Just thought of a way of explaining how stupidly complicated the way of working out the feed in tarrif is.

I shall use an analogy.

Counting sheep's legs. (As if they were Kwh)
1. count the sheep.
2. There are 3 (THREE) legs on each sheep.
3 it is "deemed" that there are additional legs. to calculate the extra legs, count the number of nostrils the sheep has. The number of additional legs is 50% of the number of nostrils.
4. Add the number of legs to the number of additional legs. That is your FIT number of legs.

A Worked example.

I have 8 sheep.
8 sheep x 3 legs = 24 legs.
Each sheep has 2 nostrils.
8 sheep x 2 nostrils = 16 nostrils.
Additional legs = 16 nostrils /2 = 8
Add the aditional legs to the legs
8+24 = 32legs
QED.

The combined feed in and export tarrif is 17.22p.
Sheep have 4 legs.

Hi

It's not really rocket science, is it ? ... (Tariff+½Deemed)*Generation ... if you install an export meter & can find a supplier which will accept the readings it becomes (Tariff*Generation)+(TariffExport*MeteredExport) ....

Considering that many currently on deemed export will at some time move to metered export, how is this any more complex than any other method which could have been used ?. The next least complex method would probably mean publishing two FiT tariffs (Deemed & Metered) and the Export tariff, so three sets of figures to replace two.

I like eating sheep, but the analogy is wrong ..... Think of it from the farmer's point of view, after all that's what you'd be doing - farming photons. When selling your sheep you charge per kg and pay a transport company to deliver (which, of course is recharged to the customer). The transport company offers you a contract based on either a fixed (averaged distance) cost/kg delivered -or- a charge depending on distance. The size of the flock is up to you, as is the distance to the customers you deal with and the size of each sheep depends on the weather conditions which affects the quality/quantity of grass for that particular year ... so, flock=array, sheep=panels, kg=kWh, fixed transport=deemed export, variable transport=metered export, weather=sunshine ....

Our next delivery of lamb is currently growing nicely in a field a couple of miles away, so distance isn't really an issue there, nor is the complexity of tariff calculation ... :cool:
