Major cable project to secure Sydney's electricity supply passes half way mark


Construction is more than 50 per cent complete on the Powering Sydney’s Future project, which will ensure safe, reliable and affordable electricity supply for more than 800,000 people living and working in Sydney’s CBD and surrounding areas.

“We are through about two-thirds of the cable trenching and conduit, with 12.7 kilometres of trenches dug and 19 kilometres of cable laid,” said Project Director Mark McEnearney.

The project will meet the energy needs of the nation’s largest economy, while providing 140 direct and 340 indirect jobs and unlocking $740 million in economic benefits for NSW.

Sydney’s CBD and surrounding areas are currently supplied by electricity cables installed more than 50 years ago, which are now reaching the end of their serviceable life. Crews are currently installing a new 20 kilometre 330kv underground circuit from Potts Hill to Alexandria.

“The 330KV connection will reinforce the supply to the Sydney CBD and surrounding suburbs and allow aged assets in the network to be retired. We currently expect the project to be completed in late 2022.

TransGrid has been working with communities, local councils and other stakeholders since 2017 on the project, which includes upgrades to substations at Potts Hill, Alexandria and Picnic Point. Crews are committed to minimising disruption to local residents and businesses along the route.

“Traffic control teams are working their hardest to minimise any problems or disruption this project may cause. Our teams focus everyday on reducing the impact on communities as we progress construction,” said Mark.

The Powering Sydney’s Future project was approved by the Australian Energy Regulator in May 2018. For more information about the project, visit:
