Electricity Costs A Cut And Paste

It's "Reality Check Time"

and below is a cut n paste from the San Diego Union Tribune
__________________________________________________________________________________________________________________________________________________

During the summer months of June 1 through Oct. 31, the baseline increases as energy demand rises across the state.

Customers in a standard SDG&E tiered billing system pay 27 cents per killowatt-hour in the summer and 23 cents a kilowatt-hour in the winter. If usage exceeds 130 percent of the baseline, the price then goes up to 48 cents per kilowatt-hour in the summer and 40 cents in the winter for that tier.

But if usage exceeds 400 percent — or four times the baseline amount — the rate jumps to 55 cents a kilowatt-hour in the summer and 47 cents a kilowatt-hour in the winter. This is considered the “high usage charge.”

Jones said the California Public Utilities Commission (CPUC) instituted the charge as a way to encourage customers to conserve energy. It applies to all ratepayers serviced by the state’s three big investor-owned utilities — SDG&E, Pacific Gas & Electric and Southern California Edison.


Yep, this caught me by surprise as well. But reality is blunt and unforgiving, whether I like it or not :)

  • Demand controllers are all the rage in limiting household KW /hr peak usage. A camp cannot limit peak usage, when the guest wants the juice, we have to supply it. So, when one of our 600 A CT metered measures on one hour a peak of 85 KW we pay the rate for the whole month as if that demand was there every day.
    The utility company has to build for the absolute maximum power draw. So do we.
    When you want a genny that will run all your house or rv needs, you have to get a big one, right, even though you may only need that big genny a few days a year.
  • The only item running in my condo is a fridge. So far, in seven months, it has cost $336.00 including tax, and all the other nice "extra" charges that get tacked on. The fridge door has been opened once...and the freezer twice.
  • CFE Rates for areas 1B:

    Basic consumption 0.697p for each of the first 125 kwh

    Intermediate consumption 0.822p for each of the following 100 kwh

    Excess consumption 2.802p for each additional kilowatt hour
  • I am rough guessing my first 75 kWh per month is 83 centavos per kWh

    Three point eight US cents per kWh.

    Of course the CFE bill is bi-monthly.

    The Dato Alto Consumo or DAC rate lasts a long time before dropping back to the original stepped tariff rate.

    CFE tried to eliminate the solar panel buyback agreement but then reversed course. Flat laying panels on the roof it requires about 9 kWh daily production by the panels to offset 24 hour use of a 5,000 BTU window air conditioner plus refrigerator. And it all has to happen during prime daylight - about 8 hours available in the summer. Lots of panels
  • The magic is in time of use (TOU) and solar net metering. I get paid for my on-peak energy at about 45 cents and use tons of power off-peak at 14 cents. I only generate half my energy and my annual bill is less than $100.

    Not sure this applies to MX but SC Edison was mentioned.
  • Not too different than CFE here in Mexico except that here once you exceed the "baseline" you pay the higher price for all you use and if you keep it up, it continues to be billed at the higher rate.

    SDG&E baseline for coastal with gas and electric services is 270 kwh per month during the summer and 276 kwh in the winter.

    Our "baseline" here in Zihuatanejo is 400 kwh per month.

    Here during the summer here our average usage is 60 kwh per week, using the AC a couple of hours in the evening. Their numbers are very reasonable.
  • I’ve moved out of energy investments. Too much volatility and politics.
