Dalton Power Project


Proposed Peaking Power Station

In July 2012, the NSW Government approved AGL’s proposal to construct and operate a gas- turbine operated power station of initially 750 megawatts and ultimately up to 1,000 megawatts, four kilometres north of Dalton in the NSW Southern Tablelands. 

Later that year, AGL suspended the proposed power station due to market conditions. 

More recently, the state’s energy requirements have changed and the need to ensure secure, reliable and affordable energy supply in NSW has become increasingly important.

With this in mind, AGL has lodged an application for extension to give time to further consider if the power station is required.

Running on gas, the proposed Dalton Power Station would provide a cleaner source of power that would ultimately assist to reduce reliance on coal-fired power, a long-term aspiration of a cleaner NSW economy.  The power station would form part of the electricity market's response when old high emission coal plants are withdrawn from the market. Gas turbine plants will play an increasingly important role, providing firm capacity to back up intermittent renewable generation.  As 'peakers', gas-fired power stations are important when demand peaks – particularly during summer months when energy use is high.

Development and consultation

The Environment Assessment was completed in August 2011, put on public exhibition (see Downloads page) and submissions were requested. AGL then prepared a Submissions Report addressing the submissions received. This was submitted to the Department of Planning and Infrastructure (DP&I) in October 2011, and was deemed adequate on Friday, 20 April 2012 and loaded onto the DP&I website.

Some of the key facts from the EA and Submissions Report have been summarised on a number of fact sheets. Fact sheets for Noise, Traffic, Air Quality, Flora and Fauna, Visual impact, and Water Supply have been prepared and are available on the Downloads page.

The Director Generals report was uploaded to the DP&I website on 4th June 2012 and sent to the NSW Planning Assessment Commission for Determination. The Dalton Power Project was approved on 19th July 2012 and the determination report and the final conditions of consent are available on the DP&I website.

The government’s approval of the power station is due to expire on 30 June 2017. AGL recently submitted a request to the NSW Department of Planning and Environment to extend the lapse date for two years. If the extension is granted, it will enable us to review the proposed power station in line with the state’s energy needs and current technology. 

The Department will exhibit the extension application from Thursday 16 March 2017 to Friday 31 March 2017. 

During this period, the application can be viewed on the Department’s website and inspected during regular business hours at:

  • Department of Planning & Environment, Information Centre, Level 22, 320 Pitt Street, Sydney 
  • Upper Lachlan Shire Council, 123 Yass Street, Gunning 
  • Upper Lachlan Shire Council, 44 Spring Street, Crookwell 
  • Nature Conservation Council, 14/338 Pitt Street, Sydney.

The extension will also allow AGL to consult with the local community, landholders and other stakeholders on potential modifications to the proposed power station that take into account new technologies and changing energy needs. If required following that review, AGL will lodge a request with government to modify the approved peaking power station.

What we heard and how we have responded

During the environmental assessment of the proposed power station, various stakeholders including community members provided feedback on AGL’s proposed power station.

This feedback included comments on noise, traffic, air quality, flora and fauna, visual impact and water supply. In response to this feedback, and in addition the rigorous regulatory assessments completed for the NSW Government, AGL completed additional studies and assessments, and made modifications to the project, including:

  • The NSW Government assessed the power station on a larger 1,500MW gas-fired plant, and identified that the project would meet all NSW environmental guidelines, including guidelines for air quality even at this larger scale.
  • After additional investigations into groundwater (bore) sources, there was evidence that the bore water will be adequate for the project and won’t affect other bores, meaning trucking in external water supplies will not be required for the power station.
  • AGL will complete ongoing, real-time air quality monitoring during both construction and operation and will make this information publicly available on the project website. 
  • AGL commissioned targeted surveys to assess whether the migratory, threatened Golden Sun Moth (Synemon plana) is present in the project area. The survey confirmed that the Golden Sun Moth does not occur on the site. Additionally, AGL has developed a series of mitigation measures to ensure our activities can co-exist with the moth should it begin to occupy the site.
  • AGL completed a detailed traffic management plan, in order to manage impacts on the community both during construction and operation.  

AGL is committed to leaving a positive legacy in the communities in which we operate. In August 2012, we committed to establish a Community Enhancement Fund for a period of 40 years from the commencement of construction of the power station. The fund will support local community groups and members of the public to enhance the region and will be administered by Upper Lachlan Shire Council.


The proposed Dalton Power Project would be constructed and operated on an area of less than 26 ha within 500ha of land that comprises the site, thereby providing significant capacity for buffer zones. The site continues to be utilised for grazing and it is expected that this would continue if the project proceeds.

During construction, the proposed power station will employ approximately 250 construction workers and, once operational, the facility would require approximately five full time employees. In line with AGL’s commitment to local procurement, we will seek to employ local people for both construction and operations.

How to find out more 

While AGL seeks to extend the lapse date of the project approval, we will be meeting with the Upper Lachlan Shire Council, community members, neighbours and interested stakeholders.
