How advanced meters and the smart grid system work together


An example of how the grid works

If the power is lost to your home your advanced electricity meter creates a message that says, 'the power has gone out in this home'.

Wireless signals are then passed from house to house to house until they reach a centralised place called a 'take out point' in your neighbourhood.

Data is collected at that 'take out point' and transported back to Network Tasman’s office in Hope. We can see immediately where the fault is and exactly how many homes are affected.

Network Tasman’s computer system processes the information and our call centre responds by dispatching a someone to address the problem.  

While we still encourage consumers to ring us when they experience a loss of power supply, in the future advanced meter technology will mean that you won’t need to call to tell us your power is out. This feature will speed up fault restoration times significantly.

Your advanced meter will also store a range of information that can help Network Tasman solve any electricity supply problems in your area. For instance:

  • If we suspect a problem in your area we could ask your meter how many problems your home has experienced recently and how many problems the homes around you have experienced.
  • Network Tasman could then compare this information with other messages coming from other parts of our system to accurately pinpoint problems.  Having this information will help us speed up the work required to solve any issues.

Radio frequency fields

Some people have expressed concerns about radio frequency fields and wireless communication in general. If you have concerns, a good place to start is to watch our video below.

A great deal of research has been done in the field of wireless communication. Our understanding is that no evidence of any adverse health effects from advanced meters has been demonstrated in peer-reviewed, science-based research published in reputable scientific publications.
