Mt Piper & Wallerawang Power Stations Project

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.

Since acquiring Mt Piper and Wallerawang Power Stations we have created several projects aimed at supporting their ongoing operation and providing a sustainable solution for the Lithgow region. Below you will find an outline of these projects, and an insight into the way we are able to continue providing electricity across New South Wales.

Project updates

Mt Piper Extension

The Mt Piper Extension project first began on 3rd of March 2010, when the Minister for Planning and Infrastructure granted approval for Delta Electricity to install and operate up to 2000MW of additional generating capacity using either coal or gas. This extension continues to add value to the region.

Further information on this can be found on NSW Department of Planning and Infrastructure's website on their Mt Piper Extension Project page.

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.

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 the Mt Piper and Wallerawang Power Stations. The Minister for Planning and Infrastructure granted approval in 2009 for EnergyAustralia to construct a rail coal unloader at Pipers Flat. This will ensure ongoing operational needs are met and both power stations have access to competitively priced coal.

Kerosene Vale Ash Repository - Wallerawang Power Station

Between 1960 and 1990, the Kerosene Vale ash repository was constructed and operational. However, in 1990 it reached capacity and was no longer in use until 2009, when Stage 2A commenced. As Stage 2A was also reaching capacity in December 2011, Delta Electricity was granted approval from the Department of Planning and Infrastructure to complete an expansion. This project (Stage 2B) began in April 2012 and is still underway.

Next step

As of October 2013, ash placement for the Wallerawang Power Station as part of project Stage 2B will commence. This is projected to provide ash storage for between 7 and 10 years.
