    Electricity Pricing Policy is very strange as the more you use the cheaper it get or the easier it is to switch to a cheaper supplier.

    This is crazy at it does not encourage savings

    Shouldn't it be "The more you use the more expensive it becomes" -- this could also apply to other fuels

    Should there be a minimum tariff below which no supplier can go? and a free band above which it costs more to encourage low use.

    The higher rate for the first X units is because they've absorbed their standing charge into the unit rate. It's a marketing exercise so they can say they don't have a standing charge.

    As for pricing units to encourage conservation, electricity companies don't have any real incentive to do this so unless the government interferes it's not likely to happen. Which is a shame, and a clear case of examples where governments meddling in an otherwise free market would bring about a better result for society as a whole.

    While electrical energy is as cheap as it is, there is little incentive to reduce usage anyway. You can play around with the pricing structure as much as you like but it really comes down to how much you use. The price is set by production which is a mix of long term fixed price, auctions and sometimes desperation.

    Personally I would like a standing charge and a fixed unit price, fortunately as we head towards the marvels of smart metering (not yet working anywhere in the world but some places are close), we are going to get much more confusing tariffs.

    Electricity is more expensive than other forms of energy.

    Diesel's about 14p per kWh, which translates to about 35p/kWh of useable energy. Electricity is about 11p/kWh. Use cheap rate electricity and a good heat pump and you could pay about 3p/kWh of useable energy for heating.

    Heating Oil/Kerosene is about 6.6p/kwH after boiler efficiency is taken into account...

    Point taken about the heat pump but perhaps next year someone will make a heat pump that runs off Kerosene.

    There are heat pumps that run off nat gas but not for domestic settings as far as I have seen. There have COPs of around 1.6. So at 4.5p/Kwh natural gas would reduce the cost to 2.8p/Kwh.

    If minimum wage is between £2.65 and £6.19 an hour, electricity is really cheap when you think what it can do.
    Yes there are cheaper forms of energy, just as there are cheaper labour rates in other places.

    Completely agree. Reduce the price of the initial X Units (helps with fuel poverty) and raise the price the more you use. The Standing charge is just a stupid money making scam. How we still put up with it I do not know. Do you pay 'line rental' for your mobile? :devil: so folk'll argue you do in the price, but I can still use the phone without paying more. All standing charges should be scrapped.

    I don't agree with the unit price getting cheaper the more you use, though have no problem with the standing charge as long as it is just an infrastructure charge and not used to make excessive profits or offset the unit charge.
    I think I get charged 18p a day for mine, so that will be about 70 quid a year with VAT.
    Just looking at last bill it seems I now have just 2 bands, Day at 15.24p and Night at 5.77p per kWh.

    We are used to fixed charges and variable charges on usage, take road fund license and TV licence, RFL is fixed but banded, TV is fixed and both are regardless of usage. Excess baggage surcharges are a usage driven price though airport tax is a fixed fee.
    My mobile operator does not pretend to give me anything free, just states for £7.50 a month I can use 250 minutes of voice calls (to certain lines) and 2500 texts before I start paying charges, never had to pay extra on my latest contract so no idea what the charges would be for going over the limit.
    Bank charges are another area that has a mixture of fixed and variable charges.

    It really does not matter to most people how their bill is calculated as it is the overall price that is important, as that is what they pay. Would be interesting to find an average street, with average people and put them on different price plans and see if it really makes any difference.

    But for £70/year I get a reliable, consistence and safe electrical supply into my house, engineers working around the clock to keep it that way, investment in infrastructure and service, development to reduce usage and emissions, free or highly subsidies insulation and a moron in a woolly suit at the Olympics.

    I think that fuel poverty is not caused by energy prices but from low wages. Should we really be expecting some households to be living on 40 to 60% of the median wage, there is not that kind of difference in energy pricing.

    Over here, the first 30kWh/day is at Can$0.0532 per kWh and thereafter Can$0.0751 for consumption in excess of 30kWh/day - so there is an incentive to stay below 30kWh/day

    Paul, that's why my brother was in such a panic to get his heat pump fixed last winter!

    In the depths of winter, though, I've seen our consumption go to around 110kWh/day - this is when it's in the mid -20C range and the auxiliary heat kicks in.

    Posted By: JoinerPaul, that's why my brother was in such a panic to get his heat pump fixed last winter!


    Which goes to show that heatpumps work fine below 0C. Does your brother have the dual-tariff rate? This is where you pay roughly half price per kWh above -12C and four-times as much when it's below (and then you're expected to use another heat source).

    Neat. I didn't realise this was done already.

    Suppose we all lived in passivhauses using, say, 6 kWh per day most of the time but an extra 6 kWh per day during cold spells. I think the electricity companies would need to introduce something like this to pay for the capacity needed for the peak but not used the rest of the year.

    Design and lifestyle implications would be interesting, too. E.g., it'd strongly motivate the use of significant amounts of thermal mass to ride out short cold spells with little or no heating. Some of the spare capacity could come from not plugging in plug-in hybrids during the cold spell - effectively using cars' fossil fuel engines as extra energy source capacity.

    Of course, the generalization of this is full smart metering where what you pay is a directly related to the spot price of electricity. E.g., -12 °C and still would be more expensive than -12 °C and windy.

    Damon is the expert on this, but the way I understand it is that with our 'competitive market' it is already going on to a certain extent, just that the troughs and peaks are flattened out for the domestic customers to avoid a price shock.
    Demand can be predicted to within a couple of percent and then the generation companies offer to supply (other than what they have on long term contract), if they under supply they then have to buy in from companies over supplying, there can be a big price difference here. This is all done on a relatively short (3.5 hour) timescale so that demand and weather can be matched pretty well. What can happen is that some generation is neither auctioned or used, but kept aside just in case there is a need for it (a generation facility going off line), the thinking being that it is cheaper to keep the reserves spinning and not use them than buy in when disaster strikes. This lowers overall efficiency, and by definition profitability, but gives better certainty and reliability. As consumers we like certainty and reliability, not many of us would want a cheaper supply for an unknown numbers of hours a week (though it may be a good way of regulating what we use).

    It's not happening for domestic/retail customers in the UK yet, AFAIK, though it should IMHO.

    In the US market there do seem to be retail customers that can access such (de-fanged) dynamic time-of-day charges separated out from infrastructure and/or otherwise incentivised to move their loads around and trim back at demand peaks. (Most people in the UK have access to something like E10 or E7 if they want it, and the timing may be slightly flexible even if the rates are binary.)

    Most large customers in the UK and US will almost certainly have access to a number of non-flat plans based on HH (half-hourly) pricing or similar.

    The EMR (Electricity Market Reforms) in the pipeline are about separating capacity from output on the generation side.

    One has to understand that, over here, most people heat with forced air - the reason being that this allows them to install an A/C system into the ductwork that also serves for heating. So the classic set up is some kind of fossil fuel "furnace" with ductwork that includes and A/C evaporator.

    The conversion of these people to using a heatpump for heating is easy - they get to keep their existing fossil fuel furnace and swap out the A/C for a heatpump (which looks identical to an A/C unit anyway except for the addition of a reversing value and maybe an extra TXV and refrigerant filter - cost is not the different between the two). All you need now is a control to switch off the heatpump at -12C and turn on the fossil fuel furnace. Easy :)

    Paul in Montreal.

    p.s. it's very rare here to have combined heating/hot water heating systems

    According to http://www.hydro.co.uk/Cost/

    only 50% of the consumer bill is the variable wholesale price of generating electricity

    the other 50% is more-fixed stuff - distribution, FITs ROCs, admin, VAT, profits....

    Just got this from big brother in Montreal...

    "Yes, That is pretty much the way it goes. If you have an alternate source for heating then you go on a 'Dual Heating Plan'.

    "We have a heat pump which heats the house in the winter down to -12C. When it gets below that it automatically switches over to oil or gas (we have oil) and electricity costs about 4 times as much. Hydro sends an FM signal to our panel box and an amber light comes on. When that light is on we do not do any washing or drying and B***** tries not to use the oven. There are two sets of dials on the meter. One for below -12 and the other above. It saves a lot of money over people who only use one source for heating. I believe if you only use electricity for heating that there is a special rate for that also. Almost all of our electricity comes from renewable sources like dams in remote Northern Quebec, wind farms at Gaspé at the mouth of the St. Lawrence and one atomic energy plant which they plan on closing. We have so much surplus electricity that we service Vermont, New York and parts of Ontario."
