New electricity connection

Application process for Remote Communities

Application process

This application will help us understand the requirements for your electricity supply. It is important to complete all relevant fields to avoid delays in receiving the design and quotation.

If you are an electrical consultant/ contractor, you must have written authorisation from the applicant to act on their behalf.

Assessment and fees

Within 5 business days of receiving a complete application, we will issue a design fee invoice of $6,600 (for connections between 30kVA and 1mVA). The design fee will be deducted from the formal quote if you proceed with the project but is otherwise non-refundable. 

There is no charge if the size of your connection is less than 30kVA.

Design and formal quote

After receiving payment of the design fee, we will issue you a design and formal quote for the connection works within 60 business days.

If a capacity assessment is required it may take up to 90 days to recieve your design and quote. 

Accept quote

If you wish to proceed, sign the Quote Acceptance form and return it to us within 30 business days. 

We will issue a construction invoice for the work which will need to be paid before any work can be scheduled.

Connection details

What type of connection do you require? Commercial and Industrial properties have very different electricity needs and are more complex in nature.
Please enter the date from which you require supply to commence. Please allow a minimum of three months from receipt of payment of invoice for connection to be provided by Horizon Power.


Estimated total maximum demand

Provide you estimated load profile and any other relevant information about your connection. Both kVA and Amps/phase are accepted.
Provide you estimated load profile and any other relevant information about your connection. Both kVA and Amps/phase are accepted.

Estimated total consumption

Load pattern

Monday to Friday or seven days a week


Supply arrangement options Low voltage supply: These substations are generally suitable for loads up to 2MVA. Horizon Power owns and is responsible for all equipment within the substation. High voltage supply: These options are generally suitable for loads above 1MVA. The customer owns and is responsible for all equipment within the substation other than Horizon Power's metering unit and any high voltage switches connecting the substation to the Horizon Power network. Supply with higher levels of security: Please tick this option if you require a power supply arrangement with a greater level of security than is offered by the standard arrangements above.
Low voltage power supply options
High voltage power supply options


Do you require a CT meter? CT (Current Transformer) meters are installed on any connections with a load greater than 100 Amps. A CT meter only measures a fraction of the current passing through the connection and a multiplier is applied to this reading to reflect the actual current.
Are there multiple units?


Equipment details


Power converting equipment

Arcing devices

Magnetic core equipment

Power factor correction or harmonic mitigating equipment

Request quote

Request to provide a formal quote

Before you submit this application, please carefully read the information on this page. If you are a contractor or any person other than an applicant and you are submitting a new connection application or supply upgrade application (Connection Application) on behalf of the applicant, by completing and submitting a Connection Application you:

3. Design fee

A formal quote is free of charge for connections that will have a total maximum demand of 30 kVA or less or projects that only require relocation of Horizon Power assets.
A design fee is payable for connections with a total maximum load of more than 30 kVA or connections which will require CT metering that will result in an increase in the load capacity at the relevant site. The design fee is specified in the Fees and Charges section of Horizon Power’s website at Horizon Power will issue you with a tax invoice for the design fee (if applicable) after Horizon Power receives the completed Connection Application form from you. Horizon Power will only commence preparation of the detailed design and formal quote when this fee (if applicable) is paid.
