If you are thinking about solar, this handy tool can calculate the expected benefits unique to you. Once you have chosen your system, you’ll need to find an installer. Please check they are a registered electrical worker and have experience installing generation systems.

To ensure our electricity network can support the connection of your system, you need to apply for a new DG connection with us. As technical information is required, it’s a good idea to have your electrician or electrical consultant complete the application on your behalf.

For Distributed Generation 10kW or less there are two different application pathways. These pathways are prescribed by the Electricity Authority. To determine the correct pathway please refer to section 2.3 of our DG Connection Policy.

Once we receive your complete application, we will raise an invoice for the appropriate amount and send it to the person nominated in the application. Our fees are outlined in section 3.1 of our DG Connection Policy.

After we have received payment, we’ll start reviewing your application.

Provided the application is complete and MLL is satisfied the system complies with our connection standards, we will issue notice of final approval. The default regulated terms found in Schedule 6.2 of the Code will apply.

You must not connect your distributed generation to the MLL network without written approval.

Note: Even though someone may be acting on your behalf, the contract that is formed by proceeding with the connection is between the customer and MLL, and it is important you understand your connection contract.

Following notice of approval, you may begin installation or alterations to your system.

Important: Your installer must leave your system switched off until the metering has been replaced or programmed to measure export. Before the system is turned on you should talk to your installer about how to do this safely.

DG installations require an electrical inspection by a registered Electrical Inspector as it is defined as high risk prescribed electrical work in the Electricity (Safety) Regulations. Your installer should arrange this for you.

We may visit your premises to inspect your system to confirm it matches your application and meets safety and electrical standards. We may inspect your system after installation, as part of an audit, or if there's potential for your system to have an impact on our network.

It's important that any system changes such as changing settings, swapping your inverter, or adding panels or batteries are approved by us before an installer makes the changes. You'll need to submit a new application for these changes.

MLL is responsible for ensuring that it has plans and records of DG installations to ensure the safe and reliable operation of our network. The testing and commissioning report and supporting documentation (detailed in our standards) must be returned to MLL within the required timeframe.

For all Small Distributed Generation, the installer shall follow MLL’s commissioning test form online: F37 - LV DG IES Commissioning Form (200kW and less)
