Challenge the practice is addressing: In the extractive sector, the use of diesel-powered equipment is common. To reduce carbon emissions and achieve climate neutrality, it is necessary to switch to electric equipment powered by renewable energy.

Concrete practice to achieve the expected goal: For the development of the electric mobile crushing plant, a portable substation that could provide the plant with low voltage electricity was realised in cooperation with ABB. By supplying the quarry with high voltage electricity from the fixed network (locally produced hydro power from the nearby river in Skelleftea), the investment costs are lower. The high voltage electricity has to be converted to low voltage for use in the crushing plant. The next steps will be to connect excavators to the grid, use battery-powered wheel loaders, rock drills and cargo vehicles.

Expected impact/goal of the practice: Reduction of carbon emissions and climate neutrality by 2045. The mobile electric plant will process half a million tonnes of aggregates into fill material. Compared to diesel-powered plants, about 261 tonnes of CO2 will be avoided.

Who is the target user group of the practice/intervention or implementing the practice/intervention? This practice is for companies in the extractive industry.
