Abstract

Electric motor systems (EMS) use up to 70% of electricity in Dutch industry. Research and projects show that system optimization and best available drive technology can deliver reductions of 20-30% in pumps, fans and compressors in heating, cooling and ventilation systems, and industrial handling, processing and production systems. Thus lowering the national electricity bill by 5 to 8%. Obstacles in the marketplace and a low awareness of best practice and technology hamper market penetration. Government and the Dutch motor systems industry have started initiatives to accelerate market penetration along 3 lines of activity: LTA-programs, technology network and EMSA.

1000 industrial companies work in LTA’s with the government on increasing their energy efficiency. The LTA´s make the companies accessible and active with thematic workshops, pilot projects, energy audits and technology roadmaps. They operate a required energy management system, based on (elements of) ISO14001. Which is being transformed towards standards as ISO50001 and new methods as the CO2 performance indicator. EMS is addressed and clear links towards organization, procurement and sustainability issues are being developed.

The motor systems industry started in cooperation with NL Agency an ‘knowledge network’ to support the implementation of EMS and raise the awareness of its potential. Representatives of OEM and pump suppliers also participate. Starting by making a short film on EMS, best practice cases, specialized tools, special courses and workshops for industrial companies. The added value of esco’s in this field is explored as well as the points of engagement of the motor systems industry with management standards.

The Netherlands is participating in the Electric Motor Systems Annex (EMSA) – part of the IEA Implementing Agreement 4E. The joint experience of the 6 member countries is applied to provide technical guidance, capacity building and knowledge on performance and IEC/ISO standards.
