the economic evaluation system used by the organization, particularly payback and life cycle cost analysis. Have good communication and motivational skills since energy management involves everyone within the organization. 21

22 EXAMPLE OF EM COMMITTEE 22

23 ENERGY ACCOUNTING CENTRE (EAC) Energy has been consumed in all parts of the organization hence it is quite difficult to manage and control energy consumption at macro level. Therefore the Committee should divided the organization into small division called Energy Accounting Centre (EAC) to effectively control the energy consumed. Each EAC will be monitored by a person-in-charge to be responsible for energy consumption in each EAC s. The usual way to divide the organization is through department or line process. 23

25 EXAMPLE OF EAC 25

26 OTHER EM COMPONENTS Energy Management Committee should establish standard working procedures for the Energy Management System. In addition, it should includes the operational guidelines, maintenance procedure and checklist for equipments such as working procedure for air compressor, air-conditioning, lightings, pumps and motors. Establishing energy saving target and setting action plan. Conducting awareness training and campaign toward energy saving is important to get active participation from all staffs towards the energy efficiency initiatives and energy conservation activities to ensure successful of the programs. 26

27 SETTING TARGET 27

28 SETTING TARGET 28

29 APPROACH FOR EM ACTIVITIES No Cost Energy Saving Approach - Targeting less than 5% of electrical energy saving Low Cost Energy Saving Approach - Targeting between 5% - 20% of electrical energy saving Medium / High Cost Energy Saving Approach - Targeting more than 20% of electrical energy saving 29

30 APPROACH FOR EM ACTIVITIES No Cost Energy Saving Approach Shutting down equipments when not in used. The usage of high power equipment must be controlled. More toward awareness. Low Cost Energy Saving Approach Replacing equipments with high efficiency low power consumption. Use of timer or zone control for lighting Maintenance of equipments must be in scheduled. Improving power factor The usage of high power equipment must be controlled. Need management commitment. 30

31 APPROACH FOR EM ACTIVITIES Medium / High Cost Energy Saving Approach Reviewing the process involved. Recommendation from Investment Grade Audit (IGA) Implementing from design stage. Improving power factor Replacing equipments with high efficiency low power consumption. Use Energy Performance Contracting (EPC) mechanism Need management commitment. 31
