The Chinese Motor System Optimization Experience: Developing a Template for a National Program

Industrial electric motor systems account for more than 50% of China’s electricity use. If optimized, their efficiency could be improved by 20%. In response to this opportunity, China established a Motor Systems Energy Conservation Program in cooperation with the UN Industrial Development Organization, the US Department of Energy, and the Energy Foundation. A previous paper described progress at the mid-point of this pilot program. This paper presents the final results documented in case studies, and training activities and through a final independent program evaluation. The focus is on the efficacy of transferring complex system optimization techniques across languages and cultures using classroom instruction and hands-on measurement and assessment training in factories. Details are provided on lessons learned, including the strengths and weaknesses of the training model in preparing Chinese engineers to conduct plant assessments, develop projects, and train factory personnel.
