Chamber of industry morang - Energy Efficiency

  1. 1. Chamber Of Industries, Morang Establishment : 1967 A.D ISO 9001:2001 Certified
  2. 2. INTRODUCTION Chamber of Industries Morang (CIM) is one of the leading chamber in Eastern Region. It was established in 2024 B.S. (1967 A.D) by one of the well-known Industrialist of Nepal with the aim of promoting Industries, develop national and International trade and commerce to achieve quality objectives, make necessary co- ordination with government and among Industrial sector. Chamber of Industries Morang plays a key role in promoting different activities like training, Workshop, Energy Conservation Program, Industrial trade fair, Seminar, Talk Programs and corporate social responsibilities.
  3. 3.  Mission Develop national and international business, coordinate and regulate different activities establishing cooperation among the industries of the region.  Vision Depicting proper industrial sector and encouraging industrialists and business personalities towards nation economic development.  Objective To promote member industries, develop national and international trade & commerce, to achieve quality objectives, make necessary co-ordination among industrial sectors. 1. To co-ordinate among organizations and federations. 2. To protect industrial rights for mutual helps among national, international and local authorities. 3. To analyze and suggest annual policies, rules, plans for related member industries. 4. To participate actively in any conflict among industries and labor problem. 5. To organize regional, national & International seminar, talk program & workshop. 6. To open branch offices in all over Nepal if required for the protection of industries. 7. To flow information to the associated members and secretariat.
  4. 4. ENERGY AUDIT An energy audit is an examination of an energy consuming equipment/system to ensure that energy is being used efficiently. (Or) “Energy Audit” means the verification, monitoring and analysis of the use of energy including submission of technical report containing recommendation for improving energy efficiency with cost benefit analysis and an action plan to reduce energy consumption.
  5. 5. Purposes of Energy Audit: 1. Find realistic energy saving. 2. Environmental protection. 3. National Energy supply/demand balance. 4. Occupational safety and health 5. Promoting energy efficiency and conservation. 6. Create important information, new ideas. 7. Define cost effective project. 8. Prepare action plans. 9. Develop staff training programs. 10.Aspiration of the improvement to corporate image by promoting energy efficiency and conservation
  6. 6.  Objective Energy audit is an effective energy management tools. By identifying and implementing the means to achieve energy efficiency & conservation, not only can save energy but also equipment/system life can be extended. All these means saving money. Based on the principle of “The less energy is consumed, the less fossil fuels will be burnt” so companies will generate relatively less pollutants and by- products. Therefore, all concerning these will contribute to conserve the environment and to enhance sustainable development. Environmental Protection Energy Audit = Saving Money + Sustainable Development
  7. 7. Classification Of Energy Conservation Measures Based on energy audit and analysis of the plant, a number of potential energy saving projects can be identified. These may be classified into three categories.  No cost/Low cost – High return  Medium cost- Medium return  High cost- High return Normally the low cost - high return projects receive priority. Other projects have to be analyzed, engineered and budgeted for implementation in a phased manner.

  17. 17. Benefit of Energy Cell  Morang & Sunsari Industrial load is about 45 MW, when energy conservation and audit was conducted it was found about 10% energy was saved. It can result in financial capital, environmental quality. Economic security and national security.  It will help to promote the concept and fundamentals of energy conservation so that Industries in this region as well as in Nepal can become more competitive.  To provide creative input into product and service innovation.  Present and Explain energy efficiency program to all sector of economy.  To promote energy awareness in Eastern region with coordination with sister organization.
  18. 18. How Energy Cell will serve to Industries 1. Data collection and Analysis.  Comparison with standard /Industrial best, average.  Production data for industrial plants to find out operation improvement opportunities. 2. Site Investigation  Discuss operation with site personnel, often they will know the energy use problems.  Install energy monitoring where required to assess opportunities and to identify energy waste. 3. Cost and Benefit Analysis when conducting  Feasibility study on energy saving projects cost and benefit analysis are essential
  19. 19. Cont.… 4. Preparation of concise report. 5. Staff training  Through Energy audit, staff are educated and trained. 6. Presentation of the result to management. 7. Action plan for project Implementation. 8. Follow up monitoring to prove result.  Typical annual saving from project with payback period between 0-2 year.  Improved knowledge of process operation leads to reduce energy waste.  Increased awareness of energy cost leads to more management focus on energy use and improved energy conservation.
  20. 20. Conclusion Energy audits, either walk-through or detailed energy audits, are essential for all sectors of the economy (including residential/tertiary sector buildings, School, College, Hotel, Hospital as well as industrial sector and transport companies) to promote a better understanding of the current status of end-use energy efficiency. The audits, which are usually coordinated by engineering or facility departments, will not only create awareness among those who are functionally involved in the management of energy but also justify the necessity for the implementation of energy efficiency activities.
  21. 21. And now last but not the least on behalf of Chamber of Industry, Morang I would like to express my gratitude to FNCCI and GIZ Nepal in supporting and promoting energy efficiency in industries enterprises, with capacity building in Energy Audit as an area of focus.
