5 and new sensors placed at key locations within manufactur- ing processes or by using data from existing sensors and manufacturing systems. For compressed air systems, these sensors collect data on electricity usage, air flow and system pressure. Combined with external data, such as weather information and production information, a picture of system performance is created and made available to the user, such as plant managers and operations teams. Another useful feature of Lightapp’s online platform is that it allows plants to compare their performance to other monitored facilities, although the identities of the facilities are kept private. This feature, called the Arena, provides an external perspective on plant performance, serving as a benchmark for efficien- cy and allowing plant managers to identify if their facility or facilities are functioning in line with other manufacturers, including competitors. Data collection and analysis is still ongoing and will continue into late 2019, but individual plants have already generated several success stories. A packaging company used the data and analysis from Lightapp to identify key issues with the compressed air system and find a low-cost solution rather than investing in more expensive repairs and equip- ment. By repairing leaks and replacing a dryer, the plant avoided spending more than $100,000 on new compres- sors and piping while still increasing efficiency and saving energy. A soft drink manufacturer also utilized the data and reports from the Lightapp EMS to reduce the electric- ity used by the two compressors running the low-pressure compressed air system. The monitoring showed that the system was not performing efficiently, and identified that the compressor running the majority of the time did not have a variable speed drive (VSD), while the compressor Project Engage is Increasing Efficiency through Optimized Energy Management Figure 1. The top image shows the baseline performance for the soft drink manufacturer, with the VSD compressor (blue line) used as backup. The bottom image shows the performance after input from Lightapp, with compressor use balanced across both pieces of equipment and lowering total electricity usage.
