Delta Electricity

Delta Electricity was formed by the Government of New South Wales in 1996 as part of its reform of the electricity sector in the State, which saw the breakup of the Electricity Commission of New South Wales.

Following a report by the Health Rivers Commission, in 1998 the Minister for Urban Affairs and Planning, Craig Knowles, announced that a small hydro-electric power station would be installed in the Chichester Dam to generate electricity, reduce greenhouse emissions and allow surplus power to be sold back to the State grid. The mini-power station was completed in 2001 and operated by Delta Electricity, and generates up to 110 kW (150 hp) of electricity at times of peak flow; with an average annual generation of 0.4 GWh (1.4 TJ).

As the Keneally Labor government moved to privatise components of the electricity industry in New South Wales including the electricity trading rights of Delta Electricity, on 14 December 2010 four of the five directors of Delta (including the chairman) suddenly stood down in protest over the proposed sale. On 28 February 2011, at the direction of the New South Wales Government, the newly constituted Board of Delta entered into contracts with energy retailer, TRUenergy, for the supply of electricity under Generation Trading Agreements from the Wallerawang and Mount Piper Power Stations. A subsequent NSW Parliamentary Inquiry was held, but the directors of Delta who resigned refused to give evidence before the Inquiry unless guarantees of parliamentary privilege would be given by the Government. Keneally refused to provides guarantees and, according to the Inquiry chairman, the Government stymied the Inquiry's ability to uncover the facts as to the resignation of the directors.

In May 2012, the New South Wales Parliament passed legislation to sell the State-owned generators. In July 2013, EnergyAustralia acquired from Delta Electricity Wallerawang and Mount Piper Power Stations, near Lithgow, New South Wales, for A$160 million. In November 2014, EnergyAustralia announced that it would permanently close Wallerawang due to ongoing reduced energy demand, lack of access to competitively priced coal and the power station's high operating costs. EnergyAustralia began the process of removing useful equipment from the station in 2015 and began demolition of the site when this process has been completed.

In early 2015, the Colongra Power Station at Lake Munmorah was sold to Snowy Hydro. In November 2015, Delta Electricity, which at the time owned only the Vales Point Power Station, was sold to Sunset Power International for $1 million. Delta Electricity was dissolved in October 2016. The NSW Government retained ownership of the decommissioned Munmorah Power Station (Generation Property Management) which is being demolished.

Delta Electricity, as a State-owned corporation has owned and operated the following power stations to generate electricity for sale under contract. Since December 2015, Delta Electricity only operates the Vales Point Power Station.
