How much more will you pay under TOU?

Looking back on my electric meter's historical data downloaded from HydroOne, I have done a quick analysis to see how much more I would have paid under the new structure compared to the old.

Taking data from March 16 to March 29, I used a total of 254 kWh. At a cost of 6.5 cents/kWh under the old pricing scheme, this amounts to $16.51. Under the new TOU structure which came into effect as of May 1 2010, I would have paid $18.64, which is 12% more. This isn't taking into account other additional charges, such as the smart meter charge, delivery, regulatory, and debt retirement charges.

I also did another hypothetical analysis, where I took each hour of extreme high consumption during peak periods and moved it to an off peak time. For example, I ran my dryer, dishwasher, or other major appliance. Hypothetically speaking, if I had run major appliances only during off peak times, then I would only pay 45 cents more under TOU. A more modest increase, but still an increase none the less.
