    This week 2 employees of a company contracted by SP Energy Networks turned up unannounced with a cherry picker on the back of a long base pickup truck. Normally I get a visit to make arrangements for access. They wanted access to one of my fields to replace a hazard warning sign on the pole in the field. They wanted to take the truck into the field to use the cherry picker but it is the wettest of my fields and I do not go in there myself with my tractor so as not to cause ruts The sign was about 10/11 ft up so I said could they not use a ladder to which they replied they were not allowed to. So reluctantly I allowed access, so they set up with hard hats and about the most heavy duty harness I have ever seen, set up the cherry picker and replaced the sign even though the original was very legible. In all a 5 min job took about 40 mins. I think both guys were immigrants one could not speak English and they spoke to one another in a language I did not recognise. I chatted to one who could speak English about the fact that they had a brand new pickup from from which I then gathered that a fleet of these had been acquired to go round replacing hazard signs. Talk of a sledgehammer to crack a nut. I am all for H&S particularly on agri properties but this was just too much.

    I still can’t come to terms with the price of electricity being linked to gas.
    We have no gas here, none anywhere near within miles. It’s not a choice for us.
    We are told every day how renewables are the cheapest form of energy.
    We are on a 100% renewable tariff
    Our electric cost more than doubled.
    It hasn’t cost them double to generate it.
    Is that 100% profit?

    We have a GSHP and an electric car
    It’s now cheaper to use heating oil and a diesel car.
    It feels like we are being shafted. The electric hasn’t cost any more to generate.

    Sorting out old paperwork came across an electricity bill from 20 years ago and we were paying 7p kwh. Based on inflation should now be 14p not 29p.
    I am manging to keep cost down having solar and battery and an EV now. I charged the car up last night added 200 miles for ÂŁ3. The petrol car we exchanged would have cost ÂŁ30 for that 200 miles. When not charging car I can charge the solar battery so replacing 29 p with 7p not counting efficiency losses.
    My October bill was ÂŁ4 for the electricity some months if been good for solar Octopus pays me. The fly in the ointment is the ÂŁ240 per year as standing charge hence my annoyance at the visitors this week. Not sure when I break even on the investment in the renewables, but more price goes up the shorter it gets.

    Absolutely. I know I ought to 'do my research' and understand for myself - but could some bright person explain it? AFAIK it's accepted by govt etc that it's wrong, enshrined in old contracts that made assumptions that are no longer true, and should change, but somehow year after year, govt after govt, no one can face the renegotiations, maybe another symptom of the modern crisis of corporate lobbying-influence? (which I think is the greatest medium-level threat in the world today, underlying climate-action failure, polarisation/democratic peril etc).

    The cost of electricity tracks the cost of gas because gas generation sets the marginal wholesale price. The wholesale price of electricity is set by the cost of producing the last unit of electricity needed to meet demand. This is nearly always a gas power plant with high marginal costs.
    End quote

    There has been talk of decoupling but I guess too much other stuff to deal with and no real incentive to do anything.

    I suppose you should be grateful that nuclear is not the benchmark price.

    Too right - but it could become so, as one of NESO's two 'pathways' includes ramping up nuclear (and gas) as a supposedly 'green' alternative to maximal offshore wind.

    " The wholesale price of electricity is set by the cost of producing the last unit of electricity needed to meet demand."

    That sounds absolutely bonkers. The price of all electricity sold is set at the cost of producing the final expensive marginal unit, which of course has to be using gas because all the electricity has already been used producing the 99.9% of non-marginal electricity?

    Where is the incentive to minimise costs if they automatically get the full price anyway?
    Having got their licence to print money they might as well stuff it all in the boilers!

    It's not completely bonkers, but ... Electricity is a hard real-time market - you absolutely have to have enough to go around at any given time. So if you paid people less if they reached agreement to sell/generate earlier, why would anybody agree to generate until everybody was panicking at the last minute? There'd be total chaos, and outages aplenty. It's like Black Friday guarantees - if you buy now and they reduce the price before December, they'll refund the difference. Otherwise nobody would buy anything in November.

    One alternative that is used for some low-carbon generators is Contracts for Difference pricing. In that scheme the generator is paid a fixed (index linked) amount for evey MWh they supply, which provides certainty for investment in nuclear and wind, for example. The amounts are set by auction when projects begin, and consumers end up with the bill or benefit at the end of the day/week/year/decade.

    Because anything they spend on costs comes out of their lovely profits! And if anybody makes huge profits, somebody else will probably start a lookalike firm to compete against other higher cost generators.
  5.  
    The pricing is all on the supply side with (until now) no control / options on the consumer side. If variable tariffs were more widely available the consumer would /could influence the demand which in turn would drive the generation and if the price differential was sufficient my guess is that you could almost negate the need for high cost generation.

    The standing charge is artificially high to in order to recompense the suppliers that took on customers from the collapsed suppliers, to ensure those customers didn’t lose money ( the moral hazard that creates is plain daft) and to reimburse the suppliers for the energy supplied but never paid for and to cover the costs of the social tariffs.

    Basically lots of additional spending that should really be direct from government, but that would mean higher tax rates and its much more convenient to hide it in the standing charge.

    Similarly the unit rates are higher than they need to be to cover the various eco schemes. Insulation , new heating systems etc etc.

    Just hidden state spending

    Posted By: Peter_in_Hungaryyou could almost negate the need for high cost generation
    But unless you change the system, you have to entirely eliminate the high cost generation before it makes a difference. At the moment - no wind for turbines, and lots of cloud so no sun for PV - there's no chance of doing without other forms of generation. Sad but true.
  6.  
    If it was all variable tariff then those with optional demand would / could defer to cheaper times (as some already do) and those with out the option to defer will have to pay the cost but will get cheaper power at other times (along with everyone else). This would decrease the need for expensive generation and I would expect for many would be the normal way of doing things and for those who don't care (or can't rearrange consumption) will pay the price.
    Whilst expensive (fossil) generation will be needed much could be done to reduce it and down the line I expect storage options to start to play a much bigger part.
    The system needs changing but I don't see the drivers to do that coming any time soon.

    IIRC the pricing is set every half-hour so everybody already benefits from cheaper prices at all times except peak (either by time of use tariff or by single price tariffs being set to account for the lower cost). You still need enough generator capacity to cope with peak demand which again IIRC is half-time in major football games when everybody switches the kettle on. You can't easily shift that demand, and thus can't much easily reduce generation. Especially as more people get electric cars and heat pumps and induction hobs and ....

    Posted By: djhIIRC the pricing is set every half-hour so everybody already benefits from cheaper prices at all times except peak

    But only those who bother to take account of the cheaper times. A bigger differential would be a better driver

    Posted By: djhYou still need enough generator capacity to cope with peak demand which again IIRC is half-time in major football games when everybody switches the kettle on.

    Which is where batteries or Pumped storage hydropower or some other instant demand storage steps up to the plate. Would (or when will) a bunch of batteries be cheaper than a replacement power station for one that is at end of its life?

    Posted By: djhYou can't easily shift that demand, and thus can't much easily reduce generation. Especially as more people get electric cars............

    Now theres one load that could be shifted. Getting home from work and plugging in the car IMO should be unaffordable.

    I wonder if the nub of the problem is caused by the break-up of the industry into the generators and the distributors? When electricity used to be generated, distributed and sold by the same organisation (eg local authorities?) then these problems surely wouldn't have arisen.
    Now it's a bit like a company being split into a production side and a sales side and having the two companies then operating separately and competing with each other. If the salesmen all suddenly decided to get their products from a different producer, or suddenly other sellers all wanted to buy instant electricity then there would be chaos.

    Doesn't it need smooth coordinated planning rather than instant competition between the different departments in the firm?
    • CommentAuthorArtiglio
    • CommentTimeNov 9th 2024
     
    The only way to have smooth coordinated planning is to have a monopoly supplier or two, the state being best placed to do so but as history and HS2 currently shows the state is hopeless at such things, it pays too much initially then politicians will want to divert money away from maintenance and repair slowly running it into the ground whilst staffing it with hugely expensive employees on pensions mere mortals can only dream of.

    As it is , in pursuit of met zero, we’ve had to offer high prices to encourage the investment, the costs of grid improvement and upgrades for such widely distributed generation is lost in the calculations but will add to the final end price to the consumer as will be the extortionate costs of storage.The wants and expectations of the average consumer are forgotten by “enthusiasts of net zero at any cost” and as such the eventual solutions won’t really work for anyone.

    The UK seems intent on paupering itself in a bid to be a net zero poster boy, but unlike Iceland ( tiny population and effectively limitless geothermal energy) or Norway ( again tiny population and huge sovereign wealth fund along with geography well suited to hydro) we have a large energy hungry population ( largely as a result of old housing stock designed and built in times of cheap plentiful power ) our energy reserves are the coal we sit but can’t now use, we’re not ideally suited for solar ( covering great swathes of high quality farmland with solar panels or biofuel crops hardly seems sensible) and given our population density wind needs huge amounts of capacity. The notion of cheap renewable electricity is wonderful but falls at the hurdles of distribution and storage. Gas is again pretty cheap and eventually ( when russian gas comes back to the market which it will) be cheaper still, it’s no coincidence that the pr campaigns for ASHP have gone quiet as you’d now need nigh on 5:1 efficiency to make it economically viable.
    The suggestion above that charging your car when you get home from work should be unaffordable is a prime example of what a work from home civil servant would come up with , (as they have no idea of the average persons life.) to solve problems the countries energy policies are creating.
    In a report last year it was estimated that the cost to the UK economy from excess weight and obesity is 98 billion a year ( or 3% of gdp) , if that figure is valid, convincing just half those so afflicted that keeping the fridge door shut is a good idea would save 49billion a year , enough for around 150,000 new social homes a year, or be able to spend 50k on upgrading a million older homes a year, or solve nhs and social care , take your pick. But the fat vote effectively controls the nation as no party wanting to tackle the problem would get votes ( unless you paid people to lose weight at some absurd marginal £/kilo rate) Sounds daft ,but who would have imagined HS2’s bat tunnel stories ( which you have to fervently hope aren’t completely factual on the cost front) and the conservation message that seems totally out of sorts with the way concerns over turbines and bird strikes etc are dealt with.

    Worlds gone bonkers.

    Reminder, the single biggest expenditure in UK energy history was the ÂŁ51.1bn that the Truss gov spent in just one year to subsidise the cost of foreign gas imports when prices skyrocketed post Ukraine. We're going to be paying interest on that borrowing for decades, and much of that money ended up in the coffers of despotic countries.

    https://obr.uk/box/the-cost-of-the-governments-energy-support-policies/

    The way geopolitics is going, the same thing is likely to happen again sooner rather than later. The faster we can wean ourselves off imported gas, the better. Lots of people still think we are still living in the 1990s when we had cheap North Sea gas, but it's pretty much gone now, get used to it. We are more import-dependent for energy than for food now.
  10.  
    And likewise coal reserves - UK coal peaked in 1958 and declined every year after that, it was pretty much finished by the time I grew up in a mining town in the 80s. That was long before we'd heard of net zero, it actually stopped because we'd already used it all up. I later lived in an oil/gas town and they're looking the same now.

    The world has completely changed. Nostalgia is a powerful political force, but politicians who tell you that we could somehow jump back to times when UK had cheap secure gas or coal, are not being straight with you.

    The new reality is that the UK is one of the most consistently windy and rainy places on Earth, with longer daylight hours in Summer than the Sahara. We are well placed to have the cheapest energy in Europe and sell it to everyone else, and the build-out of that industry is progressing faster than anywhere else except China and the US. Don't seem to be any votes in saying that, though.

    WiA,
    the problem is we have a totally inept political class both at Westminster and Holyrood. They can't plan, imagine what the outcome of proposed legislation might be and are completely out of touch with the average person. Too much has been privatised too big business who only think of the bottom line of each quarter. Until these thing change the UK/Scotland will only carry on on this course of decline.

    Today a couple of guys came this AM to check that the signs had been fixed properly. From several hundreds already done very few were at the correct height. The spec is 3m to center of sign so practically all will need redoing. When I queried why such precision it was so that when you look down a line of poles they are all visually in the same line. My goodness!! Apparently the training the sign putter uppers had was not good enough. The staff have been recruited from from Zambia and South Africa some 500 of them with more being recruited. So 2 to a vehicle, that is 250 new Isuzu pick up trucks with fitted cherry pickers. The auditors said I could have insisted that they did not go into my wet fields with the truck. There's where our standing charge goes what inefficiency.

    Don't know did not ask but they went into the field with a telescopic measuring stick. Having worked in a right 1st time mentality in manufacturing, no customers today no job tomorrow environment I just despair at the wasting of our money. Successive governments have destroyed SME's our wealth creators whilst the public sector threaten strike action if can't work from home. It is the wealth creators that pay their salaries there is not enough of them, so that is why we cannot pay for the services we expect. So Rachael robs Peter to pay Paul and puts the brakes on industry and business.

    Another visit this morning two guys a van and pickup with cherry picker. This time to move the sign to its correct position and wind barb wire around the pole. No doubt there will be further visit by a pair to audit it has been done correctly. It really pains me, organisation working on OPM whilst our wealth creators i.e those that make things struggle with overheads, not of their making, whilst we buy from China and other countries who can make things cheaper. Our industry pays the highest in the world for electricity according to the FT a little while ago. No wonder we cannot compete. Electricity and other energy sources are one of the biggest overhead of industry. Shame on our politicians if they cannot see that.
  12.  
    To be fair, those numbers in the FT were taken from the time a couple of years ago when world gas prices were very high because of Putin, and the ÂŁ was very weak against the $ because of Truss's budget disaster. UK electricity prices were linked to imported gas and it is priced in $.

    Fortunately, all those factors have improved now. Although the geo politics seem pretty dicey, if there's a war in the ME or tariffs imposed from the US then it could go bad again pretty fast.

    There do seem to be efforts to wean the UK off of imported gas for electricity by 2030, should see that in lower prices. Free electricity again last night on Agile because there was plenty of wind :-)
  13.  
    But I never did understand why they put notices on power poles, if someone is going to the trouble of climbing a power pole then a stern notice won't put them off?!

    I was reading today that labour politicians apparently agree with Dominic Cummings - that the civil service is incompetent. Much the same mentality in various industries that used to be nationalised, methinks.

    I suspect the electricty whatever-organisation-it-is isn't worried about whether people climb their poles and electrocute themselves. They simply want to be able to defend themselves against a charge of negligence if they do. "These chaps left a pole sitting there; it's an open invitation to climb it, m'lud".
