With the available transmission technology today, the prospect of importing renewable electricity from remote and thinly settled regions is economically viable and technically feasible. High Voltage Direct Current transmissions have a high availability and reliability rate, as shown by over 50 years of operation. For large electricity transfers, High Voltage Direct Current technology (HVDC) enables very fast control of power flows, which implies stability improvements not only for the HVDC link but also for the entire surrounding AC systems.
