Los Angeles energy rates = $0.31/kWh (tier 4). What's yours?

studio460June 18, 2013

Living in Los Angeles county leaves us with Southern California Edison electricity rates. We're currently at tier 4, at $0.31/kWh. We have no air-conditioning, no pool, no spa, and our lighting is 100% fluorescent and LED. Currently, our gas appliances include: clothes dryer, tankless water heater, forced-air heater. Every other appliance is electric, but all are recent models, and fairly energy-efficient.

Unfortunately, for both cosmetics and ease of cleaning, I chose a quartz-electric cooktop. Induction would've been more efficient, but all induction cooktops have an ugly aluminum frame. Ours is just a continuous sheet of black glass with touch-controls (no knobs). Boy, is that sucker easy to clean!

Back to the point . . . at an energy rate of $0.31/kWh, operating an electric clothes dryer can be an extremely expensive affair. Say you have a 240VAC electric dryer drawing 24A of current. Using the power law (volts x amps = Watts), running that dryer for one hour results in 5.76kWh of power consumed. Multiply that times a Los Angeles-resident electricity rate of $0.31/kWh, and you get a running cost of $1.79 per hour. If it takes two hours to dry your clothes in a condenser dryer (assuming a 24-amp draw, which I don't know if that's accurate, since no one publishes their dryers' actual current-draw), that's a whopping $3.57 per load.

Of course, a 120VAC dryer would cost less. Again, I don't know the exact current-draw of these machines, but let's assume a 15-amp draw, so you have, 120V x 15A = 1,800 Watts. That means a 120V dryer would consume 1.8kWh of energy per hour. At a rate of $0.31/kWh, that equals an operating cost of $0.56/hour. Better. For a two-hour drying cycle, that's $1.12 per load (note that our gas dryer does most loads in under 30 minutes, and our gas bill is something like $18/month).

Now, if you're running a 120VAC ventless condenser dryer for say, four hours, that would total $2.24 per load (for Los Angeles-area residents).

Ours are $.0466 per kWh for the first 10 per day, and $.1071 for each kWh after that. A nearby area has rates of $.027 per kWh.

Thank goodness for the Niagara Falls power plant I guess(!)

Ontario in on time-of-use for residential:
on peak: $0.118/kWh (afternoons in summer, breakfast/dinner time in winter)
mid peak: $0.099/kWh (breakfast/dinner in summer, afternoons in winter)
off peak: $0.063/kWh (7pm-7am year round)

We average b/w 14-18 kWh/day depending on time of year

As someone pointed out in another thread, you've probably calculated a worst case cost, but it's unlikely the electric heating elements are "on" continuously. Once a thermostatically controlled air temperature is reached, they should cycle on and off to maintain the temperature.

Our two-month average cost was $0.05650 which comes out to $4.18 per day. That's less than the cost of a latte. So, stay home for coffee and pay your electric bill without even trying.

OMG! I knew we were getting screwed! We pay $0.31/kWh for our "tier 4" portion (about 30%), and our total usage this month is 809kWh. Approximately 75% of our usage is over the baseline "tier 1" rate (292kWh), as are most households. But, even though our highest usage is during off-peak hours (between 8:00PM and 2:00AM) we get stuck with a significant portion of higher-tiered rates. Our previous month's bill was $192.80. No pool, no AC, all fluorescent/LED.

Our rate here in Houston last year was 8.2 and this year it's 9.0 per KWH. We installed a new central a/c unit and even though it has been hot we only used 407 kWH last month.

A few years ago it was 0.17 per KWH.

I pay a market rate for the supply, usually about 8-9 cents per kwh, then the utility (Con ED in NY) charges me about 12 cents for delivery.

809 kwh is a lot of energy for a residence with no heating or cooling and all CFLs. Something is using power, you should investigate carefully to see if the wiring is right and the power company is reading the correct meter. Don't laugh, I used to work at a power company and meter mix-ups happened all the time.

Thanks for your reply, curiousshopper. Yes, we really need to perform a total consumption audit. That said, even though we have no AC, or other large-appliance loads, we have a lot of stuff running.

Here's what's powered-on 24/7:
x1 24.1-CF refrigerator/freezer [557 kWh/year]
x2 42-Watt DVRs
x2 28-Watt non-DVR set-top boxes
x1 84-Watt19" LED TV (security monitor), plus five more to be installed
x1 security DVR
x6 security cameras
x1 cable modem/WiFi/router
x4 routers
x5 24-Watt LED desk lamps
x2 30-Watt HDD power supplies
x1 Dynalite battery/inverter charger
x1 Anton-Bauer charger

Here's what's on anywhere from 4-10 hours/day:
x3 24-Watt LED desk lamps
x6 40-Watt T5 fluorescent strip lights
x2 36-Watt T12 fluorescent strip lights
x2 24-Watt T12 fluorescent strip lights
x1 525-Watt 65" LCD TV
x1 100-Watt home theater audio system
x1 289-Watt 50" plasma TV
x1 80-Watt home theater audio system
x2 280-Watt iMac computers
x2 180-Watt 42" LED TVs
x2 160-Watt game consoles with internal HDDs
x2 laptop power supplies
x1 230-Watt PC
x1 135-Watt 13" CRT TV
x5 40-Watt outdoor CFLs

Additionally, there's dozens of 12VDC power supplies strewn around the house supplying power to musical instruments and other audio support equipment. The instruments are usually off, but the power supplies are still plugged-in (I really need to start powering these power strips down regularly).
