Moving Toward a Sustainable Energy System: A Case Study of Viken County of Norway

Abstract

Increasing awareness of climate issues and environmental policy has been a key factor behind the continuous transition of energy systems at different levels. This paper aimed to analyse the energy system of Viken county, located in Norway. An energy system model using the energy system analysis tool EnergyPLAN was developed. Based on the reference year 2018, two future scenarios which focus on changes in the transport sector for the year 2030 and 2050 were designed. Besides changes in the transport sector, the integration of renewable energy sources is considered in the future scenarios. The results of the analysis regarding the future scenario shows substantial CO2 reduction as a result of energy-carrier switching within the transport sector. The integration of new energy sources, in this case, solar PV and wind power, helps to offset increased import dependency. The primary energy supply decrease and the share of renewable energy increases significantly.
