Tasmania and QLD are essential to an efficient decarbonised NEM

More solar probably means more firming and more gas

Three portfolios for a renewable NEM

Best wind and solar portfolio.

  • Best = maximise (average output/variability of output)

Lowest cost portfolio

  • Much more solar and gas

ITK’s preferred portfolio,

  • minimises gas (ie carbon),
  • cost is still low, Sharpe ratio high
