New energy recovery plant at Elkem Salten

In April 2018, Elkem initiated a partnership with Kvitebjørn Energi to build an energy recovery plant at Elkem Salten in the northern part of Norway.

The installation is calculated to be able to recover 28% of the electrical energy feed into the plant’s three smelting furnaces. This equals the power consumption of about 15,000 Norwegian households.

At the announcement of the project in April, Elkem’s CEO Helge Aasen said: - This is an attractive and important project for Elkem. Together with our partner, Kvitebjørn Energi, we will continue to develop Elkem’s leading position within energy recovery. The project will increasingly strengthen our competitiveness.

The investment frame of the project is estimated to NOK 1 billion and has been supported by Enova which is the Norwegian government’s funding agency for energy efficiency improvements. It is the second largest investment Enova has ever funded.

The energy recovery plant will position Elkem Salten to become one of the most energy effective silicon plants in the world. Together with other energy recovery installations that have been implemented at Elkem plants over many years this will bring the total energy recovery of the group to approximately 900 GWh per year. The project will therefore strengthen Elkem’s efforts to ensure environmentally friendly silicon and ferrosilicon production with the lowest possible emissions and
lowest possible use of resources.

The project is expected to be finished in 2020.
