Kidston power proposal gets a boost

Kidston power proposal gets a boost

Genex Power’s $580 million energy project near Kidston, 280 kilometres north-west of Townsville, has been granted special status as a prescribed project said Minister for State Development and Minister for Natural Resources and Mines, Dr Anthony Lynham.

‘Prescribed project’ status would enable the Coordinator-General to assist Genex Power to progress the project, including ensuring timely approvals across governments said Dr Lynham.

The project on the site of the former gold mine will create more than 500 local jobs. Genex proposes:

  • a 150 megawatt solar power generation farm
  • a 330 megawatt pumped storage hydroelectric scheme, using the former mine pits and their stored water
  • 185km transmission line to carry power to the coast and the main Powerlink line between Townsville and Cairns.

“The Kidston project will support our policy to generate 50 per cent of Queensland’s electricity needs from renewable energy by 2030,” Dr Lytham said.

Dr Lynham said the project was a first in terms of co-locating large scale solar with large scale energy storage.

“And it’s re-cycling the infrastructure of the former Kidston gold mine which closed in 2001, a world first by using a disused mine site for hydro-electric power generation,” he said.

The $300 million solar farm involves installing solar PV on the former mine’s 300 hectares of rehabilitated tailings storage area.

It is one of 10 Queensland solar projects shortlisted earlier this year by the Australian Renewable Energy Agency.

The pumped storage hydroelectric project, which is being developed in parallel, is proposed to be Australia’s third largest hydro power generator, at 330 MW.

Construction starts on the solar farm in the final quarter of 2016 and on the hydroelectric project and transmission line in 2017.

“The project has the potential to meet all the peak power generation demands of North Queensland and some of Central Queensland,” Dr Lynham said.

The design of the hydro project proposes for water to be released from one of the former mine pits into the other through reversible turbines. This is similar to Wivenhoe Power Station at Lake Wivenhoe, 90km north-west of Brisbane, and the Snowy Mountains Hydro-electric Scheme in New South Wales.

During off-peak power consumption periods, the turbines will function as pumps and pump the water back into the upper reservoir to repeat the cycle.
