At least power prices are only $2000 a year or so, Rental price and interest rate hikes are going to hit a fair bit harder. But yeah, it's still contributing to inflation, because everything is going up, and then corpos will use this as justification to raise their prices even further. Wonder how much of this is because of the fuel price spikes mid last year.
I am on Amber, and yeah we got to directly feel the brunt of it. Other providers absorbed the cost in the short term, to raise their prices in the long term to recoup. The prices on amber are looking a bit more sane these days, but it's still a roller coaster so I wouldn't recommend it unless you want to actually keep an eye on power prices as you're using it. fwiw I'm in SA, which is a little different to the markets in the rest of the NEM. No coal baseload here, coal power is only what comes down the interstate lines.
