The Chinese Motor System Optimization Experience: Developing a Template for a National Program
Industrial electric motor systems consume more than 600 billion kWh annually, accounting for more than 50% of China’s electricity use. If optimized, the efficiency of most industrial motors systems in China could be improved by 20% or more. In response to this opportunity, China established the China Motor Systems Energy Conservation Program in late 2001 in cooperation with the United Nations Industrial Development Organization, the US Department of Energy, and the Energy Foundation.
A previous paper described progress at the mid-point of this 3-year pilot program in Jiangsu and Shanghai provinces. This paper presents the final results of the pilot program, as documented in case studies, completed projects, plant assessments, and training activities and through a final independent program evaluation. The focus is on the overall efficacy of transferring complex system optimization techniques across languages and cultures using the pilot program model of classroom instruction and hands-on measurement and assessment training in factories. Details are provided on lessons learned both during and after the pilot program, including the strengths and weaknesses of the training model in preparing Chinese engineers for conducting plant assessments, developing projects, and training factory personnel. The role of regional, cultural, and organizational differences in program implementation are addressed. Also included is a description of follow-along system optimization activities and organizational impacts among the trained experts in Jiangsu and Shanghai. A national program is described that includes working with this core of experts to introduce systems optimization training in additional Chinese provinces. Finally, practical implications for refining and applying the program model to other countries in Asia, Eastern Europe, and elsewhere are discussed.
