A feed-in tariff (FIT) is paid by energy suppliers in the United Kingdom if a property or organisation generates their own electricity using technology such as solar panels or wind turbines and feeds any surplus back to the grid. [1] The FIT scheme was imposed on suppliers by the UK government, and applied to installations completed between July 2009 and March 2019.
The FIT scheme entered into law through the Energy Act 2008 [2] and commenced in April 2010, [3] with backdated applications accepted for generation systems installed from July 2009 onwards. [4] Payments were contracted for either 20 or 25 years. The scheme closed to new applicants on 31 March 2019. [5]
The Feed-In Tariff applies to small-scale generation of electricity using eligible renewable technologies. To encourage development of these technologies, feed-in tariffs pay the generator a certain amount – even for energy which the generator themselves consumes. [6] Electricity fed into the grid receives an additional export tariff. Costs for the programme are borne by all British electricity consumers proportionally. Payments through the scheme are intended to replace the ROCs available through the Renewables Obligation for small-scale renewable energy generators. In detail:
In 2010, the UK 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. [10]
A study from the University of London assessed the first year of the UK FIT scheme through interviews with both users of the scheme and government figures. The key findings were that users have had a wide variety of experiences, depending on the technology they are working with, and that the government had very limited ambitions on small-scale renewable energy generation.
Domestic solar performed well in the first year, with 28,028 of the 28,614 total solar installations (totalling nearly 78MW). Wind power was 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 came under scrutiny in 2011 to determine why development was so poor.
The study suggested 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. [12]
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. [13] From 1 August 2011 the rate for installations over 50 kW was to 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'. [14]
Revised tariffs for farm-scale anaerobic digestion initially of either 14p/kWh or 13p/kWh, [15] depending on the installation size, were introduced from September 2011. [14]
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. [15]
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. [16] 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. [17] A further cut came into effect on 1 November, the tariff dropping to 15.44p/kWh, and this rate was set to remain until 1 February 2013.
In addition, generators with more than 25 solar PV installations were granted a 10% increase in the amount they receive from the FIT, from 80% to 90%, this however will not be likely to affect domestic users. [18] 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 (they will remain linked to the Retail Price Index) with a review every three months based on solar PV uptake levels in three bands: domestic (size 0-10 kW), small commercial (10-50 kW) and large commercial (above 50 kW and standalone installations). [19] Despite suggestions that the European solar market was in decline, a report [20] by the International Energy Agency showed 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.
The Department for Business, Energy and Industrial Strategy (BEIS) published a consultation on 19 July 2018, and stated their intention to close the FIT scheme to new applicants from 1 April 2019 [21] and not replace it with a new subsidy. [22]
On 10 June 2019, Ofgem announced [23] that BEIS had introduced the Smart Export Guarantee (SEG), in force from 1 January 2020. This is not a direct replacement of the feed-in tariff scheme, but rather a new initiative that rewards solar generators for electricity exported to the grid. Energy suppliers with more than 150,000 domestic customers must provide at least one export tariff. [24] The export tariff rate must be greater than zero. Export is measured by smart meters which the energy supplier installs free of charge.
In September 2021, Ofgem published the Smart Export Guarantee (SEG) Annual Report 2020–21, stating that 4,593 generators signed up to a SEG tariff in 2020–21, with a total installed capacity of 19,195 kW; exports totalled 2,568,810 kWh and generators received £114,480 in payments. [25]
A similar incentive for renewable heat – the Renewable Heat Incentive – was introduced in November 2011.
The FIT scheme has created a number of start-up companies providing free electricity [26] in return for installing solar panels on the homeowner's roof. If the homeowner cannot afford the capital outlay, the companies offer a capital-free way of getting the benefits of solar and free electricity.[ citation needed ]
After the December 2015 Feed-in Tariff reductions were announced, some free solar panel installers ceased trading, or had plans to stop installing, as the returns were no longer financially viable. The change in the feed-in tariff equated to a 64% decrease in the generation tariff for solar arrays below 4 kW, which is the largest decrease since the scheme began in 2010. [27] The changes meant that larger systems (over 10 kW) received a higher feed in tariff rate than smaller domestic-sized systems, which might have led to the remaining free solar panel companies exclusively providing commercial installations.[ citation needed ]
Net metering is an electricity billing mechanism that allows consumers who generate some or all of their own electricity to use that electricity anytime, instead of when it is generated. This is particularly important with renewable energy sources like wind and solar, which are non-dispatchable. Monthly net metering allows consumers to use solar power generated during the day at night, or wind from a windy day later in the month. Annual net metering rolls over a net kilowatt-hour (kWh) credit to the following month, allowing solar power that was generated in July to be used in December, or wind power from March in August.
The Renewables Obligation (RO) is designed to encourage generation of electricity from eligible renewable sources in the United Kingdom. It was introduced in England and Wales and in a different form in Scotland in April 2002 and in Northern Ireland in April 2005, replacing the Non-Fossil Fuel Obligation which operated from 1990.
Microgeneration is the small-scale production of heat or electric power from a "low carbon source," as an alternative or supplement to traditional centralized grid-connected power.
Solar power is a fast-growing industry in Australia. As of September 2023, Australia's over 3.60 million solar PV installations had a combined capacity of 32.9 GW photovoltaic (PV) solar power, of which at least 3,823 MW were installed in the preceding 12 months. In 2019, 59 solar PV projects with a combined capacity of 2,881 MW were either under construction, constructed or due to start construction having reached financial closure. Solar accounted for 12.4% of Australia's total electrical energy production in 2021.
India's solar power installed capacity was 73.32 GWAC as of 31 December 2023.
Solar power accounted for an estimated 10.7% electricity in Germany in 2022, up from 1.9% in 2010 and less than 0.1% in 2000.
Financial incentives for photovoltaics are incentives offered to electricity consumers to install and operate solar-electric generating systems, also known as photovoltaics (PV).
Solar power has a small role in electricity production in the United Kingdom.
The availability and uptake of green electricity in the United Kingdom has increased in the 21st century. There are a number of suppliers offering green electricity in the United Kingdom. In theory these types of tariffs help to lower carbon dioxide emissions by increasing consumer demand for green electricity and encouraging more renewable energy plant to be built. Since Ofgem's 2014 regulations there are now set criteria defining what can be classified as a green source product. As well as holding sufficient guarantee of origin certificates to cover the electricity sold to consumers, suppliers are also required to show additionality by contributing to wider environmental and low carbon funds.
Renewable energy in the United Kingdom contributes to production for electricity, heat, and transport.
A feed-in tariff is a policy mechanism designed to accelerate investment in renewable energy technologies by offering long-term contracts to renewable energy producers. This means promising renewable energy producers an above-market price and providing price certainty and long-term contracts that help finance renewable energy investments. Typically, FITs award different prices to different sources of renewable energy in order to encourage the development of one technology over another. For example, technologies such as wind power and solar PV are awarded a higher price per kWh than tidal power. FITs often include a "digression": a gradual decrease of the price or tariff in order to follow and encourage technological cost reductions.
Feed-in electricity tariffs (FiT) were introduced in Germany to encourage the use of new energy technologies such as wind power, biomass, hydropower, geothermal power and solar photovoltaics. Feed-in tariffs are a policy mechanism designed to accelerate investment in renewable energy technologies by providing them remuneration above the retail or wholesale rates of electricity. The mechanism provides long-term security to renewable energy producers, typically based on the cost of generation of each technology. Technologies such as wind power, for instance, are awarded a lower per-kWh price, while technologies such as solar PV and tidal power are offered a higher price, reflecting higher costs.
Feed-in tariffs in Australia are the feed-in tariffs (FITs) paid under various State schemes to non-commercial producers of electricity generated by solar photovoltaic (PV) systems using solar panels. They are a way of subsidising and encouraging uptake of renewable energy and in Australia have been enacted at the State level, in conjunction with a federal mandatory renewable energy target.
Historically, the main applications of solar energy technologies in Canada have been non-electric active solar system applications for space heating, water heating and drying crops and lumber. In 2001, there were more than 12,000 residential solar water heating systems and 300 commercial/ industrial solar hot water systems in use. These systems presently comprise a small fraction of Canada's energy use, but some government studies suggest they could make up as much as five percent of the country's energy needs by the year 2025.
Grid parity occurs when an alternative energy source can generate power at a levelized cost of electricity (LCOE) that is less than or equal to the price of power from the electricity grid. The term is most commonly used when discussing renewable energy sources, notably solar power and wind power. Grid parity depends upon whether you are calculating from the point of view of a utility or of a retail consumer.
Solar power in Japan has been expanding since the late 1990s. The country is a major manufacturer and exporter of photovoltaics (PV) and a large installer of domestic PV systems, with most of them grid connected.
The Green Energy Act (GEA), formally the Green Energy and Green Economy Act, 2009, introduced in the Ontario legislature on February 23, 2009 and later repealed on January 1, 2019, was intended to expand renewable energy production, encourage energy conservation and create green jobs. Among many clauses, the GEA was best known for creating a number of feed-in tariff rates for different types of energy sources. Notable among these is the microFIT program for small non-commercial systems under 10 kilowatts, and FIT, the larger commercial version which covers a number of project types with sizes into the megawatts.
The Renewable Energy Sources Act or EEG is a series of German laws that originally provided a feed-in tariff (FIT) scheme to encourage the generation of renewable electricity. The EEG 2014 specified the transition to an auction system for most technologies which has been finished with the current version EEG 2017.
New York has a renewable portfolio standard of 30% from renewable sources by 2015. In 2015 24% was renewable, 6% short of the goal. Wind is the predominant generating technology. In 2018, the New York State Energy Research and Development Authority awarded long-term contracts to 22 utility-scale solar farms, totaling a combined capacity of 646 MW.
Solar power in Switzerland has demonstrated consistent capacity growth since the early 2010s, influenced by government subsidy mechanisms such as the implementation of the feed-in tariff in 2009 and the enactment of the revised Energy Act in 2018. By the end of 2022, solar photovoltaic (PV) capacity had reached 4.7 GW, a notable increase from the 0.1 GW recorded in 2010. Concurrently, the contribution of solar power to electricity generation also rose, climbing from 0.1% in 2010 to 6.2% in 2022.
