Abstract

Small and medium industries (SMEs) savings analysis and meaningful performance indicators can help Enbridge Gas Distribution Inc., and individual SMEs make effective decisions to improve facility performance. For this study, information on 11 SMEs' energy consumption has been provided. This entails: preliminary benchmarking, separation of process and seasonal energy consumption, heating degree days, individual facilities owned reference temperature, normalized annual energy consumption, normalized process and seasonal energy consumption, oven energy consumption, energy balance of oven, energy intensity of oven, and non-productive energy consumption. The most appropriate performance indicator is energy intensity of oven-in bake ovens, cure ovens, and dry-off ovens. The results observed energy intensity in terms of natural gas consumption of bake ovens are from 24m3/ft3 to 30m3/ft3, where the intensity of ovens with finishing process companies are from 8m3/ft3 to 36m3/ft3. Potential natural gas savings from the facilities processing powder coating and baking are 19% to 53% of total oven energy consumption by reducing exhaust energy loss. In the same study observed in analyzing production scheduling, that 8% to 69% of energy consumption can be saved by proper shut-down operation and scheduling.
