The state government says a lack of renewable could delay the start of the proposed CopperString project.
The Queensland government declared CopperString a coordinated project in May to fast-track approvals however Minister for Natural Resources, Mines and Energy Anthony Lynham said for CopperString 2.0 to operate it would rely on a lot of renewables hooking into the transmission network.
"Renewable energy is the cheapest form of energy available but the trouble is the LNP state (opposition) does not support renewable energy," Dr Lynham said.
"If they ever got into power we would be competing against coal fired power."
LNP Shadow Energy Minister Michael Hart said the LNP supported the CopperString project and have committed to fast-tracking approvals for the project.
'It's time Labor stopped playing politics and stopped talking down private sector investment in Queensland," Mr Hart said.
'The LNP supports renewable energy and is proud the large-scale renewable energy investments in Queensland have only been made possible by the Federal Government's renewable energy target and industry support programs.
Dr Lynham said the state government had put in $1.8 million to support the project.
"We are hoping we get some NAIF funding from the federal government which would really kick start things," he said.
"If all the ducks lined up we could be starting construction of CopperString 2.0 in 2022."
However the CopperString project believes it can achieve the approvals to begin construction in late 2020 to early 2021.
