Horizon Utilities Corporation recognized the efforts of National Steel Car (the only producer of railroad cars in Canada) for saving an estimated 2,192,400 kWh per year through a $247,000 saveONenergyOM Retrofit incentive.
Horizon Utilities’ conservation and demand management teams worked with National Steel Car to assist in finding greater efficiencies. The company uses a compressed air system for pneumatic controls, tools, hoists and painting applications running continuously at full speed 24 hours a day, seven days a week.
The result was the installation of a 350 horsepower trim compressor with variable speed drive and automatic adjustments – dramatically reducing the company’s energy consumption. Compressors are now shut down when air demand is not high, allowing the entire system to operate with greater efficiency and reduce energy demand by approximately 261 kW.
