Connecting DG equipment of 10kW or less

Most residential installations will fall into this category.

The first step is to ensure your equipment and its installation complies with our Network Connection Standard . Generally, the company providing the equipment will oversee this process, but check with them to be sure.

Congestion may exisit in the network area so to connect distributed generation (DG) equipment of 10 kilowatts or less, contact Centralines to discuss your plans prior to installation.


Export congestion information

Unison regularly updates information regarding areas of the Network affected by congestion. There are no specific locations or parts of Unison's low voltage network currently known to be or reasonably expected to become subject to export congestion within the next 12 months. For Unison's Congestion Management approach click here

If your proposed system's inverter is not already approved by Centralines you will need to apply to connect prior to installing your system. If your inverter is already approved, you can go ahead with your installation and apply to Centralines when you are ready to connect.
