A feed-in tariff (FIT, standard offer contract advanced renewable tariff or renewable energy payments) is a policy mechanism designed to accelerate investment in renewable energy technologies. It achieves this by offering long-term contracts 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.
In addition, feed-in tariffs often include "tariff degression", a mechanism according to which the price (or tariff) ratchets down over time. This is done in order to track:p.25 and encourage technological cost reductions.:p.100 The goal of feed-in tariffs is to offer cost-based compensation to renewable energy producers, providing the price certainty and long-term contracts that help finance renewable energy investments.
- guaranteed grid access
- long-term contracts for the electricity produced
- purchase prices based on the cost of generation
Under a feed-in tariff, eligible renewable electricity generators (which can include homeowners, business owners, farmers, as well as private investors) are paid a cost-based price for the renewable electricity they produce. This enables a diversity of technologies (wind, solar, biogas, etc.) to be developed, providing investors a reasonable return on their investments. This principle was first explained in Germany's 2000 RES Act:
"The compensation rates...have been determined by means of scientific studies, subject to the provision that the rates identified should make it possible for an installation – when managed efficiently – to be operated cost-effectively, based on the use of state-of-the-art technology and depending on the renewable energy sources naturally available in a given geographical environment."
As a result, the tariff (or rate) may differ to enable various technologies to be profitably developed. This can include different tariffs for projects in different locations (e.g. rooftop or ground-mounted for solar PV projects), of different sizes (residential or commercial scale), and sometimes, for different geographic regions. The tariffs are typically designed to ratchet downward over time to both track, and encourage, technological change.
The fact that the payment levels are performance-based puts the incentive on producers to maximize the overall output and efficiency of their project.
As of 2010, feed-in tariff policies have been enacted in over 50 countries, including Algeria, Australia, Austria, Belgium, Brazil, Canada, China, Cyprus, the Czech Republic, Denmark, Estonia, France, Germany, Greece, Hungary, Iran, Republic of Ireland, Israel, Italy, Kenya, the Republic of Korea, Lithuania, Luxembourg, the Netherlands, Portugal, South Africa, Spain, Switzerland, Tanzania, Thailand, and Turkey. In early 2012 in Spain, the Rajoy administration suspended the Feed-in tariff for new projects.
In 2008, a detailed analysis by the European Commission concluded that "well-adapted feed-in tariff regimes are generally the most efficient and effective support schemes for promoting renewable electricity". This conclusion has been supported by a number of recent analyses, including by the International Energy Agency, the European Federation for Renewable Energy, as well as by Deutsche Bank.
There are three methods of compensation.
- Feed-in tariff - compensation is above retail, and as the percentage of adopters increases, the FIT is reduced to the retail rate.
- Net metering - compensation is always at the retail rate, and allows producers to use electricity at a different time than when it was generated. There is no limit to the number of customers using net metering, but requires utilities to store electricity if production exceeds demand. Best practices call for perpetual roll over of kilowatt hour credits rather than converting to a monetary compensation. Excess generation (annually) is treated separately, and ranges from lost, to avoided cost, to retail rate.
- Power Purchase Agreement - pays for the generation of electricity and is normally below the retail rate, although in the case of solar can be higher, because solar tends to be produced closer to during peak demand.
The United States (1978) 
While not called a feed-in tariff, the first form of feed-in tariff was implemented in the US in 1978 under President Jimmy Carter, who signed the National Energy Act (NEA). This Act included five separate Acts, one of which was the Public Utility Regulatory Policies Act (PURPA). The purpose of the National Energy Act was to encourage energy conservation and the development of new energy resources, including renewables such as wind, solar and geothermal power.
Within PURPA was a provision that required utilities to purchase electricity generated from qualifying independent power producers at rates not to exceed their avoided cost. Avoided costs were designed to reflect the cost that a utility would incur to provide that same electrical generation. Different interpretations of PURPA prevailed in the 1980s: some utilities and state utility commissions interpreted avoided costs narrowly to mean avoided fuel costs, while others chose to define "avoided costs" as the "avoided long-run marginal cost" of generation. The long-run costs referred to the anticipated cost of electricity in the years ahead. This last approach was adopted by California in its Standard Offer Contract No. 4. Another provision included in the PURPA law was that utilities were prevented from owning more than 50% of projects, a clause that was introduced to encourage new participants to enter the electricity generation industry.
In order to comply with PURPA, certain states began offering Standard Offer Contracts to renewable power producers. California's Public Utility Commission established a number of Standard Offer Contracts, including Standard Offer No.4 (SO4), which made use of fixed prices, based on the expected long-run cost of generation. The long-run estimates of electricity costs were based on the belief (widely held at the time) that oil and gas prices would continue to increase. This led to an escalating schedule of fixed purchase prices, designed to reflect the long-run avoided costs of new electrical generation. By 1992, private power producers had installed approximately 1,700 MW of wind capacity in California, some of which is still in service today. The adoption of PURPA also led to significant amounts of renewable energy generation in states such as Florida, and Maine.
This notwithstanding, PURPA continues to have negative connotations in the U.S. electricity industry. When oil and gas prices plummeted in the late 1980s, the Standard Offer Contracts that were signed to encourage new renewable energy development seemed high by comparison. As a result, PURPA contracts came to be seen as an expensive burden on electricity ratepayers, a connotation that remains to this day.
Another source of opposition to PURPA stems from the fact that it was designed to encourage non-utility generation. This was interpreted as a threat by many large utilities at the time, particularly those operating in monopoly environments. As a result of its encouragement of non-utility generation, PURPA has been interpreted as an important step toward increasing competition in the U.S. electricity industry by some.
Developments in Europe (1990) 
In 1990, Germany adopted its "Stromeinspeisungsgesetz" (StrEG), or its "Law on Feeding Electricity into the Grid" The StrEG required utilities to purchase electricity generated from renewable energy sources at prices that were determined as a percentage of the prevailing retail price of electricity. The percentage offered to solar and wind power was set at 90% of the residential electricity price, while other technologies such as hydro power and biomass sources were offered percentages ranging from 65–80%. A project cap of 5 MW was included
While Germany's StrEG (Feed-in Law) was insufficient to encourage costlier sources of generation such as solar photovoltaics, it proved relatively effective at encouraging lower-cost technologies such as wind power, leading to the deployment of 4 400 MW of new wind capacity between 1991 and 1999, representing approximately one third of the global capacity at the time.
An additional challenge that was addressed by Germany's Feed-in Law was the right to interconnect to the utility's grid. The StrEG stipulated that renewable electricity producers would be guaranteed grid access. Similar percentage-based feed-in laws were adopted in Spain, as well as in Denmark in the 1990s.
Germany's Renewable Energy Sources Act 
Germany's Feed-in Law underwent a major restructuring in the year 2000, being re-framed as the Act on Granting Priority to Renewable Energy Sources ("Erneuerbare Energien Gesetz", German Renewable Energy Act). In its new form, it has proved to be the world's most effective policy framework at accelerating the deployment of renewable energy technologies.
Germany's new feed-in tariff made a number of important changes to its previous policy:
- first, the purchase prices were methodologically based on the cost of generation from renewable energy sources. This led to different prices for wind power, solar power, biomass and biogas sources, and geothermal energy, as well as different prices for projects of different sizes, to account for economies of scale;
- purchase guarantees were extended for a period of 20 years;
- utilities were now allowed to participate; and finally
- the rates offered were designed to decline annually based on expected cost reductions, in a mechanism known as "tariff degression".
Since it has been the most successful, the German policy (amended in 2004 and 2008) often provides the benchmark against which other feed-in tariff policies are considered.
Following the German approach, a number of countries have begun adopting feed-in tariff policies. These long-term contracts for electricity are typically offered in a non-discriminatory manner to all producers of electricity generated from renewable energy sources. Because the purchase prices are based on the cost of generation, investors are assured that efficiently operated projects will yield a reasonable rate of return.
This principle was explained in Germany's 2000 RES Act:
"The compensation rates...have been determined by means of scientific studies, subject to the proviso that the rates identified should make it possible for an installation – when managed efficiently – to be operated cost-effectively, based on the use of state-of-the-art technology and depending on the renewable energy sources naturally available in a given geographical environment."
Feed-in tariff policies typically target a rate of return ranging from 5–10%.
Feed-In Tariffs (REFIT) have been associated with a large growth in solar power in Spain, Germany and wind power in Denmark.
The success of solar PV in Germany, driven by the feed-in tariff policy, has resulted in a drop peak electricity prices by up to 40%, with savings between 520 million and 840 million € for consumers. Savings for consumers have meant conversely reductions in the margin of profit of big electric power companies, which reacted by lobbying the German government against the feed-in tariff policy, which have seen a major cut in 2012. Energy utilities have since lobbied for the abolition, or against the introduction, of feed-in tariffs in other parts of the world, like Australia and California. Increase in the solar share in the production of energy in Germany has also having the effect of closing gas fired and coal-fired generation plants.
Effects on electricity rates 
FITs have been shown different effects in the price of electricity per customer. In some cases they have led to a small annual increase, while in other cases to reductions.
Theoretically a feed-in tariff involves a temporary increase in electric rates for a long term benefit. Increases have been attributed as a result of the fact that electricity generated from renewable energy sources is typically more expensive than electricity generated from conventional sources. Costs of approximately four Euros per month per household are recorded in Germany. Despite this cost, a number of analyses have shown that these price increases, however, can be offset by the price-dampening effect that large amounts of lower cost renewable energy sources (such as wind and solar power) can have on spot market prices. This is attributed in large part to what is called the merit order effect. This has led to electricity price reductions in Spain, Denmark, and Germany.
Grid parity 
Some have argued that feed-in tariffs can be used to accelerate the pace at which renewable energy technologies become cost-competitive with electricity provided from the grid. The rapid deployment of renewable energy under feed-in tariffs seen in countries like Germany, Denmark and Spain has undoubtedly contributed to reducing technology costs, and hence, in accelerating this trend. For instance, wind and solar technology costs have decreased dramatically since the 1960s and 1970s, as the technologies have become more widespread, manufacturing processes have improved, innovations have been incorporated, and gains have been harnessed from economies of scale.
While it is true that large scale deployment of renewable energy technologies contributes to advancing toward grid parity, grid parity itself is a moving target, both in time (i.e. during the course of the day and over the course of years) and in space (i.e. geographically). The price of electricity from the grid varies widely from high-cost jurisdictions such as Hawaii and California, to lower-cost jurisdictions such as Wyoming, and Idaho. Similarly, due to their dependence on diesel generators, islands typically have higher electricity costs than on the mainland. In jurisdictions with time-of-use pricing the electricity price changes over the course of the day, rising during high-demand hours (e.g. 11AM – 8 PM) and declining during low-demand hours.
In certain jurisdictions, wind power, landfill gas, and certain forms of biomass generation are already lower-cost (on a per-kWh basis) than electricity provided from the grid. In fact, "grid parity" has already been obtained in certain jurisdictions that continue to use feed-in tariffs (e.g. the generation cost from landfill gas systems in Germany are currently lower than the average electricity spot market price) And in remote areas, electricity from solar photovoltaics can be cheaper than building new distribution lines to connect up to the main transmission grid.
There are other reasons to retain FIT laws even as grid parity approaches, because there are other important aspects of FIT laws which should be retained even if remuneration drops to 1:1 equivalence with the retail electricity price. These include the obligation to purchase, the obligation to connect and the long term payment guarantee associated with FIT laws.
Policy alternatives and complements 
Schemes such as quota-based mechanisms (Renewable Portfolio Standards) and subsidies create limited protected markets for renewable energy. The supply of renewable energy is achieved by obliging suppliers to deliver to consumers a portion of their electricity from renewable energy sources. To do this, they collect green electricity certificates. Hence, a market is created in green electricity certificates which, according to the theory, generates downward pressure on the prices paid to renewable energy developers. This is based on the theory of perfect competition where there is a multiplicity of buyers and sellers in a market where no single buyer or seller has a big enough market share to have a significant influence on prices. Although, in practice, markets are very rarely perfectly competitive, the assumption is still that a relatively competitive market will produce a more efficient use of resources compared to a system where prices are set by analysts.
The fundamental problem with the quota scheme is that there is no long-term certainty. When a quota is set either for a period of time or for a quantity of power, once that goal is reached then there is nothing to keep the green power producers from becoming uneconomic in the face of power produced from coal-fired power stations and hence collapsing as businesses. This inevitability with the quota method means that there is reluctance on behalf of investors to get involved in the first place. Those that do get involved are short-term speculators rather than long-term entrepreneurs and so instability is inherent in this system.
Feed-in tariffs by country 
Feed-in tariff laws were in place in 46 jurisdictions across the world by 2007. Research for information on feed in tariffs is difficult to find and typically extensive research is required to find it. Information about solar feed in tariffs may be found in a consolidated form, however not all of the countries are listed in this source.
To cover the additional costs of producing electricity from renewables and for the costs of diversification, producers of electricity from renewables will get a bonus for each kWh produced, marketed or consumed. For electricity generated from solar or radiant heat only, the bonus is 300% of the price per kWh of electricity produced by the market operator defined by Law 02-01 of 22 Dhu El Kaada 1422 corresponding to 5 February 2002 above, and this when the minimum contribution of solar energy represents 25% of all primary energy. For electricity generated from facilities using solar thermal systems solar-gas hybrid, the bonus is 200% of the price per kWh.
For contributions of solar energy below 25%, said the bonus is paid in the following conditions:
|20% to 25%||180%|
|15% to 20%||160%|
|10% to 15%||140%|
|5% to 10%||100%|
|0 to 5%||0|
The price of electricity is fixed by the CREG (Gas and Electricity Regulatory Commission). According to the last decision which fixed it, the consumer pays his electricity as below:
- 1.77 DZD/kWh for a consumption which is lower than 41.6 kWh/month.
- 4.17 DZD/kWh for a consumption which is higher than 41.6 kWh/month.
The other consumers (Industry, agriculture...etc.), they pay their electricity 4.17 DZD/kWh.
Furthermore the feed-in tariff provides with bonuses for electricity generated by cogeneration. The bonus will be 160% taking into account a thermal energy use by 20% of all primary energy used. The bonuses for solar generated electricity and cogeneration are cumulative. Remuneration of the generated electricity will be guaranteed over the whole plant lifetime.
Feed-in tariffs had been introduced by the States in 2008 in South Australia and Queensland, 2009 in the Australian Capital Territory and Victoria and 2010 in New South Wales, Tasmania and Western Australia. In the Northern Territory there are only local feed-in tariff schemes. A uniform federal scheme to supersede all State schemes has been proposed by Tasmanian Greens Senator Christine Milne, but not enacted. By mid-2011, FIT in NSW and ACT had been closed to new generators, as the installed capacity cap had been reached. In NSW, both the FiT and the cap were cut, due to the overly generous original settings. The new conservative Victorian government has replaced the original FiT with a less generous transitional FiT of 25c per kilowatt hour for any power generated excess to the generator's usage, pending the outcome of an inquiry by the Victorian Competition and Efficiency Commission. This does not meet the normal definition of feed-in tariff, and is referred to as a "fake feed-in tariff". It is actually net metering with a payment for any kilowatt credit, instead of the normal roll over.
Ontario introduced a feed-in tariff in 2006, and revised it in 2009 and 2010, increasing from 42¢/kWh to 80.2¢/kWh for micro-scale (≤10 kW) grid-tied photovoltaic projects, and decreasing to 64.2¢/kWh for applications received after 2 July 2010. Applications received prior to then had until 31 May 2011 to install the system to receive the higher rate. Ontario's FIT program also includes a tariff schedule for larger projects up to and including 10MW solar farms at a reduced rate. As of April 2010, several hundred projects have been approved, including 184 large scale projects, worth $8 billion all together. By April 2012, 12,000 systems had been installed, and the rate was decreased again, to 54.9¢/kWh, for applications received after 1 September 2011. (See Ontario Power Authority Feed-in Tariff program for renewable energy)
As of August 2011 a national feed-in tariff for solar projects was issued, and is about US$0.15 per kWh.
"China has set a fixed feed-in tariff for new onshore wind power plants in a move that will help struggling project operators to realise profits. The National Development and Reform Commission (NDRC), the country's economic planning agency, announced at the weekend four categories of onshore wind projects, which according to region will be able to apply for the tariffs. Areas with better wind resources will have lower feed-in tariffs, while those with lower outputs will be able to access more generous tariffs.
The tariffs per kilowatt hour are set at 0.51 yuan (US 0.075, GBP 0.05), 0.54 yuan, 0.58 yuan and 0.61 yuan. These represent a significant premium on the average rate of 0.34 yuan per kilowatt hour paid to coal-fired electricity generators.".
Czech Republic 
Czech Republic introduced a feed-in tariff by act of law no. 180/2005 for wide range of renewable sources in 2005. Tariff is guaranted for 15–30 years (depends on source). Supported sources are small hydropower (up to 10 MW), biomass, biogas, wind and photovoltaics. As of 2010 highest tariff is 12.25 CZK/kWh for small photovoltaic. In 2010 over 1200 MW of photovoltaics were installed, but at the end of the year the FiT was eliminated for larger systems, and reduced by 50% for smaller systems, and in 2011, no photovoltaic systems were installed.
The administrative procedure for the ground-mounted PV systems market segment was significantly modified in late 2009. The distinction between the segments is essentially based on the capacity of the PV installation, which determines the complexity of the administrative process. Differences between administrative procedures on regional level have not been detected. Since the decree of 4 March 2011, the feed-in tariff (FiT) is only attractive for installations less than 100 kWp in size. Above 100 kWp, the FiT is established at 0,117 €/kWh (until 30 September 2011), thus severely limiting the profitability of the installation. A call for tenders for PV projects above 250 kWp has been launched on 15 September 2011. Through this call, PV projects are analysed on multiple criteria, including the FiT requested by the applicant. The results of this call for tenders will be known only at the end of March 2012.
Medium sized PV installations on rooftops up to 100 kWp in size are essentially supported by the feed-in tariff (FIT). The main obstacles for the development of the PV system are the grid connection procedure and the vagueness of certain regulations. Differences between administrative procedures at regional level have not been detected. Since the decree of 4 March 2011, FIT is attractive only for installations up to 100 kWp in size. Above 100 kWp, it is limited to 11,688cts€/kWh (until the next review on 30 September 2011) this severely limiting the profitability of the PV installation. A call for tenders for rooftop PV projects above 100 kWp has been launched on 1 August 2011. This call will evaluate PV projects on the basis of the FIT requested by the applicant.
On 19 April 2012 the FIT for small systems was reduced to €0.1079 for ground mounted systems, and to €0.1934 for residential rooftop arrays.
First introduced in 2000, the Erneuerbare-Energien-Gesetz (EEG) law is reviewed on a regular basis and the 2012 version is currently in force. Its predecessor was the 1991 "Stromeinspeisegesetz". As of May 2008, the cost of the program added about €1.01 (USD1.69) to each monthly residential electric bill. In 2012 the additional costs have risen to €0.03592/kWh.
Feed-in tariff rates for PV electricity vary depending on the size and locations of the systems and are shown below. Since 2009, there are additional tariffs for electricity immediately consumed rather than supplied to the grid with increasing returns if more than 30% of overall production is consumed on-site. This is to incentivise a demand side management and help develop solutions to the intermittency of solar power. Duration of tariff is usually 20 calendar years plus the year of installation. Systems receive the tariff in effect at the time of installation for the entire duration.

India's inaugurated its most ambitious solar power program to date on 9 January 2010. The Jawaharlal Nehru National Solar Mission (JNNSM) was officially announced by Prime Minister of India on 12 January 2010. This program aims to install 20,000 MW of solar power by 2022. The first phase of this program aims to install 1000 MW by paying a tariff fixed by the Central Electricity Regulatory Commission (CERC) of India. While in spirit this is a feed in tariff, there are several conditions on project size and commissioning date. Tariff for solar PV projects is fixed at Rs. 17.90 (USD 0.397/kWh). Tariff for solar thermal projects is fixed Rs. 15.40 (USD 0.342/kWh). Tariff will be reviewed periodically by the CERC.
Indonesia has adopted a scheme of FiTs. The Indonesian government, operating mainly through the State Electricity Corporation (Perusahaan Listrik Negara, or PLN), is aiming to encourage independent power producers (IPPs) to invest in the electric power sector. Numerous IPPs are investing in some large plants (over 500 MW) and many smaller plants (such as 200 MW and smaller). To support this IPP investment, FiT arrangements are agreed with the PLN. Prices for the FiTs vary widely from relatively low prices for large coal-based plants such as the Cirebon coal plant which began operations in late 2012 to higher prices for smaller geothermal plants producing more expensive power from distant locations such as the Wayang Windu geothermal plant in West Java.
سانا (SANA), first introduced FiT in 2008 for purchasing renewable energy from investors. A price of 1300 Rials/kWh was set for renewable electricity. For 4 hours in the mid-night, the price is 900 Rials.
From 2006 to 2011 the sitting Ministers for Communications Energy and Natural Resources (Noel Dempsey, Eamon Ryan) have at various times announced Feed in Tariffs for renewable electricity in Ireland. However, they have never actually put feed in tariffs in place. This has seriously hindered the growth of renewable electricity in Ireland. Currently (Q2:2011) REFIT (a Renewable Energy Feed-In Tariff) is being negotiated between DCENR and the EU, the industry is hopeful that REFIT will be available, however much investment funds have been lost to oversees projects at this stage. Industry associations (such as the Irish BioEnergy Association) are strongly lobbying government and government departments to have feed in tariffs available to the renewable energy sector.
On 2 June 2008, the Israeli Public Utility Authority approved a feed-in tariff for solar plants. The tariff is limited to a total installation of 50MW during 7 years, whichever is reached first, with a maximum of 15 kWp installation for residential and a maximum of 50kWp for commercial. Bank Hapoalim offered 10 year loans for the installation of solar panels. The National Infrastructures Ministry announced that it would expand the feed-in tariff scheme to include medium-sized solar-power stations ranging from 50 kilowatts to 5 megawatts. The new tariff scheme caused solar company Sunday Solar Energy to announce that it would invest $133 million to install photovoltaic solar arrays on kibbutzim, which are social communities that divide revenues amongst their members.
Italy introduced a feed-in tariff in February 2007. By 2011 Italy installed almost more photovoltaics than any other country (7128 MW, total 9450 MW ), after Germany (7500 MW, total 24820 MW), and reduced the FIT.
A new FIT of ¥42 (US$0.525) per kWh for 10 years for systems less than 10 kW, and ¥40 (US$0.50) for larger systems, but for 20 years, began on 1 July 2012. The rate will be reviewed annually, for subsequently connected systems.
The Netherlands 
The Netherlands has no FIT yet. However, the Dutch Cabinet agreed on 27 March 2009 to implement some parts of a feed-in tariff during a renegotiation of the government agenda in response to the global financial crisis. The proposed regulation may adjust the quota incentive system. As of the summer of 2009, The Netherlands has a subsidy system. The subsidy budget has a quota for diverse types of energy, at several tens of million euro. The budget for wind is hardly used, because the tariffs are too low. The 2009 budget for Wind on Land was 900 MW (incl unused 400 MW from 2008); only 2.5 MW was used. Dutch utilities have no obligation to buy energy from windparks. The tariffs change yearly, to compensate the change in market prices. This creates uncertain investment conditions. The current subsidy system was introduced in 2008. The previous subsidy scheme stopped in 2005 because it became "too expensive". In 2009, Dutch windparks are still being built with grants from the old scheme. The old and new subsidy scheme is fed from the general budget.
The most probable change towards the FIT is that the subsidy budget will be fed with a small increase of the kWh price. The quota remain. End of November 2009 the Dutch Government spoke out that they now finally will also follow the Germans with their FiT to make investments in Sustainable Energy for investors much more interesting. A feed-in tariff was briefly adopted in 2011, but ended a month later, in February. A new feed-in tariff is being considered in 2012.
South Africa 
"South Africa's National Energy Regulator (NERSA) announced 31 March 2009 the introduction of a system of feed-in tariffs designed to produce 10 TWh of electricity per year by 2013. The feed-in tariffs announced were substantially higher than those in NERSA's original proposal. The tariffs, differentiated by technology, will be paid for a period of 20 years.
NERSA said in its release that the tariffs were based, as in most European countries, on the cost of generation plus a reasonable profit. The tariffs for wind energy and concentrating solar power are among the most attractive worldwide.
The tariff for wind energy, 1.25 ZAR/kWh (€0.104/kWh) is greater than that offered in Germany and more than that proposed in Ontario, Canada.
The tariff for concentrating solar, 2.10 ZAR/kWh, is less than that in Spain, but offers great promise in the bright sunlight of South Africa. NERSA's revised program followed extensive public consultation.
Stefan Gsänger, Secretary General of the World Wind Energy Association said in a release that "South Africa is the first African country to introduce a feed-in tariff for wind energy. Many small and big investors will now be able to contribute to the take-off of the wind industry in the country. Such decentralised investment will enable South Africa to overcome its current energy crisis. It will also help many South African communities to invest in wind farms and generate electricity, new jobs and new income. We are especially pleased as this decision comes shortly after the first North American feed-in law has been proposed by the Government of the Canadian Province of Ontario".
However, the feed-in tariff was abandoned before being promulgated in favor of a competitive bidding process launched on 3 August 2011. Under this bidding process, the South African government plans to procure 3,750MW of renewable energy: 1,850MW of onshore wind, 1,450MW of solar PV, 200MW of CSP, 75MW of small hydro, 25MW of landfill gas, 12.5MW of biogas, 12.5MW of biomass, and 100MW of small projects. The bidding process comprises two steps:
- Qualification phase. Projects are assessed based on structure of the project, legal, land acquisition and use, financial, environmental consent, technical, economic development and bid guarantee
- Evaluation phase. Compliant bids are then evaluated based on: (1) price relative to a ceiling provided in bid documentation, accounting for 70% of the decision, and (2) economic development, accounting for 30% of the decision.
The first round of bids was due on 4 November 2011. The SA government is expected to announce preferred bidders before COP17 in December. PPA's are expected to be in place by June 2012. Projects should be commissioned by June 2014, except CSP projects which are expected by June 2015.
Spanish feed-in legislation was set by Royal decree 1578/2008 (Real Decreto 1578/2008), for photovoltaic installations, and Royal decree 661/2007 for other renewable technologies injecting electricity to the public grid. Originally under the 661/2007, photovoltaic feed-in tariffs have been developed under a separate specific law frame due to the rapid growth experienced by this technology since release of the original scheme.
The decree 1578/2008 categorizes installations in two main groups with differentiated tariffs:
- Building Integrated installations; with 34c€/kWh in systems up to 20 kW of nominal power, and for systems above 20 kW with a limit of nominal power of 2MW tariff of 31c€/kWh
- Non integrated installations; 32c€/kWh for systems up to 10MW of nominal power.
For other technologies decree 661/2007 sets up:
|Energy Source||Feed-in Tariff|
|Cogeneration systems||maximum FiT of 13.29c€/kWh during lifetime of system.|
|Solar thermoelectric||26.94 c€/kWh for the first 25 years|
|Wind systems||up to 7.32 c€/kWh for the first 20 years|
|Geothermal, wave, tidal and sea-thermal||6.89 c€/kWh for the first 20 years|
|Hydroelectric||7.8 c€/kWh for the first 25 years|
|Biomass and biogas||up to 13.06 c€/kWh for the first 15 years|
|Waste combustion||up to 12.57 c€/kWh for the first 15 years|
On 27 January 2012 the Spanish government temporarily stopped accepting new FiT applications for projects beginning operation after January 2013. Construction and operation of existing projects has not been affected. The country's electrical system has a €24 billion deficit. FiT payments have not contributed significantly to that deficit. In 2008 the FiT was expected to result in 400 MW of solar being installed. However, due to its being one of the highest in the world at the time, over 2600 MW was installed. Utilities in Spain do not have any way to pass on cost increases to consumers by increasing rates, and instead have simply been accruing a deficit.
Switzerland introduced the so-called "Cost-covering remuneration for feed-in to the electricity grid (CRF)" on 1 May 2008. In German, it is called Kostendeckende Einspeise-Vergütung, KEV.
The CRF/KEV applies to hydropower (up to 10 megawatts), photovoltaics, wind energy, geothermal energy, biomass and waste material from biomass and will be applicable for a period of between 20 and 25 years, depending on the technology. The implementation is done through the national grid operator SWISSGRID.
While high by appearance, the KEV tarif has been almost inconsequential, as the total amount of "extra" cost to the system has been severely limited and capped by law. Since about 2009, no more projects could be financed through the Swiss federal KEV scheme. About 15'000 projects are waiting for allocation of monies from the KEV scheme. If all those projects would be passed, Switzerland could immediately turn-off all its nuclear power plants, which currently supply 40% of the power.
Nevertheless, in 2011 after Fukushima, some local power companies, mostly owned by villages and cantons/provinces, have selectively started offering either the full KEV tarif as decided and calculated by the Swiss federal department of Energy BfE, or some part of that tarif, thereby creating a mini-boom in renewable energy.
As of March 2012 the KEV-FIT for Solar PV has been lowered several times to CHF 0.30-0.40/kWh (USD 0.33-0.44/kWh) depending on size, but is still higher than in Germany and most of the rest of the world. On the website of SwissGrid www.swissgrid.ch there is a tarif-calculation application to help with identifying the valid tarif for a new project. Much more important, however, is to find a local utility which will actually pay that tarif.
Politically there are many initiatives to broaden the approach of KEV. There is also a political discussion suggesting that a subsidy through a FIT mechanism is really only needed as long as the "external costs" of traditional power production are not included in the price of traditional nuclear and fossil electric power. E.g. the cost of nuclear waste disposal over a million years, or the cost of insuring against having a nuclear plant destroying most of Switzerland, or the true cost of CO2 which is placed at about EUR 200.- / tCO2, instead of the 2011-EU-ETS-pseudo-market-price of around EUR 5-10 / tCO2 have never been added to power prices. Once that was to take place and power prices would be requested to reflect full costs including all external costs, most renewable energy solutions would become instantaneous cost-leaders, eliminating the need for a FIT mechanism. Unfortunately, big-industry-lobbies in Switzerland are typically blocking the adopption of a true-cost mechanism for power. As a result, Switzerland's clean energy industry has fallen behind Germany, Italy, China and Spain in terms of clean energy competitiveness.
In 2006, the Thai government enacted a feed-in tariff that provides an adder paid on top of utility avoided costs, differentiated by technology type and generator size, and guaranteed for 7–10 years. Solar receives the highest, 8 baht/kWh (about US cents 27/kWh). Large biomass projects receive the lowest at 0.3 baht/kWh (at about 1 US cent per kWh). Additional per-kWh subsidies are provided for projects that offset diesel use in remote areas. Under the FIT program, as of 2010 March 1364 MW of private sector RE was online with an additional 4104 MW in the pipeline with signed PPAs. Biomass makes up the bulk of this capacity: 1292 MW (online) and 2119 MW (PPA only). Solar electricity is second but rapidly catching up, with 78 MW online and signed PPAs for an additional 1759 MW.
Uganda has launched a feed-in tariff in 2011. The Uganda Electricity Transmission Company Limited holds the transmission license in the country and was mandated by the Electricity Regulatory Authority to provide the following FIT for small-scale projects ranging from 0.5MW to 20MW. The complete guidelines can be found at http://www.era.or.ug/Pdf/Approved_Uganda%20REFIT%20Guidelines%20V4%20(2).pdf
|Technology||Tariff (US$/kWh)||O&M %age||2011||2012||2013||2014||Payment Period (Years)|

Ukraine has introduced the law 'On feed-in tariff' as of 25 September 2008. The law guarantees grid access for renewable energy producers (small hydro up to 10 MW, wind, biomass, photovoltaic and geothermal). The feed-in tariffs for renewable power producers are set by the national regulator. As of February 2013 the following tariffs per kWh were applied: biomass – UAH 1.3446 (EUR 0.13), wind – UAH 1.2277 (EUR 0.12), small hydro – UAH 0.8418 (EUR 0.08), solar - UAH 5.0509 (EUR 0.48). In case of significant fluctuations of the national currency against Euro the feed-in tariff is adjusted to reflect the changes.
United Kingdom 
Feed-in tariffs in the United Kingdom were first announced in October 2008 by the UK Secretary of State for Energy and Climate Change, Ed Miliband, who announced that Britain would implement a scheme by 2010, in addition to its current renewable energy quota scheme (ROCS). In July 2009, he presented details of the scheme, which began in early April 2010.
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. This was in response to European speculators lining up to establish huge solar farms in the West Country, which would have absorbed disproportionate amounts of the fund.
On 9 June 2011, DECC confirmed that Feed-in Tariffs cut for solar PV systems above 50 KW after 1 August 2011. Many are disappointed with the decision of DECC, especially after long time discussion with public. Still some think positive about the new Feed-in Tariffs, from the report published by PVinsights. It is believed that the total subsidies for solar PV industry is not changed, UK government tries to trim the tariffs for large systems in order to benefit smaller systems. The fast track review is based on the long term plan to reach an annual installation of 1.9GW in 2020. In October 2011 DECC announced dramatic cuts of around 55% to feed in tariff rates, with additional reductions for community or group schemes. The cuts were to be effective from 12 December 2011, with a consultation exercise to end on 23 December 2011. This was successfully challenged in the high court by an application for judicial review, jointly made by environmental pressure group Friends of the Earth (FoE) and two solar companies - Solarcentury and HomeSun. The judgment, made by Mr Justice Mitting after a two-day court hearing, was hailed as a major victory by green campaigners and the solar industry. Lawyers for the Department of Energy and Climate Change immediately moved to apply for permission to appeal the judge's ruling. The appeal was unanimously rejected by the Supreme Court, allowing anyone who installed their systems before 3 March 2012 to receive the higher FiT of 43.3 p/kWh.
The 30.7 p/kWh rate was available for solar systems up to 5 MW, and consequently no larger systems were built.
|Energy Source||Feed-in Tariff|
|1 April 2012 to 31 July 2012||1 August 2012 – 30 September 2012|
|AD biogas||9.9 to 14.7p/kWh||9.9 to 14.7p/kWh|
|Hydro||4.9 to 21.9 p/kWh||4.9 to 21.9 p/kWh|
|Solar PV||8.9 to 21.0p/kWh||7.1 to 15.44 p/kWh|
|Wind||4.9 to 35.8 p/kWh||4.9 to 35.8 p/kWh|
|Previously installed systems||9.9 p/kWh||9.9 p/kWh|
As of April 2012, 263,274 systems, totaling 1,152.835 MW, were receiving FiT payments. Of these, 260,041 were solar photovoltaic, totaling 1,057.344 MW. Payments are for 25 years. A typical photovoltaic system costing £7,500 pays for itself in 7 years 8 months, and generates £23,610 over 25 years.
United States 
"While feed-in tariffs are most closely associated with solar photovoltaic panels, utilities managing the programs in Vermont and California will also pay a set price for electricity generated from other renewable sources, like wind.
California's Sacramento Municipal Utility District (SMUD) program is open to homeowners who are not participating in another program, called net metering, which allows anyone whose system is producing more electricity than they need to sell the excess back to the utility, thus reducing their electric bill. But once their bill falls to zero, the homeowner gets no more money from the system.
Jon Bertolino, a spokesman for SMUD, said that customers with land to spare had been asking whether, if they put up small solar farms, the utility would buy the excess electricity.
As long as they are not part of the net-metering program and not seeking the $1.90- to $2.20-per-watt ratepayer subsidy for their new panels under the state's "Million Solar Roofs" program, Mr. Bertolino said, small generators can sell their power to SMUD. The rates would depend on the time of day the power is generated, ranging from a low of 5 or 6 cents a kilowatt-hour to 30 cents on a hot summer afternoon; the size of eligible systems is capped at 5 megawatts (and the program overall has a 100-megawatt cap).
The Vermont law caps the size of individual systems at 2.2 megawatts. Solar energy fetches a fixed price of 30 cents a kilowatt-hour, and other forms of renewables fetch lower rates".
In 2010, Marin Energy Authority launched the first Community Choice Aggregate Feed-in Tariff program. The program was updated in November 2012, and now offers 20-year fixed-price contracts, with prices varying by energy source (peak, base-load, intermittent) and progress towards the current program cap of 10-MW.
Municipal utility companies have enacted feed in tariff pilot programs in Palo Alto and Los Angeles: Palo Alto CLEAN (Clean Local Energy Accessible Now) is a program to purchase up to 4MW of electricity generated by solar electric systems located in CPAU's service territory. In this first year (2012), there will be a minimum project size of 100 kW. Rates of purchase are between 12.360 ¢/kWh to 14.003 ¢/kWh depending on the length of the contract. The City began accepting applications on 2 April 2012.
On 17 April 2012, Los Angeles Department of Water and Power's Board of Water and Power Commissioners approved a 10MW Feed-in-Tariff Demonstration Program. The program's goal is to encourage renewable energy development within the Los Angeles Basin and help meet the 33% Renewable Portfolio Standard Mandate by 2020.
As of 1 January 2010 state laws have passed allowing homeowners who produce more than they use over the course of the year to opt in to be able to sell the excess power to the utility at a currently undisclosed rate (the rate decision has a 1 January 2011 deadline). Previously the homeowner would get no credit for over-production over the course of the year. In order to get the California Solar Initiative (CSI) rebate the customer is not allowed to install a system that inherently over-produces thereby encouraging efficiency measures to be installed after solar installation. This over-production credit is not available to certain municipal utility customers namely Los Angeles Water and Power.
In February 2009, city commissioners in Gainesville, Florida, approved the nation's first solar feed-in tariff. The program is open to small, medium and large projects, but is capped at 4 MW per year. As of 2011, Gainesville has increased solar generated electricity from 328 kW to 7,391 kW. Solar energy now makes up approximately 1.2% of peak load energy (610 MW) in Gainesville.
In September 2009 the Hawaii Public Utilities Commission required Hawaiian Electric Company (HECO & MECO & HELCO) to pay above-market prices for renewable energy fed into the electric grid. The policy offers project a set price and standard 20-year contract. The PUC plans to review the initial feed-in tariff two years after the program starts and every three years thereafter.
|Renewable Generator Type and Size||FIT Rate (cents/kWh)|
|Baseline FIT rate for any RPS-eligible technology under the max. size limit||13.8|
|Tier 1 On-Shore Wind < 20 kW||16.1|
|Tier 1 In-line Hydropower < 20 kW||21.3|
|Tier 2 On-Shore Wind 20-100/500 kW||13.8|
|Tier 2 In-line Hydropower 20-100/500 kW||18.9|
|Renewable Generator Type and Size||FIT Rate (cents/kWh)|
|35% state tax credit||24.5% refundable tax credit|
|Tier 1 PV < 20 kW||21.8||27.4|
|Tier 1 CSP < 20 kW||26.8||33.1|
|Tier 2 PV 20-100/500 kW||18.9||23.8|
|Tier 2 CSP 20-100/500 kW||25.4||27.5|
The PUC's decision sets project size limits of five megawatts (MW) for the island of ʻOahu and 2.72 MW for Maui and Hawaii island. The Commission's decision caps the total amount of feed-in tariff projects brought onto the electricity grid at 5% of the system peak on Oahu, Maui, and the Big Island for the first two years of the program. Tier 3 is still pending a Decision and Order based on the findings of the Reliability Standards Working Group (a "docket within the docket").
Tier 2 and 3 project size caps vary by island and by technology. Tier 2 includes larger systems that are less than or equal to: 100 kW-AC for on-shore wind and in-line hydropower on all islands; 100 kW-AC for PV and CSP on Lanai and Molokai; 250 kW-AC for PV on Maui and Hawaii; 500 kW-AC for CSP on Maui and Hawaii; and 500 kW-AC for PV and CSP on Oahu. Tier 3 covers systems larger than the Tier 2 caps.
In the 2009 Maine Legislature's session, a "Feed-In" Tariff bill, (LD 1450), introduced by Rep. Herbert Adams (D-Portland), was considered. It made it from the House to the Senate, where is was killed 21 May. Known as "An Act to Establish the Renewable Energy Resources Program" it was closely modeled on the German law. In June 2009 a pilot program was initiated however, and is available for projects up to 10MW in size. On April 24, 2013, the Maine Utility and Energy Committee will consider a new bill: LD1085 "An Act To Establish the Renewable Energy Feed-in Tariff".
New York 
The Long Island Power Authority (LIPA) adopted a feed-in tariff on 16 July 2012, for systems from 50 kW (AC) to 20 MW (AC), and is limited to 50 MW (AC). Additional blocks could be added later. As customers can not use their own electricity, it is actually a 20 year fixed rate power purchase agreement, and LIPA retains the SRECs. The 2012 NY legislature failed to pass legislation which would have adopted a New York market for SRECs starting in 2013. Payment is 22.5¢/kWh, which is actually less than what LIPA is currently paying for peak generation at times. At an estimated avoided cost of $0.075/kWh, the program adds about $0.44/month to the average household electric bill.
In June 2009, Oregon established a pilot solar volumetric incentive rate and payment program* with legislation. Under this incentive program, systems are paid for the kilowatt-hours (kWh) generated over a 15-year period, at a rate set at the time a system is initially enrolled in the program. The Oregon Public Utility Commission (PUC) was left with the discretion to establish rates and rules by 1 July 2010. The PUC established rates and rules in May 2010. This program must be offered by the three investor-owned utilities in Oregon and will be administered by the utilities, though the PUC will periodically re-evaluate rates. The program costs are recoverable in utility rates and utility-owned systems are not allowed to receive the incentive.
The pilot program installation cap is limited to an aggregate cap of 25 megawatts (MW) of solar photovoltaics (PV), with a maximum system size cap of 500 kilowatts (kW). The aggregate program cap will be spread equally over four years, with 6.25 MW of capacity being eligible to receive the incentive each year. The aggregate cap is divided up by utility based on 2008 retail sales revenue. PGE has a cap of 14.9 MW, Pacific Power has a cap of 9.8 MW, and Idaho Power has a cap of 0.4 MW. Idaho Power's program is limited to residential installations. Rates differ by system size and geographic zone. Small- and medium-scale systems participate in a program that is modeled after net metering and larger-scale systems participate in a competitive bidding program. Participating PV systems must be grid-connected, metered and meet all applicable codes and regulations. Systems must be "permanently installed" and must remain in service for the entire useful life.
Systems sized 100 kW or less can participate in the portion of the program based on net metering. Generating capacity of 20 MW of the aggregate cap is reserved for the net metering portion, with 12 MW available for residential and 8 MW available for small commercial systems. These residential and small commercial systems are paid for the amount of electricity generated, up to the amount of electricity consumed. In essence, customers are paid for the amount of utility electric load consumption that is offset by on-site solar photovoltaic generation. Unlike typical feed-in tariffs, customers can consume the electricity generated on-site and receive a production incentive – or a volumetric incentive payment – for the amount of electricity generated and consumed. To remove a perverse incentive to increase electricity consumption to receive a greater payment, the system must be appropriately sized to meet average electricity consumption. The rates are determined by the PUC and are based on annual system cost and annual energy output, differentiated by geographic zones. The cost estimates are based on installation data from Energy Trust of Oregon. The volumetric incentive rates are not the actual rates paid to the customer-generator; the actual rate paid is the volumetric incentive rate minus the retail rate. The volumetric incentive rates will be re-evaluated every six months and may be adjusted if necessary. The rates for the performance-based incentive program range from $0.25/kWh to $0.411/kWh.
Vermont adopted feed-in tariffs on 27 May 2009 as part of the Vermont Energy Act of 2009. Generators must possess a capacity of no more than 2.2 MW, and participation is limited to 50 MW in 2012, a limit that increases by 5 to 10 MW/year to a total of 127.5 MW in 2022. Payments were 24¢/kWh for solar, which was increased to 27.1¢/kWh in March 2012, and are 11.8¢/kWh for wind over 100 kW and 25.3¢/kWh for wind turbines up to 100 kW. Other qualifying technologies include methane, hydro, and biomass. Vermont's SPEED program calls for 20% renewable energy by 2017 and 75% by 2032. The program is fully subscribed, but applications are being taken. Payments are for 25 years.
Puerto Rico 
The net metering program pays the energy fed back to the grid at the same rate it is charged. The rate varies monthly around 23 cents per kilowatt. It is not actually paid but credited to the next month if the production exceeds consumption. At the end of the fiscal year (June) the excess if any is paid at a fixed 10 cents per KW of which 25% is retained for public schools. Then the cycle starts again. To participate in the program a yearly insurance, means for disconnecting the system accessible outside of the building and specific brands of equipment dictated by the government are required. The Puerto Rico Electric Power Authority (PREPA), a government agency, is the sole provider of energy in the island.
