It will depend in a lot of factors, including the age of the home (how energy efficient it is) and your personal settings for A/C, electroincs usage etc.
In May '08 SRP will raise the price of electricity to $9.60/Kwh, still relatively low to S. California which is in average $14.74/Kwh.
For SRP clients living in a 1,000/SF to 1,500/SF home the average energy use (with the new pricing) is $164/Month if you own a pool and $132/Month if you do not own a pool. Again this are just averages and will vary greatly depending on your personal usage.
On my website I have a list of average annual cost of services per city, this includes city property tax, sales tax, sanitation water and sewer. For Tempe it is $1,477.
Hope this helps...
