❓ Dr. Pettitt questions the Minister for Energy regarding SWIS demand in 2030, gas generation requirements, and requests modelling data. The Minister provides demand figures, gas generation capacity projections, tables SWIS modelling, but cites cabinet-in-confidence for coal plant retirement modelling.

RENEWABLE ENERGY
1534. Hon Dr BRAD PETTITT to the parliamentary secretary
representing the Minister for Energy:
I refer to the answer to question
without notice 1381 answered on 8 November 2023.
(1) According to the modelling, what is the expected
demand on the south west interconnected system in 2030?
(2) How many
megawatts of gas generation will be required to meet the remaining demand,
after existing coal units are closed and the projected 810 megawatts of wind
and 1 100 megawatts or 4 400 megawatt hours of storage is installed?
(3) Will the minister please table —
(a) the Energy Policy WA modelling
for the SWIS; and
(b) the state-owned coal plant
retirement modelling referred to in part (1) of the answer?

AnswerView source ↗
I thank the honourable member for
some notice of the question. The following answer has been provided to me by
the Minister for Energy.
(1) The south
west interconnected system demand assessment modelling shows an annual
electricity demand on the SWIS of 32 600 gigawatt hours in 2030, with a peak
demand of around 5.9 gigawatts.
(2) Modelled outcomes from the SWIS demand assessment
for required gas generation capacity are as follows . In 2030, gas
generation capacity is 3.34 gigawatts, of a total 13.4 gigawatts of generation
capacity, and contributes eight per cent of
energy consumed in the SWIS. In 2042, the end of the study period, gas
generation capacity is 6.18
gigawatts, of a total 56.2 gigawatts of generation capacity, and contributes
three per cent of energy consumed in the SWIS. Actual gas generation capacity
required will be subject to a range of factors.
(3) (a) The
answer says ''see tabled document'' titled, ''South west
interconnected system (SWIS) demand assessment modelling outcomes''. I believe
that is attached to the answer, so I seek to table that document.
[See paper 2868 .]
(b) The Synergy modelling is
cabinet-in-confidence.
