Increase small commercial connection
Who is this for?
If you want to upgrade the electricity supply at your commercial property to a maximum demand of 250A/180kVA.
How long will it take?
3 months to provide you with a technical assessment
4-6 months to provide you with a design and quote, depending on the complexity of your project
3 months to construct, upon payment of quote and confirmation your site is ready
How much will it cost?
We'll provide a quote after we complete the scoping and design of your project.
|Application fee (plus 0.59% credit card surcharge)||$497.42|
* While the design fee is GST inclusive, the GST exclusive amount will be deducted from the access offer if proceeding, i.e. GST is not refunded
|Construction costs||We will provide a quote|
The cost of an electricity supply is dependent on how much power you require. In most cases, the cost will be based on what we call the Distribution Low Voltage Connection Scheme.
Perhaps you've bought a brand-new piece of equipment that needs more power than you currently have, or you've moved premises and the power needs upgrading to suit your business needs. If you're a small or medium business looking to modify your current supply, you can find everything you need to know including information relating to underground power, administrative costs and any other fees and charges included.
You’ll receive a scope
You’ll receive design fee invoice
You’ll receive a quote for the delivery of the works

What to include with your application
A CAD site plan
Your CAD plan helps us better understand your work site and location of assets. We extract data from your plan to assist us with your design.
For a CAD site plan to be accepted, it must clearly show:
- the proposed pillar location in a visible colour on the site plan.
- the street name on which the property borders
- the full address of the property
- the nearest intersection (for rural properties it helps to locate the site)
In order to provide a fast, accurate quote and advice on your new connection arrangement we require a comprehensive site plan with details of your current and/or proposed site layout. This includes but is not limited to the following information being clearly marked on your plan:
- boundary or retaining walls at the side and front of the property – including depth of wall
- location of items such as letterboxes, garden beds, trees/stumps, driveways, crossovers
- detail or grades of any major inclines or slopes near the front boundary
- utility locations for water meters/pipes, gas pipes, sewer mains/connections and access points
- proposed location of new pillar/s
Example site plan
Pillar exclusion zone
The pillar needs to have an exclusion zone of 50cm from its centre. Inside or under the exclusion zone there must not be any:
- water pipes, water storage facilities or water meters
- gas pipes or meters
- telecommunication cables
- sewage, waste water, or storm water pipes
- reticulation pipes or cables
- tree roots and other vegetation
- concrete, asphalt, limestone or bedrock
Find out what underground assets may be in the vicinity by submitting a Dial Before You Dig application.
Help us understand your current connection arrangements and more easily identify potential site specific issues. Photos will need to include:
- The extent of the worksite
- Any obstructions in the area
Site photos help us understand your current connection arrangements and more easily identify potential site specific issues. If you’re able to supply us with a close up and wide photos it will potentially reduce application times as we won’t be required to visit the site.

Single line diagram
The single line diagram provides us with the technical information to design a connection to meet your requirements.
In your single line diagram, you'll need to include:
- mains size
- number of cables per phase
- service protection device (SPD) setting and rating
- metering types
- metering quantity.
Your load breakdown allows us to assess the impact your project will have on the network. It also allows us to apply the appropriate charging policy.
The information allows us to check the impact of your loads on the network. You must comply with Power Quality limits as per AS/NZS 61000.3.11, SA-SNZ TR IEC 61000.3.14 and Western Power Technical Rules.
