A number of sustainable development projects are currently underway at Mt Piper power station.

Nu-Rock

EnergyAustralia entered into an agreement with Nu-Rock in 2014 to build a pilot plant that uses fly-ash from Mt Piper power station to manufacture building materials such as bricks, pavers and concrete blocks.

Should the test plant prove successful, Nu-Rock will look to build a larger facility capable of manufacturing these products in a commercial quantity. If these plans proceed, the facility would look to employ up to twenty people and be set to use 250,000 tonnes of Mt Piper’s fly-ash each year.

Pipers Flat Rail Coal Unloader

To make sure we can continue to source the coal needed to operate Mt Piper power station, EnergyAustralia is exploring the option of building a rail coal unloader facility at Pipers Flat. 

Today, all of the coal for Mt Piper comes from the nearby Springvale mine. This project would enable EnergyAustralia to source coal from other mines and transport it via rail to the power station. The ability to supplement and diversify its fuel supply will help make sure Mt Piper can continue to operate in future, even if there is an interruption to local coal supply.

The project, which received approval from the NSW Department of Planning and Environment in 2009, involves the construction and operation of: 

  • a rail loop which connects to the main line   
  • a coal unloader building located on the loop
  • a conveyor system which carries coal from the unloader building to the power station

EnergyAustralia submitted a modification application to the Department of Planning and Environment in August 2018. The modification was approved in January 2019. The application included a revised design to improve efficiency and reduce the environmental impacts of the development, as well as a request to extend to the required start date of the approval permit.

Our aim is to get an outcome that’s good for the environment and the community, and to ensure no interruption to Mt Piper power station that supplies up to 15 per cent of New South Wales’ electricity demand, the equivalent of 1.2 million homes.

Mt Piper Ash Placement Project

With a generating capacity of around 1400MW, there is a need to provide advanced ash placement to better serve the environment of the Mt Piper region. In 2012 a proposal was put forth to the NSW Minister for Planning and Infrastructure to create a new ash placement area in Lamberts North. This was approved and construction was completed in May 2013. This will ensure further ash produced from Mt Piper is placed in an environmentally sustainable manner.

Energy Recovery Project

After careful consideration of the project’s technical and economic merits, EnergyAustralia has decided to withdraw from the Joint Venture with Re.Group in pursuing the Energy Recovery project at Mt Piper.

In light of this, Re.Group is now exploring options to enable a modified version of the project to proceed.

Both EnergyAustralia and Re.Group would like to thank the many people in Lithgow, Wallerawang and Portland who were willing to listen to our proposal and engage with an open mind. The feedback from the community was genuinely appreciated.
