Abstract:
Fifty-three percent of all global electricity consumption is used for electric motors which drive for example pumps, and ventilation and compressor systems. In the industrial sector, these electric motor driven systems consume around 70% of total electricity consumption. These motors and their system-components are often outdated and energy-inefficient. By optimising them and increasing their efficiency, a large amount of electricity could be saved.
The International Efficiency (IE) class starts at ‘0’, indicating very old, in-efficient electric motors. IE4 has a ‘super premium efficiency’. When all Dutch IE0+IE1+IE2 electric motors would be replaced by IE3 (which represents the EU regulation, sharpened January 1st, 2017), this would lower the electricity consumption by 3,4% .
Besides replacing the old electric motor for a new one, the driven system could be optimized as well, leading to additional savings. Around 9 TWh (33 PJ) of electricity can be saved if all driven systems within the industrial and commercial sector are optimised. This relates to 11% of total electricity consumption from these sectors and 8% of the total national electricity consumption.
The ‘Green Deal Elektrische Aandrijfsystemen’, a project targeting industrial companies with a so called MJA ‘long term agreements’ on energy efficiency, covers 33% of these savings.
