You can do a bit better than citing a dude with vested interests. You can even find government sources that roughly agree with you: The AEMC report
However the report also notes that:
Delays to new wind and transmission build, and the uncoordinated use of CER are projected to have the biggest impact on electricity costs.
Highlighting that renewables do decrease prices. Of course, reducing gas prices would probably also reduce prices.
Also at least for last quarter the [AEMO] (https://www.aemo.com.au/-/media/files/major-publications/qed/2024/qed-q4-2024.pdf?rev=d75996ee2317495783a18c996d5878ac&sc_lang=en) report that coal and transmission are the driving costs. Negative energy prices were primarily driven by renewables.
Also
Transmission makes up about 50% …
Network costs (the poles and wires) account for about 45 per cent of a power bill and it’s these costs that are on their way up.
I heard it was up to 100% Last time I checked it was 156% Old mate said it was 196%
The actual figure I saw was around 40%, but sure you can inflate things by saying upto.
Renewables do decrease prices though? Maybe l2add?
Because that’s literally what the referenced article states? Maybe l2read?
