Decommissioning

Maria Hassel, project manager of the dismantling operation for Vattenfall, commented:

The turbines that were installed at Yttre Stengrund were an early model and only about 50 of them in total were actually produced. The difficulty of getting hold of spare parts and the huge cost involved in upgrading the turbines and gearboxes meant that it wasn’t financially viable to replace the turbines.^[2]
