Your development may be a large commercial or industrial complex with significant demand for Electricity. 

A large customer is defined as a Connection Applicant with:

• An estimated annual electricity consumption greater than 4GWh per annum, or
• An estimated maximum demand greater than 1MVA, or
• Significant connection assets, or
• A generating system with nameplate capacity greater than 30 kVA.

Design and construction of large connection assets is determined to be contestable. Connection Assets are those “dedicated” high voltage and low voltage assets required to connect an installation to the Energex Network.

Large Connection Applicants shall pay the cost of design and construction of new Connection Assets. On completion of construction, Connection Assets may then be gifted to Energex. Gifted assets shall be owned, operated and maintained by Energex.

You must engage an accredited Energex electrical engineering consultant to investigate the Energex network arrangement and determine the most cost effective method of providing electricity supply to the development.

Our electrical engineering consultants undertake the following:

• Review the council decision notice and development footprint,
• Consider council planning requirements,
• Review existing electricity supply arrangement,
• Consider Large Customer Connection manual,
• Consider Energex Supply and Planning manual,
• Consider whether existing Energex assets will be impacted by the development,
• Develop a suitable electricity supply arrangement,
• Submit Energex Connection Enquiry,
• Receipt Energex concept and parameters,
• Produce and preliminary design for discussion with other Engineering professions,
• Coordinate with other engineering professions,
• Produce a detailed design showing the proposed connection arrangement,
• Prepare an operational works submission for council (if required),
• Call tenders,
• Prepare an Application for Energex,
• Receipt an Energex Project Connection Contract,
• Liaise with the client to execute the contract and pay Energex fees,
• Advise the client of their responsibilities,
• Administer the project on behalf of the client.

The client must engage an accredited Energex service provider to undertake construction of the electricity reticulation.

The client’s project manager will arrange identification of substation site, easements, relevant boundaries and liaise with accredited Energex service providers with regard to site availability, timing and duration of works.

The principal’s surveyor is to peg all boundaries prior to construction and after construction to prove accuracy of asset installation.
