Options for gaining financial benefits from your RECs

The expanded Renewable Energy Target (RET) scheme does not provide a rebate or feed-in tariff. The purchase of a SGU may entitle you to renewable energy certificates (RECs) if your SGU is eligible. These certificates can then be sold and transferred to liable parties on a market based online system called the REC Registry.

For more information about RET visit - RET - the basics
For more information about rebates and feed-in tariffs for SGUs contact your State Government or agent/retailer/installer.

  • You must be the owner of the system at the time it is installed to be entitled to assign RECs to an agent or create RECs in the REC Registry. In some circumstances where the SGUs are installed in new buildings, this can be the builder or property developer.

There are two options for reimbursement of your RECs under the RET scheme:

Option 1 - Agent Assisted
Find an agent and assign your RECs to the agent in exchange for a financial benefit which could be in the form of a delayed cash payment or upfront discount on your SGU. A majority of owners take this option.

Option 2 - Individual Trading
Create the RECs yourself. Find a buyer then sell and transfer them in the REC Registry.

RECs defined

A renewable energy certificate (REC) is a commodity in the REC market. RECs are created by eligible parties and sold to liable parties via the REC Registry to meet their liability under the RET.

SGU process - Options for gaining financial benefits from your RECs

Diagram showing two options for the sgu process

Option 1 - Agent Assisted

A majority of owners of SGUs find it convenient to assign their rights to create RECs at the point of purchase to a registered agent. A registered agent will:

  • Determine whether your SGU is eligible for the RET
  • Determine for you how many RECs your SGU is entitled to under the RET scheme
  • Offer a financial benefit to you. This may be in the form of a cash payment or discount on your SGU.

If your system is installed on or after 9 June 2009 it may be eligible for additional RECs under Solar Credits. The multiplication for additional RECs under Solar Credits is as follows.

Installation Period Multiplication
9 June 2009 - 30 June 2010 5 x
1 July 2010 - 30 June 2011 5 x
1 July 2011 - 30 June 2012 5 x
1 July 2012 - 30 June 2013 4 x
1 July 2013 - 30 June 2014 3 x
1 July 2014 - 30 June 2015 2 x

Your agent should factor this multiplication into your REC calculation and resulting financial benefit. Your agent will determine the eligibility of your system but if you wish to understand the eligibility criteria for Solar Credits see Option 2: Individual Trading/Step 4: Determine if your system is eligible for Solar Credits.

If you would like to determine the approximate number of RECs that your system could receive under the RET the REC Registry contains a Small Generation Unit REC Calculator.

Visit - Small Generation Unit REC Calculator

It is important to note that agents list different prices and payment processes for RECs. After buying the RECs from you the agent will register your RECs and usually bundle them with other small generation unit and solar water heater RECs for sale and transfer in the REC Registry.

  • The ORER recommends that SGU owners contact a range of agents before entering into any contractual agreement.
    Visit - List of registered agents

Before entering into any contractual arrangement to assign your right to create RECs:

  • Make sure you are satisfied with the financial benefit and the date of payment the agent is offering for your RECs.
  • Check that details are recorded in writing through a REC assignment form that should be provided by your agent.

If you experience a delay in receiving payment for your RECs contact the agent you have agreed to sell them to.

  • ORER does not set the price of RECs nor does it get involved in disputes between buyers and sellers. Payment for RECs or the rights to create RECs is a contractual matter between the buyer and seller.

Option 2 - Individual Trading

  • As this process is relatively complex a majority of owners assign their RECs to an agent. For information on how to engage an agent see – Option 1: Agent Assisted

Step 1: Determine if your system is an SGU or power station

Compare your system's kW capacity against the following criteria to determine if your system is an SGU or power station

System type System capacity and annual electricity output Installation periods
Small wind turbines No more than 10 kW and a total annual electricity output less than 25 MWh On or after 1 April 2001
Solar (photovoltaic) systems No more than 100 kW and a total annual electricity output less than 250 MWh On or after 14 November 2005
Solar (photovoltaic)systems No more than 10 kW and a total annual electricity output less than 25 MWh Between 1 April 2001 and 13 November 2005
Hydroelectric systems No more than 6.4 kW and a total annual electricity output less than 25 MWh On or after 1 April 2001

If the kW rating or MWh generation for a SGU is above the respective thresholds or if the unit was installed prior to 1 April 2001, it is not eligible to have RECs created for it as a SGU. However, it may be eligible for accreditation as a renewable energy power station.

Upon installation of a small hydro, small wind or small solar (photovoltaic) system with a capacity of less than the prescribed threshold for a small generation unit RECs may be created under the legislation as if the system were a small generation unit.

Any subsequent installation of additional capacity with the effect that the total capacity of the system exceeds the prescribed threshold of capacity for a small generation unit, will mean the system is no longer a small generation unit. The operator of the system may apply for accreditation of the system as a power station and if the system satisfies the requirements for accreditation then the Regulator will accredit it.

However, RECs may not be created for electricity generated by that part of the power station that was the ‘small generation unit’ as originally installed, and for which RECs were created. The nominated person for the power station will need to determine what proportion of electricity generated by the whole power station was generated by the 'old' small generation unit and deduct that electricity from the total electricity generated by the power station. The nominated person will then only be able to create RECs for that portion of electricity generated by the 'extended' part of the power station.

Information on the power station accreditation process is available on the power stations page of the ORER website.

If your system meets the above eligibility criteria go to Step 2.

Step 2: Check if your SGU installation is within the time limit for creating RECs

Time limits for the creation of RECs for SGUs may apply depending on their installation date and SGU type. If the installation date and REC creation time limit for your SGU falls outside of the following thresholds your system is not eligible to create RECs.

SGU installation date Deeming period SGU type REC creation time limit
On or before 6 October 2007 1 or 5 years Wind, solar (photovoltaic), hydro Anytime after installation
On or after 6 October 2007 First deeming period (1 or 5 years) Wind, hydro Within 12 months of the installation date
On or after 6 October 2007 First deeming period (1, 5 or 15 years) Solar (photovoltaic) Within 12 months of the installation date

Step 3: Establish the deeming period for your SGU

If your SGU meets the eligibility requirements you can establish the deeming period for your SGU. RECs may be created for SGUs in batches, for either 1, 5 or 15 year deeming periods, depending on the particular installation. At the beginning of each subsequent deeming period, the Regulator must be satisfied that the SGU is still installed and is likely to remain functional for the next deeming period. The ORER may request evidence to support this claim.

RECs may be created for wind and hydro SGUs either:

  • annually; or
  • on installation for the first 5 years after the installation (the deeming period) and then at the start of each subsequent 5 year deeming period.

RECs may be created for solar (photovoltaic) SGUs either:

  • annually; or
  • on installation for the first 5 years after installation (the deeming period) and then at the start of each subsequent 5 year deeming period; or
  • on installation for 15 years (the deeming period) - no further RECs may be created. Special eligibility requirements are associated with the 15-year deeming option. The system needs to be design and installed by an accredited Clean Energy Council (CEC) installer for stand-alone and grid-connected power systems.

Step 4: Determine if your system is eligible for Solar Credits

Solar Credits is a mechanism under the expanded RET which multiplies the number of RECs able to be created for eligible installations of SGUs.

There is not means testing for Solar Credits under the legislation.

Solar credits will apply to the first 1.5 kilowatts (kW) of capacity installed. Generation from capacity above 1.5 kW will still be eligible for the standard 1:1 rate of REC creation.

Eligibility requirements are as follows:

  • the small generation unit in respect of which the certificates are created is installed at eligible premises between 9 June 2009 and 30 June 2015.
  • at the time the small generation unit is installed at the eligible premises, there is no pre-approval or funding agreement in force in respect of the unit under the Solar Homes and Communities Plan (SHCP), the Renewable Remote Power Generation (RRPGP), or the National Solar Schools Program (NSSP) and no financial assistance has been provided in respect of the unit under the SHCP, the RRPGP or the NSSP.
  • at the time the small generation unit is installed at the eligible premises, financial assistance under the SHCP, the Photovoltaic Rebate Programme (PVRP), the RRPGP or the NSSP has not been approved or provided in respect of any other small generation unit at the eligible premises.
  • the small generation unit is a new and complete unit. A system is a complete unit if:
    • the unit is capable of generating electricity in a form that is usable at the eligible premises where it is installed without the need for an additional part or parts to be added to or incorporated into the unit.
    • the unit is wired directly to the eligible premises where the unit is installed so that its output is capable of being metered at the premises or the unit includes a meter that is dedicated to measuring the electricity output of the unit.
  • at the time the small generation unit is installed at eligible premises, certificates have not been multiplied in respect of any small generation unit at the premises and:
    • on one occasion only, irrespective of whether the certificates are created for a 1-year, 5-year or 15-year period; and
    • only if the certificates relate to the first 1.5 kW of the rated power output of the unit.

The multiplication for additional RECs under Solar Credits is as follows. See REC calculations.

1 July 2014 - 30 June 2015 2 x

Definition of an eligible premises

Regulation 20AA covers the circumstances in which Solar Credits can be claimed. Solar Credits can only be claimed for one small generation unit installed at each ‘eligible premises’.
‘Eligible premises’ is defined in the Regulations to mean any of the following:

  • a house (including the land on which the house is located and any outbuildings on the land)
  • a townhouse
  • a residential apartment
  • a shop (including the land on which the shop is located and any outbuildings on the land)
  • other premises located at an address

An outbuilding is a detached building subordinate to a main building and is not considered to be an eligible premises in its own right.

House
A house is an eligible premises. For a house that is an eligible premises:

  • a home office located in the house or in an outbuilding on the land where the house is located; or
  • a business operated from the house or in an outbuilding on the land where the house is located;

is not a separate eligible premises.

Townhouse, residential apartment
A townhouse, residential flat, unit or apartment is an eligible premises including those located in a:

  • multi-story apartment building; or
  • retirement village (this does not include a room in a nursing home, hostel or similar assisted living facility).

For a townhouse, residential flat, unit or apartment that is an eligible premises:

  • a home office located in the townhouse, residential flat, unit or apartment; or
  • a business operated from the townhouse, residential flat, unit or apartment;

 is not a separate eligible premises.

Shop
A shop is an eligible premises (except when located in a house (land or outbuilding), townhouse, residential flat, unit or apartment that is itself an eligible premises – see above).  Each shop in a shopping mall or other multi-shop type complex is an eligible premises.

Other premises located at an address
Business premises (eg factories and offices)
Each separate business which is located at an address will be a ‘premises located at an address’ (except when located in a house (land or outbuilding), townhouse, residential flat, unit or apartment that is itself an eligible premises). Some businesses may be located at an address which covers several numbers in a street (e.g. a factory might be at 42-56 Smith Street). In such a situation, there is only one eligible premises.

Alternatively, some businesses will occupy a separate unit at a single street address, where a different business is carried out in the separate units, (e.g. Unit 2 of 56 Smith Street). Each unit is a separate eligible premises.

Specific types of premises
Each of the following types of businesses are regarded as a single eligible premises:

  • a motel, hotel, resort or caravan park (each room/cabin/villa etc  in a motel, hotel or resort and each stationary caravan in a caravan park is not a separate eligible premises)
  • a nursing home, hostel (each room is not a separate eligible premises)
  • a hospital
  • a restaurant

Community and educational buildings
The building(s) located at an address where a community group or institution carries out its activities (including the land on which the building is located and any outbuildings on the land) is a single eligible premises (eg a scout hall, guides hall, sporting club, school, church or other religious building).  In the situation where the building(s) is or are used by more than one organisation, there is one eligible premises only.

More than one premises located at a single address
Where more than one separate premises (excluding outbuildings) is located at a single address, all of those premises are separate eligible premises. Examples might include a:

  • dairy on a farm that is separate to the residential house on the same farm — both premises are eligible premises;
  • owner/manager’s house that is separate to the rest of a caravan park but at the same address — the house is a separate eligible premises to the caravan park;
  • green keeper’s house that is separate to the rest of the golf course at the same address  — the house and the business premises are separate eligible premises.

To be another 'eligible premises' at a single address, the premises must be clearly separate from the other eligible premises located at the address (e.g. the house). A building is not an eligible premises if it is an outbuilding associated with a house. For example:

  • a garage, studio or other small building situated in close proximity to a house which itself is an eligible premises (where a small business may be carried out) is as an outbuilding and not another eligible premises;
  • a larger business premises that is not subordinate to a house which itself is an eligible premises,  and which more commonly is located further from the house than is usual for a garage or studio, is not an outbuilding and therefore is a separate eligible premises.

Structures that are not eligible premises
The following structures are NOT eligible premises:

  • street lights, street signs, mobile phone towers, boats, cars and trailers; and
  • mobile homes, caravans or similar wheeled vehicles not intended to be permanently attached to the land (these are not defined as eligible premises because they do not remain at a location for a long period of time).

Premises that are not eligible
If you would like clarification regarding the eligibility of a particular premises, please contact the Small Units Team at the ORER via email orer@orer.gov.au.  Include in your email as much detail as possible including location, address, boundaries, road access, title information, access to electrical connection and metering, ownership, occupancy, nature of business, maps and other information you may wish to provide.

  • If a system is not eligible for Solar Credits the system can still create RECs with the standard 1:1 rate of REC calculation.

Step 5: Determine how many RECs your SGU is entitled to

Installations of SGUs are deemed to be eligible for RECs based on rated power output (kilowatt capacity), eligibility for Solar Credits and geographic location or resource availability.

If you would like to determine the approximate number of RECs that your system could receive under the RET the REC Registry contains a Small Generation Unit REC Calculator.

Visit - Small Generation Unit REC Calculator

To determine the number of RECs for your system is entitled to see:

Step 6: Become a registered person in the online REC Registry

Once you know the number of RECs you are entitled to you will need to become a registered person in the REC Registry, an internet based registry system that:

  • maintains various registers (as set in the Act)
  • facilitates the creation, registration, transfer and surrender of RECs

A registered person can create, sell and transfer RECs in the REC Registry. To become a registered person in the REC Registry you will need to:

  1. Create an account on the REC Registry. See the Apply for an Account link on bottom right of the REC Registry home page.
    Visit - REC Registry
  2. Complete an Application for Registration and send it to the ORER.
    Visit - Application for Registration
  3. The ORER will notify you via phone when your Application for Registration has been approved and explain the REC Registry process.
  4. Pay a $20 registration fee to complete the registration process.

    Please DO NOT send any payment to the ORER with this application form - payment of the $20 registration fee is made via your account in the REC Registry. The application fee is GST exempt.

Step 7: Create RECs through the REC Registry

Once your application has been approved you are ready to complete the registration process online and create RECs for your SGU installation.

Visit - REC Registry

The main details required to create RECs include the following:

  • Type of system - solar, wind, hydro
  • System brand
  • System model
  • Panel serial numbers (solar only)
  • Number of panels (solar only)
  • Equipment module serial number (wind and hydro only)
  • Resource availability (wind and hydro only)
  • Rated power output (in kW)
  • Installation date
  • Installation address
  • Installer's details
  • Owner's details

The REC registry contains online help screens and a REC Registry Support Desk to assist in the use of the Registry.

Step 8: Wait while your RECs are validated

Once you have created your RECs, they will be validated by an ORER officer to ensure they have been created correctly. This can take up to 4 weeks. When your RECs have passed the ORER validation, they will become 'Registered'. Registered RECs are able to be sold and transferred in the REC Registry, and surrendered either voluntarily or meet a liability under the Renewable Energy Electricity (Act) 2000. If the RECs are not correctly created they are failed by ORER.

Visit - REC Registry

Step 9: Find a buyer for your RECs. Sell your RECs and transfer them in the REC Registry

  • You do not have to sell your registered RECs at all, but if you wish to create RECs for your SGU installation you must create them within 12 months of the date of installation of the system.

If you wish to sell your RECs, it is your responsibility to find a buyer and negotiate the price and other terms of sale. Potential buyers may include:

  • electricity retailers who may need to purchase RECs to meet their REC liability
  • registered agents for deemed units, who create and trade RECs from SGUs
  • traders of RECs

Price and payment date should be key considerations when negotiating the sale of your RECs. You should ensure that:

  • you are satisfied with the price and payment date your receive for your RECs
  • details are recorded in writing before entering any contractual arrangement to sell your RECs.

Once you have found a buyer and negotiated the terms of sale, you will need to transfer the RECs to the buyer through the REC Registry and arrange payment outside the REC Registry. The ORER does not set the price of RECs nor does it get involved in disputes between buyers and sellers. Payment for RECs or the rights to create RECs is a contractual matter between the buyer and seller.

REC Calculation

Calculating RECs for small hydroelectric systems and small wind turbines

The number of RECs that you are eligible to create for your small hydroelectric system or wind turbine is determined by the rated capacity of the system and the number of hours the system can operate at that capacity (resource availability).

To establish how many RECs you may be eligible to create from your system you should undertake the following steps:

  1. Establish your resource availability. If you do not know the actual resource availability, then you must claim for the default amount, which is:
    • Hydroelectric - 4000 hours/year
    • Wind - 2000 hours/year
    If you claim for resource availability above the default amount, then you must provide and retain copies of site-specific audit reports and advise the ORER of the name and contact details of the person or company that conducted the audit.
  2. Establish the rated output of your system in kilowatts (kW). You can find the rated power output of your system in the specifications provided by the system manufacturer. Please ensure that you use the exact figure that applies to your particular make and model.
  3. To calculate the annual number of RECs your system is eligible for you multiply the rated power output (in kW) of your system by 0.00095, multiplied by the resource availability of your system (eg. 8kW x 0.00095 x 4000 (or 2000 for wind) hours/year).

  4. If your system’s rated output is greater than 25 MWh (ie. generates more than 25 MWh of electricity) your system is classified as a power station and you cannot assign RECs to an agent. To apply to ORER to become an accredited power station visit the power station page of the ORER website.
  5. If your calculated number of eligible RECs, over a one-year or five-year period, is:
    1. greater than 1 MWh you must round down the calculated number to the nearest whole number of RECs.
    2. between 0.5 MWh and 1 MWh you are allowed to round up the calculated decimal number to 1 REC.

Calculating RECs for small hydroelectric systems and small wind turbines with Solar Credits

The number of RECs that you are eligible to create for your small hydroelectric system or wind turbine is determined by the rated capacity of the system and the number of hours the system can operate at that capacity (resource availability).

Systems that are eligible for Solar Credits are able to create additional RECs based upon the calculation methodology below. If you unsure of eligibility see Step 4: Determine if your system is eligible for Solar Credits.

To establish how many RECs you may be eligible to create from your system you should undertake the following steps:

  1. Establish your resource availability. If you do not know the actual resource availability, then you must claim for the default amount, which is:

  6. If your calculated number of eligible RECs, over a one-year or five-year period, is:
    • greater than 1 MWh you must round down the calculated number to the nearest whole number of RECs.
    • between 0.5 MWh and 1 MWh you are allowed to round up the calculated decimal number to 1 REC.

Calculating RECs for small solar (photovoltaic) systems

Once you have established that a small solar (photovoltaic) system meets the above eligibility requirements, to calculate how many certificates that may be created for it:

  1. Establish your Zone by using Table 2, Ratings and Postcode Zones for Small Solar (Photovoltaic) Systems.
  2. Once you have established your Zone, look up the corresponding Zone Rating in Table 3, Zone ratings for solar (photovoltaic) Systems.
  3. To calculate your system's annual REC entitlement, multiply the Zone Rating by your SGU's rated power output (in kW). You can find the rated power output of your unit in the specifications provided by the manufacturer - please ensure that you use the exact figure that applies to your particular model.

  5. Choose the deeming period you for which you would like to create RECs: 1-year, 5-years or 15-years, as described in Step 3: Establish the deeming period of your SGU.

    Calculate the REC entitlement for each deeming period by multiplying the Annual REC Entitlement (as calculated in step 3) by the number of years in the deeming period you choose, either 1, 5 or 15.
  6. If your calculated REC entitlement, over a one-year or five-year period, is not a whole number and is:
    • greater than 1 MWh you must round down the calculated number to the nearest whole number of RECs.
    • between 0.5 MWh and 1 MWh you are allowed to round up the calculated decimal number to 1 REC.

REC calculation examples

Example 1 - Small Solar Photovoltaic Systems

If you wish to create RECs for a 15-year deeming period for a small solar panel (photovoltaic) system installed by a Clean Energy Council (CEC) - accredited installer on 9 April 2009 in the postcode area of 2315, which has a rated power output of 2.5 kW. To determine eligibility:

  • Is the small solar panel (photovoltaic) system installed within the last 12 months? Yes
  • Does the system have a rated output of not more than 100 kilowatts (kW) or a total annual output less than 250 MWh? Yes
  • Was the system designed and installed by a person accredited for stand-alone and grid-connected power systems under the Clean Energy Council (CEC) accreditation scheme? Yes

The system meets all of the eligibility requirements, so we can now proceed to calculate the number of RECs it is entitled to create.

  1. Look up the postcode in Table 2 to establish your Postcode Zone: 3
  2. Look up the Postcode Zone in Table 3 to establish your Zone Rating: 1.382
  3. Multiply your Zone Rating by the kW capacity to get the annual REC entitlement:
    1.382 x 2.5kW = 3.455 MWh
  4. Multiple by 15 years to get the total REC entitlement:
    3.455 x 15 years = 51.825 MWh
  5. Round down the total amount of electricity taken to be generated to the last whole MWh to determine the number of RECs you are eligible to create:
    51.825 MWh = 51 RECs
  6. This system is rated at less than 100 kW and has a total annual output of less than 250 MWh per year, it does not need to be accredited as a power station.

Example 2 – Small Solar Photovoltaic Systems under Solar Credits

If you wish to create RECs for a 15-year deeming period for a small solar panel (photovoltaic) system installed by a Clean Energy Council (CEC) – accredited installer on 3 August 2009 in the postcode area of 2315, which has a rated power output of 4.5 kW. To determine eligibility:

  • Is the small solar panel (photovoltaic) system installed on or after 9 June 2009? Yes
  • Is the small solar panel (photovoltaic) system installed within the last 12 months? Yes
  • Does the system have a rated output of not more than 100 kilowatts (kW) or a total annual output less than 250 MWh? Yes
  • Does the system have a total rated power output of more than 1.5 kW? Yes
  • Was the system designed and installed by a person accredited for stand-alone and grid-connected power systems under the Clean Energy Council (CEC) accreditation scheme? Yes
  • Is the system a new and complete unit? Yes
  • Is the system installed at an eligible premises? Yes
  • Is there pre-approval or financial assistance for any small generation unit at your address for a Solar Homes and Communities (SHCP), Photovoltaic Rebate Programme (PVRP), Renewable Remote Power Generation (RRPGP) or National Solar Schools Program (NSSP) rebate? No

The system meets all of the eligibility requirements, so we can now proceed to calculate the number of RECs it is entitled to create.

  1. Look up the postcode in Table 2 to establish your Postcode Zone: 3
  2. Look up the Postcode Zone in Table 3 to establish your Zone Rating: 1.382
  3. Multiply your Zone Rating by 1.5, your chosen deeming period and the multiplied value for Solar Credits Table 4:
    1.382 x 1.5 x 15 x 5 = 155.475 MWh
    This provides you with the total REC entitlement for the first 1.5 kW of capacity installed.
  4. Look up your total rated power output. Minus 1.5 from the total rated power output:
    4.5kW – 1.5 = 3 kW
  5. Multiply this number by the postcode zone rating and the deeming period:
    3 kW x 1.382 x 15 = 62.19 MWh
    This provides you with the total REC entitlement for the remainder of the kW capacity installed.
  6. Add the REC entitlement for the first 1.5 kW of capacity installed and the REC entitlement for the remainder of the kW capacity:
    155.475 kW + 62.19 kW = 217.665 MWh
  7. Round down the total amount of electricity taken to be generated to the last whole MWh to determine the number of RECs you are eligible to create:
    217.665 MWh = 217 RECs
  8. This system is rated at less than 100 kW and has a total annual output of less than 250 MWh per year, it does not need to be accredited as a power station.

Example 3 - Small Wind Turbines

If you wished to create RECs on a 5-year basis for a system that has a rating of 2.9 kW and a wind resource availability of 2,000 hours, you must:

  1. Multiply 0.00095 by the kW capacity and the wind resource availability:
    0.00095 x 2.9 x 2000 = 5.51 MWh
  2. Multiply the annual electricity output by the number of years:
    5.51 x 5 = 27.55 MWh
  3. Round down the total electricity output to the last whole MWh to determine the number of RECs you are eligible to create:
    27.55 = 27 RECs
  4. This wind turbine has a total annual output of less than 25 MWh, it does not need to be accredited as a power station.

Example 4 - Small Wind Turbines under Solar Credits

If you wished to create RECs on a 5-year basis for a system that has a rating of 2.9 kW and a wind resource availability of 2,000 hours, you must:

  1. Multiply 0.00095 by 1.5 by the wind resource availability by the multiplied value by the deeming period:
    0.00095 x 1.5 x 2,000 x 5 x 5 = 71.25 MWh
    This provides you with the total REC entitlement for the first 1.5 kW of capacity installed.
  2. Look up your total rated power output. Minus 1.5 from the total rated power output:
    2.9 – 1.5 = 1.4 kW
  3. Multiply this number by 0.00095 by the wind resource availability and the deeming period:
    0.00095 x 1.4 x 2,000 x 5 = 13.3 MWh
    This provides you with the total REC entitlement for the remainder of the kW capacity installed.
  4. Add the REC entitlement for the first 1.5 kW of capacity installed and the REC entitlement for the remainder of the kW capacity:
    71.25 MWh + 13.3 MWh = 84.55 MWh
  5. Round down the total amount of electricity taken to be generated to the last whole MWh to determine the number of RECs you are eligible to create:
    84.55 MWh = 84 RECs
  6. This wind turbine has a total annual output of less than 25 MWh, it does not need to be accredited as a power station
