Connect solar panels, batteries, renewable energy systems

Connect solar photovoltaic (PV) panels, batteries, wind turbines and other micro embedded generating units (up to 30kVA) to the electricity network. The grid can be a handy source of back-up power when your system is offline for maintenance or isn’t generating.

As part of the connection process, we’ll check if the local network can support your system to work effectively. We’ll also need to establish a new connection contract with you.

Here's how to get your system connected.

1. Choose your system and installer

Talk to system retailers, talk to others who already have systems, and do other research to choose the best system and retailer for your needs. Cheaper may not be better, and bigger may not be better for you.

Most system retailers will also offer to install your system. Ensure the person who installs your system is accredited by the Clean Energy Council.

2. Submit your connection application

To get your system connected to our network, you need to apply for a new connection contract with us. As technical information is required, it’s a good idea to have your system retailer apply for you. Otherwise you, or someone on your behalf, can apply via our Network Online Services.

The information needed to apply is explained in our FAQs and further reading. If you still have questions, you can call our Solar Team on 1300 553 924 (Mon-Fri 7.00am-6.30pm) or email us. Otherwise, you can lodge an enquiry online via our Network Online Services. We will respond within five business days.

There is an option to fast-track (or expedite) your application in some cases – read more below.

When we receive your application, we’ll check if the connection service needed for your system is basic or negotiated. We may also check if the local network can support your new system.

Please note: The person who applies is usually the person we contact during the connection process.

3. Accept our connection offer

Whoever submits your application will also need to accept our connection offer.

We want to help you get your system connected quickly and easily to meet your energy needs. Most of our customers only need a basic connection service.

Basic connection

If your connection service type is basic, it can be fast-tracked when submitting the online application. Just tick the Expedite Application box and your connection contract will automatically be created on the terms of our model standing offer.

If your application is not expedited, we’ll make a basic connection offer within 10 business days (or other date agreed with you). You will have 45 business days to accept our offer.  Your connection contract starts when the offer is accepted.

If you want to negotiate the terms of your connection contract, you can choose to do this through a negotiated connection.

Negotiated connection

If your connection service type is not basic, or you want to negotiate the terms of your connection contract, then it’s classed as negotiated. Additional costs may apply.

We do a technical assessment of most applications classed as negotiated. If our technical assessment finds your proposed system may not work effectively on our network, we’ll send an email advising the options available. Once you choose an option, we’ll arrange for your connection offer to be sent.

We’ll aim to make a negotiated connection offer within 65 business days of your application. You will have 20 business days to accept the offer. Your connection contract starts when the offer is accepted.

Read more about connection service types, offers and contracts under FAQs and further reading below.

4. Install your system

Installation of your system can start once you have accepted our connection offer.

Your system installer must submit a Form A to us as soon as possible after installation is complete. This form requests us to inspect your system and make the relevant changes to your metering. New metering is required on all systems and measures any electricity exported to the grid.

The Form A will also notify your electricity retailer of your new system installation. Your electricity retailer may then contact you to discuss any upfront metering charges as outlined in your connection contract and make any relevant changes to your account (e.g. apply your solar feed-in tariff if you are eligible and will be exporting electricity to the grid).

Important: Your installer must leave your system switched off and you must not switch it on. We’ll switch it on after we’ve inspected it and ensured it’s compliant and safe.

5. We inspect your system

We’ll visit your place to inspect your system and make any required changes to your metering. We’ll also check that your inverter matches the one approved. We don’t need to check the solar panels.

Once we’ve confirmed your system meets safety and electrical standards, we’ll switch it on to complete your connection. We must do this within set timeframes (unless we have to change our network to allow connection of your system).

Please note: We’ll need access to your meter box and your inverter during our visit.

For an easy print summary of this connection process, check out our Connect solar PV or batteries checklist (PDF 693.3 kb).

Please note: If you request information by post, it will take longer.

For your new connection

To get your system connected, we need a Form A from your installer and a service order from your electricity retailer. We’ll then visit to inspect your system and change your metering within the below timeframes (unless we have to change our network to allow connection your system). Your electricity retailer will advise the timeframe for our visit.

CBD or UrbanWithin 5 – 10 business days*
RuralWithin 10 business days
IsolatedWithin 30 business days

* Some areas may appear to be CBD or Urban, but they can be classified as Rural within our network. In these cases, we’ll complete your connection within 10 business days.

How much will it cost?

Connection services charges

Fees and charges will depend on the type of connection service you have applied for, and whether any work is needed on the electricity network to allow connection of your system.

Other charges may apply under a negotiated connection offer. For example, an application fee, a network extension fee, or a capital contribution.

If any charges are required to meet your connection application, an estimate of these charges will be included in your connection offer.

All our connection charges have been approved by the Australian Energy Regulator, including the charges for your ongoing day-to-day access and use of our electricity distribution network, and user-specific distribution services. Read more on connection services charges.

Metering charges

There will be fees to install or enable the required electricity metering at your premises. An estimate of the range of metering charges will be included in your connection offer. The amount is actually charged to you by your electricity retailer may differ and be outside this range.

Read more on metering charges.

Other charges

Your installer or licenced electrical contractor will advise you on any work required to prepare your property for the installation of your system, for example upgrading your switchboard. We recommend you talk to them for more information on the work needed at your place.

FAQs and further reading

If I’m not ready to apply, can I just make an enquiry?

Yes, you can make a preliminary enquiry about your connection. We’ll respond within five business days, or other date agreed with you.

You can either:

I don't want to use an online form, do you have a form I can print?

Yes, we have PDF versions of our connection enquiry form and application form that you can download and print:

What types of systems can I apply to connect?

Solar PV systems, micro-wind turbines, and micro-hydro turbines are all examples of micro embedded generating units (micro EG units). Batteries are also classed as micro EG units as they connect to the electricity network through an inverter.

What is a micro embedded generating unit?

An embedded generating unit is connected directly within an electricity distribution system and does not have direct access to the electricity transmission network.

To be a micro embedded generating unit, it must be fitted with an inverter, such as in a solar PV system (this excludes rotating machines), and be compliant with the technical requirements of AS/NZS 4777.

Previously AS/NZS 4777 only included generators up to 30 kVA.  However, it has recently been changed to cover embedded generators up to 200 kVA. If you are interested in connecting a generating system larger than 30 kVA, please refer to our Major business connections webpage.

What if I want to connect a system greater than 30 kVA?

Read more on how to apply to connect a larger scale embedded generating system (like solar, wind, hydro or diesel) above 30 kVA on our Major business connections webpage.

What information do I need to submit a connection application?

You will need to know the following:

  • Your contact details
  • Your National Metering Identifier (NMI) which you can find on your electricity bill
  • The address details (including your lot and plan number, as on your council rates notice) where the system will be installed
  • Technical details of your chosen system, such as:
    • total capacity of the solar PV panels
    • details of all inverters to be installed, including reactive power control setting
    • number of electrical phases at your premises
    • number of electrical phases your system will be connect to
  • Name and contact details of your sales consultant
  • Name and contact details of your system installer.

What is a basic connection service?

Most applications qualify for a basic connection service. This is where the connection services needed for your new system are relatively simple and straightforward, and include little or no changes to our network.

Systems that qualify for a basic connection service are typically:

  • Exporting inverters rated up to 3.5 kVA single phase, or up to 10 kVA 3 phase, on our main network, or up to 2 kVA on our Single Wire Earth Return (SWER) networks
  • Partial-export inverters limited to 3.5 kVA or less on our main network, or 2 kVA or less on SWER networks
  • Minimal-export (non-exporting) inverters rated up to 5 kVA per phase (or 30 kVA over three phases) on our main network, or up to 10 kVA on SWER networks.

The basic connection services we offer in relation to micro EG units are fully described below.

More detailed information about basic connection services is explained in our schedule to our model standing offer.

What does expedited mean?

If your new system connection is classed as a basic connection service, it can be fast-tracked in the online application. This is called an expedited application.

It simply means that you are requesting to expedite at the time you submit your application, provided we are satisfied that the connection service you are applying for is a basic connection service and that you indicate that the terms in the model standing offer are acceptable to you.  If this occurs, then the contract forms when your application is submitted.

Just tick the Expedite Application box at the end of the online connection application to do this.

If the Expedite Application box isn’t ticked, we’ll make a basic connection offer within 10 business days (or other date agreed with you). You will have 45 business days to accept it.

Your connection contract starts when the offer is accepted.

What is a negotiated connection service?

A negotiated connection service is needed if:

  • Sufficient power supply from our network is not readily available in your area
  • A network change is required to connect your proposed system
  • Your new system connection is classed as a basic connection service but you have chosen to negotiate the terms of your connection contract with us
  • Your new system connection is not classed as a basic connection service, such as the export capacity of your proposed inverter exceeds our network thresholds.

What if my application doesn't pass your assessment?

Most applications do pass our assessment. If yours doesn’t, that means that your proposed system was unlikely to work effectively on our electricity network. The reasons may include one or more of the following: -

  • There are a number of other solar PV systems on the same network transformer as your premises
  • Your local network transformer capacity is too small or other network components are unlikely to support your proposed system
  • Your proposed system connection is a long distance from your network transformer
  • Your service line and/or electricity cables within your property boundary may be too long or not have enough capacity.

Read more about applications that don’t pass assessment and the options.

Standard Connection Services

Although the energy laws provide for standard connection services, we don’t have any standard connection services at present.

More information about connection offers

When your connection application is submitted online, it will immediately be checked to see if it’s for a basic or negotiated connection service.

We will then make a basic or negotiated connection offer within set timeframes for you to accept.

Basic connection offer, expedited

If your connection service type is basic but you don’t expedite your application, we’ll make a basic connection offer within 10 business days (or other date agreed with you). You will have 45 business days to accept it.

The basic connection services that we offer are listed in the schedule to our Model Standing Offer for Micro EG Units (PDF 306.1 kb)

Negotiated connection offer

If your connection service type is not basic, or you choose to negotiate the terms of your connection contract, then it’s classed as negotiated.

Most applications that qualify for a negotiated connection service undergo a technical assessment to check if the local network can support your system to work effectively.

Usually we’ll make a negotiated connection offer within 65 business days. You will have 20 business days to accept it.

Your connection contract starts when the offer is accepted.

What happens if I decline your connection offer?

If you decline to accept the connection offer, or don’t return the signed connection offer within the set timeframe, our connection offer will expire. If you still want your new system connection, you will need to submit a new connection application and go through the whole process again (including paying any fees again).

More information about connection establishment contracts

Your new connection contract will be on the terms of your accepted connection offer. It’s called a connection establishment contract.

Basic connections

For basic connection services, the terms of the connection establishment contract are listed in the schedule to our Model Standing Offer for Micro EG Units (PDF 306.1 kb).

We will make a basic connection offer where:

  • Power supply is available (that is, there is a line available at the required voltage with sufficient capacity to connect your proposed system)
  • There is little or no work required on our network for connection of solar PV systems and other micro embedded generating units.

The types of basic connections for micro embedded generating units are outlined in our basic connection services FAQ.

Negotiated connections

For negotiated connection services, we’ll negotiate the terms of your connection contract with you. Here is an example of what your Negotiation Connection  Contract (PDF 702.3 kb) will look like.

More information about ongoing supply connection contracts

Once you have accepted the connection offer and your connection establishment contract is in place, another contract automatically comes into effect for your ongoing connection services.  Unless you specifically negotiate the terms of this other contract, it will be on the terms of the relevant contract below (depending upon whether you have a card-operated meter or not):

What is a service line?

A service line is the wire that runs from our network to just inside your property and connects electricity to your premises. A standard overhead service line may extend up to 20m inside your premises, whilst a standard underground service line may extend up to 7m inside your premises.

We provide standard service lines free of charge.

What are capital contributions?

A capital contribution is a fee you’ll be charged for some types of network changes, if we need to change our network for your connection.

A capital contribution for network extension may be applicable for connections that exceed the scope of a typical connection, such as where the service line is longer than the standard service line.

A capital contribution for other network changes may also apply if the new connection or connection alteration exceeds the network change charge threshold, currently set at:

  • 10 kVA on SWER lines
  • A maximum capacity of 80 amperes on 3 phase low voltage supply on our main grid (non-SWER lines).

In these circumstances, any capital contributions will be calculated using the formula set out in section 2.6 in our Connection Policy (PDF 580.0 kb).

What is Chapter 5A?

Chapter 5A of the National Electricity Rules sets out the process for most of our customers to either:

  • Create a new connection to our electricity distribution network
  • Change an existing connection to our electricity distribution network.

The services we provide for these are called connection services.  These generally include the design, construction and energisation of connection assets and any necessary change of our network.

What are contestable services?

Some services are open to competition and can be provided by persons other than us.  These include:

What are my rights and obligations?
