Mihai Priboianu, ABB: New technologies drastically reduce power consumption


Efficient motors and converters have a vital role to play in reducing power consumption, said Mihai Priboianu – product Manager, ABB Romania, during the conference “Digitalization and Energy Efficiency – Brasov”, organized by Energynomics.

“It is currently estimated that for commercial buildings, more than a third, almost 40% of electricity consumption is generated by electric motors. If we speak of an industrial level, more than 70% of the consumption is generated by electric motors. The new engines ABB makes available to the market have an efficiency class of at least IE3,” said Mihai Priboianu.

New engines with at least IE3 efficiency class and frequency converters can help reduce the carbon footprint; the involvement of key policymakers such as public authorities with measures to regulate the large-scale adoption of new technologies will make the difference. Also, companies and cities need to be aware of the savings that can be made by adopting these technologies. At the same time, producers such as ABB must continue to improve the technologies leading to increasingly better energy efficiency and the bodies involved in education to explain and promote the benefits of using new technologies.

”I welcome awareness campaigns, as we saw it happen in Brasov. It is important not only to raise public awareness but also in the industry, residential etc. Awareness is very important for the adoption of these technologies,” he said.


In a building, multiple systems are powered by various medium and large motors, which generate about 67% of consumption for medium and 23% for large ones. ABB engines are energy efficient, with standard efficiency of at least Premium IE3, while now there is already talk of the IE4 and 5 standard, which enjoys increasing market opening.

”An efficient system that uses an efficient engine and a converter achieve more than 82% efficiency. Consumption shall be reduced by up to 25%. New technologies are here and we at ABB are part of this trend to adopt new technologies and ready to adopt these solutions,” he said.

At the same time, the impact of digitalization and connectivity is crucial in making electric drive systems more efficient, with real-time adjustments.

It is estimated that more than 300 million systems are powered today by electric engines. If all were replaced by new technologies, global energy consumption would fall by 10%. However, adoption involves regulatory policies that may require the adoption of technologies with a major impact in achieving energy efficiency and optimizing electricity costs for a rapid return on investment in new technologies.

“The major benefit of new technologies is the real possibility of reducing greenhouse gas emissions by 40% by 2040, in line with the Paris Treaty.”

The conference “Digitalization and Energy Efficiency – the 5th year – Brașov” was organized by Energynomics, with the support of our partners ABB, Eaton România, EnelX România, Kawasaki Gas Turbines Europe, Wiren Energy.

More than 200 people registered on the MyConnector platform to participate in the dialogue.
