Knowing how process energy (i.e., the power needed to manufacture finished products) affects manufacturing and then increasing the intelligence behind it are keys to improving overall energy use and operational efficiency.

Schneider Electric implemented a process-energy monitoring and control system for its electrical enclosure paint process. The monitoring system uses energy data along with power quality information to communicate with the paint process’s programmable logic control systems to

  • identify and optimize energy usage by process;
  • identify operational anomalies;
  • determine energy consumption by product; and
  • identify energy anomalies.

Results include increased production, increased equipment life, improved maintainability, and reduction of overtime costs. Two additional key lessons learned: there is significant return on investment when energy costs are optimized, and the system provides a solid framework for compliance with ISO 50001 Energy Management Standard.
