Selling the electricity you generate to the grid

Posted by Cathy Debenham on 20 August 2010 at 10:13 am

The feed-in tariff has made it simpler to sell the electricity you generate, but don't use in the house, back to the grid. It has set standard rates to be paid for electricity generated which are dependent on type of technology and size of system, and all exported electricity is paid at 3p per kWh.

Choosing your energy supplier is the key to seling excess. The reason it is simpler now is that under the previous system all the suppliers offered different buy back rates, and these had to be weighed up against the rates at which they sell electricity, so it was complex to work out the best deal.

Now all the big energy companies must buy back exported electricity from microgeneration, and some of the smaller ones have chosen to. If price is your key factor, then there's no shortage of price comparison sites available.

If it's important to you that the electricity you buy from the grid is from renewable sources you can use our guide How to buy renewable electricity.

I intend to install a 10KW micro CPH running on natural gas!  Any one know the best way to sell of the surplus electricity given that it's not renewable though it is pail green ?

Just need to bear in mind that unless an export meter is fitted, to measure exact electricity sent to the grid, 50% of the generated kW will be 'deemed' to have been exported.

 A excellent comprehensive explaination of 'deeming' and the implications is now on this site - post by Cathy on 25th Oct ; many thanks for that.
