If he has an unregulated rate then the highest I have seen in the past 6 months is $0.12/kWh. However the rates quoted don't include these additional fees on an Enmax bill:
Local Access Fee.
Then another 5% in federal taxes (GST) on top of it all.
A 5 years fixed rate (just on the electricity charge) can be had for about $0.089/kWh (regulated rate). He could be worse off if he foolishly got a regulated rate through a company like Direct Energy.
My Enmax bill is usually 50% higher than the posted pricer per kW/h when all the fees and charges are added.
The only problem with being a man of leisure is that you can never stop and take a rest.
