predict your August electric bill, square footage, and your electric rate.

My prediction, $650, 2720 sf, electric rate 13.2- last month on 13.2, I get to go to 9.16 with Cirro starting August 16.
 
$240

3,280 sq ft

If I am reading my bill right, I pay 8.75 cents per kWh plus a fuel charge.

I have evaporative air conditioning for most of the house. The master bedroom has refrigerated air.
 
2600 sf....bill was $320. I have a pool and all kinds of sh** drawing power all over my house.

I think I was pretty far off, I just checked the meter again. Maybe closer to $300, would be awesome.
 
we've used 2000 kwh so far this month, I read it wrong earlier. This is great, now let's see, today is the 14th, the last day of 13.2 cents

So, we get a variable rate for one day, I'm guessing 10 cents, then we start with Cirro at 9.16 cents + $5.85 per month.

So, the math looks like (2000 X 13.2) + (1 day X 10.0) + (5 days X 9.16 + small fee).

meter was read on 7/20, so ....I will assume meter will be read on 8/20. 2000/25 = 80 kwh per day, and that much is $264, then $8 for tomorrow, then just round up to $8 for the rest of the days, 5 more days X $8 = 40,

264 + 8 = 40 = 312before taxes. estimate $20 in taxes gives me a bill of $332, wow that's incredible.

Now if that really happens, take that amount of electricity and use 9.16 instead of the 13.2 for the first 25 days, and that much is only $183. add the other 48 and I get a summer electric bill of $231 before taxes and fees, estimate $19 in taxes and fees and there it is a bill of $250.

Hey Orangecat,

The PV component is a 3KW system installed in 2006 under Austin Energy's (prior) rebate program. The AC component is a Lennox XC21.

Homebrew
 
wow, got my last electric bill from startexpower, 27 days, $297.

Considering this long string of 100+ degree temps in the metroplex, and having two teenagers at home using all of the electronics they can muster, I'm thrilled!

Now we go down to a record low, 9.16 cents a kwh + a fee, should be about $8 a day during the rest of the summer, then down to who knows how low during the fall.

Our new rate is approx. 70% of the old rate, so our 320 ish bill from a full 30 days in August would be low to mid 200s??

We may never see $300+ again, except for maybe January.
 
700 with the pool. I only run the pump three days a week, but it doesn't matter. House is 3300 square feet. In the winter it can get below 100 ..........summer........no such luck. New Goodman AC unit...............

I expect the electricity portion of the Austin Energy bill to be under $75 for 1500 sq. feet of conditioned space. We removed the siding (replaced with Hardy plank), blew spray foam open cell insulation in the walls and attic, sealed every opening for pipes or vents, added dual pane casement windows, two-stage high seer A/C which is a lower tonnage unit due to the increased sealing and insulation. Replaced the refrigerator with an energy star rated unit; all compact flourescent light bulbs.
We program the thermostat (Carrier Infinity) to go to 85 during the day, and down to 77 or 78 at 4 p.m. Works well.
I sure would have liked to get the solar set-up, and Austin Energy had a great rebate to go with the federal tax credits, but it still cost more than we could add to our major project.
Plus we haven't added a new roof yet, and that has to come before adding solar panels.
We got a zero interest loan for the refrigerator from Lowe's, a zero interest loan from Austin Energy for the a/c upgrades and insulation, and income tax credit for some of the costs.
Still, we spent more than just what the savings in electricity will justify, but we had to replace the siding to begin with, and the a/c was 28 years old, cheap builder grade windows, etc.
 
accuratehorn is on a good path here. Energy conservation is cheaper than energy production. We've tapped Austin Energy's rebates and zero interest loans a couple of times (insulation, solar screens, new HVAC).
 
$390 in Houston for a 3,500sf with pool running pump 8-10 hours a day, 600w landscape lights and keeping thermostat at 77. It was $800 last year same time. Big change is having the radiant barrier sprayed in and adding 12 inches of additional insulation. This is third month is a row that I'm seeing 30-50% reduction. Qualifier: 1/3 of the reduction is a lower rate.
 
1800 Sqf.

$250.

My subdivision in the north DFW area uses a co-op, and my electric bill is rarely over $150. July's bill was $250, I'm expecting the same for August. This summer has been brutal.
 
Accuratehorn, you might be able to combine your new roof with solar shingles and kill two birds with one stone.
 
is there anything worth doing to a 9.5 year old builder's grade house?

It's a Fox and Jacobs, built in 2001. 2 story house, roof probably about 1350 sf. New inside A/C unit installed two years ago. Pretty sure the culprit is cheap windows, thinking it would cost about 15k + to replace windows with good windows?

don't have near that kind of cash. What do you guys think about having some insulation blown in, maybe a solar powered attic fan?

Can you turn fan off in winter?
 
no, I'm in McKinney, 30 miles north of Dallas. more info., we have a two-zone unit. In the summer, during the day, I keep the upstairs at 83, the downstairs at 80, until it's evening, we want to be able to sleep, so at night the upstairs goes down to 77, the downstairs stays about 80, unless my wife gets wind of the temp.(she figures it out about half the time). She moves the downstairs down to around 77 in the evenings. - all of our bedrooms are upstairs.

All of this for a $300 bill, which I don't take for granted. I know it could very easily be $400 or $500. (With the new lower electric rate, I forecast that $300 summer bill to be more like $230.

The winter is going to be very interesting, last year we had the record $667 bill, I'm crossing my fingers and predicting $350 for a high bill.
 
@Orangecat: There are substantial tax credits for energy efficiency improvements. Austin has some very progressive rebate programs, perhaps McKinney or your energy provider has something similar.

Insulation and solar screens are not expensive and have very fast pay back periods. Replace as much of your incandescent lighting as you can with fluorescent or LED lighting. Reflective barriers in attics can make a huge difference in some situations. Energy star appliances as you replace your existing ones, a high SEER AC when it's replacement time.
 
August results are in:
Total KWH used: 1274
KWH generated by Solar PV System: 434
Net KWH: 840
Total bill for 8/3/2010 to 9/2/2010: $75.02
 
wow, that's fantastic. So, how much do you think this increases your home value? I guess it depends upon how many homes in your price range and neighborhood have features similar to what you have.

I would guess it might increase the value as much as 20%?

Even if you just do the math, right now a typical bill without your efficiences would be about $250? So, you're saving $175, annual savings = $2100 X life of house 30 years = over 60k.

Obviously you wouldn't expect someone to pay all of that upfront, but maybe at least half. I'm guessing that means your house gets a 30k bump when you sell it.
 
My bill came in and we used 906 kwh, I believe, and the cost was $71 something for the electricity part of the bill. The total bill with water, wastewater, drainage fee, and garbage was $135.
On the builder grade home, like ours, there are small things you can do that don't cost much, as pointed out. Sealing leaks to the outside would be the biggest gain, and maybe solar screens. There are companies that can test this, by hooking up a big fan to one door and closing everything else and checking for air exiting through water pipe entrances, poorly sealed windows, things like that. Just better seals around the exterior doors can stop big leaks. And there are some that use infrared heat cameras to check for cooling air loss with that technique. I think this is a couple of hundred dollars or less.
Our house was almost 30 years old and we had to replace a lot of bad siding, so we did the windows, insulation, A/C etc at the same time. But we had to discuss staying in the house for the next 90 years to make it pay off. You have to consider that.
If you are really sure you will stay where you are, the bigger ticket items can be more attractive to you.
