Energilager i Luleå Energis elnät
This thesis will investigate possible energy storages in Luleå Energi’s power grid within a five-year period. The transition to a more sustainable and efficient energy system, in response to climate change, creates new challenges for the power grid. Energy storage has, according to many sources, the...

This thesis will investigate possible energy storages in Luleå Energi’s power grid within a five-year period. The transition to a more sustainable and efficient energy system, in response to climate change, creates new challenges for the power grid.
