Delta Electricity was formed on 1 March 1996 as part of the New South Wales Government's restructure of the State's electricity industry. The State owned corporation operates under the Energy Services Corporations Act (1995) and the State Owned Corporations Act (1989).
Delta operates four coal fired power stations, two of which are located in the Coxs River catchment at Mt Piper and Wallerawang, about 160 km west of Sydney near the township of Lithgow.
The water management licence issued to Delta authorises the taking and use of water from the Coxs River for power generation purposes and includes Lilyvale Dam (Lake Lyell), Wallerawang Dam and Thompsons Creek Reservoir. The licence contains clauses relating to:
- water releases from all storages, including a comprehensive environmental flow regime downstream of Lake Lyell
- management of the water management works
- the inter-dam transfer of water
- water use efficiency
- river health monitoring and reporting requirements.
Water management licence review
The Office of Water is undertaking a review of the Delta Electricity Water Management Licence (PDF 574 KB) as required under section 193 of the Water Act 1912 (NSW). As part of the review submissions were invited from the public to comment on the licence and the activities of the licence holder during the second five-year term of the licence from July 2005 to June 2010. The consultation period ended on 9 July 2010.
The Office of Water will consider the issues raised with regard to the scope of the review and amend Delta's licence if required. The licence will be available here soon after it is re-issued.
