This paper analyses the transmission efficiency characteristics for two long-distance superconducting transmission designs developed at the IASS and at EPRI as a function of the load factor for capacities up to 10 GW, and in comparison with established transmission technologies. The focus of this study is the planned expansion of the HVDC transmission system in Germany, which is aimed at achieving the current CO2 reduction goals by integrating an increased share of intermittent renewable energy into the grid. The results can be readily extended to other scenarios and can provide complementary information for decision processes directed at planning a sustainable future grid.
