For transmission (at least in NSW) there’s a fair bit of bad blood because transgrid has a history of building unnecessary powerlines. They get paid on their asset base and were building a lot of powerlines that had no use in any reasonable projections, only in bullshit projections from transgrid.
That’s now made it very hard for these projects to be done as there’s a history of the bad projects that’s pretty recent.
I’m not saying that these aren’t necessary now, but it’s no surprise people are opposing them with the history transgrid has.
For example they dumped a proposed Stroud to landsdowne powerline around 2012 after it was shown to be just the trying to increase their regulated asset base
