7 China motor system energy saving policies Energy Efficiency Front Runner Seven government ministries (NDRC, MOF, MIIT, NEA. AQSIQ ) jointly published the energy efficiency front-runner system implementation plan in Scope of implementation: endusing energy products, energy intensive industries and public institutions. 7

8 China motor system energy saving policies The tier 1 electric motor is nominated as the front-runner motor In public financed projects, front-runner motors will be used with higher priority. 8

9 China motor system energy saving policies Supervision on elimination of inefficient electromechanical equipment On-site spot check at the factories using motors If the inefficient motors listed in phase-out category are still in use by the deadline, the electricity tariff will be increased dramatically 9
