About the project

The proponent proposes to develop the CopperString Project with an estimated capital expenditure of $1.7 billion. The project consists of an overhead high voltage electricity transmission line, with support towers and associated sub-stations, from a new sub-station at Woodstock, south of Townsville, to the Chumvale sub-station, near Cloncurry.

Subject to demand, the project may extend west to Mount Isa, with spur lines south and north to mines and renewable energy facilities. The project traverses seven local government areas; Burdekin, Charters Towers, Flinders, Richmond, McKinlay, Cloncurry and Mount lsa.

The CopperString project would involve:

  • approximately 740 km overhead high voltage electricity transmission line from Woodstock south of Townsville to Chumvale, near Cloncurry
  • potential for additional network extensions of the electricity transmission line from Chumvale west to Mount Isa and south to Phosphate Hill and Cannington, increasing the length of the transmission line to approximately1,100 km
  • transmission support towers every 400 to 500 metres, depending on topography and height clearance requirements 
  • substations at Woodstock and Chumvale with the potential to include intermediate sub-stations for future connections; plus substations at Mount Isa, Phosphate Hill and Cannington, subject to demand
  • a minimum of four construction camps operating concurrently along the transmission line
  • temporary workshops, site offices, laydown/delivery areas and concrete batching plants for construction activities
  • access tracks used during construction and for ongoing maintenance.

The project is a controlled action and will require approval under the Environment Protection and Biodiversity Conservation Act 1999 (Cwlth) (EPBC Act) before it can proceed (EPBC Act reference: 2019/8416). The relevant protected matter is listed threatened species and communities (sections 18 and 18A) and listed migratory species (sections 20 and 20A).

The EIS will assess potential impacts of the project on the controlling provision consistent with the Bilateral Agreement (section 45 of the EPBC Act) between the Australian and Queensland governments for the purposes of the Australian government’s assessment under Part 8 of the EPBC Act. The Coordinator-General’s EIS evaluation report will be provided to the Commonwealth Minister. The Commonwealth Minister may rely on the outcomes of the Coordinator-General’s assessment process, including any public submissions, in making a decision under the EPBC Act.

Submissions on the draft EIS are invited between 21 December 2020 and 5 pm on Friday 12 February 2021.

The draft EIS is available to view online from Saturday 19 December 2020.
