Information for developers

Apply for a new or upgraded electricity supply by completing this form.

The following information is for people wanting a new electricity supply or to upgrade an existing supply.

How long will the process take?

Applications for large capacity supplies are processed within 20 working days, and construction will depend on the nature of the work, assets required and resource availability. Large network components such as transformers and switch units typically take 6-10 weeks to arrive from the manufacturer. Any shutdowns of the network to enable connection require 15 working days’ notice. Connections requiring more complex work, such as feeder line extensions or substation upgrades can take a minimum of six months. A new substation takes at least two years to consent and build.

Selecting a contractor

You must arrange for the work to be quoted and built by a Powerco approved contractor. These contractors meet Powerco standards to work on the electricity network. You can obtain quotes from more than one contractor.

A list of Powerco approved contractors can be found here


The quote from the contractor will consist of two components – the customer contribution and Powerco’s contribution, which is paid to the contractor when the work is complete.

Size or capacity of supply requirements such as fuse size, transformer size and the existing consumption pattern can affect costs. Existing capacity of the electricity network may also have an impact.

Ownership of equipment

Powerco usually owns all the equipment up to customers’ property boundary any transformer or high voltage switchgear located on customers’ properties. We are responsible for the ongoing maintenance, operation and replacement of these assets. All other equipment inside the customers’ property is usually owned and maintained by the customer.


Powerco-owned equipment within private properties that supply two or more customers, or that crosses through another property, will generally require an easement. An ownership agreement is likely to be used when only one customer is being supplied. Powerco’s approved contractors will provide you with the relevant documentation as part of their quotation. Your connection will be livened once Powerco receives the completed documentation back from you.

Energy retailer

Powerco is an energy distributor and does not sell electricity. Electricity retailers sell electricity to customers. You will need to choose a retailer, or discuss your requirements with your existing retailer who will arrange for metering and for your connection to be livened.

Electricity tariffs

Network electricity prices include the cost of transporting electricity along the Powerco network. These charges are billed directly to your electricity retailer. For most customers there are two components to these prices:
• A fixed daily charge
• Variable changes - a network charge applied to each unit of electricity consumed

Your retailer adds these amounts to their own charges to make up the final bill you receive each month.


Installing and connecting streetlights and their cables MUST BE carried out by a Powerco Approved Contractor (PAC). You can find one here

Your PAC will work through your streetlight requirements and provide you with the necessary paperwork, which needs to be filled in by:

  • Yourself – developer
  • The local council
  • The council’s electricity retailer

This is so the council and their retailer are aware of the proposed lighting, as the council may be responsible for the on-going maintenance and electricity costs of the streetlights.

You’ll need to return the completed paperwork to your PAC before we can approve the streetlights to be installed, connected and livened.
