The latter are particularly important. While nuclear power has some system costs of its own, it remains the only major dispatchable low-carbon source of electricity other than hydropower which is in limited supply. Carbon prices will thus be an increasingly important tool to differentiate between low-carbon and high-carbon dispatchable technologies. The present study provides a contribution to the debate, which is still ongoing. Further research is necessary and will undoubtedly refine both methodologies and empirical results.
