Project Facts

  • Supercritical cycle uses less coal and reduces carbon dioxide emissions when compared to a conventional coal-fired power station.
  • Plant uses low sulfur coal mined from the adjacent Commodore coal deposit.
  • Power station uses only 10% of the water typically required by a generating plant of this size.
  • Electricity produced is pooled in Australia’s national grid to meet increased energy demand.
