the off-peak rates are about .63 year round with the peak at 6.57 oct-may and 18.26 jun-sep.
the regular rates are about 4.75 oct-may and 5.82 jun-sep.
here is the link to the rates (rate I is regular and rate II is the time-of-use rates)

i just signed up for it myself.
i calculated the cost of running everything evenly all year round (such as a refrigerator for ex) and it would cost a little more in the summer month but less in the winter months. overall, it ends up cheaper on an annual rate. So, if your electic usage were totally even, it would pay to switch (i think, anyone better in math can do a better calculation). If you use more electric during peak than off-peak, it would obviously not pay, and if you can use more off-peak than peak, it would clearly be worth it. The main concern is the 4-summer months in which the peak is really expensive (about 3 times regular rates). Outdoor lights and the like are usually running at night anyway, so those are adding an off-peak bias. If you move the lighting on your tank to the night (like i am) then that too will add an off-peak bias. the biggest issue will be the air conditioner. if you run it all day all week, that may kill it for you. what i will try to do is run my A/C at night and till 10am full blast and then hope the house stays cool for the afternoon. weekends are also non-peak.
in the summer, running 1 hour peak, is costing the same as 3 hours conventional. but running 9 hours off peak, is the cost of 1 hour at conventional rates. or 30hrs of off-peak costs the same as 1 hour peak.
regarding tank lighting, 9 hours of off-peak lighting will cost what we are now paying for just 1 hour.
in the 8 winter months peak rates are not much more than the regular rates (off-peak is still just .63)
