Embedded Networks facilitating cheaper electricity for industrial and commercial buildings

What is an Embedded Network?

Put simply, an embedded network is a supply arrangement where a site owner or manager purchases electricity for an entire site and on-sells it to each tenant. An embedded network is a network established to effectively read and charge electricity to individual tenants (within a body of tenants) for the amount in which they’ve each consumed. These networks facilitate the energy on-selling process, whereby energy is purchased at a discount at the parent meter and sold to tenants within a network, again at a discounted rate, reducing overall expenditure.

An embedded network is established to physically aggregate the energy consumed within a complex, to one single meter point (commonly referred to as a parent, gate or main meter), that records the total energy consumed within the embedded network. Sub-meters then measure both tenant’s and common areas (energy consumed for public light, power and mechanical services) electricity consumption, using the latest in interval metering technology.

Embedded networking can only be established where electricity infrastructure is privately owned and managed. Rather than each occupant negotiate their own contract with various electricity retailers, they combine their purchasing power to obtain significant discounts with their electricity, to what they could all individually achieve. The volume of electricity they would use as a whole allows individual tenants of multi-unit developments to bundle their volume of electricity usage and receive discounted electricity prices, improving efficiency and lowering costs.

Embedded networks have proved highly effective in shopping centres, large scale residential developments and commercial and industrial building complexes.

Commercial & Industrial Embedded Network Systems

There has become a growing need for commercial buildings to measure electricity consumption at a tenant level, for accurate and reliable on-billing.

An embedded network system can be created where a building containing a number of tenants is fed through a single supply point, like a main switchboard. A parent meter is installed between the incoming supply and the main switchboard, recording all incoming supply to the building. The site or building owner then purchases electricity at the parent meter (as a large market user) and on-sells the energy to tenants, at small market rates. The parent meter of the site will reside with a local network service provider (LNSP), whilst the tenant meters are separated from the local provider and converted to other sub-meters. Any tenants within the site who choose to not be a part of the embedded network system will have a child meter connection to the local provider.

Benefits of Embedded Networking

The benefits associated with an electrical embedded network system include:

  • attractive rates to end users through a building-centric buying group which equates to lower energy costs for the tenants
  • additional revenue stream for building owners and managers
  • a clearer insight for building owners and facility managers of the electricity consumption across their site(s)
  • an ongoing income stream that will help to subsidise electrical building maintenance for owners and managers as buildings age and require more maintenance
  • a strong understanding of the requirements of each building, resulting in an improved ability to service tenant electrical upgrade needs and provide a low-risk arrangement for stakeholders
  • better energy monitoring and management with greater control of site electrical infrastructure including tenant metering.

Prolux Electrical Contractors have provided embedded network metering solutions for industrial and commercial estates and complexes across Melbourne, working directly with facility and building managers to ensure they deliver solutions that fulfil the needs of all users.

Working directly with switchboard manufacturers to integrate their metering solutions into the switchboard prior to delivery to site, they are able reduce the amount of on-site work required.

Goodman Property Services saves thousands with Interval Metering

Case Study: Interval Metering


Client: Goodman Property Services
Location: 50 Park West Drive, Laverton VIC
Project Value: $26,000
Project Summary: Installation of Interval Metering System to divide a 16,200sqm Warehouse/Office, into four separately metered leasable areas.


Goodman Property Services owns a 16,200sqm warehouse that was partially leased and due to market demand for smaller warehouse configurations, Goodman wanted to divide the remaining space into four smaller tenancies.

Goodman approached Prolux to install Interval Metering throughout their warehouse. An alternative solution to Interval Metering would have been supply authority metering, at a cost in excess of $60,000 for this particular property. The Interval Metering option offered a substantial cost saving, with minimal disruption to the existing tenant.


Prolux were specifically contracted to install three Current Transformer Interval Meters to connect in with the existing installation. The meters were to accurately separate mechanical services, light and power from the main tenancy. Due to the specific demands of tenants moving in, the project needed to be completed within a ten day timeframe. In addition to this, it was imperative that the power supply for the existing tenant wasn’t interrupted during business hours, or for more than a two hour period. Prolux were able to schedule the project during normal working hours with only one, one hour power interruption to the existing tenant. If supply authority meters were installed, the tenant would have been without power for up to 12 hours.

“Prolux have completed many of these Interval Metering projects and have the skills, knowledge and contacts to accurately set-up and program the interval meters.”


The project has now been successfully completed. The Interval Meters are set-up to be remotely read, allowing the Interval Metering Software to automatically generate bills for the additional tenants. This provides a seamless billing process and allows the existing tenant to retain their existing electricity supplier.

One significant benefit for the existing and new tenants is the price per kWh is based on the combined power usage of all the tenancies. It is estimated this may result in an electricity usage saving of over $3,000 per tenancy per annum, plus further future savings on reduced electrical maintenance costs.

In addition, there was a significant saving to Goodman of over $33,000 by selecting the Interval Metering solution, rather than proceeding with separate supply authority CT meters.

Interval Metering for Additional Tenants

Do the buildings you manage have adequate meters serving your tenants? Looking at dividing an area into sections for additional tenants?

Adding additional meters is a costly and disruptive exercise. There is an alternative solution – Interval Metering.

Interval metering works the same as if a full metering upgrade was carried out on a property, however at a far less cost, with minimal disruption.

Additional meters are added to the existing installation, and each new meter is assigned to each new tenant. At the end of each quarter, all tenants are billed by an electrical retailer – exactly the same as if the works were carried out in the traditional manner.

What are the benefits of Interval Metering, as opposed to traditional Billing Meters?

• Interval Metering can be retrofitted to most existing installations
• Upgrading the existing installation to meet the current regulations is not required
• Booking in the works doesn’t require the services of the power companies (or their associated costs)
• There’s a quick turnaround from the pricing stage to the completion of works (no more than two weeks)
• Costs are generally less than half – typically, by adding two additional meters to a single tenancy it would cost approximately $7,500. Interval Metering on the other hand would only cost around $3,000

Prolux Electrical Contractors are specialists in Interval Metering, managing the entire process from concept to completion.

“Costs are generally less than half.”
