Projects at our Mt Piper and Wallerawang power stations
Our Mt Piper and Wallerawang projects are aimed towards sustainable development.
About Mt Piper and Wallerawang
EnergyAustralia added two power stations to our portfolio of generation and assets in September 2013 after acquiring them from Delta Electricity: Mt Piper and Wallerawang. These are both located in central New South Wales, less than 200 kilometres from Sydney and within 10 kilometres of one another.
A number of projects are in place to support the management of our Mt Piper and Wallerawang power station assets.
Further details about these projects are provided below,
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 are approved, 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.
Western Rail Coal Unloader
EnergyAustralia developed the idea for the Western Rail Coal Unloader project in order to continue the coal supply needed to operate Mt Piper power station. The Minister for Planning and Infrastructure granted approval in 2009 to construct a rail coal unloader at Pipers Flat. This will ensure ongoing operational needs are met and that Mt Piper will have access to competitively priced coal.
To read more about the Western Rail Coal Unloader, the Environmental Assessment, Submissions Report and Determination can be accessed on the NSW Department of Planning and Infrastructure website.
DDR Project - Wallerawang Power Station
In November 2014, EnergyAustralia announced that it would be closing Wallerawang power station. The Decommissioning, Dismantling and Rehabilitation (DDR) of Wallerawang power station site is a large and complex project that is expected to take at least four years to complete.
To ensure this work is completed in a safe and responsible manner, it will take some time to develop our closure plans in consultation with relevant authorities and the local community.
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. At present, approximately 10.1 million tonnes of ash has been redirected into the currently used ash placement area. Based on the rate in which ash is placed there, this area is expected to reach capacity by 2015.
To combat this, 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, and serves the function of ensuring further ash produced from Mt Piper Power Station is placed in an environmentally sustainable manner.
NSW Department of Planning and Infrastructure provides further information about the Mt Piper Ash Placement Project through their Environmental Assessment, Submissions Report and Determination.
Kerosene Vale Ash Repository
Kerosene Vale was used as an ash dam for Wallerawang Power Station from 1960 to 1990. At this time it had reached capacity and was capped. In 2003 it was then re-opened as dry ash repository to accept dry ash from Wallerawang Power Station. Approvals to expand the dry storage at Kerosene Vale were granted in 2008 (stage 2A) and in 2012 (Stage 2B).

The next step
Following the closure of Wallerawang in 2014 the Kerosene Vale ash repository is now under care and maintenance. In the longer term the Kerosene Vale ash repository will form a part of Wallerawang’s rehabilitation plans.
