  8. Energy Monitoring • 1.Daily Energy report is generated by Central Utility on daily basis and circulated to all concerned. • 2.Monthly Based on daily energy report, monthly energy report is prepared and circulated to all concerned. Comparison & analysis of energy consumption is done with previous months and deviations are studied for reduction in Energy Bills. • 3.Yearly Yearly reports generated from data collected as above. Specific energy consumptions are calculated and targets are set for future. Major ENCON projects are listed in annual report.

  9. ENCON Methodology Identification of high energy consuming equipments/processes through internal & external audits. Elimination of inefficient equipment & substitution with new & efficient technologies. Continuous energy performance monitoring through statistical analysis. Brainstorming in small group activities for innovative ideas. Reduction in Carbon foot print & implementation of green projects. Benchmarking with other competitors. Involvements of employees through suggestion schemes & competitions.

  10. Identification of Major losses 1. Failure losses - Breakdown loss 2. Setup / adjustment losses 3. Cutting blade loss 4. Start up loss 5. Minor stoppage / Idling loss. 6.

  25. ENCON Project : 3 • Title : Commissioning of Biomass Fired Boiler • Loss No- 15 • Background of the project : To reduce Furnace oil consumption for Boilers. • Observation made : • Cost of steam on briquette is almost half that of F.O. • Unused IAEC make F.O. fired boiler of 18 MT/Hr capacity is available. • Can be used by installing external furnace for biomass firing. • Existing underutilized go down can be used for boiler operation and briquette storage. • Technical and Financial Analysis : • Investment : Rs. 332 Lacs • Implemented : Jan. 2010 • Impact of implementation :Reduction in Furnace Oil consumption. • Thereby reduction in SO2 by 108000 Kg/annum and estimated reduction in CER by 11000 per annum.

  26. Savings achieved by converting F.O fired Boiler to Biomass fired Boiler • Avg. Furnace oil Reduction = 200 MT/M • Average Cost of Furnace Oil = 34500 Rs./MT • Yearly Cost savings (Fluctuate as per Price variation in the Fuel) = 183 Lacs/Year

  30. ENCON Project : 4 • Title :Optimization of Cooling water system • Loss no- 15 • Background of the project : • To reduce power consumption for Cooling water pumping. • Observation made : 1. Cooling water high head and low head requirement areas were identified. 2. It was observed that high head heat exchangers were starving due to low pressure although the flow through pumps was satisfactory. 3. The low head areas were provided with positive isolation wherever possible to reduce the unnecessary power consumption and other heat exchangers were tuned for appropriate diff temp for optimum flow. • Technical and Financial Analysis : • Investment : 0.5 Lacs Implemented : Dec. 2012 • 1st year cost Saving : Rs. 44.06 Lacs • Impact of implementation : Reduction in power consumption—5.04 LkWhper annum
