Toyota

Toyota's engine plant faced excessive compressed air energy costs due to inefficient compressor operation. The legacy air compressor control system lacked optimization capability, resulting in energy waste from uncoordinated compressor staging and excess pressure margins.

Rockwell Automation implemented a new air compressor control system at Toyota's engine plant that optimized compressor staging and demand management. The intelligent controls coordinated multiple compressors to match actual plant air demand while minimizing energy consumption.

Toyota achieved savings of 1 million kWh per year through the optimized air compressor control system. The energy savings translated to significant reductions in utility costs and carbon emissions from the engine plant operation.

Compressed air systems are typically the largest energy consumer in manufacturing plants, and optimization delivers immediate measurable savings. Saving 1 million kWh annually from a single compressor control upgrade demonstrates the scale of waste in unoptimized pneumatic systems. Air compressor optimization ROI in automotive plants is typically achieved within one to two years, making it one of the highest-return energy projects available.
