Continuous Improvement Leads to Energy Culture


Charter Steel has implemented energy management systems at all their sites with the help of exceptional employees who really helped shift the thought process around energy efficiency in our plants. Jeff Feyen, who is the electrical supervisor for our processing plant, was awarded one of the 2020 individuals taking energy action in Manufacturing awards. Jeff thinks about energy with a continuous improvement mindset. Jeff’s leadership and drive to implement energy projects and get the rest of the plant engaged has really made a complete culture shift towards a more energy aware group of employees. Charter has a long-term energy reduction goal and having Jeff and the processing energy team be so successful from the beginning has given us a great template to roll out energy teams and management systems at our other facilities.
