Benteler Automotive Raufoss AS saves millions with energy management

Written on .

Health, Safety and Environmental Director at Benteler Automotive Raufoss AS, Arne Håvar K. Grønsund, sees clear advantages to be certified for energy management according to the ISO 50001, as the company has achieved  significant energy savings in recent years. Norsk Energi has assisted this process.

Benteler Automotive Raufoss AS is one of the world's leading manufacturers of lightweight aluminum bumper systems and is one of the largest export companies in the Norway. Benteler delivers its bumper systems to BMW, Volvo, Land Rover and Jaguar and other car manufacturers.

High degree of automation and a strong focus at continuous process improvements are important  to be competitive on an international market. A total energy consumption at the Benteler is approximately 100 GWh distributed between electricity, gas and district heating. Benteler has through several years working system for energy management. In December 2018 received the company a proof that it manages its energy performance well in the form of ISO-5000 certificate from the external auditor DNV-GL.

NORSK ENERGI role in the project: Norsk Energi’s Hans Magnus Myklestad and Oddbjørn Ulland have provided with advice on both energy monitoring and on the development of energy management system, as well as on the identification and implementation of energy efficiency measures. Norsk Energi suggested the energy efficiency measures totaling 6.7 GWh per year. They are related to the improved  automation, new preheating technology,  reduction of energy demand and waste heat recovery from cooling processes at the extruder line.

The foundry represents half of the energy consumption at Benteler at Raufoss. One of the measures at the foundry furnace is a magnet pipe which surges liquid alloy with magnetic pulses instead of manual stirring. This will reduce energy consumption by 2.4 GWh/year.The foundry represents half of the energy consumption at Benteler at Raufoss.
