EPRI: DC Superconductors Feasible For Large-Scale Transmission | in News Departments > New & Noteworthy | by Renew Grid on Thursday 04 March 2010   |
A new report from the Electric Power Research Institute (EPRI) says direct current (DC) superconductor cable systems can effectively handle the transmission of thousands of megawatts of electricity between regions. The report further claims that the core technologies behind such systems exist and are ready for commercial development.
The EPRI analysis says superconducting DC transmission lines have the potential to reduce transmission losses at full load by 50 percent or more, compared to alternating current (AC) or high-voltage DC systems. Moreover, if the cost of wire and related technologies continues to decline, installing superconducting DC lines will likely be economically viable within a decade, EPRI says.
The report, which reflects a cable system providing 10 GW of capacity with a nominal current and voltage of 100 kA and 100 kV, also suggests that superconductor systems have the potential to improve the safety, reliability and efficiency of the existing power grid.
