Audit Energi Listrik Oleh: Dr. Giri Wiyono, M.T. Jurusan Pendidikan Teknik Elektro, Fakultas Teknik Universitas Negeri Yogyakarta giriwiyono@uny.ac.id Audit Ene rgi (Ene rgy Audit )Energy Conservation Energy Efficiency Energy Management Energy Audit Energy Conservation Free Encyclopedia):Efforts to reduce energy consumption through the result of several processes or developments, such as productivity increase or technological progress. Energy Efficiency Free Encyclopedia):The goal of efforts to reduce the amount of energy required to provide products and services. It is achieved when energy intensity in a specific product, process or area of production or consumption is reduced without affecting output, consumption or comfort levels. Sometimes called efficient energy use. Energy Management (1) Energy Management is a technical and management function the remit of which is to monitor, record, analyze, critically examine, alter and control energy flows through system so that energy is utilized with maximum efficiency. Paul O’Callaghan, Energy Management) Energy Management (2) The strategy of adjusting and optimizing energy, using systems and procedures so as to reduce energy requirements per unit of output while holding constant or reducing total costs of producing the output from these systems Bureau of Energy Efficiency, India) Energy Audit (1) Free Encyclopedia) An energy audit is an inspection, survey and analysis of energy flows for energy conservation in a building, an industry, process or system to reduce the amount of energy input into the system without negatively affecting the output(s).Energy Audit (2) US Agency for International Development) Energy audit is a tool to identify areas where energy can be conserved. Energy Audit (3) Guide Book: Energy Audit) The verification, monitoring and analysis of use of energy including submission of technical report containing recommendations for improving energy efficiency with cost benefit analysis and an action plan to reduce energy consumption. Energy Audit (4) PP 70 tahun 2009 tentang Konservasi Energi) Audit Energi adalah proses evaluasi pemanfaatan energi dan identifikasi peluang penghematan energi serta rekomendasi peningkatan efisiensi pada pengguna energi dan pengguna sumber energi dalam rangka konservasi energi. Preliminary Energy Audit Preliminary energy audit is a relatively quick exercise to :Establish energy consumption in the organization Estimate the scope for saving Identify the most likely (and the easiest areas for attention) Identify immediate (especially no-cost/lowcost) improvements/savings Set a ‘reference point’ Identify areas for more detailed study/measurement Preliminary energy audit uses existing, or easily obtained data Detailed Energy Audit (1) A comprehensive audit provides a detailed energy project implementation plan for a facility, since it evaluates all major energy using systems. This type of audit offers the most accurate estimate of energy savings and cost. It considers the interactive effects of all projects, accounts for the energy use of all major equipment, and includes detailed energy cost saving calculations and project cost. Detailed Energy Audit (2) In a comprehensive audit, one of the key elements is the energy balance. This is based on an inventory of energy using systems, assumptions of current operating conditions and calculations of energy use. This estimated use is then compared to utility bill charges. Peraturan Pemerintah No. 70/2009 Pasal 12 Pemanfaatan energi oleh pengguna sumber energi dan pengguna energi wajib dilakukan secara hemat dan efisien. Pengguna sumber energi dan pengguna energi yang menggunakan sumber energi dan/atau energi lebih besar atau sama dengan 6.000 (enam ribu) setara ton minyak per tahun wajib melakukan konservasi energi melalui manajemen energi. Peraturan Pemerintah No. 70/2009 Pasal 12 Manajemen energi dilakukan dengan: menunjuk manajer energi; menyusun program konservasi energi; melaksanakan audit energi secara berkala; melaksanakan rekomendasi hasil audit energi; melaporkan pelaksanaan konservasi energi setiap tahun kepada Menteri, gubernur, atau bupati/walikota sesuai dengan kewenangannya masingmasing.
