How immoral?

The government is apparently going to consider cuts in subsidies to solar panel installations. Apparently wind power is going to be targeted too.

Intense discussions are taking place about precisely how far to cut the small-scale solar “feed-in tariff” (FiT) which pays households and companies for energy produced.

Some officials in the Department of Energy and Climate Change are calling for a reduction in the subsidy by three-quarters, according to industry sources.

That would mean a fall from the current level of up to 43p per kilowatt hour generated, to as little as 9p per kWh – a move which the industry claims would be devastating. If the government follows past precedent, any change would not affect homeowners with existing solar panels.

So the lucky few wealthy people will continue to be subsidised by the poor. It's just a matter of how much immorality the government decides to retain in the system.

The Independent's headline is misleading.

Quote, "Offshore wind farms are set to receive more subsidies than previously planned in the next few years under proposals from the Government today. Under the plans, smaller-scale wave and tidal stream projects, which harness the flow of the tide, would receive many times more support than other types of renewable energy in a bid to encourage those technologies. While the amount of support to offshore wind will decline over the next five years, it will be cut less than had been planned, under the proposals put out for consultation today"

Land based renewable schemes are now losing out to off shore schemes.

One of my neighbours has literally, this week, had installed eight (approx 8x4) PV panels on his roof. The fact that his roof faces EAST seems not to trouble him. I figure the size of the installation must be around £10k and produce around 4kW - but I shall need to confirm this with him when it's finally completed.

I also figure, as he's a pensioner that he has been prevailed upon by one of these companies who install the kit for a nominal fee and then take the FiT - but as Willis would say, YMMV.

I'd appreciate any feedback from the blog (if that's OK with you Bish) that might support my argument that my neighbour is wasting his time and money - especially as the FiT is bound to be cut in the near future.

The forthcoming cut in the solar FIT will not affect those who are already in receipt - for them it will remain at 43p per unit index linked for the full 25 years. Those who are going to be hit worst are the hundreds of small companies who have been set up to install domestic solar and gone to the expense of attaining MCS accreditation etc.

Good to see tidal and wave finally getting the support it needs, even if it is ten years later than it should have been.

The thing that people tend to forget when considering installing PV cells is, suppose the installation fails after 5 years (water seals that leak + dodgy electrical connections) and there are no spares or service because the fly-by-night installers have gone bust.

After you discover there is no help from the solar industry, your local friendly licensed spark, if asked for his opinion, says that the installation is unsafe (because he was not involved in the original installation and can now see cash registers in his mind) and he advises that there is a risk of fire and/or electrocution etc. and the whole lot should be isolated. This he does in exchange for several twenty pound notes.

You may have to get the local electricity supply company to come in to put the meter back into its original configuration. They will do this in exchange for several twenty pound notes.

You then realise that all the kit will have to removed because the house will be unsellable with a duff power station on the roof and various computerised boxes in the hall cupboard.

Now, where are all the roof tiles that were removed? OMG, they went in the skip along with various bits of rafters and purlins that got in the way of the cowboys. Complete replacement of that part of the roof will not not cost more than a few grand, will it?

Then you find out that "Nuclear Free Zone" in which you live has declared the PV cells as toxic waste and the nearest licensed handler is located 500 miles away; his call out fee is £500 before he starts work. You get a estimate of £2,000 for the work (health and safety don'tcha know) plus call out fee plus council dump fees plus council supervising engineer fees plus police escort fees plus all bills at a local 5* hotel for himself and his entourage.

Yes indeed, your initial investment of £10,000 was money well spent.

The FIT for Photovoltaic installations is supposedly guaranteed for those who install them before the cut off date. Facing East is certainly not good but your neighbour should have been given a calculation of likely annual income and payback period that takes account of the orientation of his/her roof. Some of the installation companies will guarantee a minimum income from the panels and base the pay back calculations on this figure.

If the FIT is cut for existing PV systems the government will be breaking a direct promise to maintain and index link the FIT for 25 years and there will be a lot of angry people out there who have bought panels in the last 6 months to take advantage of this years advantageous FIT. It will also kill the industry as PV is not economically viable without the FIT.

However the FIT itself is not economically viable as it forces the electricity companies to buy electricity at 44p per kWhr when they can buy it from gas turbine generation for nearer to 4.4p per kWhr. Of course they raise the cash required to pay the FIT by increasing electricity prices for the poor, elderly and everyone else.

The FIT cannot be allowed to continue at its present rate as it will drive electricity prices up to truly staggering levels. I suspect that the government will significantly reduce the FIT for new systems from April onwards which will make the whole scheme even more expensive due to the extra administration involved in running differential payment schemes.

Yesterday afternoon I had a young man call at the door to tell me all about the money I could be making from Solar. And he wasn't alone - I saw three others calling at neighbouring houses, which seems like quite an investment in manpower from someone pushing this stuff.

Anyone who thinks that the government (and future ones) will stick to the FIT as originally agreed is being very naive.

Look what happened to the CRC monies envisaged by the Climate Change Act of 2008. This is the original version of the act:

"The CRC is a cap and trade scheme. At the end of each scheme year participants purchase and cancel emission allowances corresponding to their total CO2 emissions. One allowance = one tonne of CO2, CRC participants are required to plan and buy sufficient allowances to cover their annual CRC emissions.

All revenue raised from the sale of allowances in April each year is returned to participants in the form of a recycling payment. The amount each participant receives depends upon their proportion of emissions in relation to the total CRC sector emissions and their performance in a league table. The revenue recycling occurs six months after the end of each sale, in October."

The idea was that better performing businesses would receive money levied against the worse performing businesses - a carrot and stick approach to reducing emissions.

However, in March of this year the government declared that all allowances would instead be transferred to the general coffers and none of it would be recycled to the participants. Never trust a politician!

I prefer to see the limited sums available given to accelerating the development of wave and tidal generation, which makes a lot more sense in Scotland than solar.

@scotsrenewables

D'accord.

If wave and tide can be shown to be comparable in cost to other ways of generating power I am all in favour of them.

But if they, like every other supposedly 'renewable' source require vast subsidies to persuade anybody to be daft enough to build one, then thay should stay as drawing board projects, not concrete and kit.

There is no point in mpoverishing this generation because of some possible potential har that soem believe might befall some possible future generations if the night temperatures rise a little in 100 years time.

I rememmebr visiting the Rance Barrage in the late 1960s as a wide-eyed teenager. It is great! But I also note that it is almost the only one of its kind. In teh subsequent 40+ years very few have been built. There is a good reason for this....

The Salter duck arrived in 1974 with interest then in wave energy. On paper it is all technically possible but to claim that wave and tide make more sense in Scotland than solar sets a pretty low bar and may still be unachievable.

Maybe the Government will not simply slash the rate although it will drop for sure. Alternatives are taking away the RPI link and shortening the 25 year period. Both those would reduce cost substantially over the term and might reduce the drop in demand in the short term.

Oct 20, 2011 at 8:08 PM | Unregistered CommenterArgusfreak

Solar PV panels facing east or west work reasonably well, though not as well as south of course. North is a genuniely bad idea; south east is perfect acceptable. Note that if you use two roofs facing different ways (e.g., east and west), or just differentially shaded, you need to be carefulhow you wire things up.

If Snotrocket's neighbour is indeed using one of the schemes where somebody else pays then he is facing little risk. In standard schemes the homeowner pays nothing, and the installer keeps all the FITs and income from sales; the owner just gets free electricity during part of the day. So the installe carries almost all the risk.

Like EddieO I expect a massive cut in FIT rates in April, applying to new installations. We already know that there will be a small cut then, so the argument about differential tarrifs does not apply; I expect this will turn into a large cut (40%?). I also expect that the government will at some point reverse the favourable tax treatment of FIT income. If they go further than that then my investment will not be looking rosy - but then that's the risk we rent-seekers take.

Brownedoff is over pessimistic, at least if you use a decent installer. The damage to my roof is negligible (installing solar thermal by contrast had a more major effect). The system can be cut off from the mains by turning a single isolation switch. It may become valueless, but I don't see it becoming a major liability under any half plausible scenario.

Oct 20, 2011 at 8:11 PM | Unregistered CommenterOxbridge Prat

And I meant to add.....

The review is not news. The plan was always to scale the FiT back as the volume of installed systems grows. At the same time the wholesale price will rise and they would meet at a future date. A cut of three-quarters is not what was envisaged but is probably a more sustainable figure that is not quite as distorting. It was simply pitched too high. It will put more pressure to bring installation costs down which is good.

Going to be some very unhappy landowners if they miss out. But some happy consumers who will see their bills rise by a smaller, but still large, sum.

I do think the Govt might well be in a panic at the thought of the cost of FiTs appearing as an item on bills along with RHIs - announcement in December. Might RHIs be scaled back as well?

Solar at our latitudes is just not efficient, we all know that, but we waste our valuable resources on it.

I more than share your views on the need for a healthy and efficient UK nuclear industry, partly, I must admit by having worked in the industry.

Over the years I have witnessed the exodus of engineers from the industry as subsequent governments have bowed to the "green machine" and slowly throttled the industry,

The final straw, the one that really decimated our nuclear engineering capability was when our politicians endorsed CO2 CAGW. That was the end, all resources went “renewable” no bother whether “workable”. It only takes 2 decades to change a generational thought pattern.

UK Governments, planning for an inevitable 2 deg increase in temperature and mild winters saw an “energy gain” from AGW. Whilst any prudence would say plan equally for -2 deg C?

So we are left trying to ply multi-nationals with guarantees to build generation capacity, because we were convinced?

I have no argument about CO2 and its physical attributes, what I do not know and neither does anybody else is what Gaia does with CO2’s physical attributes.

So 2/3 decades on we are now faced with rebuilding our nuclear engineering capability, which realistically is going to take another 2 decades. Going to be fun!

Tidal Energy. The tide comes in twice a day. Twice a day it stops coming in and start going out. Twice a day it stops going out and start coming in. That's 4 times a day - called slack water - when it's not generating power.

Unlike wind the slack periods are predictable but nowhere in the world has anyone figured out how to keep the power flowing to the consumer.

"Tidal" is a nice word to slip into the conversation - but it's not a serious energy source.

Oct 21, 2011 at 1:48 AM | Unregistered CommenterJack Hughes

@JackHughes

The times of slack water are different all round the coast - i.e. when it is slack water in one area the tide is in full flood (or ebb) in another area. For example, today high water in Oban is at 13.40 while at Scrabster in the Pentland Firth it is at 16.20 - so during the short period of slack water in the Pentaland Firth tidal devices in (eg) the Sounds of Luing and Cuan or the Corryvreckan would be producing at maximum output. Tidal energy can therefore - unlike wind or wave - actually be used to provide a certain amount of base load power to the grid. There is no point in the next ten thousand years when tidal power could not be making a very substantial contribution to the grid.

Also, unlike wave or wind the amount of power that is going to be available at any one time can be calculated to the kilowatt, making its incorporation into the grid or integration with other power sources (eg pumped storage) much easier than wth other renewable sources. No constraint payments required.

Why not do a little more research before making sweeping statements ?

@Oct 21, 2011 at 1:48 AM | Jack Hughes

Actually there are perfectly practicable ways of dealing with the 'slack water' problem. The favourite seems to be two huge concentric coffer dams with various turbines mounted between the centre and the 'annulus' and between the "annulus" and the mighty restless ocean. I believe the Chinese are developing such a project.

I'm sure you can imagine how it might work. But (obviously) it would be even more amazingly unaffordable than a normal tidal barrage.

However, the big advantage of tidal is that you can sit down and predict with good precision exactly how much electricity it should produce at 7:30 pm on the 19th October 2035. Or whenever. The other advantage of tidal barriers is that they really upset the greenies because of the predicted effect of the changed water levels on the inside leg measurement of the British Standard duck. But that's a poor reason to pour billions into cockamamie schemes that a modern coal fired power station would outperform at a fraction of the cost.

If Scottish Ruinables thinks that wave and tidal are the way to go (perhaps having seen the writing on the wall for BigWind), I hope he re-mortgages his house and invests all the proceeds in these scams.

Your handle pretty much implies you are a bit 'eccentric' as we say diplomatically.
The north sea oil rigs were an outgrowth of technology developed since the 1940's and even before.
And, by the way, they involved mining something that had value- nice North Sea Brent, a sweet good oil.
Your disgusting tidal systems will damage estuaries, wetlands, migratory patterns of fish and other, less popular critters.
The windmills are proven bird killers and PV is great, as long as the sun shines and you don't need much power.
Enviros were great when it came to cleaning things up, setting aside land, decreasing toxins- you know actually helping.
But now big enviro is trying to pretend it is an industry, and all they can do is shake down tax payers for endless subsides of things that profit their friends, hurt everyone else and damages the environment.
And, by the way, not one thing you 'eccentric' people do will actually have any significant impact on climate. It will still ignore you.
But eccentric people do not really care about reality.

Hunter,

As usual with your ilk you will grab randomly at any argument. Semi-sub oil rigs were new technology, developed to meet the technogical challenges of the new drillig environment. The first purpose built drilling semi-submersible Ocean Driller was built in 1961, not the 1940s. Wind turbines are based on much older technology - so I am at a loss to follow your train of thought there.

As for your use of the word 'disgusting' to deride tidal energy - well , in what way does it 'disgust' you? Without debating barrages for the moment, current tidal development is focussed on sub-sea tidal turbines, which will have almost zero environmental impact.

Your insistence on the use of childlkie and emotional terminology like 'bird mincers' to describe wind turbines when cars, windows and domestic cats kill many thousands of times more birds than turbines only goes to further show the paucity of your arguments.

As to my 'eccentricity' - well, all I can do yet again is point you to the incredibly small, insignificant number of people that have signed the e-petition to repeal the climate change act.

For every action there is an equal and opposite reactiopn - but I don't think we need to panic even if we end up extracting a sizeable percentage of the tidal energy available.

Tides are caused by the interaction between the Earth's rotation and the gravitational pull of the Moon. The tides themselves introduce friction into this system and dissipate energy because of their drag on the coastlines and ocean floor. Even without any tidal power plants the tides are slowing the earth's rotation and causing the Moon's orbit to recede. However the effects are so small it takes thousands of years to be noticed. Tidal power plants would increase this effect in a microscopically small way.
