Abstract

In 2030 the electricity sector in the Faroe Islands should be 100% renewable, according to the local electrical power company SEV. It is therefore necessary to study, how this goal can be reached with the minimum costs. This can be determined through optimisation of the future electricity sector. This paper presents such an optimisation. The optimisation is conducted using the computer simulation tool Balmorel, which has been developed for the purpose. Two of the seven power grids in the Faroe Islands are modelled, and input data such as weather and projected demand are defined. The model is allowed to invest in wind, solar and tidal power, in addition to pumped storage systems. The results show that if the least-cost path to a 100% renewable electricity is followed, SEV should invest in 98 MW of wind power, 125 MW solar power, a battery system of 1.6 MW/6.7 MWh and a pumped storage system with a storage of 7.3 GWh. Additionally a cable between the two investigated grids should be installed, to allow for transmission between the grids. In order to get better and site specific results, the model should be expanded with extra demand profiles and input weather data.
