The Finnish capital of Helsinki, mainly located on a peninsula, suffers a chronic shortage of building space in the city. In a move to redevelop land, the city owned Helsinki Energy has moved its large 500,000 t open-air coal stockpiles to underground storage at the Salmisaari power plant. The open-air storage occupied 100,000 m~2 of land and is to be redeveloped with offices for the high-tech industries; providing an excellent seaside location. The new storage system includes crushing and conveying the coal to large underground silos from where it is fed into consumption storage for daily use. This system of storing coal underground in the bedrock is thought to be the first of its kind in the world. A 98.5 m-high vertical Trellex Pocketlift~R conveyor from Metso Minerals Wear Protection & Conveying (WPC), the same source for the well known Trellex Flexowell~R belts, forms part of the transportation system, taking coal to the surface.
