Well I'm completely baffled by the Powerswitch site.

I'm on a standard day/night plan with Contact - they have a huge list of plans. I get "22%" prompt payment / online payment and no paper invoice discount.  Actually to be accurate, it's 20%, then 1% then 1%.

I enter usage data etc either annual or monthly, hit the go button and it comes back telling me that I can save almost $600/year.  Problem is that when I look at details of the plan, the cost per kw/h for both day and night are higher than what I'm actually paying, and at best only offset by a small possible reduction in daily charge.

It makes no sense to me at all, nor does it when everything is averaged into total cost per year saving.

I'm paying net price (incl GST - less discount) per annum:

28.7 per kwh peak x 8000 units = $2296

12.0 per kwh off-peak x 3000 units = $360

Fixed charge + EAL = $310 approx

Total about $2966 PA net.  That seems right.

"Powerswitch" tells me that on "estimated cost" I can save about $560 per year, but when I look at the suggested plan, it's also from Contact, looks exactly the same as the plan I'm on, but the net (including GST, less the same discount I'm already getting) peak and off-peak rates are higher than I'm paying now, fixed fees the same.

Something seems to be very broken with Powerswitch, and I don't know what it is.

I don't think I'm going nuts or have become mentally challenged.  The Powerswitch site appears to be kaput.

... I just got off the phone to Contact.  The plan I'm on is an old one - it's not on the Powerswitch site.  But anyway I entered day and night kwh use on the updated but nearly identical version of the plan I'm on (which actually would save me enough to buy a cup of coffee per year).  My off-peak rate is a little high.  The rates quoted on Powerswitch for the Contact plans are very wrong -it's still telling me I can save $560. The annual total estimated bill and hence savings which could be achieved are completely unreliable.  What a shambles.
