Installing and Connecting Distributed Generation to Network Tasman's Electricity Network
Distributed Generation means using equipment for generating electricity at a home or business which is connected to an electricity distribution network (i.e. Network Tasman's electricity network) that is capable of injecting electricity back into that network. Examples of distributed generation include; solar (photovoltaic), wind, diesel generator, fossil fuel, hydro and battery.
Installing distributed generation can be complex and each situation is different. If you intend to purchase and install a distributed generation plant at your home or business, we recommend you involve us in the process as early as possible before you purchase the plant.
There are a number of regulations that apply to distributed generation. It is important that you are fully aware of what is required before you invest in any plant.

Conditions for Connection
Distributed generation must meet all relevant statutory and regulatory requirements and comply with all applicable safety standards. Network Tasman's policies and procedures for the application for, installation and connection of Distributed Generation are in accordance with the requirements of
The Regulated Terms specified in Part 6 of the code will apply to the majority of distributed generation connections (once approved and completed). However, Network Tasman and the distributed generator may enter into a connection contract at any time and these contract terms shall take precedence. If contracted terms cannot be negotiated and agreed within 30 days following notice to Network Tasman of the intent to form a contract then the Regulated Terms shall apply. Any changes to contracted terms shall be by mutual agreement.
Network Development Levy - If the proposed generation is likely to lead to future network congestion, the generator may be required to pay a Network Development Levy to contribute to the cost of network reinforcements.
Conditions for Connection
The connection conditions and distribution code detail the technical requirements and conditions that all generation plant connected to Network Tasman's distribution network must comply with.
With the continued growth in distributed generation, significant amounts of energy can be exported into the network particularly in the summer when people may be at work or away from home.
The growth in the amount of exported energy has the potential to create reverse power flows and congestion on our network. One possible consequence of this is higher than standard voltage, which can damage consumers' appliances and equipment. To limit the effect of this, all inverters are required to have an overvoltage shutdown facility and this is currently to be set at 246V.
In some instances, events on Transpower's national transmission grid may restrict distributed generation.
At present, our network is accommodating distributed generation without congestion in most areas. There are some areas however that have reached their capacity for hosting solar generation.
No further distributed generation can be accommodated in these areas without export to grid restrictions or network upgrades. Installers considering adding solar generation in these areas should contact Network Tasman before making any offers to their customers.
We will notify you if we think your distributed generation is likely to cause congestion.
