Feed-in tariffs in the United Kingdom were announced in October 2008 and took effect from April 2010.[1] They were entered into law by the Energy Act of 2008.[2]

Scope[edit]

The Feed-In Tariff applies to small-scale generation of electricity, paying a fixed sum for eligible technologies. Note that despite being called a feed-in Tariff the payment is for each unit of energy generated, and not for electricity fed into the grid.[3] Electricity fed into the grid is called exported electricity, and receives a small additional export tariff, currently (June 2013) 4.5p per KWh. Costs for the programme will be borne by all British electricity consumers proportionally: all consumers will bear a slight increase in their annual bill, thus allowing electricity utilities to pay the FIT for renewable electricity generated at the rates set by the government. Payments through the mechanism are intended to replace the ROCs available through the Renewables Obligation for small-scale renewable energy generators and is based on a few key elements:

  • The tariff is available only to renewable sources producing up to 5 MW power. Specific rates are set for different technologies and at different scales of installation for those technologies. Generators of renewable electricity larger than 5MW remain eligible to earn Renewables Obligation Certificates within the existing Renewables Obligation quota mechanism. To prevent companies from moving large scale (for example big wind) projects from the ROCs to the Feed-in Tariff programme, a number of anti-gaming provisions have been inserted in the policy design; this should avoid the breaking up of bigger projects into several small ones, to fit within the 5 MW energy size cap.
  • There are several other qualification requirements[4] including: certification under the Microgeneration Certification Scheme and the REAL Code for systems up to 50 kW; the use of specific metering standards; and systems being installed no earlier than July 2009. Energy efficiency requirements were added in March 2012 for buildings fitting PV systems under FITs.
  • The contract term is 20 years, 25 years for solar photovoltaic projects: this means that, starting from 2010, British providers of Wind Energy, Hydropower, Energy from Biomass and Anaerobic Digestion eligible for the FiT scheme will be rewarded with a tariff rate guaranteed for the next 20 years - 25 years for Solar PV generators.
  • The tariff made available to generators will be subject to degression.[5] That is, the tariff level available for new generators will decrease annually. The rate of degression will vary by renewable energy technology. The price for individual renewable energy generating plants is fixed once the plant becomes operational.
  • Costs for the programme will be borne by all British electricity consumers proportionally:[6] all consumers will bear a slight increase in their annual bill, thus allowing electricity utilities to pay the "Feed-in" Tariff to renewable energy generators at the rates set by the government.

The government estimated that feed-in tariffs to support small-scale low-carbon generation would cost £8.6 billion up to 2030 and produce monetised carbon savings worth £0.42 billion.[7]

Year one feedback[edit]

A new study from the University of London has assessed the first year of the UK FIT scheme through interviews with both users of the scheme and government figures. The key findings are that users have had a wide variety of experiences, depending on the technology they are working with, and that the government has very limited ambitions on small-scale renewable energy generation.

Domestic solar has performed well in the first year, with 28,028 of the 28,614 total solar installations (totalling nearly 78MW). Wind power has the next highest installation level with 1,348 (20.4MW). Small hydro had 206 (12.1MW), although many were not new installations, but had been transferred from the Renewable Obligation scheme. Micro-CHP had 98 installations (0.09MW), and Anaerobic Digestion (AD) had just 2 (0.66MW). AD is under scrutiny at present (April 2011) to determine why development has been so poor.

The study suggests that technologies have a variety of factors affecting their performance in terms of installation levels. The factors include cost, size, availability, standardisation of the technology, planning issues, ease of installation, perceived sensory impact (sight, sound and smell) and administrative complexity. Domestic PV scores very positively on all these factors, while small hydro and AD do far less well.

The proposed changes to the tariff levels for PV have been met with anger by many in the solar industry, but the FIT policy, along with the Green Investment Bank and now carbon reduction targets, are widely understood to be threatened by the Treasury department. This is due to the schemes being considered as liabilities on the national balance sheet.[8]

Reviews to feed-in tariff rates in 2011[edit]

Less than a year into the scheme, in March 2011 the new coalition Government announced that support for large-scale photovoltaic installations (greater than 50 kW) would be cut.[9] From 1 August 2011 the rate for installations over 50 kW will range from 19p/kWh to 8.5p/kWh for the largest qualifying installations (5MW), with the Government claiming that this would prevent the scheme from becoming 'overwhelmed'.[10]

Revised tariffs for farm-scale anaerobic digestion initially of either 14p/kWh or 13p/kWh,[11] depending on the installation size, were introduced from September 2011.[10]

On 31 October 2011 a second review of the Feed in Tariffs for low carbon electricity generation was announced which is likely to take effect from 12 December 2011. The rates for small photovoltaic installations have been reduced from 43.3p/kWh to 21 pence/kWh. The reason for the second review is that FITs for PV were being taken up too quickly and that the DECC funding allocation for FITs was in danger of being exceeded. A further reason is that the cost of installing PV panels has reduced by around 50% and therefore the FITs had become less of an encouragement to install PV panels and more of an incitement to profit from excessive subsidies. See revised tariff tables for FITs.[11]

Reviews to feed-in tariff rates in 2012[edit]

In its second year, the government announced further cuts to the FIT scheme. On 3 March the tariff was cut to 21p/kWh. This cut was originally scheduled for 12 December 2011 but was delayed, following a successful joint appeal to the High Court by Friends of the Earth and two solar companies, Solar Century and HomeSun.[12] The 1 August review of the FIT brought an additional cut to 16p/kWh. The cut was partnered with a rise in export rate (the price at which the homeowner can sell excess electricity back to the supplier) from 3.1p to 4.5p for every kWh of electricity exported to the grid.[13] The latest cut came into effect on 1 November, the tariff dropping to 15.44p/kWh, and this rate is set to remain until 1 February 2013. In addition to this, generators with more than 25 Solar PV installations were granted a 10% increase in the amount they receive of the FIT, from 80% to 90%, this however will not be likely to affect domestic users.[14] The cut in FITs was due to the falling installation costs, and the fact that people were applying for the feed-in tariff scheme in numbers exceeding DECC forecasts and funding allocations. The aforementioned rates would only affect new installations - existing schemes would not be affected . The new tariffs would also now be paid over 20 years instead of 25 years (It will remain linked to the Retail Price Index) with a review every three months based on solar PV uptake levels in the three different brands domestic (size 0-10 kW), small commercial (10-50 kW) and large commercial (above 50 kW and standalone installations).[15] Despite suggestions that the European solar market is in decline a report [16] by the International Energy Agency has shown that for a second year in a row solar PV was the dominant form of new electricity installation during 2012, ahead of both wind and gas power.

Related schemes[edit]

In addition to the feed-in tariff, a similar incentive - the Renewable Heat Incentive for renewable heat was introduced in November 2011.

Free solar[edit]

The scheme has created a large number of start up companies providing free electricity [17] in return for installing solar panels on the home owners roof. If the homeowner can not afford the capital outlay, the free solar companies offer a capital free way of getting the benefits of solar and free electricity. However if the home owner can afford the capital outlay it is more cost effective to purchase the solar equipment[18] directly.

Unfair treatment[edit]

There has been much criticism of the tariffs as being unequal. Those people who installed equipment before the FIT started, are given a fixed tariff of 9p per unit (9.9p from April 2012[11] ). Both the Conservatives and the Liberal Democrats pledged to reverse this in the 2010 General Election, but then reneged on this decision afterwards. The pioneers are now on a lower rate than that before FITs started, despite generating the same electricity.

There has also been criticism of the high rates for FITs compared to those for the Renewable Heat Incentive: the renewable heat technologies are more economic than renewable electricity generation so the government could save carbon much less expensively by increasing the RHI on ground source heat pumps (at 4.5 pence/kWh) compared to up to 21 pence/kWh for photovoltaic or up to 36 pence/kWh for wind turbines.
