Buying energy in bulk is a lot cheaper than what they rip us off for in private households. For our residential/hotel/commercial highrise towers in the Sydney CBD we pay 14c/kWh peak and 10.5c/kWh off-peak on a ~5 GWh annual contract for 2024 (used to be 8c and 6c respectively before the energy market blew up). I don't think 30c/kWh is what an ev charge supplier pays. It's far less than that.

Actually, no. EV charging station operators get gouged mercilessly by the power companies. They're treated as industrial users (think of a small factory). They're charged as if they need huge amounts of power on standby 24x7, on the off chance that the grid might need to supply those huge amounts of power at a second's notice. Which is, umm, true.

The worst offender is Ausgrid (eastern half of Sydney, plus Central Coast, Newcastle & the upper Hunter).

Yep. Until now, there was almost no commercial/industrial electricity user which required a very high peak, but had a low average use. The demand tariffs simply never contemplated there would ever be such a use case, and assumed demand charges based on peak use (required for grid dimensioning) would also be a proxy for average use hence ‘fair’.

But now there is a use case that is nothing like that, but one with a very high peak-to-average ratio (especially in rural/regional areas) and there has been no regulatory response to deal with it.
