With a 60-40 summertime split, my bill in Hidden Valley on APS TOU usually looked like this. Also, I was on Demand Billing which means you run one or two appliances during peak at a time only in order to cut your demand KWH per hour down. 1200 KWH used 40%peak=480kwh @11.5 cents a KWH=55.20 60% off peak 720 @.04 cents a KWH=28.80 On demand factor of 5=60.00 (this dropped way down w/o the A/C fall, winter and spring to 1 or 2 Total cost was 144.00; central air, 14000gal pool and two casement A/C Plus tax, fees and misc. This was between 1998 and 2004. Since have moved off grid. Total elect use for year was around 1300 dollars. Winter time rates were even cheaper, although the service charge minimum did increase somewhat. We were on level billing which gave us a constant 105.00 per month payment. Domicile was single wide mobile home and had two window units in an expansion area that ran constantly all summer as build out was on south side. Also used a 6500CFM whoe house evap cooler before and after monsoons. Heating was baseboard units and oil filled electric radiators; gas h/water and gas stove. Somehow I feel window/casement units are cheaper as when they tank you just go to Lowes and pick up a new unit for 150 bucks or even cheaper on ebay. Also, they allow you to run units in each room when you want, not cool whole house where you are not using space. I got a carrier for my new house 10000 btu, heats and cools for about 105.00 plus tax casement unit on ebay. |
