Interesting! I enjoy that 9-10pm is also a magical $0 FiT time in the ToU minimums too. Like hey the market at 3:15pm is going gang busters for your solar but at 9:20pm they want none of it. And then 10:05pm back to valuable.

Meter readers is a good idea. Whenever I hear SAPN and controlled load it takes me back to 2014 where electronic timers were way to accurate and caused high ramp rates from all the circuits switching at the same time.

Even in 2014 they mention daytime HW heating! www.aer.gov.au/system/files...
