On 17 June 1972, the Nelson River High Voltage Direct Current (HVDC) transmission system began delivery of electric power.  It used the highest operating voltage to deliver the largest amount of power from a remote site to a city.  The bipolar scheme gave superior line reliability and the innovative use of the controls added significantly to the overall system capabilities.  Finally, the scheme used the largest mercury arc valves ever developed for such an application.</div>
