Flexibility needs in 2035’s Finnish electricity system

This report is an outcome of the teamwork during the Advanced Energy Project L (AAE-E3000) course. The goal for the project was to understand flexibility needs in the low-carbon electricity system in 2035. The report presents various flexibility technologies suited for Finnish system, and through modelling simulates multiple possible outcomes of the mix of technologies in the Finnish energy grid in 2035. In the report suitability of different technologies for mid-term flexibility was examined through total costs and CO2 emissions within 112 different scenarios. From the report it can be concluded that flexibility becomes an increasingly important aspect for the Finnish energy system. The increased penetration of variable renewable sources, which is necessary to achieve ambitious climate goals, requires vast utilization of flexible energy technologies both on the supply as well as demand side.
