Optimising energy efficiency is a critical driver for the low carbon future. But while proven technology for energy efficient motors and generators is readily available, customers are not always aware of the possibilities.

That is why ABB has developed the Top Industrial Efficiency( TIE) initiative to ensure that an option with the highest efficiency is always available and visible.

David Bjerhag, Global Business Line Manager, High Speed Synchronous at ABB Large Motors and Generators, outlines below how this higher efficiency option still fulfil all the same requirements as the base offering, but with no compromise on reliability or on using proven technology.

The drive towards sustainability is reshaping industries crucial to our global economy. Energy or manufacturing sectors are facing unique decarbonisation challenges, and the common thread connecting these diverse industries is their reliance on large motors and generators. Since this equipment is indispensable, enhancing energy efficiency is not just nice to have, but essential.

It’ s projected that if all 300 + million industrial electric motors in operation worldwide were replaced with high-efficiency models, global electricity consumption could be reduced by 10 %. Notably, while large motors— those above 375 kW— comprise only a small fraction of this installed base, they account for about a quarter of total energy use.

This highlights the massive potential energy savings achievable by focusing efforts on these heavy-duty components.

Aligning efficiency, cost and sustainability For large motors, generators or motor-driven systems it has been shown difficult to establish minimum efficiency standards given the unique pre-requisites for each installation.

Furthermore, a project typically involves a relatively complex supply chain accustomed to focusing on upfront investment cost instead of the total cost of ownership that the end user bears.

The TIE option is designed to compensate for this by highlighting savings in OPEX as well as CO2 saving over the typical 20-to-25-year service life.
