EnergyAustralia has begun work on a $6 million project to make the electricity network in Sydney’s inner west safer and more reliable.

About 1.5 kilometers of cable will be pulled off shop-fronts in King Street, Newtown, and placed underground as part of the multi-million dollar project.

EnergyAustralia’s General Manager Reliability John Eisenhuth said the 18-month project would improve the power supply for local homes and businesses and make the streetscape look neater.

"The existing cables served the community well over the last 20 years, but these types of cables are now installed underground to make them more reliable and safer for power crews to access when needed," Eisenhuth said.

Specialist crews have been carrying out preliminary work installing new connection points for the new cables, called turrets or pillars, which is the first stage of the project. Pillars were installed first to reduce disruption to the community over the busy Christmas and New Year periods.

The new cables will be buried in trenches under the footpath along King Street, from Missenden Road to Enmore Road. These underground cables will be connected to the new pillars being installed on footpaths, and each pillar will supply four buildings.

"We have begun excavating some trenches along part of the footpaths to house the cables," he said. "Temporary reinstatement of the footpath will be completed each day and a permanent reinstatement of the footpaths will be undertaken once all works in the area are completed."

When all cabling work has been finished, existing cables from building facades will be removed.
