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 and policy for Connection of Distributed Generation. Generally, the company providing the equipment will oversee this process.
To connect Distributed Generation equipment of 10 Kilowatts or less, you’ll need to check whether congestion in the area of the Network exists, and if so contact Unison to discuss your plans prior to installing your distributed generation.
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.
