   Sammanfattning : Due to the ongoing climate crisis there is a need for a transition of energy usage. The transition is dependent on electricity as an energy carrier which puts pressure on the electricity grid to develop at the same rate as the electricity demand increases. However, the process of building new transmission lines is expensive and drawn out. LÄS MER
