Construction begins on $49M Bouldercombe Substation rebuild

A contractor has been selected and works are set to begin on a $5.2 million energy depot in Whitsunday, Queensland.

Works have begun to rebuild the Bouldercombe Substation, a critical part of central Queensland’s electricity network that supplies energy to Rockhampton and the wider region.

More than 100 jobs will be supported as part of the $49 million project, which will take around four years. Works will involve the replacement of all primary equipment such as circuit breakers, structure and foundations, as well as the installation of a new transformer.

The substation was first built in the 1970s and has supported industrial and residential growth in the area for more than 40 years.

Rebuilding began in November and will be completed in stages to ensure it can be delivered with minimal customer impact.

The first stage will involve installing the new transformer, which is expected to be completed by late 2021.

Transformers are a significant piece of equipment in a substation that convert high voltage energy from the transmission network down to lower voltage suitable for the distribution network, which then delivers electricity for households and businesses.

Energy Minister Anthony Lynham said the Bouldercombe substation was a critical transmission hub in the region, supplying Rockhampton and surrounding areas.

“The original substation plant is now reaching the end of its service life and requires replacement to ensure a reliable and secure supply of electricity to Central Queensland,” Lynham said.

Powerlink Interim Chief Executive Kevin Kehl said once the transformer installation was complete, the remaining work to replace the primary plant on site would start, followed by decommissioning and removal of the old equipment. This is expected to be completed by mid-2023.

“Our focus is on extending the life of the substation at the lowest long run cost to customers, and with the least disruption to the local community,” Kehl said.
