New powerline boosts Bowen Basin electric coal rail network

The electricity supply to the rail network servicing the coal mining industry in the Bowen Basin has been reinforced  with the completion of a new 58km high voltage transmission powerline and substation by Powerlink Queensland as part of QR Network’s Bolingbroke Feeder Station project.

The 132kV line connects the new QR Bolingbroke Feeder Station to Powerlink’s existing substation at Nebo.  The new line enables increased electricity supply to the rail network on the Goonyella System, which transports coal from the Bowen Basin mines to the ports at Hay Point and Dalrymple Bay.

The powerline forms part of QR Network’s Bolingbroke power strengthening project which will increase the overall operational efficiency of the Goonyella System in Central Queensland.

By boosting the electrical capacity of the rail network servicing coal mines in the region, the new line also supports expansion of the coal export industry that underpins the region’s economic growth.

Powerlink constructed the transmission line and a portion of the substation works in conjunction with QR Network after undertaking a comprehensive Environmental Impact Assessment for the project, in consultation with landowners and other stakeholders to ensure that any potential environmental and social impacts were minimised.

Helicopters were used during construction to string conductor wires onto transmission poles, which minimised the need for heavy machinery on the ground and reduced the time taken for stringing activities.

Rocla supplied approximately 140 spun concrete poles for the project, in heights of 30 and 36 metres and 80kN strength, in two and three sections for assembly on site.
