What Is an Embedded Network, and Why Can't You Choose Your Electricity Retailer?

What is an embedded network, and why can't you choose your own electricity retailer? An embedded network is a private electricity network inside a building, estate or park that buys power in bulk through one connection to the main grid and on sells it to residents or tenants through what is called an exempt seller, rather than every property holding its own retail account with a company like Ausgrid or Endeavour Energy. If your unit, retirement village home or shop sits on one of these setups, you technically still have the right to switch retailers, but in practice that choice is far more limited than it is for a standalone house with its own meter.

⚡ Quick Answers: Embedded Networks

• What is an embedded network? A private network behind one bulk connection, usually at an apartment block, retirement village, caravan park or shopping centre, where the building owner or an operator on sells electricity to each occupant.
• Can I still switch electricity retailers? You have the legal right to, but many retailers will not take on embedded network customers because of the specialised metering involved, so real world choice is narrow.
• Who do I complain to if something goes wrong? The Energy and Water Ombudsman NSW (EWON) covers embedded network billing disputes for residential customers the same way it covers a standard retail account.
• How do I find out if I am on one? Check your bill for a seller name you do not recognise as a mainstream retailer, or ask your strata manager, park manager or real estate agent directly.
• Does being on an embedded network change who does my electrical work? No. Any work on the shared supply, the gate meter or the building's main switchboard still has to be done by a properly authorised electrician, typically a Level 2 ASP for anything on the network side.
• Is an embedded network the same thing as living in a strata building? No. Plenty of strata buildings have individual Ausgrid or Endeavour Energy connections per lot, and plenty of embedded networks exist outside strata, in retirement villages and parks.

1. How an embedded network actually works

A single connection, called the point of common coupling, brings bulk electricity into the site from the distribution network. From there, the embedded network operator or its appointed exempt seller distributes power through internal wiring to each unit, shop or site, with a sub meter at each one recording usage separately. SIRNSW Clause 4.13 covers exactly this kind of arrangement under its multiple installations rules, which is the same clause that governs duplex units, groups of small shops and factory unit developments sharing one supply point.

2. Why retailer choice is so limited in practice

The exempt seller framework technically preserves your right to buy electricity from any retailer licensed to operate in NSW. The practical barrier is that switching usually means installing a new, separately metered connection back to the distribution network, which is expensive, disruptive and needs the building owner's cooperation. Most mainstream retailers also simply are not set up to service a single unit inside someone else's private network, so the market offers you would normally compare against a standalone house rarely extend to embedded network customers.

3. What an exempt seller still has to do

An exempt seller is not unregulated. Under the Australian Energy Regulator's exemption framework, the operator must price electricity according to a published guideline rather than charging whatever it likes, provide clear information about who to contact with a complaint, and for residential embedded networks, be a member of the Energy and Water Ombudsman NSW so residents have an independent dispute path. When you first move in, the network owner and exempt seller are required to give you written information identifying the seller and how billing works.

4. How to tell if your property is on one

The clearest sign is a bill from a company name you do not recognise as one of the big retailers, or a bill that references the building's own management rather than a standard NMI linked retail account. Apartment blocks built with a shared meter room, retirement villages, caravan and residential parks, and some shopping centres are the most common examples. If you are unsure, the fastest route is simply asking your strata manager, the park operator, or the real estate agent managing the lease.

5. What this means for metering and switchboard work inside the building

Sub metering inside an embedded network still has to meet the same technical rules as any other multiple installation under AS/NZS 3000 and SIRNSW, including correctly sized and labelled service equipment, sealed or lockable unmetered submains, and clear occupancy identification at the meter panel. If your building is planning common property switchboard work, a new EV charger on a shared car space, or a smart meter upgrade across the whole site, that work still needs a licensed electrician and, for anything touching the shared supply, a Level 2 ASP, exactly as it would on a standard multi unit connection.

6. Leaving an embedded network (de embedding)

A building can leave an embedded network and move every lot to its own direct retail connection, a process generally called de embedding. This is a decision for the owners corporation as a whole, not an individual lot owner, because it involves replacing the shared metering infrastructure and coordinating a new connection agreement with the distributor. It is a genuine electrical project in its own right, not a billing paperwork exercise, and typically needs the same kind of planning as a strata switchboard upgrade.

How High Demand Electrical helps

High Demand Electrical is one of Sydney's most trusted Level 2 ASPs for the metering and switchboard work embedded networks actually involve, from gate meter and sub board upgrades to the common property capacity assessments a de embedding project needs. We work with strata managers and facilities managers across Sydney's West, South West and Sutherland Shire, not just individual lot owners, because so much of this work sits on common property rather than inside any one unit. If your building is weighing up a de embedding project or just needs its shared metering brought up to standard, book a site assessment and we will walk you through exactly what the supply side involves before anyone commits to a scope or a cost.

Embedded Network FAQs (Sydney)

Is an embedded network legal in NSW?

Yes. Embedded networks operate under an exemption granted by the Australian Energy Regulator rather than a full retail authorisation, and the exempt seller still has pricing, metering and complaint handling obligations to meet under that exemption.

Will I pay more living on an embedded network?

Not automatically, since pricing has to follow an AER guideline, but losing the ability to shop around between retailers is the real cost most residents notice, because you cannot chase a cheaper market offer the way a standalone house can.

Can a strata scheme leave an embedded network?

Yes, through a process called de embedding, but it is a whole of building decision made by the owners corporation and involves real metering and switchboard work, not just a change of paperwork. See our strata switchboard capacity guide for what that kind of project involves.

Does the embedded network operator still need an authorised electrician?

Yes. Any work on the shared supply equipment, gate meter or building main switchboard needs a properly licensed electrician, and for anything touching the network side specifically, a Level 2 ASP authorised on that distributor's network.

If your building is on an embedded network and you need the shared metering or switchboard assessed, get a power supply upgrade quote from High Demand Electrical or call 0402 559 777. Every job starts with a proper site assessment, since common property electrical work can't be accurately scoped or priced over the phone.
