    I've written that I think TOU should be compulsory in order more properly to price electricity and encourage peak shaving. Now I'm putting my money where my mouth is. TOU billing will start from 3/1. I can go back to flat rate at any time, possibly subject to a penalty, but then I can't sign up again until the next year.

    Maine PUC finally approved a Time of Use supply fee whereas before it was only on delivery. Average prices per kWh, based on my latest annualized consumption (supply price will vary by month), will be:
    - $0.0985 off peak (8pm-7am, all weekend, maybe holidays, not sure about the supply?)
    - $0.17223 shoulder (12pm-4pm weekdays)
    - $0.186101 peak (7am-12pm and 4pm to 8pm weekdays)
    (Yes, that's right, shoulder is in the middle of the day here. ;))

    Flat rate (supply plus delivery) would be $0.134121/kWh. That's down about 0.6c/kWh as the standard offer flat supply price is going to drop. I guess it's cheap shale gas.

    I've had usage stats online from October and it seems that when we aren't in the 2 A/C months our use is fairly flat, with peaks for cooking, laundry and the dishes. I should be able to keep the laundry and dishes off-peak. We'll see how much the summer usage change hurts, especially given that we don't electric dry much in summer.
    If my usage were completely flat, based on the previous year and the prices a rough calculation says my principles would cost me around $25 per year.

    Here are the full pricing schedules for March 1 2013 to February 28 2014.

    Haha! You have TWO AC months? We're closer to two heating months, and summer peak load is noon to 5 pm.

    Just got my January bill. (used to be aligned with the months, but now it's on the 20th. :confused:)
    2196 kWh, compared to historical average 3700. Last year was lower, at 1882, but this is close. I LOVE this new heat pump that works down into the 20's. I didn't switch it to resistance heat even once, while i used to run it most of the winter with the old one.

    Oh, maybe my improved attic ventilation is hurting a bit in winter. I'm sure it'll be a net positive when summer comes around.

    Your favorable experience with your new heat pump is similar to my own. We have seen at least a 15-20% reduction in our power consumption with our newer high efficiency unit. As you mention, limiting the use of the resistance back-up heat is very important as well.

    Our unit has a lockout control on the back-up heat linked to an outdoor sensor which can be adjusted from the thermostat. (Unfortunately the owner instructions do not explain how to change the setting so many people are stuck with whatever the installer set). I was lucky enough to get the installer's instructions so that I can adjust mine as I see fit. Normally I have it set at 35F but can lower it to 30F or 25F if conditions are dry enough that frost is not too much of an issue.

    As far as your additional attic ventilation is concerned, I doubt it will hurt your heating situation. If your insulation is adequate, the attic should be virtually the same as the outside temperature. The only issue I can imagine is if you have air leaks around access panels, electrical boxes, etc. in your ceiling. (I know some people remove "whirlybird" vents in winter so that there isn't as much suction of air through the attic.) For summer, adequate air intakes at the eaves or gables are just as important as "outlet" vents at the ridge so you encourage a good convection flow of air through the attic cavity.

    my electric bill for March 2 2013 to April 2 2013 was twice as high as last year.

    Still in a plateau...
    1000kwh every 2 months.

    Hope to turn off the heat soon.

    Need new idea's for elec efficiency.

    My last electric bill was 572 kWh for 63 days. This mth. I have decided to heat my home with a air source Heat pump rather than a 80% efficient gas furnace. My gas bill runs me $75.00 per mth.. The gas furnace will look after temps lower than -10C. I am hoping to come in at the year end with a savings? At least there will be less emissions from the gas furnace.:) I was going to install a air conditioner anyway so am killing two birds with one stone. H

    Just 12 KWHr per day- $1.20/d
    In April we are lucky to reach 30/d-$3.00
    But in the hot months
    June July Aug we are happy to get 55/d=$5.50 a day.

    Eventually we'll get a more efficient AC system-the ductless type-and better windows

    Our house is 1700 sq ft-NOLA-hot humid-someone is always home

    - We don't have to do too much cooling, just hot days in July and August. If we got a small A/C unit for the living room it would help make it more comfortable in the hot summer days, but overall just managing windows and closing curtains makes things good enough.
    - We heat with, bleargh, oil and for 2012-2013 have paid $381/mo for the heating. :-O
    - I'm trying not to replace the relatively old furnace until natural gas is available: Augusta is getting it, and I'm hoping they'll make the hop to our city since there are two colleges and a hospital that could be a good potential customer to get things started while they do residential build-out. Yes, I know, fracking, groundwater etc, but biogas from sewerage, farms, waste, Pine Tree State etc.
    - We have a leaking indirect 41 gal water tank that should be replaced within the next 2 weeks and that should cut both water and oil consumption.
    - I know there are things we can do improve insulation. I think I'm going to see if I can find a good auditor to get a full list.

    ItsNotAbout- even factoring in fracking/groundwater etc
    Gas sure beats oil and KILLS coal in "green-ness"

    Poor coal industry-bitchin' about Dems Greenies killing them
    when it actually is their fellow fossil fuel buddies/enemies producing NG
    that is putting paid to coal.

    They should be blaming their buddies Bush/Cheney for modifying environmental laws to simplify legal injection of fracking fluids. Without that change coal is still king.

    phoebeisis Well-Known Member

    Well Bush Cheney were OIL BIDNESS guys
    So Coal-ain't king.

    Screwed by their FOSSIL FUEL buddies.

    Maybe there will be some break thru that will boost coal's future.
    Some way economically capture CO2.
  16. ItsNotAboutTheMoney

    ItsNotAboutTheMoney Super Moderator Staff Member

    Coal with carbon capture isn't that expensive, it's just not cheap, so it loses to cheap natural gas, since natural gas plants can be small, cheap and put anywhere you can pipe the natural gas. Plus, every kW of natural gas helps you add a kW of renewables economically.

    But coal will still grow unless something radical happens in solar and batteries.

    A pretty good April - June @ 13.88 kw/daily. This is my lowest bimonthly since 2009.
    Thrilled the heat is finally off and the A/C is only on twice so far.

    for the year, I'm still trending upward.....:confused:
    + 114 kw for the year to date.

    But I solved some issues with my daughters computer not shutting off.
    No matter what setting in Windows.

    It's tough for you to judge since you use electricity for heating. But nice work on the computer, since the inability to go in full standby can waste lots of power, and cause you to use more to balance the generated heat with A/C in summer.

    If you could find heating days data for your area, you might be able to determine what's heating and what's apppliances and then work on the two issues separately.

    Thanks INATM,
    But my heat is gas baseboard. Only the pumps and electronics were active electric.
    It was a late cold wet spring here.
    That kept the system on much later than last year. AND now has me running a dehumidifier in the basement.

    Computer not shutting off was keeping speaker system going also. Damn those vampires.
    Now the Smart Strip is working again.

    My family is the cause of our upswinging usage.
    Teenagers summers are more at home last year over previous years.
    I expect the same this year.
    But college is coming soon, That should lower our electric costs.......:eek:

    As for the power company. We are up to $0.22225 a kwh. A new high.
    Guess they need more for the Hurricane Sandy and Super Snowstorm of the last year.
    Or the tax rate on elec is up. Probably both.

    Progress is to be measured or Losses will be counted.
