Slide 13: Key Design Features
Key Design Features • 3 x 9E gas turbines (GT) (~120 MW each) + 280 MW steam turbine – Proven, unitised => high reliability – 280 MW steam turbine capacity includes use of duct firing • Duct fired heat recovery steam generators (HRSGs) (~100 MWe) – Effective redundancy for 1 GT/HRSG train – Flexible
Slide 14: Operations and Staffing
Operations and Staffing • Cycling Base Load Operation – Continuous operation – Load to suit gas and electricity market requirements • 35 Staff – 24/7 shift coverage, 4 operators per shift – Small maintenance team on day work – Small engineering team on day work – Management and administration on day
Slide 15: Noise and Emissions Mitigation
Noise and Emissions Mitigation • Extensive noise attenuation – GT generators fully enclosed – GT and ST hall sound insulated – ST bypass valves enclosed – BFW pumps enclosed – Low noise ACC fans • Dry low NOx (DLN) combustors on gas turbines 15 |
Slide 16: Water and Wastewater
Water and Wastewater • Water Supply from onsite bore – Onsite bore from Hutton Aquifer • Air cooled condenser – Water consumption 2% of typical coal fired plant • Water recycling – Boiler blowdown re-treated – Demin plant reject re-treated • Wastewater – Wastewater removed from site by road tanker t
