1. why a single point of supply?

3. application for supply - to retailer

5. supply to individual units
1. why a single point of supply?
Historically, it has been cheaper to install Energex electricity supply within community titles developments, because Energex has provided transformers
and cables free of charge. This is now changing. From 1/7/09, there will be no Energex subsidy for new subdivisions.
However Energex will continue to subsidize the augmentation of electricity supply to existing lots.
This an anomaly. What is its significance?
For very small developments, when a new transformer is not required, it will still be cheaper to install Energex electricity cables through the estate.
On the other hand, if a new transformer is required for the community titles development, the most economical approach will usually be:
- In the subdivision phase: in order to obtain a Certificate for Electricity Supply for the community titles lot, install a single electricity pillar.
- When the community titles development is constructed: provide for a privately- owned electrical installation internally, to take electricity from a single point of supply.
Robin Russell & Associates will handle the first step for you. The second step is your responsibility. However we can help if requested.
Certainly, we shall advise you regarding the most economical approach in every case.
2. connection application - to energex
When you have a firm program for construction, start by phoning Energex's Call Centre on 13 12 53.
Tell them:
- the enquiry concerns: "supply availability"
- it is for a community titles development
- address of the site
- name and details of contact person
Energex's Call Centre will assign a Work Request Number, then refer the enquiry to Energex's Network Service Centre.
The Network Service Centre (Greg McCabe or one of his associates) will then phone/contact you to obtain full details of the proposed community titles development, i.e. how many units, how prestigious, whether air-conditioned, etc., to estimate likely load.
The Network Service Centre will access your requirements and create a Project, if supply is not already available from the existing network. They will send this to Energex's local Hub, for design and construction.
The Hub will prepare a design. If a new transformer is required, they will write to you, with details of the required site and foundation. It will be your responsibility to prepare the site and construct the foundation. (Electricity Regulation 2006 S. 57 empowers Energex to demand space for a substation if the calculated electricity demand exceeds 100kVA. That covers most town house developments of more than 10 units.)
The Hub may also request a capital contribution (payment) from you, if the cost of their project is too high in relation to anticipated future revenue. (Don't ask how this is calculated. No one at Energex can tell us. It is a very complicated formula, hidden in the bowels of their computer.)
If a substation (transformer) site is required, the Hub will also send you a Form 2226: Proposed Electricity Supply Arrangements, which sets out details of the proposed electricity supply, i.e. transformer, substation site, etc. You should check this carefully, then, if it is correct, sign it and return it to Energex. This is your consent for Energex to construct the substation and install their cables on your land.
3. application for supply - to retailer
Not more than one month before the installation will be ready to be connected, lodge an Application for the Supply of Electricity with your selected Electricity Retailer. This can be done via the Internet, by fax, or by telephone.
You will be applying for the supply of electricity for community power. The Body Corporate will be the eventual electricity customer, but initially there will be no Body Corporate, so the applicant will be the developer.
When lodging this application, please ensure that the following details are supplied very precisely and completely:
- name and address of customer (who will pay the electricity bills)
- installation address (including additional information that this is community power)
- real property description of the common property
- date you expect to require electricity supply to be connected
Ask the Retailer for their Retailer Service Order (known as a B2B) number.
The Electricity Retailer will send the B2B to Energex. Energex will hold the B2B, awaiting receipt of a Form 2 from your electrical contractor.
4. form 2 - from contractor to energex
Robin Russell & Associates does not design private electricity installations, to comply with AS/NZS 3000:2007. This would normally be done by your building services electrical contractor, who would design and install the electrical installation, starting at Energex's point of supply. For a large development, however, you might choose to engage an electrical consultant to design the installation, and possibly supervise the electrical contractor who would construct it.
When the installation is ready for connection, the electrical contractor must lodge a Form 2: New Electrical Work Request with Energex.
To ensure that Energex can match the Form 2 with the Retailer's B2B, it is very important that the Form 2 contain identical details with the Application which you lodged previously with the Retailer. So you must give the following to the electrical contractor as soon as possible:
- copy of Energex's Form 2226: Proposed Electricity Supply Arrangements
- copy of the Application for Supply of Electricity which you lodged with the Retailer
- Retailer's B2B number
Energex will connect electricity supply to the main switchboard. This will provide community power supply.
5. supply to individual units
If each unit has individual electricity meters, a separate application for electricity supply will be required for each unit. Unit owners can choose their own preferred electricity retailer.
