Green Forum, as in energy saving

dinorwig power station Wales.

Still got me ticket for working in sub stations etc. Doubt they let me in though especially if I take the zimmer frame with me.

Were doing all the sub-stations around London when they went bust.

I am not wrong for domestic installs, obviously for larger scale installs with lower feed in tariff rates and different on site usage rates then the figures will be different.

Of course ajstoneservices is right about the hidden costs of nuclear, so far the government has had to set aside £67.5 billion pounds for the decommissioning costs of the Sellafield site alone! http://www.bbc.co.uk/news/uk-england-cumbria-21298117

Peter how did you arrive at 2 x 15.44p?

 

[Peter1919]

On average domestic PV generators will use about half their generated electricity on site and export the other half to the grid but they get paid 15.44p for all of their generated electricity regardless of whether they use it themselves of not. So then the actual cost of the 50% of electricity generated which is exported is twice the FIT rate plus the export rate (currently 4.64p per kWh for new installs) they are also paid (which is usually estimated at 50% of what they generate as it is not worth the cost of installing an export meter)

Think of it like this if a tin of beans costs 10p and you pay a supermarket 20p for two tins of beans but they keep one of the tins of beans to use themselves then you have paid 20p or 2 x 10p for one tin of beans (ok yes you would complain about being charged for two but only receiving one but I think this makes the maths clear)

a 3.5kw unit will give saving and income of £630. quid year.

And I'm still paying for Ernie to watch TV.

Peter I'm afraid you're wrong.

A KWh generated by a >4KWp is paid at 15.44p x 1.

As you say then there is 50% deemed to have been exported at 4.64p KWh

The savings in KWh's costs no one but does save the generator, in my case, 13.88p but it is not a cost that can be added to generation use or export.

The cost of generation from a >4KWp system is 17.76pKWh when the export is included.

E.on, my energy supplier charge me 24pKWh for the first 700hrs and 13.88p there after.

Your sounding like a shiny suited salesman and I know you're not

That site needs updating

Peter I'm afraid you're wrong.

I never said it wasn't however you still miss my point that the approx cost of the electricity actually exported to the grid by a domestic PV system is double that as about half of the generated electricity they are paid for is used on site not exported.

A PV system owner is paid for the FIT rate for the 2kWh their PV system has generated in a day but they only actually exported 1kWh so the cost of the 1kWh electricity actually exported to the grid is 2 x 15.44p plus the 4.64p export rate.

For each kWh they export they are roughly being paid for one kWh they use themselves, so they are not only being paid for that electricity but also saving themselves the cost of having to import it fro the grid at retail price.

To be clear I support the FIT scheme and think it a good thing I am just clear as to what we are paying for the electricity it produces for the rest of those on grid electricity to use[/b]

And don't forget Mr Stone when you's playing with numbers that, 12% of my £600.00 quid sparky bill is a green tax, so another saving on top of the subsidies if you have PV.

Could be getting close to my 10 x now.

 

[ajstoneservices]

Your carbon tax is in addition to your generators costs it helps susidise your local power station and mine. And pay for the carbon trading sca....... scheme.

But you dont pay that if you have PV so another saving as I said.

Then it reasonable to say that they are paid (15.44 x 2)+4.63= 35.51p per Unit they export. Which is just over 7 times the 5p per unit, so 7 times not 10 times which is a large exaggeration.

12% of £600 quid is around £72 saving on top of the above.

I have PV and pay carbon tax. Granted I don't pay on it on the KWh's I generate and use.

Peter's wrong. See my explanation above.
