Key takeaways:
Choosing between an embedded network vs individual meters can have long-term consequences for electricity costs, administration, retailer choice and energy management. This decision is particularly important for commercial buildings, shopping centres, apartment developments, industrial estates and other multi-occupancy properties.
An embedded network typically involves electricity entering a property through a central connection before being distributed to individual occupants. Individual retail connections, by contrast, generally give each premises its own connection and electricity retail arrangement.
Although both structures allow individual electricity consumption to be measured, they create very different commercial and operational arrangements. Therefore, property owners, developers and businesses should understand the differences before selecting a connection model.
An embedded network is a private electricity distribution arrangement within a larger property or development. Electricity is generally purchased through a parent connection and then distributed through private infrastructure to individual occupants.
Sub-meters measure how much electricity each tenant, business or resident consumes. The embedded network operator or another responsible service provider then manages relevant metering, billing and network administration.
Embedded networks are commonly associated with multi-tenanted developments because they enable electricity arrangements to be managed across a site rather than treating every occupant as a completely separate connection.
With individual retail connections, each premises generally has a direct relationship with an electricity retailer. The retailer bills that customer according to the applicable electricity plan, meter data and network charges.
This arrangement gives individual customers greater responsibility for choosing and managing their electricity contracts. Consequently, the property owner usually has less involvement in individual electricity purchasing.
The fundamental difference is not simply the physical meter. Instead, the key distinction concerns how electricity reaches occupants and who manages the commercial relationship.
| Factor | Embedded Network | Individual Retail Connections |
| Electricity purchasing | Often centrally arranged | Arranged by each customer |
| Metering | Individual sub-meters generally used | Individual retailer-recognised meters |
| Billing | Managed within the network arrangement | Retailer bills customer directly |
| Retailer choice | May be more complex or restricted in practice | Generally greater flexibility |
| Administration | Centralised | Distributed across occupants |
| Shared energy assets | Easier to integrate in some developments | Can require additional coordination |
| Energy procurement | Potential for aggregated purchasing | Each customer negotiates separately |
| Property involvement | Higher | Generally lower |
Therefore, neither option is automatically better. The appropriate structure depends on the site's objectives and operating model.
One potential advantage of an embedded network is the ability to aggregate electricity demand. A large property may have greater purchasing leverage than many small customers negotiating separately.
However, bulk purchasing does not automatically guarantee lower costs. The outcome depends on electricity consumption, contract terms, network arrangements, administration costs and the quality of the procurement strategy.
Energy procurement should therefore form part of the decision rather than being considered after the network has been established. Businesses should understand their consumption patterns and compare appropriate electricity contract structures before committing to long-term arrangements.
The lowest electricity rate does not necessarily produce the lowest overall cost. Property owners should also consider:
As a result, a whole-of-life cost assessment can provide a more useful comparison than looking only at initial installation expenses.
A major attraction of individual retail connections is customer autonomy. Occupants can generally choose a retailer and electricity plan according to the options available to them.
This model can work well where occupants have very different consumption patterns or commercial priorities. Furthermore, the property owner does not need to coordinate a central purchasing arrangement for every occupant.
An embedded network introduces another layer between the incoming electricity connection and individual customers. Therefore, customer rights, billing processes and network responsibilities need to be clearly managed.
Australian embedded network arrangements are also subject to regulatory requirements that can vary depending on the jurisdiction, network structure and type of customer. Consequently, property owners should obtain appropriate regulatory and technical advice when designing or changing an embedded network.
An embedded network can offer significant advantages where a property owner wants a coordinated approach to energy.
For example, centralised consumption information can help identify peak demand, unusual usage and opportunities for efficiency improvements. Property managers may also find it easier to develop a site-wide energy strategy when the building's electricity infrastructure operates as an integrated system.
Individual connections provide a different advantage. Each occupant can make decisions according to its own energy requirements without relying on a central procurement strategy.
Therefore, the choice comes down partly to whether the property benefits more from central coordination or individual autonomy.
Modern commercial and residential developments increasingly incorporate solar generation, batteries and electric vehicle charging. An embedded network can provide a framework for coordinating these technologies across multiple occupants.
For instance, rooftop solar generation may support common areas and participating occupants. Battery storage may also help a site manage when electricity is drawn from the grid.
However, the financial and technical structure needs careful design. Metering arrangements must accurately record consumption, while commercial agreements should establish how costs and benefits are allocated.
Individual retail connections do not prevent occupants from adopting renewable energy. However, shared infrastructure can become more complicated because multiple electricity accounts and connection arrangements may be involved.
For properties planning significant shared energy infrastructure, this consideration should form part of the initial network design rather than becoming an afterthought.
Large multi-tenanted commercial sites may benefit from an embedded network where centralised procurement and energy management create sufficient value.
A shopping centre, for example, could have substantial combined electricity demand across common areas and tenants. Aggregating this demand may create opportunities for a coordinated procurement strategy.
Nevertheless, an embedded network also creates management responsibilities. The operator needs appropriate systems for metering, billing, customer enquiries and compliance.
Individual retail connections may be preferable when tenants value independence or where the property owner wants minimal involvement in electricity retail arrangements.
The same trade-off applies to apartment buildings and mixed-use developments.
An embedded network may provide a platform for centrally managed electricity services and shared energy technologies. Conversely, individual retail connections can provide residents with a more conventional electricity relationship.
Developers should consider the long-term implications because the connection structure can affect residents and owners well after construction finishes. Therefore, future retailer access, technology upgrades and ongoing administration deserve attention during the design phase.
Before deciding between an embedded network vs individual meters, property owners and businesses should examine several questions.
First, how much electricity does the site consume and when does that consumption occur? Understanding demand profiles can help determine whether aggregated procurement provides meaningful benefits.
Second, who will manage the arrangement? An embedded network requires ongoing administration rather than simply installing meters and leaving them unattended.
Third, how important is retailer choice to occupants? Different tenant or resident groups may have different expectations.
Finally, what will the property need in five or ten years? Solar generation, batteries, EV charging, expansion and changes in tenancy can all affect whether today's network design remains suitable.
One common mistake is comparing the options purely on upfront infrastructure costs. A cheaper installation may create greater administration or upgrade costs later.
Another mistake is assuming that an embedded network automatically means cheaper electricity. Competitive outcomes depend heavily on procurement, contract management and consumption patterns.
Businesses should also avoid treating electricity contracts as static. Energy requirements and market conditions change, so regular reviews remain important. Energy Action's existing guidance similarly emphasises assessing consumption, comparing contract structures and regularly reviewing electricity supply arrangements.
The embedded network vs individual meters decision involves much more than selecting a metering system. It determines how electricity is purchased, distributed, measured, billed and managed across a property.
Embedded networks can provide centralised control, aggregated procurement opportunities and a useful platform for shared energy technologies. Individual retail connections, meanwhile, generally provide greater independence and a simpler direct relationship between each occupant and its chosen retailer.
Ultimately, businesses and property owners should evaluate consumption, costs, administration, compliance, future technology and procurement objectives before making a decision.

The main difference concerns the electricity supply and commercial structure rather than simply whether each premises has a meter. An embedded network generally purchases electricity through a parent connection and distributes it internally, with sub-meters recording individual consumption. With individual retail connections, each customer generally has its own retail electricity arrangement and receives bills directly from its retailer.
An embedded network can create opportunities for cost efficiencies because electricity demand may be aggregated and purchased centrally. However, lower costs are not guaranteed because procurement rates, administration, metering, network maintenance and other expenses affect the final outcome. Therefore, businesses should compare the total cost of each structure rather than assuming bulk purchasing will always provide the lowest price.
Retailer choice can be more complicated within an embedded network than with a conventional individual retail connection. The practical options can depend on the site's network configuration, metering arrangements, jurisdiction and applicable regulatory framework. Property owners should therefore understand customer choice requirements before establishing or changing an embedded network.
Embedded networks can work well with shared solar generation, batteries and other distributed energy resources because the property can coordinate infrastructure across multiple occupants. However, suitable metering and commercial arrangements are needed to determine how generated or stored electricity is allocated. Careful system design is particularly important where a development plans to add EV charging or expand renewable energy capacity later.
Start by assessing electricity consumption, tenant requirements, procurement opportunities, administration resources and future energy plans. Then compare the long-term costs and responsibilities of both models, including billing, compliance, maintenance and technology integration. Professional energy and technical advice can help businesses understand these variables before committing to a structure that may remain in place for many years.
