❓ Dr. Pettitt asks about the modelling behind WA's renewable energy targets, specifically regarding replacing state-owned coal generators. The response details the required renewable energy capacity (810 MW wind) and storage (1100 MW/4400 MWh) by 2030.

RENEWABLE ENERGY
1381. Hon Dr BRAD PETTITT to the parliamentary secretary
representing the Minister for Energy:
I refer to the modelling done by
Energy Policy WA for the south west interconnected system and to the answer to
question without notice 1180 asked on 10 October 2023 that the WA government
has an ambition of 82 per cent renewable energy by 2030, with an expectation of
84 per cent renewable energy on the SWIS.
(1) From the
modelling, how many megawatts of renewable energy will be required to replace
state–owned coal generators by 2030?
(2) If available,
how much of this renewable energy in 2030 is expected be from —
(a) wind;
(b) large-scale
solar;
(c) rooftop
solar; or
(d) other?
(3) From the
modelling, how many megawatt hours of storage, and what duration, will be
required to support the above renewable energy to replace state–owned
coal generators in 2030?

I thank the honourable member for
some notice of the question. The following response has been provided by the
Minister for Energy, which I provide on behalf of the parliamentary secretary.
(1) State-owned coal plant retirements was the subject
of a separate modelling exercise. This modelling showed a combination of
810 megawatts of renewable energy would be needed, as well as storage. See the
answer to question (3).
(2) (a) Wind is
expected to provide 810 megawatts.
(b)–(d) Not
applicable.
(3) The modelling showed that 1 100
MW/4 400 MWh of storage would be required.
