Final changes to the Feed-In Tariffs for renewable electricity

Overall verdict: Some welcome improvements

Higher tariff levels

Some of the proposed tariff levels have been raised, especially for systems at the household scale. The tariff for small scale PV has been raised from 36.5 to 41.3 p/kWh and there have similarly been increases for small-scale hydro and wind.

The full list of tariffs is shown on our Tariff Levels Table. The tariffs for micro-CHP have also been included. Unfortunately, biomass tariffs have now been omitted so biomass power generation will now be rewarded only under the Renewables Obligation.

The Government says that while the tariff levels are designed to give a return of up to 8%, the benefit of index linking (see below) may take this up towards 10%. Private customers have the added benefit of the income tax exemption.

Index linkage:

The generation tariffs are to be index-linked to the retail price index and so will the export tariff.

Export tariff:

The price floor for exports has been reduced to 3p/kWh. However, the ability to opt out of this ‘minimum level’ and negotiate prices with energy suppliers is now no longer a one-off choice – you can decide annually.

Existing systems:

Sadly these remain ineligible, except those transferring from the Renewables Obligation (at the fixed rate of 9p/kWh). The Government has also ruled out refurbished and re-commissioned systems from being eligible.


The Government has deferred the start of degression until 2012. They have also made it clearer. We reconfirm that the tariff you get is fixed at the time the system is installed and then adjusted only for inflation. It’s only systems installed in future years which get a lower tariff.
