The ongoing switch towards more sustainable energy system is one of the most important challenges that society today isfacing. The energy system in Sweden is currently confronted with questions as for example unprecedented electricity prices driven bothby geopolitical constrains and supply constrains in the European energy system. Consumers have also experienced significant differencein price within the country, and existing bottlenecks have resulted in substantial income transfer from the consumers to the transmissionsystem operator. This situation is mainly based on the fact that most of the production of electricity occurs in the north of Sweden, whilstthe demand is relatively higher in the south of the country. Sweden faces a delicate balance between increasing electricity demand andthe need for sustainable, efficient, and resilient energy systems. The energy system in Sweden needs to be resilient and at the same timemeet the upcoming significant increased demand of electricity. It is vital that all available energy sources are included in planning of thefuture energy system. Sweden has a higher use of electricity compared to other European countries, mainly due to historical low electricityprices. This means that there is a potential to reduce the use of electricity in Sweden, which needs to be considered to avoid risk to missthe potential of more efficient use of electricity. There are several studies that are analysing the most optimal mix of electricity production.The aim of this study is to give a review of current research studies dealing with the opportunities and challenges linked to the need fora future resilient Swedish energy system that meets both the today´s and futures need of electricity.
