Watch those watts

Not all of us on OG&E’s Smart Grid are on time-of-day pricing, so I didn’t notice the official declaration that there are 25 peak hours per week: Monday through Friday, 2-7 pm. I did guess that peak usage might cost three times as much as off-peak usage, and apparently I was wrong:

Looks like this week off peak prices are $0.05 per kWh and peak pricing is $0.25 per kWh. Typical average price outside of this was around $0.08…so watch your usage so you don’t get a shock on your bill.

The standard-price tariff, at the moment — this is the Summer Price Period — is $0.084/kWh for the first 1400 kWh, $0.0968 thereafter, plus a flat $13. I pay a little more than this because I’m subscribed to the wind program; I hit 1400 kWh only once last year. According to the published neighborhood statistics, my own consumption is about 10-15 percent below average. I have no idea how much effect time-of-day pricing would have on me; I’m at work for at least half that period every day. Then again, if I don’t crank up the A/C until I get home, it’s going to run until midnight.

The variable-price tariff, incidentally, allows for a higher tier during critical (read: “we’re damn near maxed out”) periods, which may approach $0.50/kWh for those presumably-limited times.

    My energy consumption is apparently 10 to 15% higher than any of my neighbors. I think they must all be in San Diego. The furnace is off, the A/C is off, we seldom use the oven. The big lights are all fluorescent. The energy hogs we use are the water heater, the big TV, and the microwave.

    It’s probably all due to the cats playing with the welder after I go to bed. Except I don’t have a welder.

    I went back four months to see if this below-average spec was an anomaly, and no, it’s been pretty consistent. Then again, I have a relatively small house: the A/C is a mere two-ton unit.

    Your square footage is actually on the high side of what two-tons can be expected to do. I would have been tempted to go with two and a half just to be sure :) Also helps keeping the poor unit from running way into the night playing catchup after a 102 degree day. You know design is for 95 ambient outdoors and 75 indoors. Any higher than that out or lower than that in and you are on your own!

    Only 1060 square feet here; 2.5 tons is almost overkill. I usually leave the thermostat around 74; on the worst days, it seldom gets above 77-78 inside. (My bedroom fares worst, but I keep a fan in there to supplement the airflow.) Eventually I’ll have to replace it, mostly because parts supplies are drying up. The air-handler section is still performing decently.

    There is no hard and fast rule. The 500 sq. ft per ton of cooling is a suggestion. In actuality a Manual J should be done which comes in and looks at things like your sun exposure and how many windows and how much insulation and also takes owner preferences into account and then the results tell you exactly how much heating and cooling will be required to do the job.
    No two 1060 sq. ft. homes would be the same!
