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.

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.
