Sorry Dave ... 8pm - 10pm weekdays is Shoulder Rate.
I think last time I worked out the equivalent flat rate it was around $0.18c/kWHr ... maybe 18 months ago ... whereas Mum & Dad who are on a Flat Rate metering system (old fashioned spinning wheel meters) were around $0.25c/kWHr.
Alot of people get confused with the time of use metering system (understandably) ... but it's simple if you work on the premise that you AVOID 2-8pm weekdays ... any other time, it's cheap!
If I get a chance I'll see what my last bill works out at ...
