Finally the Government has published its thinking around a revision of the Feed-in tariff scheme. The press release was published on the DECC site today, 9th February 2012.
We have divided up the implications of this FiT Review announcement into three sections. The first looks at the definite changes to Solar PV, the second at proposed changes to Solar PV, and the third at proposed changes to other technologies covered by FiT (wind, hydro, AD etc) and more general FiT administration issues.
Definite changes to Solar PV
- A new set of tariffs will be introduced for all systems registered after 3rd March 2012 ie. 21p/unit for domestic scale installations. The Ministerial statement says “The new tariffs are designed to apply to all installations with an eligibility date from 3 March onwards.” See our article "Is Solar PV worth considering in 2012?" for more detail on these.
- From 1st April 2012 properties should achieve an Energy Performance Certificate rating of level D or above to qualify for the full FiT tariff. That means older properties that tend to leak energy are unlikely to be eligible for the full FiT so will significantly reduce the market for solar PV.
- From 1st April DECC will change the multi-installation tariff rates (which are 80% less than standard rates) will now only apply to projects involving 25 installations or more (rather than 2 or more) – this is aimed at helping community schemes.
- A new higher tariff for microCHP units will be introduced to incentivise take-up of these.
- There is, as yet, no clarification on the situation for people registering PV systems right now (Feb 2012). “The government cannot give certainty on tariff levels to people who install solar panels with an eligibility date between 12th December 2011 and 3rd March 2012 due to ongoing legal proceedings. DECC is appealing to the Supreme Court and has until 21st February to lodge its case.”
Proposed Changes to Solar PV
DECC are consulting on their Solar PV changes (Document 2A) which requests feedback by 3rd April. These are the highlights from the consultation document together with some of our thoughts:
Their proposed PV tariff table from 1st July 2012:

The DECC consultation document (2A) outlines the detail of Options A, B and C which are based on different scenarios. The stand-alone rate would apply for those properties which do not achieve an EPC rating of D.
- DECC would like to introduce a new set of reduced tariff options from 1st July 2012. This would be based around a much more flexible PV tariff system that could take account of rapidly changing market conditions. This is likely to include a 5-10% cut (called a ‘degression’) every 6 months together with the ability to cut the tariffs even quicker if demand starts to rise significantly (with a 2 month notice period). We would suggest the previous hikes in demand are highly unlikely without major falls in the price of PV panels given the scale of cuts to the tariffs.
- DECC are proposing to cut the FiT for PV from 25 to 20 years.
- DECC are proposing to review the export tariff currently at 3.1p/unit – this could potentially be increased although they would then decrease the tariff to keep returns consistent.
- DECC are proposing to review whether tariffs should be index-linked and increase automatically each year or ‘flat’.
- DECC propose to reduce the solar PV tariff for non community-owned multi-installations to a level equivalent to the stand-alone tariff from October 2012. As we understand this will dramatically affect the business for those offering commercial companies offering ‘rent-a-roof’ schemes
Proposed Changes for Other Renewable Generation Technologies
A further consultation (2B) document has been produced covering other FiT technologies and general FiT administration. The closing date for feedback on this is 26th April. Here are some of the highlights.
Proposed tariff changes – note they are proposed to be introduced from October 2012:

Note, one of the major potential loosers is the small wind sector where those installing wind turbines between 1.5 kW and 15 kW after October 2012 could get their tariff cut by 25%. Look out for a major spike in installations of small turbines over the summer if this is confirmed.
Annual Degression – DECC propose ‘automatic degression’ of tariffs and capacity triggers across all other technologies. They have particular concerns over a potential rapid increase in the number of micro-wind projects..”there may be some budgetary risk from other technologies that can be deployed quickly such as micro-wind installations. We propose that from April 2014, all tariffs should be subject to a minimum degression rate of 5% per year.”

Energy Efficiency Measures – linking these in to buildings so smaller scale generation projects based on building mounted wind turbines and microCHP could be dependent on the energy efficiency of a building.
Use of Second-hand Equipment - DECC are considering whether ‘second-hand equipment’ could qualify for the FiT and, if so, how should the tariff be reduced to support this? If this is brought in it would have a big impact on the market almost instantly generating a second-hand marketplace for used and refurbished equipment.
AD – Tariffs are frozen. DECC has concerns around environmental risks associated with purpose-grown crops for AD plants.
Wind - Tariffs for 1.5kW to 1.5MW wind installations are set to provide an approximate 8% rate of return for reference wind installations located at sites with an average 6 m/s wind speed. This target rate of return at the high end of the 5-8% target rate of return is justified because of the portfolio risks experienced by wind developers.
Hydro – “Recalculation of tariffs using the revised estimates based on an 8% rate of return would result in a profile of tariffs that was very similar to the existing tariffs.”
MicroCHP – “..we propose to raise the support level to 12.5p. This increase will allow a rate of return for μCHP comparable to other low carbon domestic technologies.”
Community Energy Schemes – DECC would like to develop clearer ideas on how to define a community energy project
FiT Accreditation process - “We recognise the value of a preliminary accreditation process, along the lines of the RO. We believe that preliminary accreditation should be offered to wind projects over 50kW and all hydro and anaerobic digestion installations i.e. those that are eligible for ROO-FIT.” This would suggest that DECC are considering some way that projects can get a tariff guarantee offering financial certainty earlier in their project life-cycle. This would certainly be very helpful.
General Admin of FiT - DECC are considering greater powers to remove installations from the FiT register where, for example, they have been unlawfully erected through not getting planning permission.
