Distributed Generation

Installing your own solar panels, wind turbines, or mini-hydro and want to connect to Waipā Networks for reliability or to feed excess power back into the grid? Let us know so we can help ensure it’s safe.

Distributed Generation is when you generate electricity for your own use. However, you can connect to Waipā Networks and supply surplus electricity back into the network.

Examples of distributed generators include

  • Solar panels
  • Diesel generators
  • Microturbines (wind)
  • Gas turbines

We support the development of safe and reliable Distributed Generation. Please see the details below if you want to connect any Distributed Generation.


“Congestion” happens when there’s a bottleneck somewhere in the network, i.e. when a line or transformer reaches its limit and can’t carry any more electricity, it’s “congested”.

Our network is currently considered uncongested in all areas and we do regular assessments to identify areas of potention future congestion.  We’ll keep you posted about any congested areas on our network.

Waipā Networks approved inverters list

An inverter is just one of a number of electronic devices that control power flow. The basic idea behind inverters is that it switches DC inputs back and forth very fast. It turns DC inputs into AC outputs.

If you’re installing inverters, they must comply with AS4777. Here’s a list of Waipā Networks-approved inverters.

Regulated terms

We have regulations that apply to distributed generation. The regulations allow distributed generation to be connected as long as the connection and operation standards are met. The regulatory framework for connecting distributed generation is laid out in Part 6 of the Electricity Industry Participation Code (“Code”).

This code will apply in most distributed generation connections (once completed). However, Waipā Networks and the distributed generator may enter a connection contract anytime. These contract terms shall take precedence.

If contracted terms cannot be negotiated and agreed upon within 30 days following notice to Waipā Networks of the intent to form a contract, the Regulated Terms will apply. Any changes to the contract must be agreed upon by both parties.

Distributed Generation Policy

Apart from the regulated terms, the installation of your distributed generation must also comply with the Waipā Networks Distribution Policy which can be found here.

Electricity prices

When it comes to ongoing electricity charges, we recommend you read our March 2016 customer newsletter and April 2016 Pricing Schedule to ensure you are fully informed.  These can be found by clicking here. Please contact us if you have any queries.
