Energy usage analysis of industries with ETAP case study

There can be huge energy savings if industries are properly monitored and wastages are identified. After identifying the energy loss in Industries, corrective steps can be taken for saving Electrical Energy. To study Electrical Energy losses and to implement energy savings methods, a preliminary energy audit was carried out on a single industrial feeder in an industrial area at Chennai in Tamilnadu, India. The audit team selected 50 industries in that feeder and collected data for estimating electrical Energy losses by designing several questions. The data collection was done by visiting the industries and through telephonic conversation by the Energy Audit team. After analyzing the conditions that were prevailing in the Industries, three vital areas which were contributing Electrical Energy losses,(namely non provision of Capacitors for power factor improvement, non utilization of LED lamps and not using energy efficient ISI mark Star rated motors) were identified and study was conducted. The suggested implementation for the three areas was tested with ETAP simulation and substantial Electrical energy savings was noticed. The total payback period of the proposed recommendation is estimated as 2^½ years.
