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


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

EnergyAustralia has a permit to build a rail coal unloader at Pipers Flat to supply coal to Mt Piper power station if required. 

We are in the process of arranging long term coal supply for Mt Piper and further information about the Pipers Flat Rail Coal Unloader project will be provided once those arrangements have been finalised.

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.
