Power and Water Corporation used directional boring under road crossings and into properties to install conduits into which the new underground cables will be placed.
Since the project began in 2004, the Darwin suburb of Nightcliff has been fully undergrounded and works in Rapid Creek and Millner are nearing completion.
Undergrounding powerlines lowers the likelihood of power outages in storms, preventing those caused by falling branches and lightning strikes or animals touching the lines and causing the system to short circuit.
Reliability of supply and the life expectancy of the lines are expected to increase dramatically, and removing the powerpoles and overhead powerlines improves the aesthetics of the streetscape.
