SOUTH WEST
INTERCONNECTED SYSTEM
380. Hon Dr BRAD PETTITT to the parliamentary secretary
representing the Minister for Energy:
(1) Is the minister aware of modelling recently
published in Renew Economy that shows that 85 to 90 per cent of
renewables on the south west interconnected system electricity grid would
deliver cheaper electricity than currently provided
on the SWIS, which has only around 30 per cent renewable energy, and would also
emit around nine million fewer tonnes of CO2 per year?
(2) Is it correct
that the Western Australia government's current Whole of system plan,
the most plausible generation plan for 2040, will emit six million tonnes more
CO2 than 90 per cent renewable energy?
(3) Has the
government modelled and costed 85 to 100 per cent renewable energy electricity
on the SWIS and the emissions reductions achievable by doing this?
Hon MATTHEW
SWINBOURN replied:
I thank the member for some notice
of the question. The following information has been provided to me by the
Minister for Energy.
(1) Yes.
(2) The Whole
of system plan modelled four different scenarios for how the demand for electricity
on the SWIS might change over 20 years. It was not a plan for implementation by
government.
(3) The next WOSP
process is to commence shortly with stakeholder consultation on the different
electricity scenarios to be modelled. This
will include a consideration of how to meet the net zero emissions by 2050 commitment
in the Western Australian climate policy. The final WOSP report is due to be
delivered in 2023.
