Feed-in tariff for grid-connected solar power systems
What are feed-in tariffs?
A feed-in tariff is a premium rate paid for electricity fed back into the electricity grid from a designated renewable electricity generation source like a rooftop solar PV system or wind turbine. At present, feed-in tariff regulations for renewable energy exist in over 40 countries around the world.

Germany sets the feed in tariff example
Possibly the most famous and successful feed-in tariff laws would be those introduced in Germany over the past 15 years. In 1991 the German government introduced the Electricity Feed Act, legally regulating the feed-in to the grid of electricity generated from renewable resources such as solar power. This Act required utility companies to purchase electricity generated from renewable resources such as domestic solar power systems at set rates (feed-in tariffs).
The scheme, originally introduced in 1991, was expanded and enhanced in 2000, and has been responsible for the dramatic growth in Germany’s renewable energy market, particularly the solar photovoltaic industry. In the five years from 2000, the quantity of electricity fed into the grid from eligible sources has more than doubled, with a seven-fold increase in installed solar photovoltaic (PV) capacity to over 1,500 MW by the end of 2005. By comparison, at the same time Australia had in the order of 7MW of grid-connected solar power, or less than 0.5% of Germany’s capacity. Germany has continued to grow it's solar market and currently has around 2,500 MW of solar power capacity.
Based on exchange rates as of mid-February 2009 and under the new tariff structure introduced in 2004, the base level of compensation for grid connected solar power installations on homes and buildings is up to AUD$ 1.12 per kWh.

Australia is lagging behind other countries such as Germany who, while having half the sunshine of Australia, have 200 times the solar production capacity of our country due to a generous feed in tariff program.
Gross vs. net feed in tariff
A net feed in tariff, also known as export metering, pays the PV system owner only for surplus energy they produce; whereas a gross feed in tariff pays for each kilowatt hour produced by a grid connected system. It's a very important difference.
Is an income from a feed in tariff taxable?
At this point, there doesn't appear to be any specific taxation legislation dealing with income derived from feed in tariffs. Whether it is assessable income depends on the income producing nature of the activity. If it can be demonstrated that the system was installed with a view to making a profit, then receipts under the feed in tariff would be considered assessable income while all expenses associated with the income generating activity would be deductible (eg depreciation).
In most cases, systems installed at domestic sites would not be taxable as they
would be considered personal use / hobby (i.e. not in the nature of a business
or profit making scheme). If the system is installed at a commercial site, it
will most likely be considered taxable. However, system owners should consult
their accountant for advice or can also request a private
ruling from the ATO. An example of an ATO private ruling result in relation
to feed in tariffs can

Feed in tariff income and social security
According to a May 2010 announcement from Centrelink, feed in tariff credits where applied as a credit on an electricity account are not included in Centrelink's income test for pensioners, but credits converted to cash payments such as a cheque or direct deposit will be. The adjusted policy applies from 14 May 2010 and is relevant to not just pensions, but all Social Security income support payments such as NewStart. However, we are still unclear if this applies to payments such as Family Tax Allowance and Parenting Payments. We are currently seeking clarification and advise people who may be affected should consult with their local Centrelink Office.
Is GST payable on feed in tariff revenue?
Individuals will not need to pay/remit GST from their feed in tariff income. The reason being that selling electricity back to the utility providers is considered an enterprise but you need to receive $75k per annum from this source to be required to register for GST. However, businesses will need to pay/remit GST for their feed in tariff income.
Victoria net feed in tariff
Victorian households with solar power systems will be paid a feed in tariff from November 2009. Legislation for the Victorian feed in tariff was introduced on March 10, 2009; then revised and passed on June 25, 2009.
Under the program, Victorian households, community organisations and small businesses who consume less than 100 megawatt hours of electricity a year will be credited a minimum 60 cents for every unused kilowatt hour of power fed back into the state electricity grid. Some electricity retailers may offer a higher amount.
While electricity companies are only obliged to offer the 60c rate and as only a 12 month credit, some are now offering cash payments at higher rates:

| *As at December 9 2009. Information obtained through sales consultants and data from official company websites | |||||
The tariff will only be available until a total capacity of systems participating reaches 100 megawatts total capacity.
PV systems larger than 5 kilowatts in size and other renewable energy systems up to 100 kilowatts in size remain eligible for the standard feed-in tariff. On July 21, the Victorian Government also announced new initiatives for medium and large scale solar power installations - details to be come.
PFiT vs SFiT in Victoria
In Victoria, electricity distributors (upstream from electricity retailers) Powercor and Citipower have created confusion regarding FiT issues by introducing their own terminology PFiT and SFiT, which stand for Premium Feed In Tariff and Standard Feed In Tariff.
These are simply acronyms these distributors are using to describe the following.
Essentially, PFiT and SFiT are two different options offered to solar power system owners with different rates for electricity consumed, depending upon usage pattern. However, both options still offer the premium feed in tariff for power generated and the amount paid varies between retailers; the minimum being 60 cents per kilowatt hour for surplus electricity exported to the grid per government legislation .
PFiT vs SFiT - what should you choose for consumption?
Bearing in mind the PFiT and the SFiT options have been imposed at the electricity distributor level, the general rule of thumb is:
- If you have more than one meter and its being used to operate appliances during daytime such as dual element electric hot water, underfloor slab heating or an air conditioner, then you are likely best to choose the standard feed in tariff option (SFiT)
- If you have two meters & one applies to a single element HW system you will likely benefit most from the premium feed in tariff (PFIT) option.
- If you have one meter, then you would likely be best to opt for a premium FiT (PFiT)
Which distributor should you choose?
Unfortunately, you have no choice. A distributor is assigned to specific geographic areas:
Citipower
CitiPower distributes electricity to Melbourne's CBD and inner suburbs.
Jemena
Jemena Electricity Networks distribute electricity to the north-west greater metropolitan region of Melbourne.
Powercor Australia
Supplies electricity to Melbourne's outer western suburbs and regional and rural centres in the central and western areas including Ballarat, Bendigo and Geelong.
SP Ausnet
Supplies electricity to eastern metropolitan Melbourne and eastern Victoria.
United Energy Distribution
Supplies electricity to south-east Melbourne metropolitan area and the Mornington Peninsula.
Which retailer should you choose?
While you cannot change distributors, you can switch retailers.
At the electricity retailer level, whether it is Victoria or any other state, we always suggest for people to
shop around some retailers are far more solar friendly than others and will offer better rates, higher payments for the power your system produces and/or better arrangements regarding your account generally.

South Australia net feed in tariff
From July 1 2008, qualifying South Australian residents began receiving $0.44 per kilowatt-hour. On August 31 2010, Premier Mike Rann announced amendments to the scheme to increase the rate paid to 54c per kilowatt hour minimum.
The feed in tariff program is available to all qualifying South Australian residents, regardless of the electricity company that provides power to their premises. The start date of the amended scheme has not yet been announced. Until that time, we assume the 44c per kilowatt hour will apply.
Under the amended scheme, additional eligibility criteria will be introduced, including:
- Payment of the bonus limited to the first 45 kilowatt hours exported to the grid per day (far higher than what an average system would produce)
- A limit on eligibility to one generator per customer or entity
- Exclusion generators operated primarily for the purpose of generating a profit from the scheme
- The scheme will be closed to new connections when an installed capacity of 60MW is reached.

ACT gross feed in tariff
In July 2008, legislation was passed in the ACT's Legislative Assembly for a gross feed in tariff to be implemented and originally paid 50.05c/kWh for systems up to 10kw capacity and 40.04c/kWh for up to 30kW capacity. The program was revised in April 2010; from 50.05c/kW to 45.7c/kWh for all systems up to 30kW capacity installed from July 1 and that price will remain in place for two years. All contracts are valid for 20 years from the date of contract.

Western Australia gross feed in tariff
After previously announcing a rate of $0.60 per kilowatt hour based on a gross model starting some time in 2009, the Western Australian government rescinded the rates and conditions in June 2009 and decided on a net feed in tariff model.
On May 27, 2010, the Western Australian Government announced the Residential Net Feed-in Tariff Scheme will commence August 1, 2010 and pay a rate of 40 c/kWh for net electricity exported to the mains grid; in addition to any schemes offered by electricity retailers.
Residential Net Feed-in Tariff Scheme participants will receive the premium rate for 10 years. Solar power systems will be limited in size to 5kW for Synergy customers and 10kW per phase (30kW in total) for Horizon Power customers.
The feed in tariff is in addition to the price paid by Synergy and Horizon Power under the Renewable Energy Buyback Scheme.

Queensland net feed in tariff
The Queensland Government Solar Bonus Scheme commenced on 1 July 2008. Grid connect solar owners participating in the scheme will be paid $0.44 per kilowatt hour (kWh) for surplus electricity fed into the grid, plus local electricity companies may choose to over additional payments above that.
A 10kW limit applies to each phase of power supply. If you have 3 phase power, it would be possible to set up 3 separate 10kW systems and still get paid the 44c for every kWh fed into the grid. This tariff is open to residential, business and community buildings.

New South Wales gross feed in tariff
The New South Wales Government originally announced details of the state's feed in tariff incentive (called the Solar Bonus Scheme) on June 23, 2009, but on November 9 2009, made a decision to switch from a net feed in tariff to the gross model; a much more generous arrangement.
Pays 60 c/KWh on a gross basis
Maximum system size 10 kW
Commences 1 January 2010
Review triggered at 50MW installed capacity
NEWSFLASH August 25, 2010: The NSW Solar Bonus Scheme is now under review. Households in NSW with new connections can continue to apply for and receive the current Solar Bonus Scheme feed-in tariff rate of 60c per kilowatt hour until (and if) any legislative changes are made as a result of the review.
NSW gross feed in tariff and electricity meters
According to the information we have on hand, current as at late December 2009, there are 3 distributors who will all be handling the GFiT separately;
a) Integral (West & South Sydney) - Integral meters can be reprogrammed and the
gross feed in tariff will be offered from 1/1/2010. Customers must apply for the
gross feed in tariff and may need to pay a fee.
b) Energy Australia (North Sydney) The gross feed in tariff will not commence
until 1/7/2010 for Energy Australia customers, but the net feed in tariff will be available before this time.
Energy Australia's meters cannot be reprogrammed. Customers will need to change to a net meter on 1/1/2010 and then to a gross meter on or around 1/7/2010. It is likely that customers will need to pay for 2 meter
changeovers.
c) Country Energy (the rest of NSW) As per Energy Australia; the only
difference being since January 1 2010, all grid interactive metering became contestable works.
This means that although there is no charge for the meter, customers are asked to engage a level 2
Accredited Service Provider (ASP) to complete the installation of the meters. This will
incur a varied cost.

Why do we need feed-in tariffs?
Residential solar power is disadvantaged in Australia. The market fails to take into account the true value and many benefits to the electricity network which arise from the adoption of renewable energy technologies embedded within the electricity grid.
Solar PV, like other renewable energy sources, provide environmental benefits through reduced atmospheric pollution, and social benefits through industry development and job creation - for example through the installation of grid connect solar systems, each with related economic benefit.
When electricity is transmitted over a distance, some is lost through what's called line loss. By installing rooftop solar arrays on houses, the electricity can supply not only the house on which it's installed, but the surplus can feed other houses close by.
Centralised power generation facilities also provide a relatively easy target for hostile parties and can be destroyed in natural disasters such as cyclones or fires. A decentralised network or grid connected systems allows for better energy security as it's much cheaper and faster to repair a sub-station than it is to replace an entire plant. It's in the interests of our national security to decentralise power generation.
During the summer months, it's becoming increasingly common for blackouts to occur due to an overload of the mains grid. It's during these months that solar power installations can make their greatest contribution.
A feed-in tariff for grid connected systems redresses these systemic market failures and threats and rewards solar electric generation for its true value to the electricity market and wider society, by providing a financial incentive for the adoption of renewable energy.
Design of a feed-in tariff scheme
For a feed-in tariff to be effective, it is essential that the tariff offered is designed in a way as to adequately reward solar PV proponents. Energy Matters believes that in order to provide an incentive for people to install grid-connected solar systems, and thus achieve the goals of the scheme, there are three key elements of a feed-in mechanism which need to be considered: The price level of the tariff; the means of metering; and the duration of the scheme. It is the proper combination of these three elements, which will determine the success or failure of a feed-in mechanism.
Energy Matters strongly believes that an effective scheme would involve a feed-in tariff of at least 80 cents per kWh, paid on the entire output of a solar power system (via gross production metering), and offered for at least 15 years. Only a gross feed-in tariff set at or above these levels would adequately reward the adoption of solar PV for the range of environmental, social and economic benefits arising from this technology, and encourage the uptake at sufficient levels to achieve the policy goals.
It is important that the 80 cents per kWh gross production feed-in tariff is established in conjunction with the Australian Commonwealth Government’s Solar Homes and Communities Plan. Only then will a feed-in tariff scheme be effective in encouraging uptake of rooftop solar photovoltaic systems by helping owners to recoup the cost of their system.
However, for any feed-in tariff to totally phase out the federal means-tested $8000 rebate scheme, we believe a feed-in tariff mandated at 80 cents per kWh would be more effective and there should be a crossover period where the rebate is still available.
Although several states in Australia already have feed-in tariff schemes in place, those introduced in South Australia, Queensland and Victoria recently are net feed-in tariffs, meaning they only pay homeowners for the electricity exported to the grid minus what is consumed in the home at the time of production. This system of metering significantly discriminates against both owners of smaller grid-connected systems and those who are more likely to consume electricity during the day, such as pensioners or stay-at-home parents.
Alternatively, double incomes families who are typically away from home during the day manage fine under net metering, but now it is these households who have become ineligible for the solar rebate, due to the $100 000 per household income means test.
Energy Matters' feed in tariff standpoint
At Energy Matters we believe that for a feed-in tariff scheme to make the most impact in Australia it must be a gross feed-in tariff. When Germany introduced gross feed-in tariffs in 2000 it doubled the amount of electricity generated from renewable energy sources and adjusted its 2010 target of 12.5% of total energy consumption. It is now three years ahead of schedule.
As a consequence of this success, Germany recently increased its renewable energy target to 27% of all electricity generation by 2020. Also the gross feed-in tariff has created nearly 250,000 new jobs in the renewable energy industry, which will soon surpass the car industry as that nation’s number one employer. The German solar power sector is now creating three times the number of jobs per installed megawatt as the coal fired electricity industry - all of this in a country receiving half the sunshine Australia does.
International experience tells us that gross feed-in tariffs can be very successful in stimulating the uptake of renewable energy, addressing climate change and creating strong local industries and employment. However our state governments, through inventing a net feed-in tariff have made a fine mess of a policy, which has delivered so much for the solar power industry overseas.
How you can help
If you care about fighting climate change, cutting Australia’s greenhouse gas emissions and encouraging our domestic renewable energy industry then please write to your local State or Federal members of Parliament requesting they consider gross feed-in tariffs as the most effective way to increase solar power use in Australia.
You can also sign our petition at FeedInTariff.com.au! Your voice will be heard!
By introducing these incentives we will encourage the installation of solar panels on more homes around the country and increase the output and generation of clean renewable energy.
International feed in tariffs
Feed in tariffs are increasingly being implemented around the world as they are a proven means to stimulate renewable energy uptake without impacting on the public purse. Tariff Watch on PV-Tech's web site keeps track of the efforts and schemes in various countries; and allows you to compare programs between nations and states within.
