  • NRG Energy Successful in Bid for Flinders Power in South Australia
    NRG Energy Successful in Bid for Flinders Power in South Australia August 2, 2000 MINNEAPOLIS, Aug 02, 2000 (BUSINESS WIRE)---NRG Energy, Inc. (NYSE:NRG) announced today it has been named the successful bidder in the South Australian Government's electricity privatization auction for Flinders Power, South Australia's final generation company to be privatized. NRG agreed to pay (Aus.) $313 million ($180 million U.S.) cash for a 100-year lease of the Flinders Power assets. Flinders Power includes two power stations totaling 760 megawatts (MW), the Leigh Creek coal mine 175 miles north of the power stations, a dedicated rail line between the two, and Leigh Creek township. The lease agreement also includes managing the long-term fuel supply and power purchase agreement for the 180-MW Osborne Cogeneration Station. NRG expects to close the transaction in early September. "Flinders gives NRG a strong position in the vibrant South Australian power market," said Keith G. Hilless, NRG Asia-Pacific managing director and CEO. The power stations are the 240-MW Playford Power Station and the 520-MW Northern Power Station, both located in Port Augusta on the Spencer Gulf--approximately 190 miles north of South Australia's capital city, Adelaide. The Playford and Northern power stations use pulverized coal-fired steam turbine generation technology. Northern is a baseload facility and is the lowest-cost generator in South Australia, while Playford is a peaking facility. "Flinders Power confirms our long-term commitment to the Australian power generation market," commented David H. Peterson, chairman, president and CEO of NRG. "This project is right in line with NRG's strategy of acquiring assets that complement our core portfolio and represent a variety of dispatch levels." Flinders Power, which NRG will operate, is the only generator in South Australia to own its own fuel source.

  • Business As Usual at CS Energy's Callide C Power Station
    Friday, 8 July Business as usual at CS Energy’s Callide C Power Station Callide C Power Station in Central Queensland will continue to operate as normal despite IG Power (Callide) Limited being placed into receivership on 14 June 2016. IG Power (Callide) Limited owns a 50 per cent share of the 810 megawatt, coal-fired Callide C Power Station in a joint venture with CS Energy. In addition to being a 50 per cent owner of the Callide C Power Station, CS Energy is the operator and the supplier of services to Callide C under an Operation and Maintenance Agreement (OMA) and Station Services Agreement (SSA). Acting CS Energy Chief Executive Officer, Andrew Varvari said this development had no impact, and was not expected to impact, the operations or the workforce at Callide Power Station. “For CS Energy, it has been, and continues to be, business as usual at Callide C Power Station,” Mr Varvari said. “We are continuing to generate electricity and supply the National Electricity Market with power, and there has not been, and we expect going forward there will not be, any impact for our workers at the power station. “As is normal in these types of situations, CS Energy continues to meet with the receivers to discuss relevant business requirements. “We will continue to work with them to ensure that we achieve the best possible outcome for the ongoing operation of the Callide C Power Station,” he said.

  • Implications of a 50% Renewable Energy Policy on Queensland's
    Implications of a 50% renewable energy policy on Queensland’s energy sector Prepared for: The Australian Institute for Progress By: Jonathan Pavetto Date: 20 November 2017 Summary A 50% by 2030 renewable energy target has been extensively modelled by the Australian Energy Market Operator in their 2016 annual National Transmission Network Development Plan (NTNDP) update. The AEMO modelling shows that to achieve a 50% generation mix by 2030: a combination of closing existing coal generation and increasing renewable generation is required. 1400MW (Stanwell Corporation’s Tarong plant near Kingaroy) will need to close by 2018/19, 1460MW (the Stanwell plant near Rockhampton) also will need to close by 2026/27. 560MW (two of Gladstone Power Station’s 280MW units) is expected to be withdrawn in 2020-21 and another 280MW unit (a third unit in the same power station) in 2028-29. Most of the shortfall in generation is expected to be made up by rooftop solar PV, with only small gains in gas, large-scale solar and hydro. A 50% by 2030 renewable energy policy has a number of implications: Closing down the Tarong and Stanwell power stations, as well as three of Gladstone’s six generation units will cause job losses in Kingaroy, Rockhampton and Gladstone – all areas with unemployment rates already above the state average. Coal-fired electricity generation has a higher capacity factor to renewable generation. Transitioning from coal to renewables can cause localised system weakness because of the lower power factor in areas with high penetration
