47p from April?

[AlanIOW]

I have just seen on the BBC website that the RPI figure for December was 4.8%, does that mean we will be getting a total of 47p/kWh from 1/4/12 including export at 50%?

... or how long before the gov't makes another (this time retrospective) U turn, and reduces the payments to people who are currently enjoying the higher rate? And before anyone asks about the legality of making a change in the future that countermands previous "law" - of course they can do it - they make all the laws up in the first place. A change like this in five years' time - who is going to pay any attention to a few thousand winging early adopters, then? (of which I am one).

I really, really wonder what I am supposed to tell my grand children, when they ask me why we just kept on *&%£ing the planet up, when we already knew better... Maybe that's for another post!

I wonder what you would tell your grandchildren when they ask whether the promises made by politicians can be relied upon?
Or, should they ever go into business, would you advise them to commit to a course of action that the government clearly wants to incentivise and see happen?

An alternative answer is to tell them that it is simply human nature for our species to c**p in its own back garden, sc**w its neighbours, and *&%£ the planet up. We deserve all we get - even if the rest of our fellow species here don't. When I was a kid my Mum told me the planet's other inhabitants would be far better off without any human beings at all (and that included me). Forty years later I still think she was right.

Parky, I think your mum sounds very wise.

Let us make no mistake, we are not trying to save the planet. The planet will shed us like an unwanted bug anytime we push things too far, then spend a million or so years cleaning up afterwards. It's us that need saving from ourselves, Mother Nature is big enough to look after herself (and kick our backsides when we get out of line, like any good mother should).

Mart.

Interesting.  Is the 3.1p export tariff subject to the same rate of RPI?  That would make it 3.2488 - would this be 3.2 or 3.25p?  I think you could guess...

3.2488 is still 3.2 to one decimal place

[AlanIOW]

Yes, they did round the Export down from 3.2488p to 3.2p, but they did round the FIT tariff up from 45.3784p to 45.4p, which with 50% export equals a total of 47p per kWh.

actually, that's mathematically incorrect

i think most likely they added:

45.3784 to 1.6244=47.0028

seems pretty fair to me

[tc847]

don, i think i disagree on both points.  sorry.
rounding (no need to specify down or up) occurs mathematically to a given decimal place by looking at the next digit (and only the next digit).  0-4 goes down, 5-9 goes up.
and the 2 elements are completely separate and therefore are both subject to rounding to 1 dp of a pence.

The link provided in the recent post shows all the numbers.  45.4p for generation and 3.2p for export.

With such small numbers and with inflation set to reduce drastically (well, that's what Merv keeps telling us) we may not be getting any increase on the export side for many years.  {If RPI is 1.5% then the increase on 3.2p will 0.048p and so will be effectively zero when rounded to 1dp}

ah yeah, your right, the rounding up bit i must have misread.  45.3784 is 45.4 to one decimal place. my bad.

[JohnS]

Once again I consider that the DECC is playing fast and loose with the rules.

Inflation is calculated as the difference in cost between a given basket of goods at two dates. 

In December 2009, the RPI basket cost 218.  In December 2010, it had risen to 228.4, an increase of 4.7706%, rounded to 4.8%.

In December 2011, the RPI basket as 239.4, an increase of 4.8161%, again rounded to 4.8%.

Now if we take the original export rate of 3p and multiply it by 239.4/218, we get 3.294495p.  If we multiply it by 1.048 twice, we get 3.294912p, both of which round to 3.3p

Only if we take 3 * 1.048 = 3.144, rounded to 3.1 and 3.1 * 1.048 = 3.2488 do we get a number that rounds down to 3.2

Hence in my original post, which is on another thread http://www.navitron.org.uk/forum/index.php/topic,16262.msg183953/topicseen.html#msg183953 , I said it would depend on the rounding.

RPI will have to be at least 1.6% to get it to round up next year to 3.3p.
