South West Interconnected System—Whole-of-system
plan
1015. Hon Dr Steve Thomas to the Leader of the House
representing the Minister for Energy and Decarbonisation:
I refer to the state
government's utter inability to deliver the updated South West Interconnected
System whole-of-system plan by the end of September 2025. It might be a
Thursday!
(1) Did the government commit to delivering an
update to the plan in 2023 following its announcement in 2022 of the closure of
coal-fired power stations under its energy transition?
(2) Did the government utterly fail to deliver
that proposed update?
(3) Did the government then publicly advise that
it would deliver the update by the legislated time of 30 September 2025?
(4) Has the government now utterly failed again to
deliver in this second timeframe and set a new proposed delivery timeframe of
30 September 2027?
(5) Why did the government try to hide this latest
failure instead of being honest with the WA community?

AnswerView source ↗

That was a very long
question. I thank the honourable member for some notice of the question. The
following answer has been provided to me by the Minister for Energy and
Decarbonisation.
(1)–(5) In response to feedback from
industry requesting a tangible plan on the timeframes and locations of new
transmission infrastructure, the government released the South West Interconnected System Transmission Plan:
Powering our state's future in September 2025. The next whole-of-system
plan (WOSP) will be delivered by 30 September 2027, consistent with the recent
update to the Electricity System and Market Rules .
