Sweden's power system has historically been built around fossil-free, dispatchable generation, with hydropower and nuclear power as stable pillars. This structure has enabled high security of supply and competitive electricity prices. At the same time, Sweden is now facing new challenges, where the electrification of industry and transport and the need to reduce carbon dioxide emissions require extensive expansion of electricity generation. However, the energy policy debate and recurring changes in energy policy are creating uncertainty about long-term investment decisions, which can make a stable energy transition more difficult. Meeting these challenges requires a clear and long-term strategy that creates investment conditions for new fossil-free electricity generation, strengthens security of supply and enables successful implementation of Sweden's climate goals.
